A cluster randomized controlled trial to assess the efficacy of a telehealth-based train-the-trainer mealtime intervention delivered by respite care center volunteers to caregivers of persons with dementia to improve nutritional outcomes and quality of life.

Background: Persons with dementia with mild to moderate cognitive impairment are at risk for developing impairments with activities of daily living such as the ability to feed oneself, that negatively influence health. Lack of caregiver skills related to mealtime planning for persons with dementia and the ability to cope with dysfunctional behaviors are well-documented factors that influence nutritional status outcomes, lead to weight loss, poor quality of life, and impact their ability to remain at home.

Methods: A cluster randomized controlled trial with a parallel mixed methods evaluation processes will be conducted to examine the efficacy of a train-the-trainer program using non-paid volunteers in respite care centers to deliver a telehealth mealtime intervention guided by the theory-based - In this six-month study, dyads of caregivers and persons with mild to moderate dementia receiving respite care services will be randomized to receive either the telehealth intervention or enhanced usual care.

DASH diet lowers blood pressure and lipid-induced oxidative stress in obesity.

Evidence suggests that obesity may raise blood pressure (BP) through oxidative stress-sensitive mechanisms and that the Dietary Approaches to Stop Hypertension combination diet (DASH-CD) may decrease BP by enhancing antioxidant capacity. To address this question, 12 obese patients with high-normal-to-stage 1 hypertension (hypertensives) and 12 lean normotensives were studied on their usual diets and after following the DASH-CD and a low-antioxidant diet in random sequence for 4 weeks each. Acute oxidative stress was induced by a 4-hour infusion of intralipid and heparin.
