A study of knowledge and attitudes of registered nurses towards pain management in an urban hospital.
Nurses play a pivotal role in pain management. Unrelieved pain significantly interferes with patient's quality of life and is of great concern to nurses. The aim of this study was to determine the knowledge level and attitudes of nurses related to pain management. ⋯ Nurses' knowledge and attitudes scores were impressive but there is room for further improvement to pain management. Continuing education organized by the hospital had significant impact on the nurses. However, this education course has to be reinforced from time to time in order to improve patients' pain experiences.

Examining cerebral metabolic abnormalities in chronic obstructive pulmonary disease (COPD) patients by localized proton magnetic resonance spectroscopy (MRS).
The study was planned based on the hypothesis that cerebral metabolism is impaired in chronic obstructive pulmonary disease (COPD) by using localized in vivo proton magnetic resonance spectroscopy. ⋯ The findings of this study through the use of MRS confirmed that most patients with symptomatic COPD have cerebral metabolic abnormalities.

Lactic acidosis (LA) is the most common form of metabolic acidosis defined by values of lactate greater than 5 mmol / l and by a pH <7.34. The pathogenesis of LA involves hypoxic (type A) and non hypoxic (type B) causes which are often coexisting. Lactic acidosis is usual in hospitalized population especially in subjects in intensive care units, in which lactate levels on admission could be predictors of mortality even in the absence of organ dysfunction or shock. ⋯ The identification and the attempt to remove the cause of acidosis are main aims; treatment with sodium bicarbonate is a matter of debate as the data on the cardiovascular effects and mortality are unclear. The therapy with carbicarb, dichloroacetate or THAM has shown no specific advantages in terms of mortality. In experimental models of LA and shock the use of sodium-hydrogen exchanger-1 (NHE1) selective inhibitors reduces cell damage and inflammatory cytokines synthesis; it also improves cardiac performance and decreases mortality.
