Abstract
Background: Telomeres are involved in chromosomal stability, cellular immortality and tumorigenesis. Human
telomerase reverse transcriptase (TERT) is essential for the maintenance of telomere DNA length. Recently, a variable
tandem-repeats polymorphism, MNS16A, located in the downstream region of the TERT gene, was reported to have
an effect on TERT expression and telomerase activity. Previous studies have linked both relative telomere length
(RTL) and TERT variants with cancer. Therefore, we evaluated associations between RTL, TERT gene polymorphisms
(hTERT, rs2735940 C/T and MNS16A Ins/Del) and risk of childhood acute lymphoblastic leukemia (ALL) in an Iranian
population. Methods: RTL was determined by a multiplex quantitative PCR-based method, and variants of the hTERT,
rs2735940 C/T and MNS16A Ins/Del, were genotyped by amplification refractory mutation system PCR (ARMS-PCR),
and PCR, respectively. Results: Our results indicated that RTL was shorter in ALL patients (1.53±0.12) compared to
the control group (2.04±0.19) (P=0.029). However, no associations between hTERT gene variants or haplotypes and
the risk of childhood ALL were observed (P>0.05). Also hTERT polymorphisms were not associated with RTL or
patient clinicopathological characteristics, including age (P=0.304), sex (P=0.061) organomegally (P=0.212) CSF
involvement (P=0.966) or response to treatment (P=0.58). Conclusions: We found that telomere attrition may be
related to the pathogenesis of childhood ALL, irrespective to TERT variants.

Abstract
Intracranial haemorrhage (ICH) is the most dreadful complication, and the main cause of death among patients with rare bleeding disorders (RBD) and prenatal diagnosis (PND) is a preventative lifesaving program. A total of 39 PNDs were reported in the literature through a search on PubMed, EMBASE, SCOPUS and Web of Science databases, most often for congenital factor (F) XIII and FVII deficiencies and rarely in FX, FV deficiencies and afibrinogenemia. The main cause to request a PND is ICH and related morbidity and mortality. Different molecular methods including direct sequencing and linkage analysis as well as polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) for a specific mutation are the most common used methods for PND, while factor assay and combination of molecular and factor assay also were used. In this research, 7 severely affected foetuses were identified during PND including 3 foetuses with FXIII deficiency, 3 with FVII deficiency and 1 with FX deficiency. Out of these 7 cases, intrauterine ICH occurred in 1 case with FXIII deficiency, 1 was electively aborted and 1 case with severe FVII deficiency received intrauterine factor transfusion. Postdelivery ICH was reported for 1 patient with severe FVII deficiency within the first month of life. All other pregnancies were uneventful.

Abstract
Background: Glanzmann Thrombasthenia (GT) is a rare autosomal disease. HPA (Human Platelet Alloantigen) is a surface polymorphic alloantigen of platelets. This study was intended to investigate and compare the polymorphism of HPA-1 and HPA-5 genes in two groups of GT patients, with and without resistance to platelet and recombinant factor VII therapy. Materials and Methods: This case control study was performed on GT patients (n=16) with resistance to platelet therapy and recombinant factor VII and control group of GT patients (n=16) without resistance to platelet therapy and recombinant factor VII. The consent form was completed by each patient. Gene polymorphisms of HPA-1 and HPA-5 were investigated using SSP-PCR, and the obtained data were analyzed using statistical software SPSS16.0. Results: The results indicated no significant relationship between the studied genes and their resistance to platelet therapy and recombinant factor VII. The frequencies of HPA-1 genotype a/a were 98% and 94% in patient and control groups, respectively. The frequency of allele b was found to be less than allele a. The value of this allele was 4% in patient group and 1% in control group. In addition, the HPA-5a/a (98%) was the most frequent alloantigen?? (check it) in both groups. Seven percent (7%) of the patients had the HPA-5a/b genotype, and the HPA-5b/b was found to be absent in these individuals. Conclusion: According to the results obtained, it could be concluded that these genes play no role in resistance to platelet therapy.

Abstract
The present case-control study was conducted on 110 children with acute lymphoblastic leukemia (ALL) and 120 healthy children to determine the impact of polymorphisms in paired-box gene 8 (PAX8) antisense RNA 1 (PAX8-AS1), namely rs4848320 C>T, rs6726151 T>G and rs1110839 G>T, on ALL risk. Genotyping was performed through the polymerase chain reaction-restriction fragment length polymorphism method. The findings indicated that the rs4848320 variant increased the risk of ALL in codominant [CT vs. CC: odds ratio (OR)=2.13, 95% confidence interval (CI)=1.16-3.90, P=0.014; and TT vs. CC: OR=2.21, 95% CI=1.03-4.74, P=0.041], dominant (CT+TT vs. CC: OR=2.15, 95% CI=1.22-3.81, P=0.009,) and allele (T vs. C: OR=1.55, 95% CI=1.07-2.25, P=0.024) inheritance models. The rs6726151 variant significantly increased the risk of ALL in codominant (GT vs. GG: OR=1.88, 95% CI=1.08-3.27, P=0.036) and overdominant (GT vs. GG+TT: OR=2.08, 95% CI=1.23-3.53, P=0.008) inheritance models. No significant relationship was identified between the rs1110839 G>T variant and disease risk/protection in childhood ALL. In conclusion, the findings of the present study indicated that rs4848320 and rs6726151 polymorphisms of PAX8-AS1 may be a risk factor for the development of childhood ALL. Further studies with larger sample sizes and different ethnicities are now required to confirm these findings.

Abstract
Essentials Data on surgery in factor XIII (FXIII) deficiency patients are scarce and lack standardized guidelines. Variable dosage of 10-50 U kg-1 was given to FXIII deficiency patients undergoing surgery. Surgical outcomes showed excellent hemostasis with a minimal risk of post-operative complications. Surgery can be performed safely in FXIII deficiency patients following FXIII administration. SUMMARY Background The lack of accepted standardized surgical guidelines leads to dependence on the treating physicians' and centers' experiences. Aim Our aim is to evaluate the surgical outcomes of a large group of congenital factor XIII deficiency (FXIIID) patients. Methods A case series study was conducted prior to surgery on congenital FXIIID patients in two major referral centers located in Iran from 2010 to 2016. All patients were on prophylaxis using plasma factor XIII concentrate (10 U kg-1 , every 28 days) except for three patients. Single doses of 10 U kg-1 or 30 U kg-1 plasma factor XIII concentrate were given before a minor procedure and circumcision, respectively. Two doses of plasma factor XIII concentrate, one 30 U kg-1 prior to the procedure and the second dose of 30 U kg-1 on postoperative day 3, were given for major surgery. The dose was 50 U kg-1 both before and after neurosurgical procedures. Results One hundred and sixty-two FXIIID patients underwent minor, major and obstetrical/gynecological surgeries. Median age of the patients was 14 years (ages ranged 15 days to 47 years). The male-to-female ratio was 89/73. Five postoperative complications, two bleeding and three thrombosis, were recorded. Conclusion Our study showed excellent hemostasis in FXIIID patients undergoing surgeries. During the period of these surgeries, we observed only 1.8% postoperative complications. Surgery can be performed safely in FXIIID patients, and our proposed treatment regimens lead to adequate hemostatic coverage with minimal risk, for both minor and major surgeries.

Abstract
: Diagnosis of factor XIII (FXIII) deficiency (FXIIID) as a rare bleeding disorder is a challenge worldwide. Thus, in the present study, we used different methods including two molecular methods for detection of FXIIID. This study was conducted on individuals suspected to FXIIID. All individuals were checked by two routinely used methods of clot solubility test in Iran and two other clot solubility tests as well as FXIII activity and antigen assays. Molecular analysis was performed by PCR-restriction fragment length polymorphism (PCR-RFLP) and tetra-primer amplification refractory mutation system (T-ARMS)-PCR for only FXIIID mutation in southeast Iran (p.Trp187Arg), previously associated with severe FXIIID. Out of 151 individuals, 26 had abnormal clot solubility test with all four methods. PCR-RFLP revealed that 27 patients were homozygotes for p.Trp187Arg, whereas 12 were heterozygotes. Molecular analysis revealed that in routinely used clot solubility combinations, two homozygotes (∼8%) were missed, whereas in two other combinations, one patient (∼4%) was missed. One false positive result was observed in routinely used methods, whereas further combinations don't have false positive. T-ARMS-PCR had three discrepancies with PCR-RFLP and sequencing confirmed that the results of T-ARMS-PCR were false. FXIII antigen assay diagnosed all homozygotes, whereas in FXIII activity assay, two homozygotes had higher than 5% FXIII activity that inconsistent with severe deficiency. It seems that clot solubility test is not enough sensitive and specific and molecular analysis is the most reliable method for detection of FXIIID in areas such Iran with one or few specific mutations.

Abstract
The association of celiac disease (CD) with cancers of gastrointestinal origin has been noted. However, coincidence of CD with nongastrointestinal neoplasms is an unusual event. Here we present five children with concurrent CD and nongastrointestinal neoplasms. All of the patients had positive serologic results for anti-tTG antibodies. Histological investigation of intestinal mucosa showed inflammation (Marsh score = 2) in all the patients. Two of these patients represented with germ cell malignancies. One patient had Wilms' tumor. To our knowledge, these are the first reports of coincidence of these two cancers with CD in children. From the remaining two patients, one was diagnosed with acute lymphoblastic leukemia, and the other with astrocytoma. The diagnosis of malignancy preceded CD diagnosis in all the patients (mean ages of cancer and CD diagnosis of 1.8 and 5.4 years old, respectively). Whether malignancy can promote immune deregulation and predispose to CD is uncertain. On the other hand, undiagnosed celiac may be a risk factor for cancer. Our results suggest a potential association of CD with malignancy nature of CD, however, occurrence of CD may be influenced by various intrinsic and extrinsic factors. There are few reports noting CD as a paraneoplastic condition. Further investigations are necessitated to stablish such relationship.

Abstract
Fragile histidine triad (FHIT) is a tumor suppressor gene, which is involved in several malignancies. Epigenetic alterations in FHIT have been hypothesized to contribute to tumorigenesis. The present study aimed to examine DNA promoter methylation and gene expression levels of FHIT in childhood acute lymphoblastic leukemia (ALL), in a sample of Iranian patients. The promoter methylation status of FHIT was analyzed in 100 patients diagnosed with ALL and 120 healthy control patients. mRNA expression levels were assessed in 30 new cases of ALL compared with 32 healthy controls. Hypermethylation of the FHIT promoter was significantly more frequent in patients with ALL than in healthy controls (OR=3.83, 95% CI=1.51-9.75, P=0.007). Furthermore, FHIT mRNA expression levels were significantly reduced in childhood ALL patients compared with healthy controls (P=0.032). The results of the present study revealed that dysregulation of the FHIT gene may contribute to the pathogenesis of childhood ALL. Future studies investigating a larger sample population with greater ethnic diversity would be beneficial, to confirm the results from the present study.

Abstract
Factor XIII deficiency (FXIIID) is a rare hereditary bleeding disorder arising from heterogeneous mutations, which can lead to life-threatening hemorrhage. The diagnosis of FXIIID is challenging due to normal standard coagulation assays requiring specific FXIII assays for diagnosis, which is especially difficult in developing countries. This report presents an overview of FXIIID diagnosis and laboratory methods and suggests an algorithm to improve diagnostic efficiency and prevent missed or delayed FXIIID diagnosis. Assays measuring FXIII activity: The currently available assays utilized to diagnose FXIIID, including an overview of their complexity, reliability, sensitivity, and specificity, as well as mutational analysis are reviewed. The use of a FXIII inhibitor assay is described. Diagnostic tools in FXIIID: Many laboratories are not equipped with quantitative FXIII activity assays, and if available, limitations in lower activity ranges are important to consider. Clot solubility tests are not standardized, have a low sensitivity, and are therefore not recommended as routine screening test; however, they are the first screening test in almost all coagulation laboratories in developing countries. To minimize the number of patients with undiagnosed FXIIID, test quality should be improved in less well-equipped laboratories. Common country-specific mutations may facilitate diagnosis through targeted genetic analysis in reference laboratories in suspected cases. However, genetic analysis may not be feasible in every country and may miss spontaneous mutations. Centralized FXIII activity measurements should also be considered. An algorithm for diagnosis of FXIIID including different approaches dependent upon laboratory capability is proposed.

Abstract
Background: Xmn-1 polymorphism of 𝜸Gglobin gene (HBG2) is a prominent quantitative trait loci (QTL) in β-thalassemia intermediate (β-TI). In current study, we evaluated the frequency of Xmn-1 polymorphism and its association with β-globin gene (HBB) alleles and Hb F level in β-TI patients in Sistan and Balouchestan province, south-east of Iran. Subjects and Methods: 45 β-TI patients were enrolled. HBB gene mutations and Xmn-1 polymorphism were determined by amplification-refractory mutation system (ARMS) PCR method. Hemoglobin profile was determined using capillary electrophoresis. Results: The study participants consisted of 26 (58%) males and 19 (42%) females. Mean age of the patients was 10.7±3.1 years old. Overall, Xmn-1 polymorphism was observed in 28 (62%) patients. Homozygous (TT) and heterozygous (CT) genotypes of the polymorphism represented with frequencies of 12 (26%) and 16 (35%), respectively. Main recognized HBB gene mutation was IVSI-5(G>C) with homozygous frequency of 44%. Non-zero (β+) alleles of HBB gene constituted 11.1 % (4 patients with heterozygous β+ and one with homozygous β+ genotype). Hb F level was significantly higher in patients with at least one Xmn-1allele (67.9±[Formula: see text]17.9%) than those without the polymorphism (19.5±20.3%, P<0.0001). Also, patients with homozygous genotype demonstrated significantly higher Hb F compared to heterozygous (CT) cases (respective percentages of 85±[Formula: see text]6.8 and 54.7±[Formula: see text]10.5, p<0.0001). Conclusion: Our results highlighted the role of Xmn-1 polymorphism as the main phenotypic modifier in β-TI patients in Sistan and Balouchestan province.

Abstract
Inheritance of mild mutations within the β-globin gene and coinheritance of α-thalassemia (α-thal) are known as two important genetic modifiers in β-thalassemia (β-thal) intermedia (β-TI). We aimed to evaluate the spectrum of β- and α-thal mutations in β-TI patients in Southeast Iran. Common β- and α-globin gene mutations were detected by amplification refractory mutation system-polymerase chain reaction (ARMS-PCR) and multiplex gap-PCR, respectively. There were 26 male (57.8%) and 19 female (42.2%) patients. HBB: c.92 + 5T > C [IVS-I-5 (G > C)] and HBB: c.-138C + 1G > A [IVS-II-I (G > A)] represented the prevalent alleles with respective frequencies of 60.0 and 10.0%. Other β-globin mutations included HBB: c.-138C > T [-88 (C > T)], HBB: c.27_28insG [frameshift codons (FSC) 8/9 (+G)], HBB: c.46delT [codon 15 (-T)], HBB: c.93-22_95del (IVS-I, 25 del), and the 619 bp deletion (NG_000007.3: g.71609_72227del619). The predominant genotypic combinations were β(0)/β(0) (68.9%), β(0)/β(+ )(8.9%) and β(+)/β(+ )(2.2%). Coinheritance of α-thal was observed in 33.0% of the patients, with the -α(3.7) (rightward) (NG_000006.1: g.34164_37967del3804) as the most common deletion (86.0%). One patient was diagnosed with the -α(4.2) (leftward) (AF221717) and one with the - -(MED) (g.24664_41064del16401) deletions, while no patients carried the -(α)(20.5) (g.15164_37864del22701), α(-5 nt) (HBA2: c.95 + 2_95_6delTGAGG) or codon 19 (-G) (HBA2: c.56delG) mutations. The alleviating molecular mechanism was not explainable by β(+ )or concurrent α-thal in more than half of our β-TI patients. This encourages conducting more studies to identify other contributing factors, especially Hb F-inducing genetic modifiers.

Abstract
We examined the possible relationship between three RAGE polymorphisms, -429C/T, -374 T/A, and 63-bp deletion, and susceptibility to childhood acute lymphoblastic leukemia (ALL) in an Iranian population. This study included 75 ALL patients and 115 healthy subjects. Genotyping was performed using HEXA-ARMS-polymerase chain reaction. We found no significant association among RAGE gene polymorphisms and the risk for ALL at genotype, allelic and haplotype levels (P > 0.05). The hemoglobin levels were higher in patients with RAGE -374 TT than in the TA carriers (P = 0.019). Our results demonstrated that the RAGE gene variations were not associated with risk of pediatrics ALL.

Abstract
Introduction: It has been well known that the microRNA biogenesis is involved in the pathogenesis of various diseases. We investigated the possible association between DROSHA rs642321 variant and risk of acute lymphocytic leukemia (ALL). Materials and Methods: We genotyped 75 children diagnosed with ALL and 115 age- and sex-matched children with no history of cancer of any type (as the control group) by the tetra amplification refractory mutation system-polymerase chain reaction. Results: We found that DROSHA rs642321 C > T variant significantly decreased the risk of ALL in codominant (TT vs. CC: odds ratio [OR] = 0.33, 95% confidence interval [CI] = 0.14–0.80, P = 0.020) and dominant (TT + CT vs. CC: OR = 0.51, 95% CI = 0.27–0.94, P = 0.037) inheritance model tested. The rs642321 T allele was associated with protective against ALL (OR = 0.58, 95% CI = 0.38–0.88, P = 0.011) in comparison with C allele. Conclusion: The study findings revealed that DROSHA rs642321 variant decreased the risk of pediatrics ALL in an Iranian population. Larger sample sizes with different ethnicities are needed to validate our findings.

Abstract
Aim: 3D printing can be applied for point-of-care personalized treatment. This study aimed to determine the manufacturability and characteristics of 3D printed, drug-loaded implants for alcohol misuse. Materials & methods: Disulfiram was the drug substance used and polylactic acid (PLA) the base material. Implantable devices were designed in silico. Drug and PLA were placed into the extruder to produce a 5% blend at 1.75-mm diameter. Material characterization included differential scanning calorimetry, thermogravimetric analysis plus inverse GC-surface energy analyzer. Results: Implantable constructs from the PLA feedstock were acquired. The extrusion processes had a detrimental effect on the active pharmaceutical ingredient-base blend. differential scanning calorimetry and thermogravimetric analysis analysis indicated drug–base interactions. Thermal history was found to influence inverse GC probe interaction. Conclusion: Drug-base incompatibilities must be considered during 3D printing.

Abstract
Long non-coding RNAs (lncRNAs) are a novel class of non-protein coding RNAs that are involved in a wide variety of biological processes. There are limited data regarding the impact of lnc-LAMC2-1:1 rs2147578 as well as CASC8 rs10505477 T>C polymorphisms on cancer development. Here we examined for the first time whether rs2147578 and rs10505477 polymorphisms are associated with childhood acute lymphoblastic leukemia (ALL) in a total of 110 cases and 120 healthy controls. Genotyping was achieved by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. The rs2147578 variant increased the risk of ALL in codominant (OR=4.33, 95%CI=2.00-9.37, p<0.0001, CG vs CC, and OR=5.81, 95%CI=2.30-14.69, p=0.0002, GG vs CC), dominant (OR=4.63, 95%CI=2.18-9.86, p<0.0001, CG+GG vs CC), overdominant (OR=1.74, 95%CI=1.02-2.97, p=0.0444, CG vs CC+GG) and allele (OR=1.91, 95%CI=1.32-2.77, p=0.0008, G vs C) inheritance models tested. No significant association was found between the CASC8 rs10505477 T>C variant and risk of childhood ALL. In conclusion, the present study revealed that the lnc-LAMC2-1:1 rs2147578 polymorphism may be a risk factor for developing childhood ALL. Further studies with larger sample sizes with different ethnicities are now required to confirm our findings.

Abstract
Background: Thalassemia is a chronic, inherited blood disorder, which in its most severe form, causes life-threatening anemia. Thalassemia patients not only engage with difficulties of blood transfusion and iron chelating therapy but also have some social challenges and health threatening factors. There are some reports on quality of life in thalassemia patients around the world from southeast of Asia to Italy in Europe and United States. In this study, we tried to evaluate and compare Health Related Quality of life (HRQoL) and the health utility in beta thalassemia major patients receiving different types of iron chelators and living in different socio-economical situations. Subjects and Methods: EQ-5D-3L accompanied by a Visual Analogue Scale (VAS) questionnaire was used. The respondents were patients with beta thalassemia major that were at least 12 years old selected from 3 provinces of Sistan-Blouchestan, Fars and Mazandaran. Comorbidities including heart complication, Diabetes Mellitus and Hepatitis and also types of iron chelators (oral, injection, combination of both) were also asked. Cross tab and ANOVA analysis conducted to evaluate each dimension score and health utility differences between provinces, iron chelation methods, comorbidities, age group and gender. Results: 528 patients answered the questionnaires. The health utility of patients that received oral iron chelator were 0.87 ± .01 for oral iron chelators versus 0.81 ± .01 for injection dosage form (p<0.05). Increase in age was accompanied by decrease in health utility. Females faced more usual activity problems, anxiety and depression. Heart problems were more prevalent in males. Conclusion: This study suggests that the quality of life of beta thalassemia major patients is dependent on type of iron chelation treatment which they received, the gender they have, the comorbidities they suffer and socio-economical situations they live in.

Abstract
BACKGROUND The present study was aimed to examine the possible association between methylene tetrahydrofolate reductase (MTHFR) gene polymorphisms and childhood acute lymphoblastic leukemia (ALL) in a sample of Iranian population. SUBJECTS AND METHODS A total of 220 subjects including 100 children diagnosed with ALL and 120 healthy children participated in the case-control study. The single nucleotide polymorphisms (SNPs) of MTHFR were determined by ARMS-PCR or PCR-RFLP method. RESULTS Our investigation revealed that rs13306561 both TC and TC + CC genotypes decreased the risk of ALL compared to TT genotype (OR=0.32, 95%CI=0.15-0.68, p=0.002 and OR=0.35, 95%CI=0.17-0.70, p=0.003, respectively). In addition, the rs13306561 C allele decreased the risk of ALL in comparison with T allele (OR=0.42, 95% CI=0.22-0.78, P=0.005). MTHFR rs1801131 (A1298C) polymorphism showed that the AC heterozygous genotype decreased the risk of ALL in comparison with AA homozygous genotype (OR=0.43, 95%CI=0.21-0.90, p=0.037). Neither the overall Chi-square comparison of cases and control subjects (𝜒2=5.54, p=0.063) nor the logistic regression analysis showed significant association between C677T polymorphism and ALL (OR=1.25, 95% CI=0.69-2.23, p=0.552; CT vs. CC). CONCLUSION The current investigation findings showed that MTHFR rs1801131 and rs13306561 polymorphisms decreased the risk of ALL in the population which has been studied. Further studies with larger sample sizes and different ethnicities are required to validate our findings.
