Predictive associations of executive functions and oppositional defiant problems and obsessive-compulsive problems in preschoolers.

Oppositional defiant problems (ODP) and obsessive-compulsive problems (OCP) may co-occur in children, though the way they interact is not known. The aim of the study was to examine longitudinal associations between executive functions at age 3 and ODP, ODP dimensions, and OCP at age 6. The sample consisted of 622 preschoolers (50% were boys) from the general population.

Surgical Treatment of Ischial Ulcers Associated with Deposition of β2-Microglobulin in Two Cases of Dialysis-related Amyloidosis.

The accumulation of β2-microglobulin due to long-term hemodialysis is known as dialysis-related amyloidosis, a rare phenomenon that manifests as a subcutaneous mass. Subcutaneous β2-microglobulin amyloidomas are predominantly located on the buttocks. Owing to the load-bearing properties of this location and proximity to the anus, amyloidomas on the buttocks may be prone to pressure ulcers and infection.

Describing Callous Unemotional Traits and Stressful Life Event Trajectories: Differences on Risk Factors and Mental Health Outcomes from the Age of 3 to 10.

Callous Unemotional (CU) traits are associated with different environmental risk factors, such as negative stressful life events (SLE). The most common studied SLE associated with CU trait has been childhood maltreatment, but less is known about how other SLE impact the development of CU traits. Therefore, this work examines risk factors, personal factors (executive functioning), and mental health outcomes associated with the trajectories of Callous Unemotional (CU) traits and Stressful Life Events (SLE) in a community sample of children.

Age and sex-specific cutoff scores for the teacher-report inventory of callous-unemotional traits on children.

This longitudinal study aims to provide meaningful cutoff scores for total score of the teacher-rated Inventory of Callous-Unemotional Traits (ICU) from the preschool age until early adolescence, separately by age and sex. The ICU cutoff scores were determined by using low/high trajectories of oppositional defiant problems (ODP) and conduct problems in a Spanish community sample of 620 children that were followed up between the ages of 3 and 13. Receiver operating characteristic (ROC) curves with the two trajectories as criteria and ICU total score at each age as a predictor were estimated by sex separately, and the area under the ROC curve (AUC) was obtained.

Reciprocal relations between dimensions of Oppositional defiant problems and callous-unemotional traits.

Although irritability, headstrong/defiant behavior, and callous-unemotional traits (CU traits) often co-occur, the prospective associations between them are not well known. A general population sample of 622 children was followed up yearly from ages 3 to 12 years and assessed using dimensional measures of irritability, headstrong/defiant, and CU traits with teacher provided information. A random intercept cross-lagged panel model, accounting for all unmeasured time-invariant confounding using the children as their own controls, revealed cross-lagged reciprocal associations between increased headstrong/defiant and increased CU traits at all ages and a unidirectional association from headstrong/defiant to irritability.
