Visceral adiposity index is associated with premature ejaculation inversely: a cross-sectional study

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.     

Dialectical behavior therapy for patients with borderline personality disorder.

This study examined the effectiveness of dialectical behavior therapy (DBT) in the treatment of people diagnosed with borderline personality disorder (BPD). The frequency of self-injurious behaviors of 15 women hospitalized on a DBT unit was traced over a 4-week period. Data on self-injurious behaviors and the use of the DBT approach were collected from a review of incident reports and patients' charts. The self-injurious behaviors decreased by almost 50%. In addition, four RNs, who were involved on the DBT unit both before and after the institution of the treatment approach, were interviewed. Semi-structured interviews were conducted to determine the nurses perceptions of the effectiveness of DBT. Their responses were uniformly positive. The most commonly occurring phrase was "it works."     

A useful approach to identify the multicollinearity in the presence of outliers

The presence of outliers in the data sets affects the structure of multicollinearity which arises from a high degree of correlation between explanatory variables in a linear regression analysis. This affect could be seen as an increase or decrease in the diagnostics used to determine multicollinearity. Thus, the cases of outliers reduce the reliability of diagnostics such as variance inflation factors, condition numbers and variance decomposition proportions. In this study, we propose to use a robust estimation of the correlation matrix obtained by the minimum covariance determinant method to determine the diagnostics of multicollinearity in the presence of outliers. As a result, the present paper demonstrates that the diagnostics of multicollinearity obtained by the robust estimation of the correlation matrix are more reliable in the presence of outliers.     

The Attitudes of Social Work Students Toward End-of-Life Care Planning

This study examined the attitudes of social work students toward end-of-life care planning, as well as their degree of willingness to engage in this area of social work practice. Factors associated with their attitudes were measured through structured surveys completed by 102 social work students (N = 102) at a school of social work in the southeast. Results indicated that these social work students tended to have positive attitudes toward end-of-life care planning in general. Moreover, these attitudes were positively associated with preference for pain relief treatment, higher levels of comfort when discussing death, more emphasis on self-determination, and apprehension of conflicts of self-determination. The results of this study underscored the increased societal need for recognition of personal preferences in end-of-life care, higher levels of comfort when discussing death, and an increased commitment of social workers' to maintaining the ethical principle of the client's right to self-determination in end-of-life planning. While this is not surprising, it points to a continuing need to re-assess where the field stands in its preparation of social work professionals who will work closely with people who are dying and their families.     

Increased visceral adiposity index associated with sexual dysfunction in men

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.     

Visceral adiposity index is associated with benign prostatic enlargement in non-diabetic patients: a cross-sectional study

Objective: To evaluate the association between visceral adiposity index (VAI) - a novel indicator for the assessment of visceral adipose tissue and prostate enlargement in non diabetic patients.

Material and methods: Four hundred patients who were admitted to the Urology clinic between January and December 2014 with complaints of BPH(benign prostatic hyperplasia )/LUTS(male lower urinary tract symptoms)were enrolled in this cross-sectional study. Patients were divided into two groups according to their prostate volume and international prostate symptom score (IPSS) value. They were compared in terms of age, body mass index (BMI), VAI, prostate volume, PSA, post micturional residual volume (PMRV), uroflowmetry Q max value, triglyceride (TG), high density lipoprotein-cholesterol (HDL-C) and fasting blood sugar (FBS).

Results: Although univariate analyses reveal that age, BMI, waist circumference (WC), FBS, TG, HDL-C level and TG/HDL ratio were correlated with prostate volume, only age [1.125 OR (1.088–1.164), p?=?.00001], BMI [1.119 OR (1.040–1.204), p?=?.003], TG [1.043 OR (1.016–1.071), p?=?.002], HDL-C [0.923 OR (0.860–0.990), p?=?.025] and VAI [1.194 OR (1.110–1.305), p?=?.011] were statistically significant in multivariate analysis. A positive correlation was found between VAI value and prostate volume in the Spearman correlation test (r?=?0.29, p?=?.00001). The calculated area under the curve (AUC) for prostate volumes of 30, 40 and 50?ml were 0.680 (0.621–0.738), 0.625 (0.570–0.681) and 0.590 (0.528–0.652), respectively.

Conclusion: Our study revealed a positive correlation between VAI and prostate volume. Our results are needed to be tested with well-designed randomized prospective cohort studies.     

A dynamic econometric model of suicides in Turkey

This study is the first attempt to empirically examine the determinants of suicides in the case of Turkey using the time-series data for the period 1974–2007. This research proposes that the suicides in Turkey are related to some economic and social factors and they exhibit a dynamic relationship amongst them. Auto-Regressive Distributed Lag (ARDL) approach to cointegration testing procedure is employed to obtain the short-run and long-run elasticities of suicides with respect to per capita real income, divorce rates, urbanization and liquidation. The empirical results reveal that the urbanization has the highest impact on suicides, which is followed by per capita real income and liquidation. The results also provide some important policy recommendations to reduce suicides.     

The Effect of Board of Directors’ IT Awareness on CIO Compensation and Firm Performance

Chief information officers (CIOs) play increasingly strategic roles in firms in this competitive global economy, which is now largely powered by information technology (IT). However, research has shown a lack of board of directors’ oversight on CIO‐ and IT‐related issues. Drawing on agency, resource dependence, and alignment theories, we investigate the effect of board of directors’ IT awareness on CIO compensation structure and firm performance. We conduct cross‐sectional time series analyses of data collected from various sources. Our study underlines three important findings. First, we show that some commonly known executive compensation determinants, such as individual characteristics and governance structure, do not have significant effects on CIO compensation structure. Second, with regard to CIO compensation structure, firms respond to increasing information asymmetry differently according to the level of IT awareness of their boards. Finally, firms perform better when their boards have higher levels of IT awareness, and this positive effect of IT awareness is considerably larger in IT intensive industries. Overall, our study provides empirical support for the important role of boards’ IT awareness in shaping CIO compensation and improving firm performance. Our results suggest that boards with functional area knowledge—or higher IT awareness in this case—can more effectively monitor and better incentivize executives, and consequently lead to better firm performance.     

Perceptions of power and the management of environmental conflict: Forest politics in British Columbia

Political actors' perceptions of the contexts in which they act influence their strategies and behavior. A key element of political contexts is the configuration of power with respect to a conflict. We interviewed 28 individuals involved in British Columbia forest politics to determine their perceptions of the configuration of power, the nature of their political behavior, their dispositions with respect to institutionalized conflict resolution processes, and their policy goals. Our analysis generated two sets of conclusions. First, the B.C. government's efforts to address forest conflict will be hindered by the inconsistency between the conflict management strategy they have chosen and the mental models of politics held by key political actors. Second, the subjective realities of political actors can be used to explain variation in political behavior.
