Spearman Correlation Test (spearman + correlation_test)
Selected AbstractsHigh levels of anxiety and depression have a negative effect on quality of life of women with chronic pelvic painINTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 5 2009A. P. M. S. Romão Summary Background:, Chronic pelvic pain (CPP) is a common and complex disease whose cause is often clinically inexplicable, with consequent difficulty in diagnosis and treatment. Patients with CPP have high levels of anxiety and depression, with a consequent impairment of their quality of life. Aims:, The objective of this study was to determine the prevalence of anxiety and depression and their impact on the quality of life of women with CPP. Materials and methods:, A cross-sectional controlled study was conducted on 52 patients with CPP and 54 women without pain. Depression and anxiety were evaluated by the Hospital Anxiety and Depression Scale, and quality of life was evaluated by the World Health Organization Quality of life Whoqol-bref questionnaire. Data were analysed statistically by the Mann-Whitney U -test, the Fisher exact test, chi-square test and Spearman correlation test. Results:, The prevalence of anxiety was 73% and 37% in the CPP and control groups, respectively, and the prevalence of depression was 40% and 30% respectively. Significant differences between groups were observed in the physical, psychological and social domains. Patients with higher anxiety and depression scores present lower quality of life scores. Discussion:, The fact that DPC is a syndromic complex, many patients enter a chronic cycle of search for improvement of medical symptoms. The constant presence of pain may be responsible for affective changes in dynamics, family, social and sexual. Initially the person is facing the loss of a healthy body and active, to a state of dependence and limitations. In this study, patients with higher scores of anxiety and depression scores had lower quality of life and patients with lower scores of anxiety and depression had scores of quality of life. These results show that perhaps the depression and anxiety may be related to the negative impact on quality of life of these patients. Conclusion:, In view of this association, we emphasise the importance of a specific approach to the treatment of anxiety and depression together with clinical treatment to improve the quality of life of these patients.

To study the blood flow patterns of utero-ovarian circulation in polycystic ovary syndrome (PCOS) and to assess their relationship with clinical, metabolic, and hormonal data. Methods. Forty-three women with PCOS and 43 age-matched healthy controls underwent Doppler examination of the utero-ovarian circulation in the follicular phase. Demographic, hormonal, and metabolic parameters were determined. Student's t -test, ,2 -test, and Spearman correlation test were used for statistical analysis. Results. The ovarian artery pulsatility index (PI), resistance index (RI), and SD ratios were significantly lower in PCOS than in controls on the right side (p < 0.001, p = 0.02, p = 0.001, respectively) as well as on the left side (p < 0.001, p < 0.001, p < 0.001, respectively). The uterine artery systolic/diastolic (S/D) ratio was higher on both sides (p = 0.01) and the PI was higher on the left side (p = 0.02) in PCOS than in controls. The right uterine artery PI was positively correlated with luteinizing hormone and hemoglobin (r = 0.417, p = 0.043; r = 0.427, p = 0.033, respectively), the right uterine artery S/D was positively correlated with body mass index (r = 0.479, p = 0.015), and the left uterine artery PI was positively correlated with insulin (r = 0.458, p = 0.021). Conclusion. Doppler sonography of the utero-ovarian circulation may contribute to the evaluation of PCOS patients and a better understanding of the pathophysiology of this syndrome. © 2007 Wiley Periodicals, Inc.

GHAZAL Summary, To evaluate and correlate the two-body wear of human enamel and nano-filled composite resin teeth with the loading forces used in a dual-axis chewing simulator. Three groups of human enamel and three of nano-filled composite resin teeth were tested in a chewing simulator. Zirconia ceramic balls were used as antagonists. The teeth were tested with three different loading forces (20, 49 and 78 N). Wear was analysed by measuring the volume and vertical substance loss using a laser scanner after 300000 chewing cycles. Data were statistically analysed using two-way anova followed by the Scheffé test (P , 0·05). Spearman correlation test was used to determine whether there was a relationship between the loading force and the degree to which the human enamel and composite resin had worn. An increase in the loading force significantly increased the wear of composite resin and of human enamel. The effect of the loading force on the wear was statistically significant at the 0·001 level. Human enamel showed a lower volume and vertical substance loss than composite resin under loading forces of 20 and 49 N and lower vertical loss under loading force of 78 N. The correlation between the volume loss and loading force was statistically significant (r = 0·616, P < 0·001). Nano-filled composite resin and human enamel exhibited different amount of wear under different loading forces. In general, human enamel showed less vertical substance loss than nano-filled composite resin. [source] Predictive value of renal histological changes for postoperative renal function improvement in children with congenital ureteropelvic junction stenosisINTERNATIONAL JOURNAL OF UROLOGY, Issue 6 2002Ahmet Erbagci Abstract Background: The aim of this study was to evaluate the relationship between renal function, as measured by diuretic radionuclide renography, and the outcome of pyeloplasty. A study was designed to evaluate renal parenchymal biopsy specimens derived from children undergoing corrective surgery for ureteropelvic junction (UPJ) stenosis, and compare these to preoperative and postoperative renal function status. Methods: Thirty-five children with congenital unilateral UPJ stenosis were evaluated. In addition to all conventional diagnostic procedures for UPJ stenosis, differential renal functional (DRF) activity was assessed in each of these children by obtaining 99mTc diethylenetriaminepentaacetic acid renogram curves. All children underwent dismembered pyeloplasty, and follow-up renogram evaluation was conducted 6 and 12 months after surgical repair. Biopsy specimens from renal cortical regions obtained during the surgical correction of UPJ stenosis were evaluated, and changes in renal histology were graded from I to V according to their severity. Spearman's correlation test was used to compare the histological evaluation results and the basal, 6- and 12-month follow-up DRF findings. A Wilcoxon paired test was used to evaluate statistical differences between values. Results: The findings showed a positive correlation between the severity of histological changes and DRF activity. All kidneys (22) with a DRF activity value of < 40% preoperatively demonstrated at least grade III changes when biopsy specimens were examined. Of children with a DRF activity value > 40% (13), only three showed severe histological changes. Histological grades were correlated between basal (r = ,0.4; P = 0.019), 6-month (r = 0.54; P = 0.002) and 12-month (r = 0.54; P = 0.02) findings. In the Wilcoxon paired test, there was a statistically significant difference between basal and 6-month values (P < 0.05), and also between basal and 12-month values (P < 0.01). There was no statistically significant difference between 6- and 12-month values (P > 0.20). Conclusion: Comparative evaluation of postoperative renal function with DRF activity and renal parenchymal histological alterations revealed a close correlation in terms of renal function improvement potential following reconstructive surgery in children with UPJ stenosis.
