Background: Adhesion of Candida to host cell receptors, hemolysin production, and proteinase activity are assumed as principal virulence factors and infection establishment. These virulence factors are essential for colonization, biofilm formation, and attack on the host cells. Materials and Methods: A total of 97 Candida albicans isolates obtained from gastroesophageal lesions and urinary tract infections were included in the study. Adhesion assay, proteinase activity, and hemolysin production were measured. Statistical analysis was performed using the independent t-test and Chi-square test to compare quantitative and qualitative data between the two groups. Results: The adherence ability to the buccal epithelial cells was the same in the two groups. Proteinase activity was seen in all clinical isolates. Hemolytic activities were not statistically significant in the two groups. Conclusion: Our results recommend that the pathogenicity of C. albicans in the mucous membranes cannot be connected to the infected site.

At a time when the COVID-19's second wave is still picking up in countries like India, a number of reports describe the potential association with a rise in the number of cases of mucormycosis, commonly known as the black fungus. This fungal infection has been around for centuries and affects those people whose immunity has been compromised due to severe health conditions. In this article, we provide a detailed overview of mucormycosis and discuss how COVID-19 could have caused a sudden spike in an otherwise rare disease in countries like India. The article discusses the various symptoms of the disease, class of people most vulnerable to this infection, preventive measures to avoid the disease, and various treatments that exist in clinical practice and research to manage the disease.

Background: Breast cancer is among the most common malignancies in women around the world. There is evidence of high prevalence of serum/blood Vitamin D deficiency in Iranian women. Considering the multitude of factors that may be involved in the prognosis and lifespan of breast cancer patients, this study investigated the level of Vitamin D in Iranian patients with nonmetastatic breast cancer. Materials and Methods: This cross-sectional study was carried out on 214 women diagnosed with breast cancer, who were referred to the radio-oncology department. Serum Vitamin D level of the patients was measured. Prognostic factors were determined based on demographic and pathological characteristics. The results were analyzed using descriptive statistics tests, Chi-square, one-way analysis of variance, Kaplan–Meier, and Cox regression model in SPSS v22. For all cases, the significance level was considered to be P < 0.05. Results: The total mean of 25-hydroxyvitamin D serum level was 25.15 ± 17.68 ng/ml. There was no significant relationship between levels of Vitamin D with disease stage, tumor size, tumor grade, estrogen receptor, progesterone receptor, and Human epidermal growth factor receptor 2 (P > 0.05). The mean survival time was 5 years and 45 days. Conclusion: No relationship was found between serum Vitamin D levels and the factors affecting the prognosis of nonmetastatic breast cancer. The Cox analysis showed that the survival time was not influenced by Vitamin D as a prognosis factor.

Background: Depression is one of the most common neuropsychiatric symptoms in Parkinson's disease (PD). There is little evidence to guide depression treatment in these patients. The aim of this study was to compare citalopram and pramipexole in reducing depressive symptoms in patients with PD. Materials and Methods: In the present 8-week randomized trial, we compared the efficacy of pramipexole versus citalopram in the treatment of depression in PD patients. For this purpose, 44 PD patients with depression randomly received open-label oral citalopram tablets or pramipexole and their depression, quality of life, and daytime sleepiness scores were evaluated at baseline and after the 8-week trial period. Results: The median age of the patients was 64 years, and about 85% of them were male in both groups. The Beck Depression Inventory score, Parkinson's disease summary index (PDSI), and Epworth Sleepiness Scale were significantly decreased (P < 0.05) in both citalopram and pramipexole groups throughout this period and without significant difference (P > 0.05) between these two groups, except for PDSI score which showed significant improvement in pramipexole group compared with citalopram group (P < 0.0001, r = 0.319). There were neither serious adverse effects nor treatment discontinuation due to the adverse effects. Conclusion: The results indicated that both citalopram and pramipexole were effective in the alleviation of depression and improving the quality of life in PD patients; however, pramipexole was seemed to be slightly more beneficial on quality of life in these patients. Therefore, pramipexole seems to be an effective treatment for depression in addition to its benefits for motor symptoms of PD patients.

Background: The main composition of intestinal microbiota in nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) patients has not yet been elucidated. In this, case-control study, we identified differences of intestinal microbiota in male patients with NAFLD, presumed NASH, and healthy controls. Materials and Methods: We compared gut microbial composition of 25 patients with NAFLD, 13 patients with presumed NASH, and 12 healthy controls. Demographic information as well as clinical, nutritional, and physical activity data was gathered. Stool and blood samples were collected to perform the laboratory analysis. The taxonomic composition of gut microbiota was assessed using V4 regions of microbial small subunit ribosomal Ribonucleic acid genes sequencing of stool samples. Results: Firmicutes, Actinobacteria, and Bacteroidetes were the most frequently phyla in all groups. Our results revealed that Veillonella was the only genus with significantly different amounts in presumed NASH patients compared with patients with NAFLD (P = 2.76 × 10⁻⁶, q = 2.07 × 10⁻⁴, logFC = 5.52). Conclusion: This pilot study was the first study to compare gut microbial composition in patients with NAFLD and presumed NASH in the Middle East. Given the potential effects of gut microbiota on the management and prevention of NAFLD, larger, prospective studies are recommended to confirm this study's findings.

In recent years, some studies have evaluated the epidemiologic factors associated with breast density. However, the variant and inconsistent results exist. In addition, breast density has been proved to be a significant risk factor associated with breast cancer. Our review summarized the published studies and emphasized the crucial factors including epidemiological factors associated with breast density. In addition, we also discussed the potential reasons for the discrepant results with risk factors. To decrease the incidence and mortality rates for breast cancer, in clinical practice, breast density should be included for clinical risk models in addition to epidemiological factors, and physicians should get more concentrate on those women with risk factors and provide risk-based breast cancer screening regimens.

Background: The aim of the present study was to investigate the effects of melatonin supplementation along with nonsurgical periodontal therapy (NSPT) in patients with type 2 diabetes mellitus (T2DM) and chronic periodontitis (CP). Materials and Methods: The present study was a double-blind clinical trial. Fifty diabetic patients with periodontitis were randomly allocated to control (n = 25) and intervention groups (n = 25). Two tablets of 250 mg melatonin (6 mg net melatonin) or placebo were received by the intervention or control groups once a day for 8 weeks. Fasting blood glucose (FBG), glycosylated hemoglobin levels (HbA1c), lipid profile, systolic and diastolic blood pressure (SBP and DBP), anthropometric indices including weight, waist and hip circumference (WC and HC), and body mass index (BMI) were measured in patients at the beginning and end of the intervention. Results: Forty-four patients (22 patients in each group) completed the study. In the intervention group, a significant reduction was observed in HbA1c (P = 0.004), weight, BMI, WC, HC (all P < 0.001), DBP (P = 0.017), and SBP (P = 0.006). The high-density lipoprotein-cholesterol was significantly increased in the intervention group after the intervention (P = 0.007). Moreover, after the adjustment of confounding factors, the mean changes of HbA1c (mean difference: −1.30, confidence interval [CI]: −2.41–−0.19, P = 0.02), weight (mean difference: −3.90, CI: −5.30–2.50, P < 0.001), WC (mean difference: −1.37, CI: −2.19–−0.55, P = 0.002), BMI (mean difference: −1.41, CI: −1.92–−0.89, P < 0.001), HC (mean difference: −3.55, CI: −4.74–−2.35, P < 0.001), and SBP (mean difference: −1.24, CI: −2.41–−0.06, P = 0.03) improved significantly in the intervention group by comparison with the control group. No side effects were reported during the study. Conclusion: The adjunct therapy of NSPT and melatonin may be useful in controlling the glycemic index, lipid profile, BP, and weight in T2DM with CP.

Background: Violence Risk Screening Tool-10 (V-Risk-10) is one of the few instruments available for violence risk assessment in patients with a psychiatric diagnosis. The present study aimed to validate the Persian version of this instrument in patients admitted to the psychiatric ward. Materials and Methods: Eighty patients referred to a psychiatric hospital were enrolled in this cross-sectional methodological study. In the initial phase, seven senior psychiatry residents rated 20 cases independently at the time of their admission and total scale and subscale reliability were examined. Intraclass correlation coefficients were used to assess the inter-rater reliability. After initial confirmation of V-RISK-10 reliability, a senior psychiatry resident assessed 80 patients with V-RISK-10 in the emergency room. The incident of violent behaviors was recorded during the patients' admission period. The receiver operator characteristics curve (ROC-curve) analysis was used to measure the predictive accuracy of the instrument. The convergent validity was assessed by comparing V-RISK-10 scores between the three risk categories and the three outcome recommendations according to clinicians' overall clinical judgment. Results: A Cronbach's alpha coefficient was 0.99 for the total scale. During the research period, 47.5% of patients demonstrated various degrees of aggression and violent behavior. The ROC area under the curve was 0.89 (P < 0.001) with 87% sensitivity, 69% specificity, 72% positive predictive value, and 85% negative predictive value at the cutoff point of 8.5. Conclusion: Results indicate that the Persian version of V-Risk-10 is a reliable and valid screening tool for violence risk in patients who are admitted into psychiatric wards.

Background: The present study aimed at determining and comparing the prognostic value and the relationship of neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios (PLRs) with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Materials and Methods: The present case–control study was performed on 100 chronic obstructive pulmonary disease patients and 100 healthy subjects (controls). Age, gender, and laboratory results of complete blood count tests including lymphocyte count, neutrophil count, platelet count, hemoglobin level, neutrophil-to-lymphocyte ratio (NLR), PLR, C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) were obtained from the patient report and then recorded. The mentioned information was also completed for the control group. Following hospitalization, the patients that were discharged with clinically stable general status were re-examined, and the aforementioned laboratory information was rerecorded. Results: The results of the present study revealed that NLR with the sensitivity and specificity of 83.00% (74.2%–89.8%) and 93.00% (86.1%–97.1%) (cutoff value of 2.3), PLR with the sensitivity and specificity of 56.00% (46.0%–66.3%) and 83.00% (74.2%–89.8%) (cutoff value of 135.8), white blood cell (WBC) with the sensitivity and specificity of 69.00% (57.7%–77.8%) and 78.00% (68.6%–85.7%) (cutoff value of 8.5 × 103 μl), ESR with the sensitivity and specificity of 84.00% (75.3%–90.6%) and 99.00% (94.6%–100.0%) (cutoff value of 7.8), and CRP with the sensitivity and specificity of 52.00% (41.8%–62.1%) and 81.00% (71.9%–88.2%) (cutoff value of 1.9), respectively, had a significant prognostic value of AECOPD (P < 0.001). In addition to NLR had higher area under the curve (AUC) than PLR, WBC, and CRP. Therefore NLR had a better diagnostic value than the above three markers (P < 0.001). ESR also has higher AUC levels compared to PLR, WBC, and CRP and has a statistically better diagnostic value than them (P < 0.001), but did not differ significantly from ESR (difference between AUC: 0.02; P = 0.059). Conclusion: According to the results of the current study, NLR and PLR had a significant direct relationship with the two main markers of ESR and CRP, and both ratios had a significant prognostic value in AECOPD.

Background: The inflammatory and metabolic responses to mushroom in type 2 diabetes mellitus (T2DM) are unknown. The study aimed to evaluate the effect of Hot Air-dried White Button Mushroom (HAD-WBM) powder on glycemic status, lipid profile, inflammatory markers, and total antioxidant capacity (TAC) in T2DM patients. Materials and Methods: This randomized controlled trial was conducted at Golestan Hospital, Ahvaz, Iran. Eligible patients were adults aged 20–50 with Type 2 diabetes. Patients were assigned to each group using a randomized block design with block randomization (n = 22, in each group). Randomization was performed by an assistant and group allocation was blinded for the investigator and participants. The intervention and control groups received 16 g/day HAD-WBM or cornstarch powder for 8 weeks. The primary outcomes of interest were fructosamine, fasting blood sugar (FBS), insulin, homeostatic model assessment for insulin resistance, and secondary outcomes were triglyceride, low-density lipoprotein (LDL), high-density lipoprotein, very-LDL, cholesterol, high-sensitivity C-reactive protein (hs-CRP), interleukin 6 (IL-6), and TAC. Results: After 8 weeks, a significant decrease was observed in fructosamine (−0.228 ± 0.36 vs. 0.03 ± 0.38; P = 0.02) and LDL (−13.05 ± 20.67 vs. 0.81 ± 21.79; P = 0.04) in the HAD-WBM group compared to the control group. No significant changes were observed in fasting insulin and FBS between the two groups. However, a significant within-group reduction (−28.00 ± 42.46; P = 0.006) was observed for FBS in the HAD-WBM group. In the HAD-WBM group, insulin resistance reduced significantly at the end of the study (From 4.92 to 3.81; P = 0.016), but it was not significantly different between the two groups. There was no significant difference in TAC, hs-CRP, and IL-6 between the two groups. Conclusion: Considering the results of this study about the beneficial effects of HAD-WBM on the improvement of glycemic indices and LDL in T2DM patients, it is recommended that HAD-WBM could be used to control T2DM.
