OBJECTIVE: Identifying adaptive ways to cope with extreme stress is essential to promoting long-term health. Memory systems are highly sensitive to stress, and combat exposure during war has been shown to have deleterious effects on cognitive processes, such as memory, decades later. No studies have examined coping styles used by combat veterans and associations with later-life cognitive functioning. Defenses are coping mechanisms that manage difficult memories and feelings, with some more closely related to memory processes (e...

In vitro and in vivo studies suggest that the astrocytic adrenergic signalling enhances glycogenolysis which provides energy to be transported to nearby cells and in the form of lactate. This energy source is important for motor and cognitive functioning. While it is suspected that the β2-adrenergic receptor on astrocytes might contribute to this energy balance, it has not yet been shown conclusively in vivo. Inducible astrocyte specific β2-adrenergic receptor knock-out mice were generated by crossing homozygous β2-adrenergic receptor floxed mice (Adrb2flox) and mice with heterozygous tamoxifen-inducible Cre recombinase-expression driven by the astrocyte specific L-glutamate/L-aspartate transporter promoter (GLAST-CreERT2)...

BACKGROUND: Inflammation after cardiopulmonary bypass may contribute to postoperative delirium and cognitive dysfunction. The authors evaluated the effect of high-dose methylprednisolone to suppress inflammation on the incidence of delirium and postoperative quality of recovery after cardiac surgery. METHODS: Five hundred fifty-five adults from three hospitals enrolled in the randomized, double-blind Steroids in Cardiac Surgery trial were randomly allocated to placebo or 250 mg methylprednisolone at induction and 250 mg methylprednisolone before cardiopulmonary bypass...

Symptoms of inattention and hyperactivity frequently co-occur with language difficulties in both clinical and community samples. We explore the specificity and strength of these associations in a heterogeneous sample of 254 children aged 5 to 15 years identified by education and health professionals as having problems with attention, learning and/or memory. Parents/carers rated pragmatic and structural communication skills and behaviour, and children completed standardised assessments of reading, spelling, vocabulary, and phonological awareness...

This study provides an empirical test of two mechanisms (social capital and exposure to air pollution) that are theorized to mediate the effect of neighborhood on health and contribute to racial disparities in health outcomes. To this end, we utilize the Social Capital Benchmark Study, a national survey of individuals nested within communities in the United States, to estimate how multiple dimensions of social capital and exposure to air pollution, explain racial disparities in self-rated health. Our main findings show that when controlling for individual-confounders, and nesting within communities, our indicator of cognitive bridging, generalized trust, decreases the gap in self-rated health between African Americans and Whites by 84%, and the gap between Hispanics and Whites by 54%...

OBJECTIVE: While the importance of traumatic brain injury (TBI) has gained public attention in recent years, relatively little attention has been paid to head injuries among women who have experienced intimate partner violence (IPV). The present study screened for lifetime exposure to mild traumatic brain injuries (mTBI) among a sample of women who experienced recent IPV (median days since target incident = 26). METHOD: Participants included ethnically diverse women whose IPV experiences were reported to law enforcement...

OBJECTIVE: Examine the independent association of sedentary behavior and cognitive function in older adults, as well as whether or not physical activity attenuates this potential association. METHODS: Data from the 1999-2002 National Health and Nutrition Examination Survey were used (N=2,472 adults 60-85 yrs). Sedentary behavior was subjectively assessed and the Digit Symbol Substitution Test (DSST) was employed to assess cognitive function. RESULTS: Among an unadjusted and an adjusted model not accounting for physical activity, only 5+ hrs/day (vs...

A growing percentage of low-income children in the United States come from Spanish-speaking homes and are dual language learners (DLLs). Recent research shows that bilingual children, compared to monolinguals, have enhanced executive functioning (EF), a set of foundational cognitive skills that predict higher social-emotional competence and academic achievement in preschool and beyond. Although this association has been found among children of different backgrounds, no study to date has assessed whether bilingual Latino preschoolers from low-income backgrounds have higher EF than their monolingual peers and their emerging bilingual peers, respectively...

Impaired cognitive empathy is a core social cognitive deficit in schizophrenia associated with negative symptoms and social functioning. Cognitive empathy and negative symptoms have also been linked to medial prefrontal and temporal brain networks. While shared behavioral and neural underpinnings are suspected for cognitive empathy and negative symptoms, research is needed to test these hypotheses. In two studies, we evaluated whether resting-state functional connectivity between data-driven networks, or components (referred to as, inter-component connectivity), predicted cognitive empathy and experiential and expressive negative symptoms in schizophrenia subjects...

: WHAT IS KNOWN ON THE SUBJECT?: Panic disorder patients display various panic-related physical symptoms and catastrophic misinterpretation of bodily sensations, which lower their quality of life by interfering with daily activities. Cognitive behavioural therapy (CBT) is a useful strategy for panic disorder patients to manage symptoms associated with inaccurate cognitive interpretation of situations resulting from the patient's cognitive vulnerability. In South Korea, however, despite the increasing prevalence of panic disorder, CBT is not a common element of nursing care plans for panic disorder patients...

Management of older people on dialysis requires focus on the wider aspects of aging as well as dialysis. Almost all frail and older patients receiving dialysis will default to in-center hemodialysis, although the availability of assisted peritoneal dialysis enables dialysis at home. As with any disease management decision, patients approaching end-stage renal disease need all the appropriate facts about their prognosis, the natural history of their disease without dialysis, and the resulting outcomes and complications of the different dialysis modalities...
