Background: Cichorium intybus L. (Kasni) distillate is widely used in Eastern countries as a safe herbal drink to improve male fertility. However, the potential effects on fertility parameters and possible adverse effects have not been studied experimentally. The current study aims to evaluate the impact of Cichorium intybus L. distillate (CD) on male mice fertility.
Methods: In the present study (Shiraz, Iran), 30 male mice (30-35 g) were divided into three groups. 10 mice received distilled water (DW) for five weeks as the control group. Another 10 mice, named group CD1/2, received chicory distillate of 1/2 dilution, and the other 10 mice received chicory distillate of CD1/4 dilution as CD1/4 group, ad libitum for three weeks, and they received DW for two weeks afterward. Experimental mice were sacrificed on day 35, and sperm analysis and sera collection were performed for further investigation of FSH, LH, testosterone, and some liver and kidney function parameters. We used the left testis for stereological analysis, and the right one was excised to investigate the expression of the androgen receptor gene. For statistical analysis using SPSS 18.0, mean±SD values were analyzed by one-way analysis of variance (ANOVA) with Dunnett's analysis as post hoc to compare between groups. In stereological investigations, the Kruskal-Wallis method was used for pairwise comparisons to compare groups. The P value was considered statistically significant at P<0.05.
Results: Treatment with CD1/2 resulted in the elevation of serum FSH (P=0.002), LH (P=0.009), testosterone (P=0.034), seminiferous tubule epithelium volume (P=0.029) and length (P=0.028), and Leydig cells number (P=0.009) in comparison with the control group. Administrating CD1/2 (P=0.038) and CD1/4 (P=0.013) significantly increased sperm count compared to the control group.
Conclusion: The results revealed that using chicory distillate can improve hormone levels and sperm count in male mice.

Background: Type 2 diabetes mellitus (T2DM) is associated with sleep disorders, which in turn may lead to anxiety and depression. Sleep deprivation impairs glucose metabolism causing a decrease in insulin sensitivity and glucose tolerance. The present study aimed to determine the association of insomnia with anxiety and depression in patients with T2DM.
Methods: A cross-sectional study was conducted in 2020 at the Endocrinological Department of City Clinical Hospital №1, affiliated with Astana Medical University (Astana, Kazakhstan). A total of 376 patients with decompensated T2DM were included in the study. Insomnia was assessed using the Pittsburgh Sleep Quality Index (PSQI) and Insomnia Severity Index (ISI). Anxiety and depression were assessed using the Hospital Anxiety and Depression Scale (HADS). Multivariable logistic regression was used to assess the association of insomnia with anxiety and depression.
Results: All patients showed signs of sleep disturbances. Based on the HADS cutoff score >8, anxiety and depression were observed in 48 (12.80%) and 46 (12.20%) patients, respectively. PSQI, ISI, and HADS indicators were associated with an increased risk of anxiety and depression symptoms. In terms of anxiety, the adjusted odds ratio for PSQI and ISI scores were 1.09 (P=0.08) and 1.07 (P=0.01), respectively. These for depression were 1.10 (P=0.06) and 1.07 (P=0.01), respectively.
Conclusion: Sleep quality is an important indicator of psychological health in patients with T2DM, especially those who exhibit signs of anxiety and depression.

Management of the posterior urethral valve (PUV) is a clinical challenge in pediatric urology. We report the results of a modified valve ablation method without using a pediatric resectoscope and thermal energy. Patients were selected from children with PUV who were referred to the pediatric urology clinic of Shahid Labbafinejad Hospital, Tehran, Iran, and have undergone endoscopic valve ablation surgery between May 2019 to May 2021. Ten male patients with PUV underwent mechanical valve ablation without the use of the conventional pediatric resectoscope, and thermal energy was replaced by a 6F semi-rigid urethroscope and 3Fr ureteral catheter. Patients were assessed both pre-and postoperatively using serum creatinine, urinary tract ultrasound imaging, and voiding cystourethrography. The mean age was 23.88±30.13 months (range= 25 days to 8 years). Four out of 10 patients (40%) had elevated serum creatinine, and seven had unilateral or bilateral hydroureteronephrosis (70%). No major complications were reported according to Clavien-Dindo Classification System. The level of serum creatinine, the grade of hydroureteronephrosis, and the ratio of the prostatic urethra to anterior urethra diameter in postoperative voiding cystourethrography were decreased. A decrease in serum creatinine level occurred in patients after valve ablation, but this decrease was not statistically significant (P=0.059). The decrease in hydroureteronephrosis grade on the right (P=0.006) and left (P=0.022) was statistically significant. There was no evidence of urethral stenosis or need for repeating resection. It can be concluded that our mechanical valve ablation method might be a safe and effective technique for PUV ablation.

In this study, 100 saliva samples, including 57 (57%) men and 43 (43%) women, were examined. The mean age of the case group was 71.6±10.2 years, and the mean age of the control group was 67.3±15.3 years. All the case and control groups were matched. Table 1 shows the viruses that were found in the case and control groups. In the dentate subjects, no HSV-1 and HSV-2, CMV and EBV, and HHV-6 were detected. However, 4 (8%) of the case group were infected with HSV-1, and 1 (2%) of them were infected with HSV-2. Moreover, 1 (2%) of the case group had EBV infection, 2 (4%) had CMV infection, and 2 (4%) had HHV-6 infection. There were no underlying diseases in the control group. There was no statistically significant correlation between underlying diseases such as hypertension and diabetes mellitus and HSV-1 and HSV-2 prevalence (P=0.412). Furthermore, no statistically significant correlation was found between the underlying diseases and EBV, CMV, and HHV-6 infection (P=0.406). HSV-1, HSV-2, HHV-6, EBV, and CMV were detected in the saliva of denture wearers. The Chi square test indicated a higher and more significant HSV-1 value among denture wearers. For the other viruses, however, there was no significant difference between case and control groups. A previous study found HHV-8 in denture wearers’ saliva, 5 similar to what we detected regarding HSV-1. Except for HSV-1, the findings of the present study indicated no significant difference between the case and control groups. Therefore, further studies with larger sample sizes are recommended. This study could pave the way for further research regarding the significance and risk of these viruses in edentulous cases.

Background: Anti-tuberculosis drug-induced hepatotoxicity can result from genetic polymorphism of the isoniazid (INH) metabolizing enzyme. This study aimed to determine the effect of genetic polymorphism of N-acetyltransferase 2 (NAT2) and cytochrome P450 2E1 (CYP2E1) genes on serum isoniazid level and drug-induced hepatotoxicity.
Methods: A cross-sectional study was conducted on 120 patients (with and without hepatotoxicity) with pulmonary tuberculosis from June 2019 to April 2022 in Tehran (Iran). High-performance liquid chromatography was used to measure the serum concentration of INH and acetylisoniazid (AcINH). NAT2 and CYP2E1 genotypes were determined using polymerase chain reaction and restriction fragment length polymorphism methods. Data were analyzed using SPSS software (version 22.0) with independent two-sample t test, Chi square test, or Fisher's exact test. P<0.05 was considered statistically significant.
Results: A total of 40 patients showed hepatotoxicity. The risk of anti-tuberculosis drug-induced hepatotoxicity was significantly higher in patients who are slow acetylator (SA) phenotype than in rapid or intermediate acetylator (P<0.001). NAT2*4/*4 genotypes were not found in patients with hepatotoxicity. The frequency of NAT2*5 and NAT2*6 haplotypes and serum INH concentration was significantly higher in patients with hepatotoxicity than in those without (P=0.003, P<0.001, and P<0.001, respectively). NAT2*4 haplotype was correlated with protection against hepatotoxicity. A combination of SA and CYP2E1 C1/C1 genotype was significantly associated with hepatotoxicity (P<0.001).
Conclusion: Hepatotoxicity in Iranian patients with tuberculosis was confirmed due to the presence of NAT2 SA polymorphism. Determining NAT2 and CYP2E1 genotypes and/or INH concentration can be a valuable tool to identify patients susceptible to hepatotoxicity.

Background: The association between metabolic syndrome (MetS) and breast cancer may significantly impact the mortality and incidence of breast cancer. This study aimed to assess the association between MetS risk factors and immunohistochemical (IHC) profiles in women with breast cancer.
Methods: This cross-sectional study used the medical records of 300 breast cancer patients with an average age of 53.11±12.97 years in the Chemotherapy and Radiation Therapy Clinic of Dr. Anbiai, Tehran, Iran (2020-2021). The cases were divided into five subgroups including luminal A, luminal B (HER-2-), luminal B (HER-2+), HER-2 overexpressing, and triple negative.
Results: There was no difference in the prognostic indicators between the presence and absence of MetS in women with breast cancer. A higher proportion of luminal A tumors (39.3%), luminal B (HER-2+) (25%), triple-negative (17%), luminal B (HER-2-) (10.7%), HER-2 overexpression (8%) was observed in women with MetS than those without MetS. Multivariate logistic regression analysis showed that patients with MetS had a 41% higher chance of developing luminal A than those without MetS, and patients with a BMI≥30 Kg/m2 had an 80% higher chance of developing luminal B (HER-2+) than those with a BMI<30 Kg/m2. Moreover, women with a waist circumference higher than 88 cm had a 14 % lower chance of developing Luminal B (HER-2+) than those with a waist circumference less than 88 cm.
Conclusion: There was no difference in prognostic indicators and IHC profile in patients with and without MetS.

Background: Recurrent aphthous stomatitis (RAS) is the most common ulcerative disease that affects oral mucosa. The coating agents, topical analgesics, and topical steroids are usually used as treatment methods. Glycyrrhiza glabra has been used for RAS treatment based on its anti-inflammatory, antioxidant, and immunomodulatory properties. In this study, a systemic review on the therapeutic effect of topical licorice on RAS management was performed.
Methods: Science Direct, Scopus, Cochrane databases, PubMed Google Scholar, and ResearchGate were searched up to September 2021 to find all English randomized clinical trials studying the effect of G. glabra, or its compositions on RAS. Meta-analysis was not conducted because of data heterogeneity. Articles were reviewed qualitatively, and only those with a Jadad score ≥3 were included. Animal studies, in vitro, review papers, non-English papers, and case reports were excluded.
Results: Six studies with 314 subjects were included after screening. The result showed licorice has significant effects on RAS pain reduction, ulcer size, and healing time. Its effectiveness is related to its dose-dependent anti-inflammatory and antioxidant effects through several mechanisms. It also has antibacterial effects against Streptococci mutans and Porphyromonas gingivalis as another mechanism of action in RAS treatment. In addition, licorice can elevate the epidermal growth factor (EGF) level compared to the control group, which has an essential role in oral mucosal tissue integrity.
Conclusion: Licorice extract has been used in different dosage forms, including paste, patch, and mouthwash with concentrations of 1% or 5%.

Background: Plasma total cholesterol is considered a negative acute phase reactant. In various pathological conditions, such as trauma, sepsis, burns, and liver dysfunction, as well as post-surgery, serum cholesterol level decreases. This study aimed to investigate the role of lipid profiles in determining the probability of organ dysfunction after surgery.
Methods: This cross-sectional study included patients who underwent thoracoabdominal surgery and were admitted to the intensive care unit of Imam Reza Hospital in Tabriz, Iran, between October 2016 and September 2018. During the first two days of admission, blood samples were taken, and serum levels of total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), Low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), and albumin were measured. The relation between the changes in these laboratory markers and six organ functions including cardiovascular, respiratory, renal, central nervous system, hepatic, and hematologic, length of stay in the hospital and intensive care unit, mechanical ventilation duration, and vasopressor use were investigated. The independent t test was used to compare continuous variables. The association between different variables and organ dysfunction and mortality was evaluated by using logistic regression.
Results: The serum TC increased the risk of mortality (OR=1.09, 95%CI=1.06-1.11, P<0.001), renal dysfunction (OR=1.09, 95%CI=1.06-1.12; P<0.001), liver dysfunction (OR=1.07, 95%CI=1.03-1.10; P<0.001), respiratory dysfunction (OR=1.08, 95%CI=1.05-1.13; P<0.001). Moreover, LDL, HDL, and TG were found to be inversely related to mortality, organ dysfunction, length of stay in the hospital and intensive care unit, mechanical ventilation duration, and vasopressor use.
Conclusion: TC could be considered a risk factor for mortality, organ dysfunction, and clinical outcomes. On the other hand, LDL, HDL, and TG played a protective role in the patients' mortality, organ dysfunction, and clinical outcomes.

Background: Autophagy is a conservative mechanism for cell survival as the main response of cells to stress conditions. The present study aimed to assess the effect of docetaxel on the survival, fertilization, and expression of autophagy-related genes in vitrified oocytes.
Methods: The study was conducted in 2018 at the Stem Cells Technology Research Center, Shiraz University of Medical Sciences (Shiraz, Iran). Denuded oocytes were randomly selected and assigned to five groups, namely control (n=133), docetaxel (n=136), docetaxel+cryoprotectants (n=146), docetaxel+vitrification (n=138), and vitrification (n=145). The effect of vitrification on the expression of autophagy-related gene 5 (ATG5) and Beclin-1 was determined using a real-time polymerase chain reaction. Data were analyzed using SPSS software (version 26.0) and GraphPad Prism 9.
Results: Survival and fertilization rates in each experimental group were significantly reduced compared to the control group (P=0.001). After in vitro fertilization of oocytes, the 2-cell formation rate was significantly reduced in the docetaxel+vitrification and vitrification groups compared to the control and docetaxel groups (P=0.001 and P=0.001, respectively). Pre-incubation of oocytes with docetaxel reduced gene expression levels of Beclin-1 and ATG5 in the docetaxel+cryoprotectants and docetaxel+vitrification groups (P=0.001 and P=0.019, respectively). The expression level of these genes was also reduced in the docetaxel group compared to the control group (P=0.001).
Conclusion: Incubation of mouse metaphase II oocytes with docetaxel prior to vitrification reduced the expression of autophagy-related genes and increased survival and fertilization rates compared to untreated oocytes.

Background: Elevated low-density lipoprotein cholesterol (LDL-C) is a significant risk factor for cardiovascular diseases. LDL-C can be directly measured using various methods, but this requires expensive equipment. Currently, clinical laboratories estimate LDL-C based on Friedewald's formula (FF). We aimed to develop a modified formula based on directly measured LDL-C (D-LDL-C) values in a large population in Southern Iran and compare the results with various other estimation formulas.
Methods: The participants of this cross-sectional study were adults aged >18 years living in Southern Iran. Blood samples from 15,200 individuals were collected, and the measured lipid parameters were randomly divided into training (n=10,184) and validation (n=5,016) datasets. A new formula was developed using a linear regression model, and its accuracy was validated. Pearson's correlation and Cohen's kappa were used to determin the relationship between D-LDL-C and calculated LDL-C (C-LDL-C).
Results: The developed formula for the estimation of LDL-C was 0.857 total cholesterol (TC)-0.915 high-density lipoprotein cholesterol (HDL-C)-0.115 triglycerides (TG). Based on our proposed formula, for TG<150 and TG≥150 mg/dL, there was a significant correlation between mean values of D-LDL-C and C-LDL-C (r=0.985 and r=0.974, respectively). Compared to other formulas, C-LDL-C obtained from the proposed formula had the highest correlation with D-LDL-C. The agreement between D-LDL-C and C-LDL-C for TC<200, 200-239, and ≥240 mg/dL was 80.8%, 63.2%, and 67.4%, respectively, indicating a higher level of agreement than other formulas.
Conclusion: The new formula appears to be more accurate than FF when applied to the population of Southern Iran.
