Sildenafil versus continuous positive airway pressure for erectile dysfunction in men with obstructive sleep apnea: a meta-analysis

Objective.?To evaluate the effectiveness of sildenafil versus continuous positive airway pressure (CPAP) for patients with erectile dysfunction (ED) and obstructive sleep apnea (OSA).

Methods.?This is a meta-analysis of a randomized controlled trial. The main outcome measures for effectiveness were the percentage of successful intercourse attempts, International Index of Erectile Function (IIEF) domain scores (erectile function, EF) and the satisfaction levels of the patients and their partners with the treatment for ED.

Results.?Two randomized controlled trials totaling 70 patients were included. Meta-analysis results are as follows: after 12 weeks of treatment, patients under sildenafil demonstrated a significant advantage over under CPAP in terms of the percentage of successful intercourse attempts [OR?=?3.24, 95% CI (2.37–4.43)], EF scores [WMD?=?3.57, 95%CI (1.68–5.45)], and the satisfaction levels of the patients and their partners with the treatment for ED [OR?=?3.56, 95% CI (1.27–9.98)].

Conclusion.?Current clinical studies might confirm that both therapeutic methods were safe and effective, but sildenafil was superior to CPAP in the treatment of ED in men with OSA. We conclude that new therapeutic agents or a combination of the two methods should be studied further.     

Inverse association between total testosterone concentrations,incident hypertension and blood pressure

Background.?Studies on the relationship between testosterone concentrations and blood pressure have yielded inconsistent results. Therefore, this study investigated the prospective association of total testosterone (TT) concentrations with risk of incident hypertension and blood pressure change in 1484 men aged 20–79 years.

Methods.?Data from the population-based Study of Health in Pomerania, Germany, were used. Serum TT concentrations, measured by chemiluminescent enzyme immunoassays, were categorised into age-specific quartiles. Generalised Estimating Equation (GEE) models, adjusted for age, waist circumference, physical activity, smoking and alcohol consumption were specified.

Results.?During a median follow-up time of 5.0 years, the prevalence of hypertension increased from 50.6% to 57.1%. TT concentrations were significantly lower in men with baseline and incident hypertension. Analyses revealed that men with baseline TT concentrations in the lowest quartile had an increased risk of incident hypertension (odds ratio (OR), 1.19 (95% CI, 1.10–1.28)) compared to men with higher TT concentrations. Furthermore, we found a significant inverse association of TT concentrations and blood pressure, showing that men with baseline TT concentrations in the lowest quartile showed the slightest change in systolic blood pressure (?6.01?mmHg), diastolic blood pressure (?2.11?mmHg) and pulse pressure (?3.98?mmHg). Sensitivity analyses in a subpopulation of men without antihypertensive medication confirmed these findings.

Conclusion.?These results show that low male TT concentrations are predictive of hypertension, suggesting TT as a potential biomarker of increased cardiovascular risk.

改制后的师范专科学校教师心理压力及调适

伴随教师教育改革,升格后的师范专科学校教师由于对学校未来预期水平的不确定、教师个体对未来教育的应对能力有限、教师对现有教学工作不投入,缺乏自我效能感等原因,产生强大的心理压力。据此,教师自身和学校应积极应对,教师要明确认识,积极适应;立足教学,做研究型教师,增强自身竞争力;学校要创设条件,鼓励教师在职进修,增强学校竞争力;教育部门要加强对师范专科学校教育科研的支持、指导。     

"沉默的螺旋"在传统大众传播环境和网络传播环境中表现方式的差异

“沉默的螺旋”是一种传统大众传播的强效果论。结合CMC(以电脑为媒介的传播)与FTF(面对面的传播)有关群体压力方面的研究成果,认为网络受众从众心理的动因继续存在,从众现象依旧普遍,因此,产生“沉默的螺旋”机制的基本条件在网络空间中仍然存在,并分析了“沉默的螺旋”在传统大众传播环境和网络传播环境中表现方式的差异。     

从国际游资动向看人民币的升值可能

2002年以来,日本、美国等国家纷纷要求人民币升值,受这种升值预期的影响,热赌人民币升值的国际游资几进几出中国内地及周边金融市场,人民币升值压力日益加大。从人民币升值的利弊分析,在短期内中国仍以保持稳定的汇率为佳。     

成人重返课堂的教育实践探析

教育制度和个体教育实践总是一个相互模塑的过程,成年人教育实践为成年教育制度的建立和完善提供现实基础和根据,而成人教育制度对成人教育起到促进或制约作用。立足于农村中小学教师在成年期攻读研究生学位的继续教育实践,从微观的角度探讨其在学术科研、生活状况、情感世界和职业期望等方面表现出来的苦恼、不安、焦虑、困惑、迷惘、沮丧、无奈等不适应问题,为成年教育理论的发展和成年教育制度的完善提供第一手经验资料。
