Differences in Medial Temporal Network Intrinsic Connectivity After a Single Bout of Exercise Relate to Fitness, Memory, and Affect.

Introduction: Chronic exercise has been linked to structural and functional changes in the hippocampus and surrounding areas. However, less is known about how a single session of exercise can induce immediate effects that may contribute to these longterm changes.

Objective/methods: Resting-state fMRI was used to investigate changes in brain networks 19 minutes after a 20-minute bout of vigorous-intensity acute exercise.

Relationship Between Dietary Patterns and Blood Pressure During Adolescence: A Longitudinal Analysis From Dados Study.

Background: Previous research in adults has suggested that healthy dietary patterns could be an effective strategy for blood pressure (BP) control. However, during adolescence, the scientific literature examining this relationship is scarce and controversial since inverse and null associations have been reported. Thus, the aim of our study was to analyze the relationship between the level of adherence to the Mediterranean diet (MD) and consumption of fresh fruits and vegetables at baseline with changes in BP over a two-year period during adolescence.

Physical activity and hippocampal volume in young adults.

Evidence from previous studies suggests that physical activity (PA) may contribute to functional and structural changes in the hippocampus throughout the lifespan. However, there is limited evidence available regarding the young adult population. Additionally, the personality traits that may influence this association remain unclear.

Mediating role of physical fitness on the association between diet and health-related quality of life in adolescents.

Objective: The aim of this study was to analyse whether the association between adherence to the Mediterranean diet and health-related quality of life (HRQoL) is mediated by physical fitness components (i.e., cardiorespiratory fitness, lower-limb strength, upper-limb strength and motor competence) in adolescents.

[Brote de la COVID-19 en una residencia en ancianos correctamente vacunados. Influencia de la inmunidad híbrida en la carga viral, el riesgo de infección y el riesgo de progresión de la enfermedad].

Objective: This study addressed a COVID-19 outbreak in a nursing home, where the residents were vaccinated with two doses of Comirnaty® and thirty of them had previously had the infection. Outbreaks in closed communities are opportunities to study the entire clinical spectrum of the disease and, as in this case, the effect of hybrid immunity on transmission, infection progression and viral load.

Methods: A descriptive and retrospective cohort study in the resident population was carried out.
