[The ward atmosphere and satisfaction in four psychogeriatric wards]

BACKGROUND

We wanted to investigate the treatment milieu in two psychogeriatric hospitals by use of the Ward Atmosphere Scale (WAS), a self-report questionnaire that has been used in studies of the treatment climate in several psychiatric wards.

MATERIAL AND METHODS

22 patients and 54 staff members in four psychogeriatric wards rated the WAS. The staff's perception of the working environment was also examined (the Working Environment Scale, WES-10).

RESULTS

Both patients and staff had higher scores for "order and organization" and lower scores for "anger and aggressive behaviour" than mean scores of the Norwegian normative sample of wards (mainly for patients with psychosis). Three wards obtained higher patient scores for "support" and three obtained lower ones for "staff control". The psychogeriatric patients seemed to be more satisfied with the wards in general and with the staff, whereas the staff's satisfaction and evaluation of the working environment was similar to that of the Norwegian normative sample.

INTERPRETATION

The common trend of the four wards, convincingly shows that the psychogeriatric ward atmosphere differs from that of the wards mainly for psychotic patients. The WAS seemed to be suitable to describe this environment.

Doxazosin treatment and peroxidation of low-density lipoprotein among male hypertensive subjects: in vitro and ex vivo studies

Doxazosin is an antihypertensive drug that gives rise to 6- and 7-hydroxydoxazosin during hepatic metabolism. The structures of the hydroxymetabolites suggest that they may possess antioxidative properties. The aim of the present study was to examine whether doxazosin and 6- and 7-hydroxydoxazosin were able to scavenge free radicals and whether these compounds might protect low-density lipoprotein (LDL) against in vitro and ex vivo oxidation. Both 6- and 7-hydroxydoxazosin showed radical scavenging capacity as assessed by measuring scavenging of 1,1-diphenyl-2-picrylhydrazyl radicals. In vitro incubation with 10 microM 6- and 7-hydroxydoxazosin significantly reduced human mononuclear cell-mediated oxidation of LDL, measured as the formation of lipid peroxides and the relative electrophoretic mobility of LDL (to 10 and 6% of the control, respectively). Furthermore, formation of conjugated dienes in LDL during Cu2+-induced oxidation was significantly reduced in the presence of 5 microM 6- and 7-hydroxydoxazosin (to 28% of tmax [time to maximum] of control). However, treatment of hypertensive patients with increasing doses of doxazosin (from 1 to 8 mg/day) for 8 weeks altered neither Cu2+-catalyzed, 2,2'azobis-(2-amidinopropane hydrochloride)-initiated, nor cell-mediated oxidation of patient LDL ex vivo. Furthermore, the total antioxidative capacity of plasma was unaffected by treatment. In conclusion, the present study shows that 6- and 7-hydroxydoxazosin have radical scavenging properties and protect LDL against in vitro oxidation. However, treatment of hypertensive male subjects with increasing doses of doxazosin for 8 weeks did not affect ex vivo oxidation of LDL.
