No relations between executive functions and dimensional models of psychopathology or is time the missing link?

Impaired executive functions (EF) have been found within various mental disorders (e.g., attention deficit hyperactivity disorder, autism spectrum disorder, schizophrenia spectrum disorders) as described in DSM-5.

Poor nutritional status, risk of sarcopenia and nutrition related complaints are prevalent in COVID-19 patients during and after hospital admission.

Background And Aims: Patients with COVID-19 infection presents with a broad clinical spectrum of symptoms and complications. As a consequence nutritional requirements are not met, resulting in weight- and muscle loss, and malnutrition. The aim of the present study is to delineate nutritional complaints, the (course of the) nutritional status and risk of sarcopenia of COVID-19 patients, during hospitalisation and after discharge.

Predictive Value of Traditional Measures of Executive Function on Broad Abilities of the Cattell-Horn-Carroll Theory of Cognitive Abilities.

The neuropsychological construct of executive functions (EFs), and the psychometric Cattell-Horn-Carroll (CHC) theory of cognitive abilities are both approaches that attempt to describe cognitive functioning. The coherence between EF and CHC abilities has been mainly studied using factor-analytical techniques. Through multivariate regression analysis, the current study now assesses the integration of these latent constructs in clinical assessment.

Representation of the Cattell-Horn-Carroll Theory of Cognitive Abilities in the Factor Structure of the Dutch-Language Version of the WAIS-IV.

The Cattell-Horn-Carroll (CHC) theory of cognitive abilities has been guiding in the revision of the Wechsler Adult Intelligence Scale-Fourth edition (WAIS-IV). Especially the measurement of fluid reasoning (Gf) is improved. A total of five CHC abilities are included in the WAIS-IV subtests.

Effect of Early Individualized Dietary Counseling on Weight Loss, Complications, and Length of Hospital Stay in Patients With Head and Neck Cancer: A Comparative Study.

Patients with head and neck cancer (HNC) are at risk for undernutrition. Dietary counseling during treatment has positive effects on nutritional status and quality of life, however, the effects of dietary counseling started before initiation of treatment are currently unknown. Therefore we assessed the effect of early individualized dietary counseling (DC) on weight loss, major complications, and length of hospital stay (LOS) in patients with HNC.

Fluid intelligence and executive functioning more alike than different?

Objective: Fluid intelligence (Gf) has been related to executive functioning (EF) in previous studies, and it is also known to be correlated with crystallized intelligence (Gc). The present study includes representative measures of Gf, Gc, and EF frequently used in clinical practice to examine this Gf-EF relation. It is hypothesised that the Gf-EF relation is higher than the Gc-EF relation, and that working memory in particular (as a measure of EF) shows a high contribution to this relation.

Decline of executive function in a clinical population: age, psychopathology, and test performance on the Cambridge Neuropsychological Test Automated Battery (CANTAB).

This study presents a cross-sectional examination of the age-related executive changes in a sample of adults with a history of psychiatric illness using the Cambridge Neuropsychological Test Automated Battery. A total of 406 patients, aged 18 to 72 years old, completed executive function tests of working memory, strategic planning, and set shifting. Using current Diagnostic and Statistical Manual for Mental Disorders-Fourth Edition criteria, patients were diagnosed with: (a) affective disorders (N = 153), (b) substance-related disorders (N = 112), (c) personality disorders (N = 82), or (d) pervasive developmental disorders (N = 59).
