Objective: Visceral adiposity index (VAI) is a novel indicator for the assessment of visceral obesity. In this study, we aimed to evaluate the relationship between VAI and premature ejaculation (PE).

Materials and method: A total of 300 men were included in the study. Hundred and fifty men with PE and 150 men without PE (control). All men were evaluated for PE by premature ejaculation diagnostic tool (PEDT). VAI levels were calculated using body mass index (BMI), high density lipoprotein and triglyceride (TG) levels.

Results: Mean age of the study groups was 34.3?±?5.2 (30–60) years and the mean age of the controls were 35.9?±?5.3 (30–60) years. The men with PE had lower BMI, TG levels, waist circumference (WC) and higher high-density lipoprotein-cholesterol (HDL-C) levels. Mean VAI level was 4.13?±?0.7 in study group and 5.72?±?1.6 in control group, respectively. VAI levels were statistically higher in men without PE (p?Discussion: Our cross-sectional study demonstrated a negative correlation between VAI and PE. VAI is superior index for the evaluation and calculation the relationship between obesity and PE.  相似文献

This analysis of the thoroughgoing change effected in the US defense industry shows that the Pentagon’s traditional partners are taking a back seat behind private, for-profit service providers. These firms, which provide military services and the “information technology” necessary for modern warfare, now play a key role in the American national security system. Among the factors accounting for this unprecedented sharing of a classical government prerogative with private firms are the redefinition of the government’s role, the technological revolution and the strategic environment related to the global war against terrorism. This role-sharing brings new forces into play. The Defense Department is externalizing strategic activities without all the legislative and institutional means for regulating them, whence the risk of a crisis in the military establishment. The mixed systems coming out of this change are a driving force in altering the civilian and military capability to project power and intervene in the world.  相似文献

Dose response studies arise in many medical applications. Often, such studies are considered within the framework of binary-response experiments such as success-failure. In such cases, popular choices for modeling the probability of response are logistic or probit models. Design optimality has been well studied for the logistic model with a continuous covariate. A natural extension of the logistic model is to consider the presence of a qualitative classifier. In this work, we explore D-, A-, and E-optimal designs in a two-parameter, binary logistic regression model after introducing a binary, qualitative classifier with independent levels.  相似文献

This article traces the emergence of religious anti‐communist discourse in Finland's proto‐fascist Lapua Movement in the 1930s. Applying constructionist social problems theory, it discusses the constructions of communism as a religious social problem, Christian piety as a solution to the problem of godless communism, and the religious legitimation of violence. The article argues that by identifying Christianity with the Finnish nation the construction of communism as a religious problem—itself an outcome of the influence of revivalist Lutheran ministers in the leadership of the movement—resonated with the broader audience, but that this indigenous religious nationalism lost support with the increasing belligerence of the movement.  相似文献

Objective: Visceral adipose index (VAI) is a novel parameter for the evaluation of visceral obesity. As we know that obesity is a risk factor for erectile dysfunction (ED). So, in this study, we compared the VAI levels between the men with ED and without ED.

Materials and method: A total of 177 men were included in the study. Ninety-five men with ED and 82 men without ED (control). All men were evaluated for ED by Index of Erectile Function-5 items (IIEF-5). VAI levels were calculated using body mass index, high density lipoprotein and tryglyceride levels.

Results: Mean age was 53.5 (38–69) in men who have ED and 53.1 (34–69) in control. The men with ED had higher body mass index (BMI), triglyceride (TG) levels, higher waist circumference (WC) and lower high-density lipoprotein-cholesterol (HDL-C) levels. Mean VAI level was 5.18?±?2.50 in study group and 3.47?±?1.76 in control goup, respectively. VAI levels were statistically higher in men with ED (p?Discussion: The simplicity of WC and BMI measurement and TG and HDL assessment, make VAI an easily applicable index for the evaluation of visceral fat dysfunction. VAI can be useful index for the evaluation and calculation of erectile dysfunction risk.  相似文献

This paper is devoted to the estimation of the derivative of the regression function in fixed-design nonparametric regression. We establish the almost sure convergence as well as the asymptotic normality of our estimate. We also provide concentration inequalities which are useful for small sample sizes. Numerical experiments on simulated data show that our nonparametric statistical procedure performs very well. We also illustrate our approach on high-frequency environmental data for the study of marine pollution.  相似文献

The competition for highly skilled labour continues to be fierce and is taking a more institutionalized pattern across most of the developed world. This article sketches the changes in policies, legislations, and procedures across various EU countries and compares these with those of other developed countries.
The article shows that EU member states not only compete with non-EU countries and regions but also among themselves in order to attract and maintain sufficient flows of highly skilled labour.  相似文献
