Prevalence of Spina Bifida Occulta and Its Relationship With Overactive Bladder in Middle-Aged and Elderly Chinese People / 대한배뇨장애요실금학회지

PURPOSE: To investigate the prevalence of spina bifida occulta (SBO) and its relationship with the presence of overactive bladder (OAB) in middle-aged and elderly people in China. METHODS: A cross-sectional community-based survey was carried out at 7 communities in Zhengzhou City, China from December 15, 2013 to June 10, 2014, where residents aged over 40 years were randomly selected to participate. All of the participants underwent lumbosacral radiographic analysis and relevant laboratory tests. A questionnaire including basic information, past medical history and present illness, and the OAB symptom score was filled out by all participants. Chi-square tests and logistic regression were used for data analysis with a P-value of 0.05). In men, age, SBO, and constipation were risk factors for OAB (P0.05). In women, age, SBO, and HCI were risk factors for OAB (P0.05). CONCLUSIONS: The prevalence of SBO is high and it is related to OAB in middle-aged and elderly people in China.

Effects of testosterone substitution on metabolic syndrome-related factors in hypogonadal males: a meta-analysis / 中华男科学杂志

<p><b>OBJECTIVE</b>To conduct a meta-analysis on the effects of testosterone on the related factors of metabolic syndrome in hypogonadal males.</p><p><b>METHODS</b>Based on the principles and methods of Cochrane systematic reviews, we searched the PubMed (1980 to August 2009), Embase (1980 to August 2009), the Cochrane Central Register of Controlled Trials and CNKI (1995 to August 2009) , and handsearched some relevant journals and conference proceedings as well. We also identified randomized controlled trials addressing the use of testosterone for the treatment of hypogonadism, screened the retrieved studies according to the predefined inclusion and exclusion criteria, evaluated the quality of the included studies, and performed a meta-analysis on the results of homogeneous studies using the Cochrane Collaboration's RevMan 5.0 software.</p><p><b>RESULTS</b>Six randomized controlled trials were included. The results of analysis indicated that testosterone substitution could significantly ameliorate fasting blood glucose, total cholesterol and insulin resistance in hypogonadism patients, and it could also reduce LDL, HDL, triglyceride and systolic blood pressure, though with no significant difference from the controls. However, there was insufficient evidence to show the effects of testosterone on waist circumference, waist-hip ratio and diastolic blood pressure.</p><p><b>CONCLUSION</b>Existing clinical evidence has demonstrated the positive effects of testosterone substitution on the improvement of insulin resistance, blood glucose and lipids, but due to the heterogeneity and high risk of bias in the included studies, the evidence might be insufficient to give full support to the demonstration. Further large-scale trials are required to define the metabolic effects of testosterone in the treatment of hypogonadism.</p>
