Chronically homeless persons' participation in an advance directive intervention: A cohort study.

Background: Chronically homeless individuals have high rates of hospitalization and death, and they may benefit from the completion of advance directives.

Aim: To determine the rate of advance directive completion using a counselor-guided intervention, identify characteristics associated with advance directive completion, and describe end-of-life care preferences in a group of chronically homeless individuals.

Design: Participants completed a survey and were offered an opportunity to complete an advance directive with a trained counselor.

"My body's a 50 year-old but my brain is definitely an 85 year-old": exploring the experiences of men ageing with HIV-associated neurocognitive challenges.

Introduction: Research investigating HIV, neurocognition and ageing is well developed using neuropsychometric or other quantitative approaches; however, little is known about individuals' subjective experiences. The purpose of this article is to explore the experiences of men aged 50 and older who self-identify as having HIV-associated neurocognitive challenges. In particular, this study uses the Episodic Disability Framework (EDF) to explore participants' perceptions regarding: 1) symptoms/impairments, difficulties with day-to-day activities, challenges with social inclusion and uncertainty; 2) ageing as related to their HIV-associated neurocognitive challenges, and 3) the episodic nature of their HIV-associated neurocognitive challenges.

Modulation of the effects of methylmercury on rat neurodevelopment by co-exposure with Labrador Tea (Rhododendron tomentosum ssp. subarcticum).

Seafood is an important source of nutrients for many populations worldwide. Unfortunately the contamination of seafood with methylmercury (MeHg) has raised health concerns, particularly for developing infants. The modification of MeHg toxicity by nutrients, including antioxidants, has been reported in both epidemiological and animal exposure studies.
