Abstract
STUDY DESIGN Systematic review and meta-analysis. OBJECTIVE The aim of this study was to determine the prevalence of asymptomatic cervical spinal cord compression (CSCC) in individuals with lumbar spinal stenosis (LSS). METHODS A systematic electronic search was conducted in Medline, EMBASE, Scopus, and Web of Science without language restriction, with no starting date limit to June 8, 2023, to define the prevalence of asymptomatic CSCC in symptomatic LSS patients. Asymptomatic CSCC was defined based on radiographic studies. All types of studies were included in the review. Meta-analysis was performed on the reported prevalence of asymptomatic CSCC in LSS. RESULTS The database search yielded 10,272 articles. After a full-text review, five studies were included in the final review, comprising a total of 1043 cases. Two studies had a low risk for bias, two moderate, and one estimated to be high risk. The range of prevalence of asymptomatic CSCC in LSS in the five included studies was between 24% and 61%. Meta-analysis on the reported prevalence of asymptomatic CSCC patients with symptomatic LSS demonstrated that the random pooled prevalence was 35% (95% CI: 23 to 48). CONCLUSIONS Asymptomatic CSCC appears to occur in a high number of patients, with this study noting its presence in one-third of patients with LSS. Based on these findings, we strongly recommend that spine surgeons exercise particular caution during the positioning of patients who are undergoing surgery for lumbar stenosis. Furthermore, it is imperative to monitor individuals with symptomatic LSS closely for any potential signs of emerging myelopathy.

Abstract
Background There is controversial data on the effects of prebiotic, probiotic, or synbiotic supplementations on overweight/obesity indicators. Thus, we aimed to clarify this role of biotics through an umbrella review of the trials' meta-analyses. Methods All meta-analyses of the clinical trials conducted on the impact of biotics on overweight/obesity indicators in general populations, pregnant women, and infants published until June 2023 in PubMed, Web of Sciences, Scopus, Embase, and Cochrane Library web databases included. The meta-analysis of observational and systematic review studies without meta-analysis were excluded. We reported the results by implementing the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) flowchart. The Assessment of Multiple Systematic Reviews-2 (AMSTAR2) and Grading of Recommendations Assessment, Development, and Evaluation (GRADE) systems were used to assess the methodological quality and quality of evidence. Results Overall, 97 meta-analysis studies were included. Most studies were conducted on the effect of probiotics in both genders. Consumption of prebiotic: 8-66 g/day, probiotic: 104 -1.35×1015 colony-forming unit (CFU)/day, and synbiotic: 106-1.5×1011 CFU/day and 0.5-300 g/day for 2 to 104 weeks showed a favorable effect on the overweight/obesity indicators. Moreover, an inverse association was observed between biotics consumption and overweight/obesity risk in adults in most of the studies. Biotics did not show any beneficial effect on weight and body mass index (BMI) in pregnant women by 6.6×105-1010 CFU/day of probiotics during 1-25 weeks and 1×109-112.5×109 CFU/capsule of synbiotics during 4-8 weeks. The effect of biotics on weight and BMI in infants is predominantly non-significant. Prebiotics and probiotics used in infancy were from 0.15 to 0.8 g/dL and 2×106-6×109 CFU/day for 2-24 weeks, respectively. Conclusion It seems biotics consumption can result in favorable impacts on some anthropometric indices of overweight/obesity (body weight, BMI, waist circumference) in the general population, without any significant effects on birth weight or weight gain during pregnancy and infancy. So, it is recommended to intake the biotics as complementary medications for reducing anthropometric indices of overweight/obese adults. However, more well-designed trials are needed to elucidate the anti-obesity effects of specific strains of probiotics.

Abstract
STUDY DESIGN Systematic Reviews. OBJECTIVES To investigate predictors of surgical outcomes for mild Degenerative Cervical Myelopathy (DCM) by reviewing all related studies conducted at this point. METHODS An electronic search was carried out in PubMed, EMBASE, Scopus, and Web of Science until June 23, 2021. Full-text articles reporting surgical outcome predictors of mild DCM cases were eligible. We included studies with mild DCM which was defined as a modified Japanese Orthopaedic Association score of 15 to 17 or a Japanese Orthopaedic Association score of 13 to 16. Independent reviewers screened all the records, and discrepancies between the reviewers were solved in a session with the senior author. For risk of bias assessment, RoB 2 tool was used for randomized clinical trials and ROBINS-I for non-randomized studies. RESULTS After screening 6 087 manuscripts, only 8 studies met the inclusion criteria. Lower pre-operative mJOA scores and quality-of-life measurement scores were reported by multiple studies to predict better surgical outcomes compared to other groups. High-intensity pre-operative T2 magnetic resonance imaging (MRI) was also reported to predict poor outcomes. Neck pain before intervention resulted in improved patient-reported outcomes. Two studies also reported motor symptoms prior to surgery as outcome predictors. CONCLUSION Lower quality of life before surgery, neck pain, lower pre-operative mJOA scores, motor symptoms before surgery, female gender, gastrointestinal comorbidities, surgical procedure and surgeon's experience with specific techniques, and high signal intensity of cord in T2 MRI were the surgical outcome predictors reported in the literature. Lower Quality of Life (QoL) score and neck prior to surgery were reported as predictors of the more improved outcome, but high cord signal intensity in T2 MRI was reported as an unfavorable outcome predictor.

Abstract
Background and Aims Diabetic foot ulcers, a major cause of amputations in diabetics, could benefit from natural products as adjuncts to standard care, given the costs and adverse effects of typical therapies. This study aims to evaluate the short-term effects of dressing with Dermaheal ointment in the treatment of DFUs through a double-blinded randomized controlled clinical trial. Methods This double-blinded, placebo-controlled trial included 50 patients with Wagner's ulcer grade I or II, randomly assigned to Dermaheal and placebo groups (received standard treatment and placebo ointment). The ulcer site was dressed daily for four consecutive weeks with either Dermaheal or placebo ointment. Ulcer healing score (using DFU healing checklist), ulcer size with transparent ruler and largest dimension of ulcer, and pain severity using numerical pain rating score (were recorded at five-time points, including baseline, and on weeks 1, 2, 3, and 4). Also, ulcer healing status was investigated at the trial ended in November 2021. Results Both groups showed significant improvement in ulcer healing over 4 weeks (p time < 0.001), with more remarkable progress in the Dermaheal group (p group = 0.03). At the trial end, complete ulcer healing was also significantly higher in the Dermaheal group compared to the placebo group (56% vs. 12%, p = 0.002). Both groups exhibited a decrease in ulcer size (p time < 0.001). Considering the baseline ulcer size as a covariate, substantial changes in mean ulcer size were noted in the initial (p = 0.01), second (p = 0.001), third (p = 0.002), and fourth (p = 0.002) weeks of the intervention, showing a preference for the Dermaheal group. However, no significant between-group difference was observed in pain severity levels. Conclusion Dressing with Dermaheal as a topical treatment shows promise in improving healing and reducing the size of diabetic foot ulcers. Further research is needed to confirm these findings' long-term efficacy.

Abstract
INTRODUCTION This systematic review and meta-analysis aims to investigate the mutual impact of COVID-19 and psoriasis to inform clinical practice and future research. METHODS We followed the Preferred Reporting Items for Systematic Reviews and Meta-analysis protocol for systematic reviews and searched PubMed, Web of Science, Scopus, and Google Scholar until May 1, 2022. Eligibility criteria included full-text articles in English reporting COVID-19 treatment outcomes in psoriasis patients. Studies on animals, letters to editors, non-English studies, and studies with no access to full articles were excluded. Search results were screened and data were extracted by two groups of reviewers with any discrepancies resolved by the senior author. The risk of bias was assessed using ROBINS-I for nonrandomized studies. The hospitalization rate, Intensive Care Unit (ICU) admission rate, case fatality rate, odds ratios of COVID-19 infection and hospitalization rate in psoriasis patients were extracted and analyzed using random effects analysis to calculate pooled prevalence and odds ratios, as well as to explore heterogeneity. RESULTS We found 1980 records from four databases and included 20 studies after screening and removing duplicates. These studies evaluated 185,000 psoriasis patients and included eight retrospective cohort studies, one case-control study, three cross-sectional studies, and eight case series studies. The impact of the COVID-19 pandemic on psoriasis treatment and the outcome of COVID-19 infection in psoriasis patients receiving different forms of treatment were evaluated. The pooled data from included studies showed that the incidence rate of COVID-19 infection among psoriasis patients was 0.03% (confidence interval [CI]: 0.01-0.06), with a pooled odds ratio of 1.97 (CI: 0.69-5.60) compared to the general population. The hospitalization rate, ICU admission rate, and case fatality rate for psoriasis patients with COVID-19 were 0.17 (CI: 0.10-0.31), 0.06 (CI: 0.06-0.46), and 0.02 (CI: 0.01-0.04), respectively. Additionally, psoriasis patients receiving systemic nonbiologic therapy had a pooled odds ratio of 2.32 (CI: 1.18-4.57) for hospitalization compared to those using biologic agents. CONCLUSION Studies have shown that biologic therapy for psoriasis did not increase the risk of hospitalization due to COVID-19 infection and may have even offered some protection. Treatment adherence was higher in psoriasis patients receiving biologic therapies than those receiving conventional therapies. These findings suggest that psoriasis treatment did not negatively impact COVID-19 infection and that treatment could be continued on a case-by-case basis during the pandemic.

Abstract
Background Type 1 diabetes mellitus (T1DM) is a prevalent chronic disease among children and adolescents, necessitating effective self-monitoring of blood glucose (SMBG) levels. Understanding the determinants and factors influencing SMBG behavior is crucial for optimizing diabetes management in this population. Objectives This study aimed to investigate the frequency of SMBG and identify the determinants influencing factors in children and adolescents with T1DM. Methods This cross-sectional study was conducted in Tehran, Iran, and included 275 participants selected through simple random sampling from the Gabric Diabetes Education Association. The inclusion criteria comprised children and adolescents aged 3 - 18 years diagnosed with T1DM for at least 6 months who were using analog or neutral protamine Hagedorn (NPH) and regular insulin subcutaneously. Patients using insulin pumps were excluded. Data collection involved an online questionnaire covering demographic information (e.g., age, gender, educational status, and parental occupations) as well as clinical information (number of hypoglycemic episodes, hemoglobin A1C (HbA1C) levels, diabetes duration, insulin regimen, diabetes complications, glucose monitoring practices, hospitalizations, and behavioral characteristics). Statistical analyses, including descriptive statistics, correlation tests, and Poisson regressions, were performed using SPSS software (version 21). A significance level of P-value < 0.05 was considered statistically significant. Results The participants had a mean age of 10.00 ± 3.77 years, with 54.2% being males. Most of the participants (87.3%) were schoolchildren, and the mean age of diagnosis was 6.56 ± 3.73 years, with a mean duration of 44.72 ± 36.32 months. Anthropometric investigations revealed mean height, weight, and body mass index (BMI) values of 136.69 ± 21.11 cm, 37.45 ± 15.51 kg, and 18.31 ± 3.55 kg/m2, respectively. The majority of participants (93.5%) used insulin pens, and the mean daily insulin dosage was 35.34 ± 22.20 IU. Parents reported consistent glucose level monitoring in 64.7% of cases. The mean HbA1c level was 7.91 ± 1.58%. Factors such as the price and availability of glucometer strips influenced glucose level monitoring. In univariate analysis, only age and HbA1C levels showed a negative correlation; however, parents' consistent checking showed a positive correlation with the frequency of daily, weekly, or monthly glucose checking. Conclusions This study underscores the significance of SMBG in children and adolescents with T1DM. The findings emphasize the critical role of price and availability of glucometers and strips in achieving standard care for T1DM patients.

Abstract
BACKGROUND This study aims to evaluate Ki67 cut-off points for differentiating low and high-risk patients based on survival and recurrence and find the best Ki67 cut-off points in breast cancer patients undergoing adjuvant and neoadjuvant therapy using machine learning methods. PATIENTS AND METHODS Patients with breast cancer treated at 2 referral hospitals between December 2000 and March 2021 who had invasive breast cancer entered this study. There were 257 patients in the neoadjuvant group and 2139 in the adjuvant group. A decision tree method was used to predict the likelihood of survival and recurrence. The 2-ensemble technique of RUSboost and bagged tree were imposed on the decision tree method to increase the accuracy of the determination. 80 percent of the data was used to train and validate the model, and 20% was used as a test. RESULTS In adjuvant therapy breast cancer patients with Invasive ductal carcinoma (IDC) and Invasive lobular carcinoma (ILC) the cutoff points for survival were 20 and 10, respectively. For luminal A, luminal B, Her2 neu, and triple-negative adjuvant therapy patients' the cutoff points for survival were 25, 15, 20, and 20, respectively. For neoadjuvant therapy luminal A and luminal B group, survival cutoff points were 25 and 20, respectively. CONCLUSION Despite variability in measurement and cut-off points, the Ki-67 proliferation index is still helpful in the clinic. Further investigation is needed to determine the best cut-off points for different patients. The sensitivity and specificity of Ki-67 cutoff point prediction models in this study could further prove its significance as a prognostic factor.

Abstract
Background Publication bias is one of the most important biases in systematic reviews and meta-analyses. This bias occurs when the results of an article affect its publication, in other words positive or significant findings are more likely to be published than the other probable results. Previous studies have shown that publication bias has been a matter of concern in the meta-analysis and systematic reviews conducted in some medical fields. There is not a study that has evaluated the status of publication bias assessment in urology systematic reviews. We decided to assess the status of publication bias evaluation in systematic reviews and meta-analyses published in high impact urology journals. Methods This cross-sectional study was performed on 200 systematic reviews and meta-analysis published in four top urology journals based on their impact factor (European Urology, The Journal of Urology, BJU International and Prostate Cancer and Prostatic Diseases). Two independent reviewers performed data extraction about publication bias evaluation in included systematic reviews. Results From the 200 included studies only 65 (32.5%) evaluated the publication bias in the review process and 31 reviews had reported publication bias in their study. Visual inspection of a funnel plot was the most frequent method used for evaluation of publication bias (61 from 65, 93.85%); this method was used alone in 34 articles and in combination with other methods in 27 papers. Conclusion The present study confirms that publication bias was formally evaluated in a small number of reviews and meta-analysis published in urology journals, therefore, this may be a risk factor that could decrease the robustness of outcomes and results of these studies. It seems that there is an essential need for authors, reviewers, and editors to pay better attention to evaluation of publication bias besides reporting it based on the aforementioned reporting guidelines.

Abstract
STUDY DESIGN Scoping review. OBJECTIVES To identify a practical and reproducible approach to organize Quality of Care Indicators (QoCI) in individuals with traumatic spinal cord injury (TSCI). METHODS A comprehensive literature review was conducted in the Cochrane Central Register of Controlled Trials (CENTRAL) (Date: May 2018), MEDLINE (1946 to May 2018), and EMBASE (1974 to May 2018). Two independent reviewers screened 6092 records and included 262 full texts, among which 60 studies were included for qualitative analysis. We included studies, with no language restriction, containing at least 1 quality of care indicator for individuals with traumatic spinal cord injury. Each potential indicator was evaluated in an online, focused group discussion to define its categorization (healthcare system structure, medical process, and individuals with Traumatic Spinal Cord Injury related outcomes), definition, survey options, and scale. RESULTS A total of 87 indicators were identified from 60 studies screened using our eligibility criteria. We defined each indicator. Out of 87 indicators, 37 appraised the healthcare system structure, 30 evaluated medical processes, and 20 included individuals with TSCI related outcomes. The healthcare system structure included the impact of the cost of hospitalization and rehabilitation, as well as staff and patient perception of treatment. The medical processes included targeting physical activities for improvement of health-related outcomes and complications. Changes in motor score, functional independence, and readmission rates were reported as individuals with TSCI-related outcomes indicators. CONCLUSION Indicators of quality of care in the management of individuals with TSCI are important for health policy strategists to standardize healthcare assessment, for clinicians to improve care, and for data collection efforts including registries.

Abstract
H syndrome is a systemic inherited autosomal recessive histiocytosis, with characteristic cutaneous findings accompanying systemic manifestations and a most common genetic mutation (OMIM 612391) as SLC29A3. The term “H Syndrome” is representative of presentation with hyperpigmentation, hypertrichosis, hepatosplenomegaly, heart anomalies, hearing loss, hypogonadism, low height, and, occasionally, hyperglycemia. H syndrome is new and growing entity in medicine. This syndrome is not specific to a region or a nationality. There are very few treatment experiences on H Syndrome patients and most of them are unsatisfactory apart from hypertrichosis, which is able to treat almost permanently by hair removal lasers. Latest findings suggest that there is possibility of prevention of short stature or other cutaneous or systemic complications in this syndrome with earlier diagnosis and treatment. We searched Medline, Scopus, Web of Sciences, and Google Scholar, up to now and reviewed previous published papers with emphasis on treatment methods and its effects on certain common symptoms.

Abstract
Background and Objective Many biological activities and pharmacological usages have been revealed for the Cuscuta species. The present study aimed to assess the beneficial effects of Cuscuta on removing skin dark spots in healthy individuals, which is an important cosmetic concern, especially in women. Materials and Methods This prospective, interventional before-after trial was conducted in 70 healthy individuals without any evidence of skin or systemic disorders who presented for consultation on removing skin darkening. The Cuscuta extract was prepared and then assessed for plant quality control and lack of microbial contamination. The content of melanin at baseline and at 1 and 3 months after intervention was assessed using Dermacatch, an accurate skin colorimetric measurement tool. Results Comparison of the melanin content of the lesions and treated area to the surrounding normal area at baseline and at 1 month after treatment showed a significant reduction in melanin content from 519.61 ± 45.09 to 498.50 ± 39.35 (P < 0.001). This reducing trend remained significant from the first month to the third month after treatment (from 498.50 ± 39.35 to 483.53 ± 40.99, P < 0.001). This decreasing trend was persistent even after adjusting baseline characteristics including gender, age, and duration of skin lesions. Both patients and investigators had high satisfaction level with the anti-melanogenesis effect of Cuscuta extract. Conclusion Cuscuta extract is useful for removing hyperpigmented lesions and for skin lightening in healthy individuals.

Abstract
Interpersonal violence (IPV) is a major public health concern with a significant impact on physical and mental health. This study was designed to evaluate age-sex-specific IPV mortality trends and the assault mechanisms (firearm, sharp objects, and other means), at national and provincial levels, in Iran. We used the Iranian Death Registration System (DRS) and the population and housing censuses in this analysis. Spatio-temporal and Gaussian Process Regression methods were used to adjust for inconsistencies at the provincial level and to integrate data from various sources. After assessing their validity, all records were reclassified according to the International Classification of Diseases, 10th Revision (ICD-10). All ICD-10 codes were then mapped to Global Burden of Disease (GBD) 2013 coding. More than 700 individuals died due to IPV in 1990 and more than twice this number in 2015. The IPV mortality age-standardized rate, per 100,000, increased from 1.62 (95% Uncertainty Interval [UI] = [0.96, 2.75]) in 1990 to 1.81 [1.15, 2.89] in 2015. Among females, the age-standardized mortality rate at national level per 100,000 due to IPV was 1.27 [0.66, 2.43] in 1990 and decreased to 1.08 [0.60, 1.96] in 2015. Among males, the age-standardized mortality rate was 1.96 [1.25, 3.09] in 1990 rising to 2.54 [1.70, 3.82] in 2015. Data from provinces revealed that during the period of our study, Hormozgan province had the largest increase of IPV among females, and Fars province had the largest increase of IPV among males. Conversely, the largest decrease was detected in West Azarbaijan and Qom provinces in females and males, respectively. This study showed a wide variation in the incidence and trends of IPV in Iran by age, sex, and location. The study has provided valuable information to reduce the burden of IPV in Iran and a means to monitor future progress through repeated analyses of the trends.

Abstract
This article discusses the conversion of electrodeposited iodine to polyiodides within the nanopores of carbon electrodes that affect the performance of iodide electrolyte-based electrochemical cells. Here, carbon electrodes have been polarized in aqueous sodium iodide electrolyte to store charge in the form of solid iodine via highly reversible reaction (2I-⇌I2+2e-). The stored iodine within the pores interacts with free iodide ions present in the bulk electrolyte via comproportionation reactions leading to polyiodide (I3 - and I5 -) formations. By tuning the mass asymmetry of carbon electrodes in hybrid cells and using the in-situ Raman spectroscopy on positive battery electrode, we show the influence of iodine/polyiodides equilibrium shifts on the self-discharge and voltage rebounds during open circuit conditions. This study provides insights into the charging mechanisms of carbon electrodes for iodine-based hybrid supercapacitors and battery systems.

Abstract
H syndrome is a complex multi-organ disorder with autosomal recessive inheritance. The skin manifestations include early onset hyperpigmentation and hypertrichosis, followed by skin induration often diagnosed as scleromyxedema and morphea. There is no effective treatment. Our objective was to study the efficacy of mycophenolate mofetil in a patient with genetically confirmed H syndrome. We sought the genetic cause of H syndrome with whole-exome sequencing (WES) of the proband. Genome-wide homozygosity mapping (HM) provided additional evidence for causality of the variant suggested by WES. Here, we report a patient with characteristic clinical features of H syndrome, and the diagnosis was confirmed by identification of a homozygous SLC29A3 mutation (p.Gly437Arg). The patient was initially treated with prednisolone and cyclosporine, but after development of side-effects she was placed on mycophenolate mofetil. After the treatment with mycophenolate mofetil was initiated, resolution of hyperpigmentation was noted, and no new lesions developed during an 18-month follow-up period. Thus, mycophenolate mofetil could be considered as a safe and partially effective treatment of H syndrome.

Abstract
OBJECTIVE The WHO estimates the global incidence of death by drowning to be about 300 000 cases per year. The objective of this study was to estimate the trend in mortality due to drowning in all provinces of Iran in all age groups and both genders from 1990 to 2015. STUDY DESIGN The National and Subnational Burden of Diseases (NASBOD) project is a comprehensive project in Iran. It is based on the Global Burden of Disease study and includes novel methods to estimate the burden of diseases in Iran. METHODS This study used the results of the mortality rate due to drowning as part of NASBOD and investigated the causes behind the mortality rates. The data set recorded mortality rates by 19 age groups and two genders with the corresponding subnational pattern during the time period from 1990 to 2015. RESULTS The drowning mortality rate decreased in Iran from 1990 to 2015. From 1990 to 2015, the annual percentage change for males and females was -5.28% and -10.73%, respectively. There were 56 184 male and 21 589 female fatalities during the study period. The highest number of deaths was seen in 1993 with 4459, and the lowest number of fatalities was observed in 2015 with 903 deaths. CONCLUSION Our data showed a decline in drowning mortality in Iran from 1990 to 2015, but the rates and declines varied by province. Our findings are of great importance to health officials and authorities in order to further reduce the burden of drowning.

Abstract
OBJECTIVE This study aimed to investigate the association between dietary fat quality and menopausal symptoms. METHODS We carried out a cross-sectional study with 393 Iranian postmenopausal women. Dietary intakes and menopausal symptoms were assessed, using a validated food frequency questionnaire and a menopausal rating scale (MRS) questionnaire, respectively. Participants were divided into low and high total MRS and its domain scores. RESULTS Women in the highest quartiles of monounsaturated fatty acids (MUFA) had higher somatic symptoms compared with women in the lowest quartile (odds ratio [OR] 3.41; 95% confidence interval [CI] 1.17-9.95). Women in the highest quartiles of n-3 polyunsaturated fatty acids (PUFA) (OR 0.58; 95% CI 0.32-1.05), eicosapentaenoic acid (EPA) (OR 0.66; 95% CI 0.37-1.20), and n-3:n-6 PUFA ratio (OR 0.49; 95% CI 0.25-0.97) had lower somatic symptoms compared to the lowest quartiles. The OR for psychological symptoms decreased from the lowest to the highest quartiles of n-3 PUFA (OR 0.47; 95% CI 0.20-1.11) and n-3:n-6 PUFA ratio (OR 0.46; 95% CI 0.24-0.86). Higher intakes of EPA (OR 0.53; 95% CI 0.29-0.99) and docosahexaenoic acid (OR 0.51; 95% CI 0.27-0.95) were found to be related with fewer urogenital symptoms. CONCLUSION Consuming diets low in MUFA intake, but high in n-3 PUFA, and with a more favorable ratio of n-3:n-6 PUFA may be helpful for improving menopausal symptoms.

Abstract
To investigate whether 14-bp Ins/Del polymorphism in HLA-G gene is associated with the risk of chronic hepatitis B (CHB) infection. This study was performed on a total of 396 individuals including 199 CHB patients and 197 healthy subjects from a south-east Iranian population. We genotyped 14-bp Ins/Del polymorphism in the HLA-G gene using polymerase chain reaction method. The results of our study revealed that the HLA-G 14-bp deletion polymorphism was associated with a reduced risk of CHB at both allele and genotypic levels. The 14-bp Del allele and Ins/Del genotype were more frequent in control group than in CHB patients (37% vs 28% for Del allele with OR = 0.68 and p-value = .015; 73% vs 52% for Ins/Del genotype with OR = 0.43 and p-value = .001) and both were protective factors against CHB. However, no difference was found in the distribution of HLA-G 14-bp genotypes among subjects with varied levels of HBV DNA or hepatic enzymes (p > .05). Our findings, for the first time, suggest that the HLA-G 14-bp Ins/Del polymorphism may be a marker for genetic susceptibility to CHB infection.

Abstract
BACKGROUND Mutation of BRAF is a prevalent event in melanoma. Despite much attention to the role of BRAF mutation in melanoma, the status of BRAF protein expression and its significance in melanoma progression are unknown. OBJECTIVES We investigated the BRAF expression level in different stages of melanocytic lesions and evaluated its correlation with clinicopathological features and patient survival. METHODS Using tissue microarray, BRAF expression and its correlation with patient outcome was evaluated in 49 naevi samples and 370 patients with melanoma. We also evaluated the correlation of BRAF protein expression and V600E mutation using direct sequencing. RESULTS Compared with naevi samples, BRAF expression was remarkably increased in primary melanomas and further increased in metastatic melanomas (P = 1·8 × 10(-11) ). High BRAF expression was significantly correlated with thicker tumours, ulceration and higher American Joint Committee on Cancer stages (P = 1·5 × 10(-7) , 1·5 × 10(-5) and 3·6 × 10(-13) , respectively). In cases of primary melanoma, patients with high BRAF expression had significantly worse overall (P = 0·009) and disease-specific 5-year survival (P = 0·007). While there was a trend for higher prevalence of BRAF V600E mutation in patients with high BRAF protein expression, no significant correlation was observed between protein expression and BRAF mutation. Furthermore, univariate Cox regression analysis confirmed high BRAF protein expression as a strong risk factor for poor patient survival in primary melanoma [hazard ratio (HR) 2·08 for overall survival; HR 2·39 for disease-specific survival]. CONCLUSIONS Our data demonstrate that BRAF protein expression is significantly increased during melanoma progression. In addition, we revealed a novel prognostic value for BRAF protein expression in primary melanoma as it is significantly correlated with poor patient survival.

Abstract
BACKGROUND Safety of blood donor is an important issue for a recipient of blood so all blood donors are to screened for viral such as HBV, HCV, and HIV. Nevertheless, infections sometime occur by blood and its products. OBJECTIVE Because we haven't got any awareness about isolated Hbc Ab from a blood donor who presented of occults B hepatitis which can transmit infection to blood recipient, we decided to evaluate HbcAb in a blood donor in this province. MATERIALS AND METHODS This is a cross-sectional study on a blood donor in Sistan-Balutuestan province in southeast of Iran in 2010. All individuals referred for blood donation recruited to this. After consent demographic data was recorded from each case, 5 ml blood sample was drawn and centrifuged to separate out the serum and then HbsAb, HbcAb was assayed. Data analyzed by SPSS 16 and frequency, chi- square test, and Fisher exact test was used and if P > 0.05 it was accented as significant association. RESULT All individuals were men with age 55 10.5 years. The number of people who had free job was 149 (34.6%) and the number of people whose education level was diploma was 159 (36.9%). About 423 (98.1%) lived in urban areas. The mean weight of men was 76.6 13.7; about 259 (60.1%) men were married. A total of 22 (5.1%) had a positive smoking history. HBc Ab was positive in 87 (20.2%). Nearly all people had HBsAb titer more than 10 IU/L. CONCLUSION This study showed that some of the blood donors had isolated HbcAb positive therefore we recommend HbcAb screening for blood donation.

Abstract
BACKGROUND Cutaneous melanoma is a life-threatening skin cancer because of its poorly understood invasive nature and high metastatic potential. This study examines the importance of eukaryotic translation initiation factor 5A2 (EIF5A2) in melanoma pathogenesis. METHODS We examined EIF5A2 expression in 459 melanocytic lesions using tissue microarray. In addition, melanoma cell lines were subjected to invasion and cell proliferation assays, zymography, FACS and real-time PCR to investigate the role of EIF5A2 in cancer progression. RESULTS Positive EIF5A2 staining increased from dysplastic naevi to primary melanomas (PMs; P=0.001), and further increased in metastatic melanomas (P=0.044). Eukaryotic translation initiation factor 5A2 expression was correlated with melanoma thickness (P<0.001) and was inversely correlated with the 5-year survival of PM patients especially those with tumour ≤2 mm thick. Strikingly, none of the latter died within 5 years in EIF5A2-negative staining group. Cox regression analysis revealed that EIF5A2 is an independent prognostic marker. Further, we found that EIF5A2 is a novel downstream target of phosphorylated Akt. Both melanoma cell invasion and MMP-2 activity increased and decreased with EIF5A2 overexpression and knockdown, respectively. CONCLUSION We for the first time showed that EIF5A2, as a target of PI3K/Akt, promotes melanoma cell invasion and may serve as a promising prognostic marker and a potential therapeutic target for melanoma.

Abstract
BACKGROUND Hepatitis B virus (HBV) infection is a major risk factor of cirrhosis and hepatocellular carcinoma affecting billions of people globally. Since information on its prevalence in general population is mandatory for formulating effective policies, this population based serological survey was conducted in Sistan and Baluchistan, where no previous epidemiological data were available. METHODS Using random cluster sampling 3989 healthy subjects were selected from 9 districts of Sistan and Baluchistan Province in southeastern Iran. The subjects' age ranged from 6 to 65 years old. Serum samples were tested for HBcAb, HBsAg. Screening tests were carried out by the third generation of ELISA. Various risk factors were recorded and multivariate analysis was performed. RESULTS The prevalence of HBsAg and HBcAb in Sistan and Baluchistan was 3.38% (95% CI 2.85; 3.98) and 23.58% (95% CI 22.29; 24.93) respectively. We found 8 cases of positive anti-HDV antibody. Predictors of HBsAg or HBcAb in multivariate analysis were age, marital status and addiction. CONCLUSION The rate of HBV infection in Sistan and Baluchistan was higher than other parts of Iran. Approximately 25% of general population in this province had previous exposure to HBV and 3% were HBsAg carriers. Intrafamilial and addiction were major routes of HBV transmission in this province.

Abstract
We investigated the correlations between the in vivo-in vitro induction of 2'-5' oligoadenylate synthetase (2-5A synthetase) by IFN-alpha in cells isolated from patients with low-grade nodular non-Hodgkin's lymphoma (NHL) and subsequent clinical responses of these patients to IFN-alpha therapy. Eleven patients were treated daily with 9 x 10(6) U of IFN-alpha 2a in a phase II trial. After an eight week treatment, four patients achieved complete remission, one a partial response, one a minor response, and five failed to respond. Basal levels of 2-5A synthetase in lymph node tumor B cells and peripheral blood mononuclear cells (PBMC) isolated before therapy differed from patient to patient and were significantly lower than in PBMC from healthy donors (P less than 0.03). In vivo single injections of 9 x 10(6) U IFN-alpha 2a induced the 2-5A synthetase in PBMC from all patients to various degrees without quantitative relation to the clinical responses. Injection of a tenfold lower dose resulted in effects of similar extent in most cases. In vitro, IFN-alpha 2a induced the 2-5A synthetase in lymph node tumor B cells isolated before therapy, and the degree of induction was significantly higher in patients who proved to respond to therapy than in patients who displayed no or minor responses (P less than 0.013). This indicates that, in nodular NHL, the 2-5A synthetase assay may have some predictive value for responsiveness to IFN-alpha therapy.
