Accelerated development of cardiovascular risk factors mediates risk for major adverse cardiovascular events in posttraumatic stress disorder.

Background: Individuals with posttraumatic stress disorder (PTSD) have high rates of cardiovascular disease (CVD) and increased cardiometabolic CVD risk factors (CVDRFs, e.g., hypertension, hyperlipidemia, or diabetes mellitus).

Optical Taxonomic Signal and the Diagnosis of Alzheimer's Disease.

We previously demonstrated that near-infrared spectroscopy in vivo presents spectral features at 895 and 861 nm that accurately classify Alzheimer's disease, mild cognitive impairment, and age-matched control subjects. Our purpose here is to associate the 895 nm signal with [Formula: see text]-amyloid. We applied our feature selection technique to subjects with and without leptomeningeal amyloid.

Intraspecific Variation in Parental Care May Reflect Variation in Parental Quality.

The existence of life-history trade-offs is a fundamental assumption of evolutionary biology and behavioural ecology, yet empirical studies have found mixed evidence for this. Such trade-offs are expected when individuals vary in how they allocate their limited resource budgets between different life-history functions (variation in resource allocation), but they may be masked when individuals vary in how many resources they have acquired that they can later allocate to life-history functions (variation in resource acquisition). We currently lack studies on the extent to which individual differences in behaviour reflect variation between individuals in resource acquisition and resource allocation.

Nonpharmacologic Management of Hypertension in Older Adults.

Hypertension is ubiquitous among older adults and leads to major adverse cardiovascular events. Nonpharmacologic lifestyle interventions represent important preventive and adjunct strategies in the treatment of hypertension and have benefits beyond cardiovascular disease in this population characterized by a high prevalence of frailty and comorbid conditions. In this review, the authors examine nonpharmacologic interventions with the strongest evidence to prevent cardiovascular disease with an emphasis on the older adults.
