Variants in APOE and PSEN1 (encoding apolipoprotein E and presenilin 1, respectively) alter the risk of Alzheimer's disease. We previously reported a delay of cognitive impairment in a person with autosomal dominant Alzheimer's disease caused by the PSEN1 E280A variant who also had two copies of the apolipoprotein E3 Christchurch variant (APOE3 Ch). Heterozygosity for the APOE3 Ch variant may influence the age at which the onset of cognitive impairment occurs. We assessed this hypothesis in a population in which the PSEN1 E280A variant is prevalent. We analyzed data from 27 participants with one copy of the APOE3 Ch variant among 1077 carriers of the PSEN1 E280A variant in a kindred from Antioquia, Colombia, to estimate the age at the onset of cognitive impairment and dementia in this group as compared with persons without the APOE3 Ch variant. Two participants underwent brain imaging, and autopsy was performed in four participants. Among carriers of PSEN1 E280A who were heterozygous for the APOE3 Ch variant, the median age at the onset of cognitive impairment was 52 years (95% confidence interval [CI], 51 to 58), in contrast to a matched group of PSEN1 E280A carriers without the APOE3 Ch variant, among whom the median age at the onset was 47 years (95% CI, 47 to 49). In two participants with the APOE3 Ch and PSEN1 E280A variants who underwent brain imaging, 18F-fluorodeoxyglucose positron-emission tomographic (PET) imaging showed relatively preserved metabolic activity in areas typically involved in Alzheimer's disease. In one of these participants, who underwent 18F-flortaucipir PET imaging, tau findings were limited as compared with persons with PSEN1 E280A in whom cognitive impairment occurred at the typical age in this kindred. Four studies of autopsy material obtained from persons with the APOE3 Ch and PSEN1 E280A variants showed fewer vascular amyloid pathologic features than were seen in material obtained from persons who had the PSEN1 E280A variant but not the APOE3 Ch variant. Clinical data supported a delayed onset of cognitive impairment in persons who were heterozygous for the APOE3 Ch variant in a kindred with a high prevalence of autosomal dominant Alzheimer's disease.

Autosomal dominant Alzheimer’s disease (ADAD) is genetically determined, but variability in age of symptom onset suggests additional factors may influence cognitive trajectories. Although apolipoprotein E (APOE) genotype and educational attainment both influence dementia onset in sporadic AD, evidence for these effects in ADAD is limited. To investigate the effects ofAPOEand educational attainment on age-related cognitive trajectories in ADAD, we analyzed data from 675 Presenilin-1 E280A mutation carriers and 594 non-carriers. Here we show that age-related cognitive decline is accelerated in ADAD mutation carriers who also have anAPOEe4 allele compared to those who do not and delayed in mutation carriers who also have anAPOEe2 allele compared to those who do not. Educational attainment is protective and moderates the effect ofAPOEon cognition. Despite ADAD mutation carriers being genetically determined to develop dementia, age-related cognitive decline may be influenced by other genetic and environmental factors.

La pandemia de COVID-19 ha llevado a la implementación del aislamiento preventivo como medida de salud pública y con esto, se presentan nuevos retos para las instituciones de educación superior y en especial para carreras con alto contenido presencial. Se realizó una revisión de la literatura en Pubmed en conjunto con textos de referencia en educación virtual, educación médica, opiniones de expertos y artículos derivados de estos por método bola de nieve. Las ventajas de la educación médica virtual hacen alusión, en su mayoría, a la flexibilidad en tiempo, espacios, oportunidades y recursos desde un enfoque individualizado. Las desventajas, por su parte, dependen de la falta de preparación en infraestructura, así como por parte de docentes y estudiantes para las nuevas modalidades. Las recomendaciones se basan en un cambio de estrategia en el que el estudiante pueda abordar los contenidos de forma amigable y resumida previo a las clases en-vivo y que estas últimas tengan un enfoque dirigido a la complementación y resolución de dudas. Se presentan recomendaciones para los docentes que actualmente dictan sus contenidos de manera virtual para favorecer el aprendizaje y cumplimiento de objetivos. Se incluye un anexo con herramientas para el desarrollo de clases y otros contenidos útiles para el estudio de temas en distintas áreas.

Introduction: Gait speed (GS) is a predictor of negative outcomes in older adults and in those in risk to develop cognitive impairment; as such, it has been associated with dementia. Studies in Latin-American older adults showing this association are scarce. This study aimed to evaluate the relationship between GS and dementia in a representative sample of Colombian older adults. Methods: This study is a secondary analysis from the Survey on Health, Well-Being, and Aging, SABE (from initials in Spanish: Salud, Bienestar & Envejecimiento) Colombia’s survey conducted in 2015 with a sample of 23,694 elderly adults aged 60 years or older. Results: A total of 19,470 participants from the SABE Colombia survey were available for analysis. The multivariate analysis shows that dementia was associated with slow GS (PR 2.39; CI 1.91–3.01) independently to the other variables (p < 0.001). Similarly, GS as a continuous variable shows a statistically significant association with dementia in the adjusted analysis (OR 0.06; CI 0.04–0.09; p < 0.001). Conclusion: Dementia was associated with slow GS. This finding provides evidence to include GS as a complementary parameter in the assessment of Colombian elderly adults.

Introducción. Enfermedades como la diabetes mellitus y la hipertensión arterial son cada vez más frecuentes a nivel mundial con importantes costos sociales asociados. Objetivo. Evaluar la prevalencia de hipertensión y diabetes en los trabajadores de la plaza de mercado de un municipio de Antioquia, Colombia y los factores de riesgo asociados. Metodología. Se llevó a cabo un estudio observacional de tipo transversal analítico en un censo de 194 trabajadores de los cuales 152 tuvieron evaluación médico-laboral y encuesta de datos sociodemográficos y laborales. Se hizo una estandarización previa de los evaluadores con control de calidad del dato y análisis univariado y bivariado de los datos con IC 95%. Resultados. El 57% era mujer, 73,4% ganaba menos de un salario mínimo mensual legal vigente, 65,8% laboraba entre 9 y 12 horas y 11,9% entre 13 y 18 horas al día. El 62,4% no realizaba actividad física y 67,0% prefería los alimentos fritos. Un 20,9% tenía hipertensión arterial y se asoció con el estado civil, edad, antigüedad en el oficio, presión sistólica al momento de la evaluación, antecedente familiar y sexo. Un 9,2% tenía diabetes mellitus y esto se asoció con el estado civil, edad y presión sistólica al momento de la evaluación. Conclusiones. Se encuentra una población trabajadora informal con alta carga de enfermedad y de factores de riesgo que evidencian la necesidad de políticas públicas y programas enfocados específicamente en sus riesgos y estilos de vida.
