Purpose: To study the value of auditory-perceptual and acoustic vocal analyses in assessments of children with nodules.

Design: Diagnostic test study.

Patients and interventions: A comparative study was carried R406 out including 100 children with videolaryngoscopic diagnosis of vocal nodules (nodule group-NG); and 100 children without vocal symptoms and with normal videolaryngoscopic exams (control group-CG). The age range of both groups was between

4 and 11 years. All children underwent auditory-perceptual vocal analyses (GRBASI scale); maximum phonation time and s/z ratio were calculated, and acoustic vocal analysis (MDVP software) were carried out.

Results: There was no difference in the values of maximum phonation time and s/z ratio between groups. Auditory-perceptual analysis indicated greater compromising of voice parameters for NG, compared to CG: G (79 versus 24), R (53 versus 3), B (67 versus 23) and S (35 versus 1). The values of acoustic parameters jitter, PPQ shimmer, APQ, NHR and SPI were higher for NG for CG. The parameter f0 did not differ between groups.

Conclusion: Compromising of auditory-perceptual Dinaciclib chemical structure (G, R, B and S) and acoustic vocal parameters (jitter, PPQ shimmer, APQ, NHR and SPI) was greater for children with nodules than for those of the control group, which makes them important methods for assessing child dysphonia.

“Introduction: The effect of angiotensin-converting enzyme (ACE) insertion/ deletion (I/ D) polymorphism on risk of diabetic nephropathy (DN) is still conflicting. The present meta-analysis was performed to evaluate the overall risk of this polymorphism associated with DN in different groups.

Materials and methods: A predefined search was performed on 14,108 DN cases and 12,472 controls from 63 published studies by searching electronic databases and reference lists of relevant articles.

Results: In this meta-analysis, we found a significant association between the Autophagy inhibitor ACE I/D polymorphism and the risk of DN for all genetic models (ID versus II: odds ratio [OR] = 1.12, 95% confidence interval [CI] 1.02-1.24;

DD versus II: OR = 1.27, 95% CI 1.13-1.44; allele contrast: OR = 1.15, 95% CI 1.08-1.23; dominant model: OR = 1.18, 95% CI 1.07-1.31; and recessive model: OR = 1.18, 95% CI 1.08-1.30, respectively). In stratified analysis by ethnicity and DM type, we further found that the Asian group with type 2 diabetes mellitus (T2DM) showed a significant association for all genetic models (ID versus II: OR = 1.25, 95% CI 1.07-1.47; DD versus II: OR = 1.57, 95% CI 1.24-1.98; allele contrast: OR = 1.30, 95% CI 1.15-1.46; dominant model: OR = 1.37, 95% CI 1.10-1.69; and recessive model: OR = 1.34, 95% CI 1.15-1.56, respectively).

Conclusions: Our study suggested that the ACE I/D polymorphism may contribute to DN development, especially in the Asian group with T2DM.”
