Piperacillin-sulbactam versus piperacillin-tazobactam: a multicentre, randomised, single-blind, controlled clinical trial.

The objective of this study was to compare the efficacy and safety of piperacillin-sulbactam (PIP-SBT) and piperacillin-tazobactam (PIP-TAZ) in the treatment of bacterial respiratory and urinary tract infections. A randomised, single-blind, controlled clinical trial was performed. Differences in clinical efficacy, bacteriology and safety between the two groups were subjected to statistical analysis, including intent-to-treat (ITT) analysis. A total of 215 cases were enrolled, with 203 complete cases (99 PIP-SBT, 104 PIP-TAZ). A total of 209 cases (103 PIP-SBT, 106 PIP-TAZ) were included in the ITT analysis and a total of 212 cases (104 PIP-SBT, 108 PIP-TAZ) were included in the safety analysis. Overall efficacy rates of PIP-SBT and PIP-TAZ were 93.2% and 93.4%, respectively. Overall bacterial eradication rates of the two groups were 95% and 97.59%, respectively. Among the PIP-SBT group, eight patients (7.69%) had adverse events, including four probable drug-related events. Among the PIP-TAZ group, nine patients (8.33%) had adverse events, including one definitely drug-related and four probable drug-related events. All differences between the two groups were insignificant. PIP-SBT could be a suitable replacement for PIP-TAZ in the therapy of community-acquired respiratory and urinary tract infections caused by beta-lactamase-producing bacterial isolates.

The status of chronic conditions among the elderly and the influencing factors related to ADL of old people / 安徽医科大学学报

Objective　To survey about the health status, the activity of daily living conditions and their influencing factors among the elderly in Anhui province, to provide the reference for the current health service system reform of China. Methods　1 424 older persons were selected by Cluster sampling and random sampling methods. The chronic diseases prevalence rate, the damage of ADL among the elderly were investigated. The main influencing factors related to the damage of ADL was analyzed by single and multiple variable logistic regression model. Results　The older persons with aging, lose fare or divorce, multiple chronic disease and smoking habit were at high risk to ADL damage, but physical exercise, high income and well health knowledge may be protective factors which can reduce the ADL damage rate. Different kind of chronic diseases played the different role in the ADL damage among the elderly. Conclusion　The conditions of ADL damage remains serious among the elderly and there are a lot of affected factors. How to find the effective preventive intervention for the elderly and put it into practice, improve their quality of health living are new social problems in china.
