This study evaluated the effectiveness of a 12-week psychoeducational group therapy program in improving mood and glycemic control in adults with diabetes and visual impairments. The participants made statistically significant gains in glycemic control, and there was a significant positive relationship between control and improvement in depression, but greater knowledge of diabetes self-care did not correlate with improved glycemic control.

Significant plasma elevations of the powerful vasoconstrictor angiotensin II (AII) were measured in rats following exposure to either 100-dB or 20-dB SPL white noise in three environmental temperatures (5 degrees 21 degrees, and 38 degrees C). Loud noise exposure in the normal temperature condition (21 degrees C) and both temperature extremes with soft noise exposure resulted in plasma AII elevations. The two extreme temperatures combined with loud noise exposure resulted in plasma AII concentrations not different from the levels observed following 20-dB noise at normal temperature. These results indicate that separately administered noise and temperature extremes stimulate the production of AII and thus vasoconstriction. Simultaneous exposure to multiple stressors including noise and temperature extremes may result in severely elevated plasma catecholamines and reduce renal responsiveness to beta-adrenergic stimulation thus reducing plasma AII levels.

Plasma concentrations of the vasoconstrictor Angiotensin II (AII) were measured in male human subjects before and after either rest or exposure to 100-dB white noise. Plasma AII concentrations decreased for subjects in the control (no noise) condition but remained high in the noise condition. In the noise exposure condition both the pre- and post-exposure AII concentrations were negatively but nonsignificantly correlated with TTS. The cardiovascular effects of noise appear to be mediated in part by AII.
