Background: The transcription factor 7-like 2 gene (TCF7L2) is an element of the Wnt signaling pathway. There is lack of evidence if TCF7L2 has a functional role in lipid metabolism and regulation of the components constitutes the metabolic syndrome (MetSyn). The aims of this study were to evaluate whether the risk allele of TCF7L2 gene polymorphism is associated with dyslipidemia and MetSyn. Materials and Methods: The MetSyn subjects were participated only based on the National Cholesterol Education Program – Third Adult Treatment Panel criteria. In this case–control study, the DNA from MetSyn patients without (n = 90) and with type 2 diabetes (T2D) (n = 94) were genotyped. Results: The results show that the genotype-phenotype for CC, CT/TT of TCF7L2 gene polymorphism correlated with body mass index and waist circumference in MetSyn and MetSyn + T2D subjects (r = −0.949 and r = −0.963, respectively). The subjects that only possess MetSyn but are not diabetics show the 2 h postprandial glucose and fasting blood glucose, glycated hemoglobin significantly lower (P < 0.05) than those subjects have both abnormality. The level of triglyceride in CT/TT carriers in MetSyn was higher than CC carriers (P = 0.025). A comparison with the controls subjects, the frequencies of the T allele in the groups of MetSyn (46.66%) and MetSyn + T2D (47.34%) show significantly different (P < 0.05). The odds ratios for T allele in (MetSyn)/(normal), (MetSyn + T2D)/(normal), and in (MetSyn + T2D)/(MetSyn) were 3.59 (95% confidence interval [CI], 1.33–9.67, P = 0.0093), 3.76 (95% CI, 1.40–10.07, P = 0.0068), and 1.08 (95% CI: 0.55– 2.11, P = 0.834), respectively. Conclusion: The results revealed the important insights essential for the role of TCF7L2 that the T allele of TCF7L2 plays a significant role in the susceptibility to dyslipidemia, MetSyn, and T2D.

Background: The most common clinical indication of aminoglycosides (AG) is the treatment of serious Gram-negative infections. The aim of this study was to evaluate plausible effects of atorvastatin on the biomarkers of acute kidney injury (AKI) in patients receiving amikacin. Materials and Methods: In this double-blinded randomized clinical trial, fifty patients (25 in each group) receiving amikacin (15 mg/kg/day) were randomly assigned to either atorvastatin (40 mg/day) or placebo (40 mg/day) groups for 7 days. Blood urea nitrogen (BUN), serum creatinine (SCr), and urinary neutrophil gelatinase-associated lipocalin (NGAL) levels were measured at days 0, 1, and 7 of amikacin treatment. Results: During the study period, 4 (8%) patients including two patients in each atorvastatin and placebo group experienced AKI. Urine NGAL/urine Cr did not change significantly between and within placebo and atorvastatin groups during the study period. Similarly, the mean changes in SCr, BUN, and urine NGAL/urine Cr values did not differ significantly between and within patients with and without AKI. Conclusion: Our data suggested that the changing pattern of urine NGAL/urine Cr ratio did not differ significantly between the atorvastatin and placebo groups during the early phase of amikacin treatment.

Background: The normal prostate-specific antigen (PSA) level in patients with urethral catheterization is a controversy. We designed this study to investigate the effect of nontraumatic urethral catheterization without urinary retention on serum PSA. Materials and Methods: Seventy patients scheduled for urethral catheterization before elective surgeries were randomly selected and included in the study. They were categorized into two age groups: 40–60 years (Group A) and over 60 years (Group B). Total PSA, PSA density, and free/total PSA were assessed before and after catheterization. Results: The PSA levels showed no statistically significant rise after urethral catheterization. The average of PSA level was 1.01 and 1.6 in A and B Groups, respectively, and changed to 1.38 and 1.80 in A and B Groups 1 day after catheterization (P > 0.05). Free/total PSA was 28.75 and 26 in A and B Groups before catheterization and changed to 28.35 and 27.5 in A and B Groups after catheterization (P > 0.05). Conclusion: Nontraumatic urethral catheterization has very little effect on PSA level and in patients with urethral catheter routine evaluation of PSA rising should be considered.

Background: Nonalcoholic fatty liver disease (NAFLD) includes a group of chronic liver disorders caused by irregular accumulation of fat in liver tissue. The current study aimed to evaluate chemical composition and the effect of fruit extract and essential oil of Pimpinella anisum in experimental model of NAFLD. Materials and Methods: Sixty rats were randomly divided into ten groups, six in each group. NAFLD was induced in rats using choline-deficient diet for 90 days, followed by 30 days of treatment with 25, 50, 100, and 200 mg/kg/day of hydroethanolic extract (AE) as well as 0.125, 0.25, and 0.5 mg/kg/day of essential oil (AO). Blood samples were collected in the final day, and lipid profile, aspartate aminotransferase (AST), alanine aminotransferase (ALT) as well as biomarkers of oxidative damage including myeloperoxidase, lipid peroxidation, total thiol molecules, and ferric-reducing ability of plasma were measured. Liver tissue sections of the sacrificed rats were also assessed histologically. Results: AE and AO significantly reversed increase in the plasma levels of total cholesterol, low-density lipoprotein, and triacylglycerol and decrease in high-density lipoprotein level in a dose-dependent manner (P < 0.05). Serum levels of AST and ALT were also significantly modified by treatment with AE and AO (P < 0.05). Biomarkers of oxidative stress were modulated by administration of AE and AO (P < 0.05). Histological assessments also confirmed the effectiveness of treatments by reduced macrovesicular steatohepatitis. Conclusion: It could be concluded that P. anisum fruit extract and essential oil have beneficial effects in the treatment of NAFLD. Further studies are necessary to confirm safety and efficacy of this medicinal plant in clinical setting.

Background: Blood neutrophil to lymphocyte ratio (NLR) and mean platelet volume (MPV) both have been used as a simple marker of inflammation in many disorders. Here, we aimed to investigate the relationship between NLR, MPV, and familial Mediterranean fever (FMF). Materials and Methods: In this retrospective study, the files of FMF patients in pediatric rheumatology outpatient clinic were reviewed. There were 160 participants (68.4%) in the FMF patient group and 74 participants (31.6%) in the control group. Ninety of patients were in attack-free period, and 70 were in attack period. Results: The highest values of NLR were found in the patients at attack period. Patients in attack-free period and the participants in control group had similar levels of NLR (1.71 ± 0.83 and 1.91 ± 1.86 respectively) (P = 0.457), and they had lower ratios than the patients did at attack period (4.10 ± 3.11) (P < 0.001 for both). There was no significant difference between MPV values of attack patients (8.35 ± 4.91) and attack-free patients (8.43 ± 1.15) (P = 0.074). MPV values of attack patients and attack-free patients were significantly higher than control group (7.99 ± 0.81) (P < 0.001 for both). Conclusion: NLR ratio may indicate FMF attack period. Since there was no significant difference between attack-free patients and control groups, NLR ratio cannot be used as a subclinical inflammation marker. However, NLR could be a useful predictor of inflammation in FMF patients. On the other hand, since our attack and attack-free patients have similar MPV values and both had greater MPV values than control group, we suggest that MPV may be used to show subclinical inflammation.

Background: Reduced bioavailability of nitric oxide (NO) and the T-786C polymorphism of endothelial nitric oxide synthase (eNOS) gene have been reported as risk factors for the development of coronary artery disease (CAD) with conflicting results. We investigated the association of plasma NO levels, T-786C genetic polymorphism, and gene expression levels of eNOS with CAD risk in an Iranian subpopulation. Materials and Methods: Studied population included 100 patients with angiographically verified CAD and 100 ethnically matched controls. Analysis of T-786C genetic polymorphism and gene expression levels of eNOS was conducted by polymerase chain reaction (PCR) restriction fragment length polymorphism and real-time reverse transcription-PCR methods, respectively. Plasma levels of NO were measured using Griess method. Results: The CC genotype distribution (15% vs. 6%, P = 0.011) and minor C allele frequency (36.5% vs. 21.5%, P = 0.001) of eNOS T-786C polymorphism differed significantly between CAD patients and control. Furthermore, eNOS T-786C polymorphism was more common among smoker than nonsmoker CAD patients (27.7% vs. 7.8%, P = 0.044). The association of the eNOS T-786C polymorphism with the severity of CAD (number of diseased vessel) was significant (P < 0.05). The gene expression levels of eNOS were significantly lower in the heterozygote (0.49 ± 0.1, P = 0.023) and mutant homozygote (0.36 ± 0.09, P = 0.011) genotypes than that of wild-type genotype (P < 0.05). In addition, NO levels were significantly lower in CAD patients compared with control subjects (42.62 ± 12.26 vs. 55.48 ± 16.57, P = 0.002) and showed intergenotypic variation in the CAD patients. Conclusion: Our study indicated that reduced NO levels and eNOS T-786C genetic polymorphism are significant risk factors for the development and severity of CAD in the Iranian population.
