Two Attentional Processes Subserving Working Memory Differentiate Gifted and Mainstream Students.

Two working memory (WM) measures were contrasted, to clarify the nature of advantages in gifted children's cognitive processing. It was predicted that cognitively gifted children would excel in WM tasks taxing mental attention (i.e.

Targeting the Dietary Na:K Ratio-Considerations for Design of an Intervention Study to Impact Blood Pressure.

Despite medical, dietary, and lifestyle recommendations and drug advancements, hypertension persists as among the most prevalent noncommunicable diseases in the US population, and control remains elusive. Uncontrolled hypertension may increase the risk of serious illness from various other health challenges, including cardiovascular and renal responses. Adoption of a healthy diet is a consistent core element of lifestyle modifications that are recommended for mitigation of hypertension.

Machine learning can predict disease manifestations and outcomes in lymphangioleiomyomatosis.

Background: Lymphangioleiomyomatosis (LAM) is a rare multisystem disease with variable clinical manifestations and differing rates of progression that make management decisions and giving prognostic advice difficult. We used machine learning to identify clusters of associated features which could be used to stratify patients and predict outcomes in individuals.

Patients And Methods: Using unsupervised machine learning we generated patient clusters using data from 173 women with LAM from the UK and 186 replication subjects from the US National Heart, Lung, and Blood Institute (NHLBI) LAM registry.

The vitamin D binding protein axis modifies disease severity in lymphangioleiomyomatosis.

Lymphangioleiomyomatosis (LAM) is a rare disease of women. Decline in lung function is variable, making appropriate targeting of therapy difficult. We used unbiased serum proteomics to identify markers associated with outcome in LAM.

Visualizing complex processes using a cognitive-mapping tool to support the learning of clinical reasoning.

Background: Practical experience with clinical cases has played an important role in supporting the learning of clinical reasoning. However, learning through practical experience involves complex processes difficult to be captured by students. This study aimed to examine the effects of a computer-based cognitive-mapping approach that helps students to externalize the reasoning process and the knowledge underlying the reasoning process when they work with clinical cases.

The mental-attention Tai Chi effect with older adults.

Background: Tai Chi practice has some fitness, wellness, and general cognitive effects in older adults. However, benefits of Tai Chi on specific mental-attentional executive processes have not been investigated previously. We studied older Canadian adults of Chinese and non-Chinese origin and from low socioeconomic areas.

Faculty-Mentor-in-Rez: The development of a new faculty-in-residence model.

Faculty-in-residence programs have long been touted as a successful way to provide for both intentional and casual out-of-the-classroom interactions between students and faculty. Despite research on the benefits to students and to faculty of such programs, academic commitments and lack of clarity around the role of live-in faculty has made recruiting of faculty a challenge. This case study provides an account of how McGill University, a publicly-funded, research-intensive university in Montreal, Canada, undertook the development and implementation of a new faculty-in-residence model that honored the long history of faculty living in McGill's residences, provided structured opportunities for faculty-student engagement, and reflected McGill's unique residence culture.

Improving the learning of clinical reasoning through computer-based cognitive representation.

Objective: Clinical reasoning is usually taught using a problem-solving approach, which is widely adopted in medical education. However, learning through problem solving is difficult as a result of the contextualization and dynamic aspects of actual problems. Moreover, knowledge acquired from problem-solving practice tends to be inert and fragmented.

Association of depression with accelerated cognitive decline among patients with type 2 diabetes in the ACCORD-MIND trial.

Importance: Depression has been identified as a risk factor for dementia among patients with type 2 diabetes mellitus but the cognitive domains and patient groups most affected have not been identified.

Objective: To determine whether comorbid depression in patients with type 2 diabetes accelerates cognitive decline.

Design: A 40-month cohort study of participants in the Action to Control Cardiovascular Risk in Diabetes-Memory in Diabetes (ACCORD-MIND) trial.

A balancing act of the brain: activations and deactivations driven by cognitive load.

The majority of neuroimaging studies focus on brain activity during performance of cognitive tasks; however, some studies focus on brain areas that activate in the absence of a task. Despite the surge of research comparing these contrasted areas of brain function, their interrelation is not well understood. We systematically manipulated cognitive load in a working memory task to examine concurrently the relation between activity elicited by the task versus activity during control conditions.

Executive functions underlying multiplicative reasoning: problem type matters.

We investigated the extent to which inhibition, updating, shifting, and mental-attentional capacity (M-capacity) contribute to children's ability to solve multiplication word problems. A total of 155 children in Grades 3-6 (8- to 13-year-olds) completed a set of multiplication word problems at two levels of difficulty: one-step and multiple-step problems. They also received a reading comprehension test and a battery of inhibition, updating, shifting, and M-capacity measures.

The Action to Control Cardiovascular Risk in Diabetes Memory in Diabetes Study (ACCORD-MIND): rationale, design, and methods.

Type 2 diabetes mellitus and cognitive impairment are 2 of the most common chronic conditions found in persons aged > or = 60 years. Clinical studies have shown a greater prevalence of global cognitive impairment, incidence of cognitive decline, and incidence of Alzheimer disease in patients with type 2 diabetes. To date, there have been no randomized trials of the effects of long-term glycemic control on cognitive function and structural brain changes in patients with type 2 diabetes.

Processing limitations in children with specific language impairment: the role of executive function.

Research suggests that children with specific language impairment (SLI) have processing limitations; however, the mechanisms involved have not been well defined or investigated in a theory-guided manner. The theory of constructive operators was used as a framework to explore processes underlying limited processing capacity in children with SLI. Mental attentional capacity, mental attentional interruption, and 2 specific executive functions (shifting and updating) were examined in 45 children with SLI and 45 children with normally developing language, aged 7 to 12 years.

Development of mental attention in gifted and mainstream children: the role of mental capacity, inhibition, and speed of processing.

The study examined performance of 6- to 11-year-old children, from gifted and mainstream academic programs, on measures of mental-attentional capacity, cognitive inhibition, and speed of processing. In comparison with mainstream peers, gifted children scored higher on measures of mental-attentional capacity, responded more quickly on speeded tasks of varying complexity, and were better able to resist interference in tasks requiring effortful inhibition. There was no group difference on a task requiring automatic inhibition.

The violent matrix: a study of structural, interpersonal, and intrapersonal violence among a sample of poor women.

One goal of this paper is to present an integrated tripartite model of violence, with a focus on structural violence within an oppression paradigm. Using qualitative and quantitative data from 27 women (70% African American and 30% European American) who participated in a national substance abuse treatment demonstration program, we describe a model of violence in which structural violence is presented within a transactional relationship with interpersonal, and intrapersonal violence. We suggest that the effects of structural, interpersonal, and intrapersonal violence are magnified when race and poverty are considered.
