Complexity Analysis of the Default Mode Network Using Resting-State fMRI in Down Syndrome: Relationships Highlighted by a Neuropsychological Assessment.

Background: Studies on complexity indicators in the field of functional connectivity derived from resting-state fMRI (rs-fMRI) in Down syndrome (DS) samples and their possible relationship with cognitive functioning variables are rare. We analyze how some complexity indicators estimated in the subareas that constitute the default mode network (DMN) might be predictors of the neuropsychological outcomes evaluating Intelligence Quotient (IQ) and cognitive performance in persons with DS.

Methods: Twenty-two DS people were assessed with the Kaufman Brief Test of Intelligence (KBIT) and Frontal Assessment Battery (FAB) tests, and fMRI signals were recorded in a resting state over a six-minute period.

Resting-state default mode network connectivity in young individuals with Down syndrome.

Background: Down syndrome (DS) is a chromosomal disorder that causes intellectual disability. Few studies have been conducted on functional connectivity using resting-state fMRI (functional magnetic resonance imaging) signals or more specifically, on the relevant structure and density of the default mode network (DMN). Although data on this issue have been reported in adult DS individuals (age: >45 years), the DMN properties in young DS individuals have not been studied.

Relationship between sense of coherence and diabetes mellitus: a systematic review.

The aim was to synthesize the best scientific evidence on the effect of sense of coherence in disease development, treatment, and biomedical metabolic control indicators, as well as the complications involved for people at risk of developing diabetes and for diabetics. The systematic review method was implemented. Search and selection efforts of two independent reviewers on Scopus, Web of Science, PubMed, Ebsco, Science Direct, and manuals databases, available until 2017, in Spanish and English, of the population aged 18 and over.

[Cultural dimensions of dengue that help or hinder its prevention in Mexico].

Objective: To describe the cultural dimensions that might help or hinder dengue prevention in two Mexican localities having different experiences related to this disease.

Methods: A cognitive-cultural anthropological study was conducted involving the participation of 160 adults selected through purposeful sampling. The techniques of free lists and pile-sorting were used for investigating terms associated with the concept "dengue.
