Investigation of nursing interruptions during endoscopic surgeries / 中国实用护理杂志

through observation recorded source, type, the affairs occupying nurses when the interruptions occurred, results, years of experience and start-stop time. Results Total 702 interruptions had been observed, reasons accounting for interruptions:surgeons (23.1%,162/702) and circumstances (16.7%,117/702);the major type: intrusion (39.7%,279/702); the affairs occupying nurses when the interruptions occurred:sterile operation(19.2%,135/702) and equipment inventory(14.7%,103/702); the major result: negative (84.6%,594/702). Conclusions There is a high level frequency of interruption events, intraoperative workflows need to be well designed to reduce unnecessary interruptions.

Correlation study between brain N-acetylaspartate and executive function in alcoholics / 中华行为医学与脑科学杂志

Objective To investigate the changes of the N-acetylaspartate(NAA) concentrations in different brain regions and executive function skills in alcohol dependence,and to study the relationship between NAA levels and cognitive functions in subjects.Methods 49 male,non-smoking,alcohol-dependent patients and 45 healthy control subjects were measured with Proton 1H Magnetic resonance spectroscopy (MRS) and Wisconsin Card Sorting Test (WCST).Results Alcoholics had lower NAA/Cr ratios in prefrontal grey matter(GM) (1.59± 0.13) and white matter(WM) (1.58±0.12) regions and performed poorly on executive function tests compared to controls (P＜0.001).NAA/Cr in left prefrontal regions positively correlated with certain parameters of EF testing (number of correct responses 30.37± 3.73,perseverative errors 11.49± 3.39,random errors 6.18± 2.64,categories completed 2.08± 1.59)in alcoholic group (P＜0.01).NAA/Cr in prefrontal WM regions correlated with certain parameters of EF testing in alcoholic group (number of correct responses r=0.379,categories completed r=0.433,P＜ 0.05).Conclusion Long-term,chronic alcoholism will damage neuronal viability and cognitive functions,which suggests that NAA concentrations can reflect the extent of damage of cognitive functions with decreased levels reflecting neuronal loss.
