Beta-adrenergic blockade and voice: a double-blind, placebo-controlled trial.

This study investigated the effects of laboratory-induced stress and beta-adrenergic blockade on acoustic and aerodynamic voice measures. In a double-blind, placebo-controlled trial, 12 participants, six males and six females, underwent cold pressor-induced sympathetic activation followed by placebo or treatment with 40 mg propranolol. Aerodynamic and acoustic parameters of voice were collected at baseline, during cold pressor and after treatment with propranolol or placebo.

Nutritional risk among Oklahoma congregate meal participants.

Objective: To determine if there were differences by demographic variables in response rates to Nutrition Screening Initiative (NSI) Checklist statements reported by over 50% of Oklahoma Older Americans Act Nutrition Program (OAANP) congregate meal participants categorized at high nutritional risk based on cumulative NSI Checklist scores.

Design: This study evaluated Oklahoma State Unit on Aging statewide archival demographic and NSI Checklist data from 8892 OAANP congregate participants.

Analysis: Data were analyzed using chi-square analyses.

Factors associated with Oklahoma Older Americans Act Nutrition Program participants ability to shop, cook, and feed themselves.

Oklahoma Older Americans Act Nutrition Program participants' (n = 859) ability to shop, cook, and feed themselves was evaluated using factor analysis and logistic regression. Congregate participants who reported they were not able to shop, cook, and feed themselves had significantly lower "mobility," "financial management," and "financial security" factor scores; home-delivered participants had significantly lower "mobility," "living arrangement" and "financial security," and higher "social interaction" factor scores. For congregate meal participants the factors "mobility" and "financial management" and for home-delivered meal participants, the factors "mobility" and "social interaction" were significantly associated with reported ability to shop, cook, and feed themselves.
