Análisis de los factores pronósticos de mortalidad en los pacientes con enfermedad renal crónica en hemodiálisis / Analysis of Mortality Prognostic Factors in Patients with chronic Kidney Disease on Hemodialysis

Introducción: La enfermedad renal crónica es una de las principales causas de mortalidad en todo el mundo. La estratificación del riesgo a través del análisis de factores pronósticos podría generar un cambio de paradigma. Objetivo: Analizar los factores pronósticos de mortalidad en los pacientes con enfermedad renal crónica en hemodiálisis. Métodos: Se realizó un estudio no experimental, longitudinal de cohorte retrospectivo en los pacientes con enfermedad renal crónica en hemodiálisis en el Hospital General Docente: Dr. Ernesto Guevara de la Serna durante el período del 1 de enero de 2017 al 31 de diciembre de 2021. En general, se analizaron los factores pronósticos de mortalidad mediante el análisis multivariado de regresión logística binaria y se determinó el porcentaje correcto de clasificación del modelo de regresión. Resultados: Se analizaron como variables pronosticas de mortalidad la enfermedad cardiovascular [B = 3,831; p = 0,000; Exp (B) = 46,118], Albúmina 17 mmol/L [B = 1,326; p = 0,027; Exp (B) = 3,767], glucemia < 4 mmol/L [B = 1,600; p = 0,015; Exp (B) = 4,955] y ganancia de peso interdialítica excesiva [B = 2,243; p = 0,001; Exp (B) = 9,420]. El porcentaje global de clasificación del modelo de regresión logística binaria fue de 89,5 por ciento. Conclusiones: Se analizó el modelo predictivo de regresión logística que presentó una buena precisión con los factores de pronósticos asociados a la mortalidad en los pacientes en hemodiálisis(AU)

Introduction: Chronic kidney disease is one of the main causes of mortality worldwide. Risk stratification through the analysis of prognostic factors could generate a paradigm shift. Objective: To analyze the prognostic factors of mortality in patients with chronic kidney disease on hemodialysis. Methods: A non-experimental, longitudinal retrospective cohort study was carried out on patients with chronic kidney disease on hemodialysis at Dr. Ernesto Guevara de la Serna General Teaching Hospital from January 2017 to December 31, 2021. The prognostic factors of mortality were analyzed using multivariate binary logistic regression analysis and the correct percentage of classification of the regression model was determined. Results: Prognostic variables of mortality were analyzed, such as cardiovascular disease [B = 3.831; p = 0.000; Exp (B) = 46.118], albumin 17 mmol/L [B = 1.326; p = 0.027; Exp (B) = 3.767], blood glucose < 4 mmol/L [B = 1.600; p = 0.015; Exp (B) = 4.955] and excessive interdialytic weight gain [B = 2.243; p = 0.001; Exp(B) = 9.420]. The overall classification percentage of the binary logistic regression model was 89.5percent. Conclusions: The logistic regression predictive model was analyzed, which showed good precision with the prognostic factors associated with mortality in hemodialysis patients(AU)

Impacts of the COVID-19 Pandemic on the Mental Health and Motor Deficits in Cuban Patients with Cerebellar Ataxias.

Although there are no convincing evidences of detrimental effect of SARS-CoV2 infection on the cerebellum, the COVID-19 pandemic could impact the life quality of patients with cerebellar ataxias, but few studies have addressed this concern. To assess the motor and mental health changes caused by the COVID-19 pandemics in Cuban patients with cerebellar ataxias, three hundred four patients with cerebellar ataxias and 167 healthy controls were interviewed for risks of exposure to COVID-19, and the self-perception of the pandemics' impact on the disease progression and on the mental health. All subjects underwent the Hospital Anxiety and Depression Scale. The patients reported low exposition to SARS-CoV2 infection, but one case was confirmed with a mild COVID-19. Overall, depressive and anxiety symptoms were significantly and marginally increased in patients, respectively, with higher scores in cases with severe and moderate ataxia. Positive patient's impression of psychopathological changes was associated to increased age, age at onset, and anxiety. Sixty-seven patients had a positive self-perception of ataxia progression, which was mainly influenced by higher anxiety scores but not by the adherence to at-home exercise programs. However, the practice of physical exercise was related with lower depression and anxiety scores, but this therapeutical effect was not significantly influenced by the disease stage. We demonstrated the negative effect of the COVID-19 pandemic on the mental and motor deficits in Cuban patients with cerebellar ataxias and the positive effect of the at-home physical exercise programs on their mental well-being. These findings give rationales to develop tele-medicine approaches to minimize these health impacts and to study the long-term effects of such sequelae and accordingly define their treatments.
