“…Furthermore, statistically significant R-squared values for PSQI and ESS scores for learning and academic performances obtained in the study support the above findings (Table 2). Cognition has been reported to be influenced by insufficient sleep among medical students in the previous literature similar to our findings [39]. This finding lines up with the evidence from the past, stating the positive effect of sleep on memory, learning, acquisition of skills, and knowledge extraction [40,41].…”

The link between sleep and cognitive processes, such as memory and learning, continues to be one of the most intriguing and perplexing theories. Undergraduate medical students in their first year are particularly vulnerable to sleep disturbances. Academic achievement and learning have been linked to sleep patterns, which include not only the quantity and quality of sleep but also the timing of sleep in relation to the natural sleep onsets, or chronotypes. There have been conflicting reports on the outcomes of sleep and relatively fewer researches focused on the impact of chronotypes on learning and academic achievement among medical students. The current study thus sought to determine the chronotypes of medical students, evaluate the quantity and quality of sleep, and determine the impact of these factors on learning and academic performance. MethodsThe study was conducted in the

Type 1 diabetes (T1D) is a chronic condition characterized by glucose fluctuations. Laboratory studies suggest that cognition is reduced when glucose is very low (hypoglycemia) and very high (hyperglycemia). Until recently, technological limitations prevented researchers from understanding how naturally-occurring glucose fluctuations impact cognitive fluctuations. This study leveraged advances in continuous glucose monitoring (CGM) and cognitive ecological momentary assessment (EMA) to characterize dynamic, within-person associations between glucose and cognition in naturalistic environments. Using CGM and EMA, we obtained intensive longitudinal measurements of glucose and cognition (processing speed, sustained attention) in 200 adults with T1D. First, we used hierarchical Bayesian modeling to estimate dynamic, within-person associations between glucose and cognition. Consistent with laboratory studies, we hypothesized that cognitive performance would be reduced at low and high glucose, reflecting cognitive vulnerability to glucose fluctuations. Second, we used data-driven lasso regression to identify clinical characteristics that predicted individual differences in cognitive vulnerability to glucose fluctuations. Large glucose fluctuations were associated with slower and less accurate processing speed, although slight glucose elevations (relative to person-level means) were associated with faster processing speed. Glucose fluctuations were not related to sustained attention. Seven clinical characteristics predicted individual differences in cognitive vulnerability to glucose fluctuations: age, time in hypoglycemia, lifetime severe hypoglycemic events, microvascular complications, glucose variability, fatigue, and neck circumference. Results establish the impact of glucose on processing speed in naturalistic environments, suggest that minimizing glucose fluctuations is important for optimizing processing speed, and identify several clinical characteristics that may exacerbate cognitive vulnerability to glucose fluctuations.

Introducción: el desarrollo de las funciones ejecutivas, como actividades cognitivas de orden superior, son fundamentales en el proceso académico de los estudiantes, sin embargo, los resultados sobre su contribución a la formación médica son contradictorios sobre el efecto a corto y largo plazo. Objetivos: caracterizar un grupo de funciones ejecutivas y el desempeño académico de los estudiantes de Medicina que cursan el segundo, quinto y décimo semestres en la Corporación Universitaria Remington. Métodos: investigación descriptiva de corte con muestra de 119 estudiantes del segundo, quinto y décimo semestres en 2021–2 en la Corporación Universitaria Remington. Se caracterizó un conjunto de funciones ejecutivas a partir del rendimiento académico, pruebas neurocognitivas y variables sociodemográficas. Resultados: se evidenció que los estudiantes bilingües presentan mejores puntajes en memoria de trabajo, flexibilidad cognitiva y control inhibitorio. En cuanto al semestre cursado, no se obtuvo una correlación significativa, sin embargo, se observó que a medida que se avanza en los semestres los puntajes en memoria de trabajo y control inhibitorio tienden a mejorar, mientras que en flexibilidad cognitiva los puntajes de errores perseverativos tienden a disminuir. Con respecto a los hábitos de estudio, se comprueba que una mayor cantidad de años estudiados, así como una mayor inversión de tiempo en estudio extraclase, mejoran los puntajes del control inhibitorio. Conclusiones: se evidenció que la variable bilingüismo se relaciona con mejores puntajes en las funciones ejecutivas. Asimismo, la cantidad de años estudiados y el tiempo de estudio extraclase mostraron una correlación con el control inhibitorio.
