Morphological Biomarkers in the Amygdala and Hippocampus of Children and Adults at High Familial Risk for Depression.

Major Depressive Disorder (MDD) is highly familial, and the hippocampus and amygdala are important in the pathophysiology of MDD. Whether morphological markers of risk for familial depression are present in the hippocampus or amygdala is unknown. We imaged the brains of 148 individuals, aged 6 to 54 years, who were members of a three-generation family cohort study and who were at either high or low familial risk for MDD.

State and Trait Rumination Effects on Overt Attention to Reminders of Errors in a Challenging General Knowledge Retrieval Task.

Rumination is a recurrent and repetitive manner of thinking that can be triggered by blockage of personally relevant goals, creating a temporary state of abstract and evaluative self-focus. Particularly when focused on passive "brooding" over one's problems and feelings, however, rumination can increase negative affect, interfere with problem-solving, and, through a negative feedback cycle, become a chronic trait-like style of responding to personal challenges, particularly in women. Given the pervasiveness of rumination and its potential impact on cognitive processes and emotional states, the present study asks how it impacts attention to feedback that either reminds individuals of goal-state discrepancies (reminders of errors) or could help to remediate them (corrective information).

An Evaluation of the Family Informal Caregiver Stroke Self-Management Program.

Background: Caregivers are often unprepared and overwhelmed with the responsibilities of providing care to stroke survivors, which can lead to negative physical and psychological effects.

Purpose: To evaluate the impact of the Family Informal Caregiver Stroke Self-Management (FICSS) program on burden and life changes resulting from providing care among family caregivers of stroke survivors.

Methods: A prospective pre-test and post-test design using quantitative and qualitative data was used to evaluate the program with a convenience sample of 42 caregivers.

Organic Diode Rectifiers Based on a High-Performance Conjugated Polymer for a Near-Field Energy-Harvesting Circuit.

Organic diodes manufactured on a plastic substrate capable of rectifying a high-frequency radio-frequency identification signal (13.56 MHz), with sufficient power to operate an interactive smart tag, are reported. A high-performance conjugated semiconductor (an indacenodithiophene-benzothiadiazole copolymer) is combined with a carefully optimized architecture to satisfy the electrical requirements for an organic-semiconductor-based logic chip.

Does the NRS Capture Changes in Communication during Inpatient Stroke Rehabilitation?

Background: In Ontario, the National Rehabilitation Reporting System (NRS) is mandated for use as a measurement of change for stroke patients after admission to and discharge from rehabilitation. The NRS includes the functional independence measure (FIM) and supplementary measurement items developed by the Canadian Institute for Health Information (CIHI). Uncertainty exists regarding the efficacy of the NRS as the sole measure of outcome for communication in stroke rehabilitation patients.
