Functional brain hubs are related to age: A primer study with rs-fMRI.

Background/objective: Research on the ontogenetic development of brain networks using resting state has shown to be useful for understanding age-associated changes in brain connectivity. This work aimed to analyze the relationship between brain connectivity, age and intelligence.

Methods: A sample of 26 children and adolescents between 6 and 18 years of both sexes underwent a resting-state functional magnetic resonance imaging study.

A comprehensive systematic review of fMRI studies on brain connectivity in healthy children and adolescents: Current insights and future directions.

This systematic review considered evidence of children's and adolescents' typical brain connectivity development studied through resting-state functional magnetic resonance imaging (rs-fMRI). With aim of understanding the state of the art, what has been researched thus far and what remains unknown, this paper reviews 58 studies from 2013 to 2023. Considering the results, rs-fMRI stands out as an appropriate technique for studying language and attention within cognitive domains, and personality traits such as impulsivity and empathy.

Reduced default mode network effective connectivity in healthy aging is modulated by years of education.

Aging is a major risk factor for neurodegenerative diseases like dementia and Alzheimer's disease. Even in non-pathological aging, decline in cognitive functioning is observed in the majority of the elderly population, necessitating the importance of studying the processes involved in healthy aging in order to identify brain biomarkers that promote the conservation of functioning. The default mode network (DMN) has been of special interest to aging research due to its vulnerability to atrophy and functional decline over the course of aging.

Burden and anticipatory grief in caregivers of family members with Alzheimer's disease and other dementias.

Objectives: This study aimed to analyze the different factors that intervene in the task of caring for relatives of people with Alzheimer's and other dementias. A first objective focused on assessing the relation between burden and anticipatory grief, considering the possibility of social support and the risk of psychopathology. A second objective aimed to examine whether caregiver burden modulates the relationships between anticipatory grief and psychopathology.

Designing and psychometric properties of the hospitalized patients' spiritual needs questionnaire (HPSNQ) in the medical-surgical hospital setting.

Background: The evaluation of spiritual requirements in patients can facilitate the delivery of spiritual care as an essential element of holistic healthcare. The objective of this research was to develop and evaluate the psychometric properties of a questionnaire on patients' spiritual needs in medical-surgical hospital settings.

Methods: This research utilized an exploratory sequential design, involving the creation of a pool of items through both inductive and deductive methods.
