Background: Currently, glycans, which are known as functional molecules in the biological system, are being under study as potential cancer markers. This study aimed to determine the level of serum L-fucose and sialic acid as the biomarkers in patients with colorectal cancer (CRC). Materials and Methods: The patients with CRC (n=40, 20 men and 20 women) participated in the present study. The spectrophotometric method was used to measure the levels of L-fucose and sialic acid in the serum of the patients. SPSS (version 21) was used to analyze the obtained data. The results were expressed as mean ± SD. Results: The mean ± SD L-fucose level in patients with CRC was 27.46 ± 4.8 ng/mL, which was more than this level in the healthy control group (18.64±3.1 ng/mL). Also, the mean ± SD serum concentration of sialic acid in patients with CRC was 2.1 ± 0.41 ng/mL, which was more than the mean ± SD sialic acid level of 1.23±0.21 ng/mL in the healthy controls. Conclusion: Serum concentration of L-fucose and sialic acid increased significantly (P < 0.05) in patients with CRC compared with the healthy controls. We believe that determining serum L-fucose and sialic acid levels could be useful for the detection of CRC patients in the early stage.

Colorectal cancer (CRC) is one of the most common cancers worldwide usually diagnosed in the advanced stage. In this study, the serum concentration of tumor endothelial marker 1 (TEM1) was measured and correlated with clinicopathological features to evaluate whether TEM1 might serve as a biomarker for early CRC diagnosis, progression, and prognosis. The concentration of TEM1 was measured in the serum samples of 45 patients with CRC and 35 healthy individuals using enzyme-linked immunosorbent assay test. The mean serum concentration of TEM1 was significantly higher in the patients with CRC compared to the healthy individuals (1.31 ± 0.16 vs 0.92 ± 0.90 ng/mL; P < .001). The mean concentration of TEM1 significantly increased in the patients having CRC with early stage (stage I + II) compared to noncancer control individuals (stage I + II vs control 1.21 ± 0.13 ng/mL: 0.92 ± 0.90 ng/mL; P < .001). The TEM1 concentration in blood serum also showed a significant association with the development of T stages ( P < .001), N stages ( P < .001), and M stages ( P = .006). The TEM1 sensitivity and specificity in CRC detection are higher than routinely used blood markers (carcinoembryonic antigen [CEA] and carbohydrate antigen [Ca 19-9]). Patients with high TEM1 concentration (≥1.055 ng/mL) had a worse overall survival rate compared to the patients having CRC with low TEM1 concentration (<1.055 ng/mL). In conclusion, TEM1 can act as a potential diagnostic, progression, and prognostic serum biomarker for patients with CRC; TEM1 might be a good supplement for commonly used markers CEA and Ca 19-9.

Background: Colorectal cancer (CRC) has no significant clinical symptoms at the early stages, and the molecular differences in the serum of the patients and healthy subjects could be assessed to identify the biological markers that indicate the detection of this cancer at the levels of the biological system. Objectives: The present study aimed to assess the concentrations of the alpha-(1, 3)-fucosyltransferase IV (FUT4) enzyme and copper (Cu) and zinc (Zn) as biological elements. Methods: This case-control study was conducted on 40 patients with CRC, including 20 men and 20 women. A metal-free sterile tube was used to collect five milliliters of venous blood. The enzyme-linked immunosorbent assay (ELISA) based on the Biotin double-antibody sandwich technology was used to measure the human FUT4 in the sera. In addition, plasma zinc and copper values were determined using Zist Chem Diagnostics kits. Results: The mean FUT4 levels in the CRC patients was slightly higher than the control group (P = 0.17), and the mean serum copper and zinc levels of these patients were lower than the control group with a significance difference in this regard (P < 0.001). In addition, the AUC of FUT4, copper, and zinc was 0.58, 0.80, and 0.77, respectively. Conclusions: According to the results, the altered levels of FUT4, copper, and zinc in the serum of the CRC patients compared to the healthy controls could be an indicator associated with the CRC disease course. Furthermore, the unusual changes in the FUT4, copper, and zinc levels may signify CRC development, which plays a key role in the diagnosis and monitoring of this cancer.

Abstract Purpose: The aim of this study is to evaluate the tear osmolarity(TO) in patients with epiphora caused by primary acquired nasolacrimal-duct obstructions(PANDOs), before and one month after an external dacryocystorhinostomy(E-DCR) and trans-canalicular laser-assisted endoscopic dacryocystorhinostomy(TLA-DCR).Material-Methods: Twenty eyes of 21 patients(16 women, 5 men) who suffered from epiphora and, 20 healthy eyes of the same subjects were included in this study. External(Group 1) or laser-assisted(Group 2) DCR were applied to all patients with PANDO.Results: The mean age of the subjects was 60.09±8.46 in Group 1, 57.50±9.41 in Group 2 and, 55.13±9.38 in healthy control subjects. The mean period for complaints of epiphora was 1.9±0.7 years. Nasolacrimal duct irrigation was successful in all patients at the first-month visit after surgery. Group 1 had a mean TO of 284.16±12.43 mOsm/l and, Group 2 had 286.70±10.46 mOsm/l before DCR, and this increased to 295.75±5.86 mOsm/l and, 298.70±8.76 mOsm/l one month after DCR, respectively. Preoperative TO values in both groups were significant hypoosmolar compared with the control group (292.27±9.65 mOsm/l). No significant differences were detected between postoperative and control group TO values.Conclusion: We found no significant osmolarity changes between surgery and control groups.

Background. This study aimed to evaluate and compare changes in the mandibular trabecular bone pattern using the fractal dimension (FD) and lacunarity analysis in tobacco users with healthy controls. Methods. This study was carried out on digital panoramic radiographs of 225 subjects divided into three groups: smokeless tobacco users (SLTs), smokers, and control (n=75). ImageJ program with FracLac plugin was used to assess the FD and lacunarity of mandibular trabecular bone on the digital panoramic radiographs. Results. The differences in the mean FD values of the study and control groups were statistically significant (P<0.001). Mean FD was lower in the case groups than the control group, with SLTs having the least FD value. A significant difference in lacunarity was noted between SLTs and controls (P<0.001). On the contrary, there was no significant difference in lacunarity between smokers and controls. Conclusions. FD values were lower in tobacco users, suggesting that tobacco users have a less complex trabecular bone pattern than healthy controls. Higher lacunarity values in SLTs indicated a more heterogeneous bone pattern. These findings signify that FD and lacunarity analysis on digital panoramic radiographs can serve as promising predictive tools to assess bone quality for osteoporotic changes in tobacco users, thereby facilitating prompt referral for further management.

Introduction: Juvenile Idiopathic Arthritis (JIA) is a chronic rheumatic disease, with a prevalence of 1 in 1000 children under the age of 16 years. The clinical symptoms include inflammation of joints, swelling of synovial membrane resulting in growth disturbances and loss of bone density. Aim: To assess the effect of JIA on the development of Temporomandibular Joint (TMJ) and occlusion in children and young adolescents in the age group of 8-16 years and to evaluate the effect of TMJ arthritis on the growth of maxilla and mandible. Materials and Methods: This is a descriptive cross-sectional study with a study and control group. A total of 44 children with JIA attending the Department of Rheumatology, Nizam Institute of Medical Sciences (NIMS), within the age group of 8-16 years were screened and enrolled in study from May-July 2014. A gender and sex-matched healthy control group were enrolled from Paediatric Dentistry outpatient specialty. For the measurement and comparison of arch perimeters of mandible and maxilla, the JIA and control group were divided into sub-groups 1 (8-10 y), 2 (11-13 y), and 3 (14-16 y). All the parameters were recorded and subjected to statistical analysis. An Independent sample t-test was used to find a significant difference for maxillary and mandibular arch perimeters among both the groups. Chi-square test was used to know the difference for TMJ parameters, occlusion and occlusal abnormalities. The level of significance was set at p<0.05 for all tests. Results: Children in the JIA group had reported TMJ pain on movement (40.9%), clicking sounds (36.4%), and dislocation (22.7%). Angle’s class II malocclusion was seen in 36.4% compared to the control group (4.5%). The mean arch perimeter of the mandible was significantly less among JIA children in subgroups 2 (73.00±3.03 mm), and 3 (71.77±6.27 mm) when compared to healthy controls. Other occlusal abnormalities such as increased overjet (34.1%), decreased overbite (31.8%), and crowding (54.5%) were reported in significant percentages compared to healthy controls. Conclusion: The mean arch perimeter of the mandible in the JIA group is less when compared to children of the same age in the control group. There is increased predilection of developing Angle’s class II Malocclusion in the JIA group. From a paediatric dentist perspective, it’s important to understand the overall impact of JIA on stomatognathic system, and an early intervention is recommended.

Objectives. Nocturnal enuresis is a common pediatric problem, the etiology of which is unclear. In the present study, vitamin B12 and folate levels were measured in children with nocturnal enuresis and compared with those in healthy control group children to investigate whether there was any relation with enuresis and neurogenic maturation as a first time in the literature. Methods. In this cross-sectional study, we included thirty children (16 girls, 14 boys) who had presented with primary nocturnal enuresis (PNE) complaints in the study group and 31 children (13 girls, 18 boys) in the control group. Body weight and height measurements were obtained and complete blood counts and vitamin B12 and folate levels were measured in all children. Results. No difference was found in age, height, and weight between study and control groups. Also the mean levels of the hemoglobin, hematocrit, and mean corpuscular volume (MCV) were not different between the two groups. Significantly lower mean vitamin B12 and folate levels were found in the enuresis group compared with the control group. Conclusions. Further studies are needed to clarify B12 and folate deficiency in larger series so that these tests can be included in routine investigations of enuretic children.

ObjectiveThe product of the G72 gene is an activator of d-amino acid oxidase and has been suggested to play a role in the pathogenesis of schizophrenia. Increased G72 protein levels may be associated with disturbed glutamatergic transmission and increased reactive oxygen species. Only one pilot study by Lin et al. has investigated the potential role of serum G72 protein levels as a biomarker for schizophrenia. In this study, we aimed to compare serum G72 protein levels between patients with schizophrenia and healthy controls, and to retest the results of the previous pilot study.Materials and methodsIn total, 107 patients with a diagnosis of schizophrenia according to the inclusion and exclusion criteria and 60 age–sex-matched healthy controls were included in the study. The groups were compared regarding serum G72 protein levels.ResultsThe mean serum G72 protein values were 495.90±152.03 pg/ml in the schizophrenia group and 346.10±102.08 pg/ml in the healthy control group. The mean serum G72 protein level was significantly increased in the schizophrenia group compared with the healthy control group (t=−3.89, p<0.001). A receiver operating characteristics analysis was performed to compare the schizophrenia and healthy control groups. It was determined that the cut-off value was 141.51 pg/ml with a sensitivity of 0.991 and a specificity of 0.821.ConclusionWe suggest that serum G72 protein levels may represent a candidate biomarker for schizophrenia and have confirmed the results of the previous preliminary study. Additional studies with larger sample sizes and the inclusion of first episode schizophrenia patients are required to clarify the reliability and validity of serum G72 protein levels as a biomarker for schizophrenia.

Background. The aim of this study was to investigate the mean platelet volume (MPV) of patients with retinal vein occlusion (RVO).Methods. Hundred and ninty-three patients with the diagnosis of RVO and 83 healthy control subjects were included in this retrospective study. Retinal vein occlusion was diagnosed based on clinical examination. All patients and control subjects underwent complete ocular examination. MPV, hematocrit, hemoglobin, and platelet count of the participants were recorded. The data of patients with RVO was compared with the control subjects.Results. Patients with RVO had significantly higher MPV values ( fL) compared with the control subjects ( fL) (). No significant difference was found in platelet counts between RVO group and the control group ( 109/L and  109/L, resp., ), Mean platelet volume was an independent predictor of RVO (odds ratio (OR) = 1.43; 95% confidence interval (CI) = 1.09–1.89; ).Conclusion. Our results demonstrated that the MPV values were significantly higher in patients with RVO, suggesting that larger platelets may contribute to the pathogenesis of the RVOs.

Despite advances in the characterization of colorectal cancer (CRC), it still faces a poor prognosis. There is growing evidence that gut microbiota and their metabolites potentially contribute to the development of CRC. Thus, microbial dysbiosis and their metabolites associated with CRC, based on stool samples, may be used to advantage to provide an excellent opportunity to find possible biomarkers for the screening, early detection, prevention, and treatment of CRC. Using 16S rRNA amplicon sequencing coupled with statistical analysis, this study analyzed the cause–effect shift of the microbial taxa and their metabolites that was associated with the fecal gut microbiota of 17 healthy controls, 21 polyps patients, and 21 cancer patients. The microbial taxonomic shift analysis revealed striking differences among the healthy control, polyps and cancer groups. At the phylum level, Synergistetes was reduced significantly in the polyps group compared to the healthy control and cancer group. Additionally, at the genus level and in association with the cancer group, a total of 12 genera were highly enriched in abundance. In contrast, only Oscillosprira was significantly higher in abundance in the healthy control group. Comparisons of the polyps and cancer groups showed a total of 18 significantly enriched genera. Among them, 78% of the genera associated with the cancer group were in higher abundance, whereas the remaining genera showed a higher abundance in the polyps group. Additionally, the comparison of healthy control and polyp groups showed six significantly abundant genera. More than 66% of these genera showed a reduced abundance in the polyps group than in healthy controls, whereas the remaining genera were highly abundant in the polyps group. Based on tumor presence and absence, the abundance of Olsenella and Lactobacillus at the genus level was significantly reduced in the patient group compared to healthy controls. The significant microbial function prediction revealed an increase in the abundance of metabolites in the polyps and cancer groups compared to healthy controls. A correlation analysis revealed a higher contribution of Dorea in the predicted functions. This study showed dysbiosis of gut microbiota at the taxonomic level and their metabolic functions among healthy subjects and in two stages of colorectal cancer, including adenoma and adenocarcinoma, which might serve as potential biomarkers for the early diagnosis and treatment of CRC.

Abstract.The relationship between Hashimoto’s thyroiditis and vitamin D has been demonstrated in several studies. The aim of the present study was to evaluate vitamin D concentrations in patients with Hashimoto’s thyroiditis, the effect of vitamin D therapy on the course of disease, and to determine changes in thyroid autoantibody status and cardiovascular risk after vitamin D therapy. We included 75 patients with Hashimoto’s thyroiditis and 43 healthy individuals. Vitamin D deficiency is defined as a 25-hydroxy vitamin D (25(OH)D3) concentration less than 20ng/mL. Vitamin D deficient patients were given 50.000 units of 25(OH)D3 weekly for eight weeks in accordance with the Endocrine Society guidelines. All evaluations were repeated after 2 months of treatment. Patients with Hashimoto’s thyroiditis had significantly lower vitamin D concentrations compared with the controls (9.37±0.69 ng/mL vs 11.95±1.01 ng/mL, p < 0.05, respectively). Thyroid autoantibodies were significantly decreased by vitamin D replacement treatment in patients with euthyroid Hashimoto’s thyroiditis. Also, HDL cholesterol concentrations improved in the euthyroid Hashimoto group after treatment. The mean free thyroxine (fT4) concentrations were 0.89±0.02 ng/dL in patients with Hashimoto’s thyroiditis and 1.07±0.03 ng/dL in the healthy control group (p < 0.001). The mean thyroid volumes were 7.71±0.44 mL in patients with Hashimoto’s thyroiditis and 5.46±0.63 mL in the healthy control group (p < 0.01). Vitamin D deficiency is frequent in Hashimoto’s thyroiditis and treatment of patients with this condition with Vitamin D may slow down the course of development of hypothyroidism and also decrease cardiovascular risks in these patients. Vitamin D measurement and replacement may be critical in these patients.
