RESUMO

OBJECTIVES: The aim of this study was to determine the prevalence of Motoric Cognitive Risk (MCR) syndrome, describe associated risk factors and to determine the risk of progression to cognitive impairment after three years of follow-up, in a sample of Mexican older adults. DESIGN: A prospective panel study of health and aging in Mexico. SETTING AND PARTICIPANTS: Baseline and follow-up information was obtained from the Mexican Health and Aging Study's 2012 and 2015 waves. A total of 726 subjects aged 60 years or older with normal cognition at baseline were classified into 4 groups: 1) with MCR, 2) with memory complaint only, 3) with slow gait speed only and, 4) without MCR. Cox regression analysis controlling for confounder factors was performed to determine the risk of progression to cognitive impairment in the MCR group. MEASURES: Data such as gait speed, functional status and cognitive performance (standardized by age and sex in Mexican population) was collected. RESULTS: MCR prevalence was 14.3%. When compared with non-MCR subjects, the presence of MCR was associated with older age (p<0.01), lower educational status (p=0.05), having two or more comorbidities (p<0.05) and diabetes mellitus diagnosis (p<0.05). At follow-up and after adjusting for confounders, MCR was associated with a 2.4-fold increased risk (95% CI: 1.28-4.26, p=.000) of cognitive impairment. CONCLUSIONS: MCR syndrome increases the risk of cognitive impairment in Mexican older adults. Simple measurements such as gait evaluation in subjects with memory complaints could allow early identification of those at risk of developing cognitive impairment.

RESUMO

Objetivo: caracterizar, en los ámbitos clínico y sociodemográfico, una población de pacientes con discapacidad visual atendidos en dos instituciones de salud de la ciudad de Medellín (departamento de Antioquia/Colombia), con énfasis en la etiología del déficit visual irreversible. Metodología: estudio observacional descriptivo. Estudio macro sobre deficiencias visuales unilaterales y bilaterales en 1 742 registros de historias clínicas para identificar pacientes con baja visión o ceguera. Aplicación de un formato de investigación orientado a validar los pacientes con discapacidad visual y se seleccionaron 107 historias clínicas. Resultados: el 56.6% presenta discapacidad visual tipo baja visión y el 43.4% discapacidad visual tipo ceguera. El déficit visual responsable de la discapacidad visual fue del 39% por causas oftalmológicas, 20% por alteraciones neuro-oftalmológicas y 17% por trastornos neurológicos de cortezas visuales. Además de la agudeza visual, se encontraron otras deficiencias de la función visual: atrofia óptica, alteración electrofisiológica de la conducción visual y encefalomalacia en cortezas visuales. El 82% de los pacientes tiene al menos una comorbilidad no oftalmológica. Conclusiones: es fundamental un adecuado registro de las características biológicas, sociales, psicológicas y de las actividades de rehabilitación de los pacientes con baja visión y ceguera, para entender en forma integral no sólo la discapacidad sino el impacto que produce.

Objective: to characterize the clinical and socio-demographical characteristics of a population of patients with visual impairment attended at two health institutions in Medellín (Antioquia, Colombia), with an emphasis on the etiology of irreversible vision loss. Methodology: Observational, descriptive study of unilateral and bilateral visual impairment in 1 742 medical records to identify patients with low vision or blindness. A research form was used to validate patients with visual impairment, and 107 medical records were selected. Results: 56.6% presented low vision and 43.4% presented blindness. Vision loss was due to ophthalmic causes in 39% of cases, 20% were caused by neuro-ophthalmic alterations and 17% by neurological disorders of the visual cortex. In addition to visual acuity, other visual impairments were found, such as optic atrophy, electrophysiological alteration of the visual pathway, and encephalomalacia in visual cortices. 82% of patients had at least one nonophthalmic comorbidity. Conclusions: Adequate registration of rehabilitation activity, biological, social, and psychological characteristics of patients with low vision and blindness is essential in order to fully understand both the impairment and its impact.

Ademais da agudeza visual, se encontraram outras deficiências da função visual: atrofia óptica, alteração eletrofisiológica da condução visual e encefalomalácia em córtex visual. 82% dos pacientes têm pelo menos uma comorbilidade não oftalmológica. Conclusões: é fundamental um adequado registro das características biológicas, sociais, psicológicas e das atividades de reabilitação dos pacientes com baixa visão e cegueira, para entender em forma integral não só a incapacidade senão o impacto que produz.

RESUMO

El objetivo de la siguiente investigación fue evaluar la calidad de vida y su relación con la cognición a la enfermedad, en pacientes colostomizados con diagnóstico de cáncer colorectal. Para esto se trabajó con 65 pacientes, de ambos géneros, a partir de 6 meses posteriormente del tratamiento médico quirúrgico. Como instrumentos de medida para la calidad de vida se utilizó el SF36 versión española de Alonso y Cols, 1998 y el cuestionario de cognición a la enfermedad ICQ, versión Holandesa de Evers, 2001. Los resultados fueron analizados con el paquete SPSS, encontrándose diferencias significativas entre las medidas españolas del SF 36 y las medidas de nuestra población de pacientes colostomizados, en las dimensiones de función física, rol físico, dolor corporal, función social, rol emocional y salud mental. Con respectoal ICQ los niveles de desesperanza y aceptación a la enfermedad fueron más elevados en nuestras medidas que las muestras originales de pacientes con Artritis reumatoide y Esclerosis múltiple (Evers, 2001).

The objective of the following investigation was evaluate the quality of the life and their relationship with thee illness cognition, in patient colostomizados with diagnostic of cancer colorectal. For this work with 65 patients, of both genders, starting from 6 posterior months of the medical surgical treatment. Like instrument of measuring for the quality of life it was used the SF36 Spanish version of Alonso and Colds, 1998 and the questionnaire of the illness cognition ICQ. Dutch version of Evers and Cols, 2001. The results were analyzed with the SPSS package , being significant differences between the Spanish means of the SF36 and the means in our population of patients colos-tomizados, in the dimensions of physical Function, role physical, cor-poral pain, social function, role emotional and metal health. With respect to the ICQ the levels of helplessness and acceptance to the illness was more high in our means that in the...
