Relationship between organizational climate and empowerment of nurses in Menoufiya hospitals, Egypt

One factor influencing the outcome of care may be the nursing staff's experience of organizational work climate. We compared organizational climate and nurse's empowerment in specialty units at 2 hospitals in Egypt. Data were collected from 164 diploma school staff nurses using 2 tools: the situational outlook questionnaire to assess organizational climate and the psychological empowerment in the workplace questionnaire. There was no statistically significant difference in the level of organizational climate between the 2 hospitals, which the majority of nurses classified as moderate. Most nurses reported a moderate level of empowerment in both hospitals and there was a statistically significant positive correlation between organizational climate and nurse's empowerment

role of direct intrapulmonary artery isuprel injection pre and during CPB on pulmonary hypertension secondary to rheumatic mitral valve disease

The effect of direct pulmonary injection of isuprel pre and during cardiopulmonary bypass [CPB] on pulmonary vasomotor dynamics was studied in 30 patients undergoing mitral valve replacement for mitral valve disease [MVD] with pulmonary hypertension [PH]. A 30% reduction in mean pulmonary artery [PA] pressure [from 65.6 mm Hg +/- 8.3 to 44.2 mm Hg +/- 7.6; P < 0.001] and a 48.4% reduction in pulmonary vascular resistance index [PVRI] from 12.08 +/- 4.14 to 5.16 +/- 1.6 IU/m[2]; P < 0.001] were observed after isuprel. There were no significant changes in mean systemic arterial pressure [85.5 mm Hg +/- 12.5 to 83.2 mm Hg +/- 7.3]. Left and right atrial pressures decreased by 22% and 9% respectively

comparative study on the shear bond strength of some resinous dentin adhesives

The shear bond strength between composite and dentine after using adhesive of different modes of actions was evaluated in this study. Freshly extracted sound human molars were selected, embedded in steel rings using improved dental stone. The buccal surfaces of 180 specimen were cut to expose dentine using a milling machine. The denuded dentine surface were either untreated or treated by EDTA or ferric oxalate. Two different adhesive systems bonding either to the organic or inorganic portions of dentine were used. A combination of both the organic and inorganic dentine adhesive was also used. A light cured composite resin was placed on the treated dentine surface by a teflon ring. The specimen were divided into nine equal groups and tested for shear bond strength using a universal testing machine. The results revealed that the highest mean shear bond strength scores were obtained with the use of the combination of dentine adhesive followed by the adhesive bonding to the organic component of dentine. Furthermore, the use of EDTA for the surface treatment of dentine was found to greatly improve the shear bond strength values of the dentine bonding agents to dentine surface
