Background:
Sinonasal malignancies are a rare group of head and neck cancers. We aimed to report the oncological outcomes based on histological types in patients who underwent radiotherapy.
Materials and Methods:
In this single-institution study, we retrospectively retrieved and analyzed data of patients with sinonasal carcinomas who underwent radiotherapy during 2011–2016 as part of their treatment. The 3-year rate of local, regional, and distant recurrences, and overall survival were evaluated according to the histological type.
Results:
A total of 28 patients were evaluated in this study, the majority of whom were male (60%). Squamous cell carcinoma (SCC), adenoid cystic carcinoma (ACC), and adenocarcinoma (ADC) were found in 15 patients (53.5%), 8 (28.5%), and 5 (18%), respectively. The highest rates of local and regional recurrences were observed in ACC and SCC, respectively. Distant recurrences were numerically more common in ADC. The 3-year OS was 48%, 50%, and 73% in SCC, ADC, and ACC, respectively.
Conclusion
Different histopathologies of sinonasal cancer seem to have different patterns of failure, and this may be considered in the treatment approach.

BACKGROUND:
This systematic and meta-analysis review aimed to provide an updated estimate of the prevalence of ever and current cigarette smoking in women, in geographic areas worldwide, and demonstrate a trend of the prevalence of smoking over time by using a cumulative meta-analysis.
METHODS:
Following PRISMA guidelines, we conducted a systematic review and meta-analysis of studies published on the prevalence of ever and current cigarette smoking in women. We searched PubMed, Web of Science (ISI), Scopus, and Ovid from January 2010 to April 2020. The reference lists of the studies included in this review were also screened. Data were reviewed and extracted independently by two authors. A random effects model was used to estimate the pooled prevalence of ever and current cigarette smoking in women. Sources of heterogeneity among the studies were determined using subgroup analysis and meta-regression.
RESULTS:
The pooled prevalence of ever and current cigarette smoking in women was 28% and 17%, respectively. The pooled prevalence of ever cigarette smoking in adolescent girls/students of the school, adult women, pregnant women, and women with the disease was 23%, 27%, 32%, and 38%, respectively. The pooled prevalence of ever cigarette smoking in the continents of Oceania, Asia, Europe, America, and Africa was 36%, 14%, 38%, 31%, and 32%, respectively.
CONCLUSIONS
The prevalence of cigarette smoking among women is very high, which is significant in all subgroups of adolescents, adults, and pregnant women. Therefore, it is necessary to design and implement appropriate educational programs for them, especially in schools, to reduce the side effects and prevalence of smoking among women.

Background: Auraptene is a simple coumarin that exhibits multiple protective activities in the
brain. Alzheimer’s disease is a complex, multifactorial, and progressive neurodegenerative disease.
Microinjection of the β-amyloid peptide (Aβ) into the hippocampus of rat has been recognized as a
reliable and stable animal model of Alzheimer’s disease, which mimics the memory deficits. In the
present study, the memory enhancing effects of auraptene were studied in rats that Aβ was injected
into their hippocampus to create a model of Alzheimer’s disease. Methods: Different doses of
auraptene (5, 10 and 25 mg/kg) were administered intraperitoneally to male Wistar rats. The spatial
memory performance was tested by Morris water maze after Alzheimer`s induction. The hippocampal
expression of pro-apoptotic Bax and anti-apoptotic Bcl-2 proteins were calculated for evaluating the
neuroprotective and anti-apoptotic effects of Auraptene in the brain tissue. Results: In comparison
with the control group, auraptene significantly decreased the escape latency time in the treated rats. In
addition, auraptene increased the percentage of time spent and traveled pathway in the target quadrant.
Molecular data showed that auraptene attenuated the Bax/Bcl-2 ratio in the hippocampus of rats.
Conclusion: This study demonstrated the memory enhancing effect of Aur after Aβ injection, which
could be through inhibiting the apoptotic pathways in the hippocampus of rats.

OBJECTIVES: Different factors are responsible for the silent epidemic of diabetes mellitus in developing and developed countries. This study aimed to determine the role of demographic factors, lipid profile, family history (the estimation of genetic association) and anthropometric factors on diabetes onset. METHODS: Data from the enrolment phase of the Tabari Cohort study was applied for this study and included 10,255 participants aged between 35–70 years. Anthropometric variables were measured by trained staff using standard tools. Blood specimens were collected for lipid profile and blood glucose measurements. Data analyses were performed using SPSS version 24, with univariate and multivariate logistic regression. RESULTS: The prevalence of diabetes mellitus was estimated to be 17.2% in the cohort population, 15.6% in men, and 18.3% in women. The adjusted odds ratios (95% confidence intervals) for age groups 40–49, 50–59 and over 60 were 2.58 (2.20–3.69), 5.80 (4.51–7.48) and 8.72 (6.67–11.39), respectively. In addition, the odds ratios (95% confidence intervals) for 2 (or more), and 1 affected family member were 4.12 (3.55–4.90) and 2.34 (2.07–2.65), respectively. Triglyceride concentrations more than 500, and abnormal high-density lipoprotein levels increased the odds of diabetes mellitus by 3.29- and 1.18-fold, respectively. CONCLUSION: The current study showed that old age and a family history were strong predictors for diabetes mellitus.

In this study, an attempt was made to develop bi-functional constructs serving both as scaffolds and potential delivery systems for application in neural tissue engineering. The constructs were prepared in two steps. In the first step, the bulks of poly (L-lactic acid) (PLLA) in 1, 4-dioxane/water (87:13) were fabricated using liquid-liquid thermally induced phase separation technique. In the next step, the prepared bulks were coated with chitosan nanoparticles produced by two different techniques of ultrasonication and ionic gelation by grafting-coating technique. In ultrasonication technique, the chitosan solution (2 mg/mL) in acetic acid/sodium acetate buffer (90:10) was irradiated by an ultrasound generator at 20 kHz and power output of 750 W for 100 s. In ionic gelation technique, the tripolyphosphate in water solution (1 mg/mL) was added to the same chitosan solution. The physicochemical properties of the products were characterized by Scanning Electron Microscopy, Attenuated Total Reflection Fourier Transform-Infrared, liquid displacement technique, contact angle measurement, compressive and tensile tests, as well as zeta potential and particle size analysis using dynamic light scattering. Moreover, the cell proliferation and attachment on the scaffolds were evaluated through human glioblastoma cell line (U-87 MG) and human neuroblastoma cell line [BE (2)-C] culture respectively. The results showed that the samples coated with chitosan nanoparticles prepared by ultrasonication possessed enhanced hydrophilicity, biodegradation and cytocompatibility compared with pure PLLA and PLLA coated with chitosan nanoparticles prepared by ionic gelation. This study suggests successful nanoparticles-scaffold systems which can act simultaneously as potential delivery systems and tissue engineering scaffolds.

PURPOSE: The aim of this study was to compare the penile cuff test (PCT) and standard pressure-flow study (PFS) in patients with bladder outlet obstruction. MATERIALS AND METHODS: A total of 58 male patients with moderate to severe lower urinary tract symptoms (LUTS) were selected. Seven patients were excluded; thus, 51 patients were finally enrolled. Each of the patients underwent a PCT and a subsequent PFS. The sensitivity (SE), specificity (SP), positive predictive value (PPV), negative predictive value (NPV), and likelihood ratio were calculated. Chi-square and Fisher exact test were used to evaluate relationships between PCT results and maximal urine flow (Qmax); a p<0.05 was considered statistically significant. RESULTS: The mean (±standard deviation) age of the study group was 65.5±10.4 years. Overall, by use of the PCT, 24 patients were diagnosed as being obstructed and 27 patients as unobstructed. At the subsequent PFS, 16 of the 24 patients diagnosed as obstructed by the PCT were confirmed to be obstructed, 4 were diagnosed as unobstructed, and the remaining 4 patients appeared equivocal. Of the 27 patients shown to be unobstructed by the PCT, 25 were confirmed to not be obstructed by PFS, with 13 equivocal and 12 unobstructed. Two patients were diagnosed as being obstructed. For detecting obstruction, the PCT showed an SE of 88.9% and an SP of 75.7%. The PPV was 66.7% and the NPV was 93%. CONCLUSIONS: The PCT is a beneficial test for evaluating patients with LUTS. In particular, this instrument has an acceptable ability to reject obstruction caused by benign prostatic hyperplasia.
