[PMID: 38041916 DOI: 10.1016/j.radi.2023.11.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2023] [Revised: 11/16/2023] [Accepted: 11/22/2023] [Indexed: 12/04/2023]
Abstract
INTRODUCTION The utilization of radiation shielding material positioned between the both breasts are crucial for the reduction of glandular dose and the safeguarding of the contralateral breast during mammographic procedures. This study proposes an alternative substance for shielding the contralateral breast from radiation exposure during mammography screening. METHODS In this study, we present an analysis of the shielding effectiveness of transparent glass that has been doped with Tantalum (V) oxide encoded as BTZT6. The evaluation of this shielding material was conducted using the MCNPX code, specifically for the ipsilateral and contralateral breasts. The design of the left and right breast phantoms involved the creation of three-layer heterogeneous breast phantoms, consisting of varying proportions of glandular tissue (25%, 50%, and 75%). The design of BTZT6 and lead-acrylic shielding screens is implemented using the MCNPX code. The comparative analysis of dose outcomes is conducted to assess the protective efficacy of BTZT6 and lead-acrylic shielding screens. RESULTS The utilization of BTZT6 shielding material resulted in a reduction in both breast dose and skin dose exposure when compared to the lead-acrylic shield. CONCLUSION Based on the findings acquired, the utilization of BTZT6 shielding material screens during mammography procedures involving X-rays with energy levels ranging from 26 to 30 keV is associated with a decrease in radiation dose. IMPLICATIONS FOR PRACTICE It can be inferred that the utilization of BTZT6 demonstrates potential efficacy in mitigating excessive radiation exposure to the breasts and facilitating the quantification of glandular doses in mammography procedures.

Tungsten (VI) oxide reinforced antimony glasses for radiation safety applications: A throughout investigation for determination of radiation shielding properties and transmission factors. Heliyon 2023; 9:e17838. [PMID: 37456003 PMCID: PMC10345364 DOI: 10.1016/j.heliyon.2023.e17838] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Revised: 06/28/2023] [Accepted: 06/28/2023] [Indexed: 07/18/2023] Open
Abstract
We report the functional assessment of tungsten (VI) oxide on gamma-ray attenuation properties of 60Sb2O3-(40-x)NaPO3-xWO3 antimony glasses. The elemental mass-fractions and glass-densities of each glass sample are specified separately for the MCNPX Monte Carlo code. In addition to fundamental gamma absorption properties, Transmission Factors throughout a broad radioisotope energy range were measured. According to findings, holmium (Ho) incorporation into the glass structure resulted in a net increase of 0.3406 g/cm3, whereas cerium (Ce) addition resulted in a net increase of 0.2047 g/cm3. The 40% WO3 reinforced S7 sample was found to have the greatest LAC value, even though seven glass samples exhibited identical behavior. The S2 sample had the lowest HVL values among the glass groups evaluated in this work, computed in the energy range of 0.015-15 MeV. The lowest EBF and EABF values were reported for 40% WO3 reinforced S7 sample with the highest LAC and density values. According to the findings of this research, WO3 will likely make a significant contribution to the gamma ray absorption properties of antimony glasses, which are employed for optical and structural modification. Therefore, it can be concluded that WO3 may be treated monotonically and can be employed successfully in circumstances where gamma-ray absorption characteristics, optical properties, and structural qualities need to be enhanced.

Abstract
Background and Aim There are criteria that include many organ systems to predict the prognosis in acute pancreatitis (AP) patients. In this study, we aimed to show how the course of the disease changes according to the Balthazar classification in AP patients presenting with renal failure. Methods and Materials Our study included 352 patients who were admitted to the Emergency Service of our hospital and were diagnosed and hospitalized with AP. According to the Balthazar score, patients with scores of 0-2, 4-6, and 8-10 were evaluated as mild, moderate, and severe AP, respectively. Demographic data (age, gender) of all patients were documented. The etiology of AP was determined in all patients. Biliary, drug/toxic, alcohol, infections, hyperlipidemia, post-endoscopic retrograde cholangiopancreatography (ERCP), genetics, hypercalcemia, structural anomalies, and malignancy were evaluated as the etiology. Those without any underlying pathology were evaluated as idiopathic AP. The patients were divided into two groups as those with and without renal insufficiency. All patients underwent helical computed tomography (section 64, Aquilion; Toshiba Medical Systems, Tokyo) within the first 12 hours and between days 3 and 7. Pancreas, peripancreatic and extrapancreatic findings, and complications were examined. "The Statistical Package for the Social Sciences 19.0 (SPSS Armonk, NY: IBM Corp.)" was used for all analyses. Kolmogorov-Smirnov test and histograms were used to determine whether there was a normal distribution. The non-parametric data of the groups were compared using the Mann-Whitney U test and the parametric data using the ındependent t test. Chi-square test was used to test categorical data. Cases with P < 0.05 were considered statistically significant. Results : While 22 (6.2%) patients had renal insufficiency, 332 (95.8%) patients did not have renal insufficiency. In the evaluation made in terms of AP severity; according to Balthazar classification at admission, there was no difference in mild and moderate pancreatitis for kidney insufficiency in both groups, but it was significantly higher in the group with severe pancreatitis [2 (9.1%) versus 1 (0.3%), P < 0.001]. In the evaluation made after 72 hours; renal failure was significantly lower in the group with mild pancreatitis [11 (50.0%) versus 245 (73.8%), P: 0.016] and severe renal failure was significantly higher in severe pancreatitis [7 (31.8%) versus 13 (%) 3.9), P < 0.001]. Conclusions Early intensive care unit admission and close follow-up and early treatment in AP patients change the course of the disease. In our study, we showed that serum creatinine level is an important parameter in the course of AP and has a predictive value for the course of the disease.

Toward the strengthening of radioprotection during mammography examinations through transparent glass screens: A benchmarking between experimental and Monte Carlo simulation studies. Front Public Health 2023; 11:1171209. [PMID: 37064659 PMCID: PMC10102610 DOI: 10.3389/fpubh.2023.1171209] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Accepted: 03/07/2023] [Indexed: 04/03/2023] Open
Abstract
IntroductionA lead-acrylic protective screen is suggested to reduce radiation exposure to the unexposed breast during mammography. The presence of toxic lead in its structure may harm the tissues with which it comes in contact. This study aimed to design a CdO-rich quaternary tellurite glass screen (C40) and evaluate its efficiency compared to the Lead-Acrylic protective screen.MethodsA three-layer advanced heterogeneous breast phantom designed in MCNPX (version 2.7.0) general-purpose Monte Carlo code. Lead acrylic and C40 shielding screens were modeled in the MCNPX and installed between the right and left breast. The reliability of the absorption differences between the lead acrylic and C40 glass were assessed.Results and discussionThe results showed that C40 protective glass screen has much superior protection properties compared to the lead acrylic protective screen. The amount of total dose absorbed in the unexposed breast for C40 was found to be much less than that for lead-based acrylic. The protection provided by the C40 glass screen is 35–38% superior to that of the Lead-Acrylic screen. The C40 offer the opportunity to avoid the toxic Pb in the structure of Lead-Acrylic material and may be utilized for mammography to offer superior radioprotection to Lead-Acrylic and significantly lower the dose amount in the unexposed breast. It can be concluded that transparent glass screens may be utilized for radiation protection purposes in critical diagnostic radiology applications through mammography.

Comparative analysis on application conditions of indium (III) oxide-reinforced glasses in nuclear waste management and source transportation: A Monte Carlo simulation study. Heliyon 2023; 9:e14274. [PMID: 36950638 PMCID: PMC10025019 DOI: 10.1016/j.heliyon.2023.e14274] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Revised: 02/27/2023] [Accepted: 03/01/2023] [Indexed: 03/09/2023] Open
Abstract
This study's primary objective is to provide the preliminary findings of novel research on the design of Indium (III) oxide-reinforced glass container that were thoroughly developed for the purpose of a nuclear material container for transportation and waste management applications. The shielding characteristics of an Indium (III) oxide-reinforced glass container with a certain elemental composition against the 60Co radioisotope was thoroughly evaluated. The energy deposition in the air surrounding the designed portable glass containers is measured using MCNPX general-purpose Monte Carlo code. Simulation studies were carried out using Lenovo-P620 workstation and the number of tracks was defined as 108 in each simulation phase. According to results, the indium oxide-doped C6 (TZI8) container exhibits superior protective properties compared to other conventional container materials such as 0.5Bitumen-0.5 Cement, Pb Glass composite, Steel-Magnetite concrete. In addition to its superiority in terms of nuclear safety, it is proposed that the source's simultaneous observation and monitoring, as well as the C6 (TZI8) glass structure's transparency, be underlined as significant advantages. High-density glasses, which may replace undesirable materials such as concrete and lead, provide several advantages in terms of production ease, non-toxic properties, and resource monitoring. In conclusion, the use of Indium (III) oxide-reinforced glass with its high transparency and outstanding protection properties may be a substantial choice in places where concrete is required to ensure the safety of nuclear materials.

Utilization of three-layers heterogeneous mammographic phantom through MCNPX code for breast and chest radiation dose levels at different diagnostic X-ray energies: A Monte Carlo simulation study. Front Public Health 2023; 11:1136864. [PMID: 36935709 PMCID: PMC10022908 DOI: 10.3389/fpubh.2023.1136864] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Accepted: 02/14/2023] [Indexed: 03/06/2023] Open
Abstract
Introduction We report the breast and chest radiation dose assessment for mammographic examinations using a three-layer heterogeneous breast phantom through the MCNPX Monte Carlo code. Methods A three-layer heterogeneous phantom along with compression plates and X-ray source are modeled. The validation of the simulation code is obtained using the data of AAPM TG-195 report. Deposited energy amount as a function of increasing source energy is calculated over a wide energy range. The behavioral changes in X-ray absorption as well as transmission are examined using the F6 Tally Mesh extension of MCNPX code. Moreover, deposited energy amount is calculated for modeled body phantom in the same energy range. Results and discussions The diverse distribution of glands has a significant impact on the quantity of energy received by the various breast layers. In layers with a low glandular ratio, low-energy primary X-ray penetrability is highest. In response to an increase in energy, the absorption in layers with a low glandular ratio decreased. This results in the X-rays releasing their energy in the bottom layers. Additionally, the increase in energy increases the quantity of energy absorbed by the tissues around the breast.

Degenerative changes of lumbar spine and their clinical implications in patients with axial spondyloarthritis. Clin Rheumatol 2023; 42:111-116. [PMID: 35922576 DOI: 10.1007/s10067-022-06321-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2022] [Revised: 07/16/2022] [Accepted: 07/27/2022] [Indexed: 01/11/2023]
Abstract
The objective of this study was to assess degenerative changes (DCs) on magnetic resonance imaging (MRI) of lumbar spine in axial spondyloarthritis (axSpA) and non-specific mechanical low back pain (mLBP). Patients were consecutively recruited and all underwent MRI of the lumbar spine in this cross-sectional study. Disk degeneration (DD, Pfirrmann classification), endplate changes (Modic, types 1, 2, and 3), annular fissure, disk bulging, and protrusion or extrusion at each lumbar spinal level were assessed using anonymized images. Patients with axSpA were assessed for disease activity, functioning, and quality of life. Univariate and subsequent multivariate logistic regression analyses with adjustments of various covariates were used to assess association between MRI findings and clinical variables. One hundred twenty-three patients had non-radiographic (nr-axSpA) and 144 had radiographic axSpA/ankylosing spondylitis (AS). Degenerative changes were more prevalent in patients with mLBP (n = 105) than axSpA. Disk degeneration was the most prevalent MRI finding, followed by annular fissure, disk herniation (protrusion or extrusion), and Modic changes (MCs) in axSpA. Disk herniation was more prevalent in patients with nr-axSpA compared to AS. Modic changes (OR = 6.455), lumbar disk herniation (OR = 2.278), annular fissure (OR = 2.842), conventional synthetic or biologic disease-modifying antirheumatic drugs (csDMARDs) non-users (OR = 2.225), and advanced age (OR = 31.556) were factors associated with an increased risk of DD in axSpA. Coexisting DD increased the burden of disease in axSpA. A considerable proportion of patients with axSpA had DD at the lumbar spine. These degenerative changes might explain some of the complaints and should not been overlooked in patients with axSpA. Key Points • Lumbar herniated nucleus pulposus (LHNP) is more frequent in nr-axSpA while MC is more frequent in AS. • DD may cause an increase in BASFI and BASMI scores in axSpA. • Spinal DCs might be an alternative explanation for low back complaints and should not been overlooked in patients with axSpA.

Abstract
In this study, it was aimed to develop a novel disinfectant from various essential oils containing active components with antimicrobial activity. The mixture of oregano, cinnamon and clove oils (1 : 1 : 1) with 10% oil concentration (SOM) was used as potential disinfectant on various areas and showed the highest antimicrobial activity among oil combinations tested. SOM reduced the numbers of total mesophilic aerobic bacteria (TMAB; 2·27 log CFU per 25 cm2 ) and Escherichia coli (4·60 log CFU per 25 cm2 ) under the detection limits. Application of SOM (1, 2, 3, 4 and 6%) into incubators reduced TMAB and mould-yeast counts of incubator air by 82·9 and 100% respectively. SOM application (3%) into ambient air also reduced its TMAB and mould-yeast counts by 92 and 84·6% respectively. While ethanol is commonly used for the disinfection of environments, equipment and surfaces, SOM is an important alternative that may also be used for the disinfection of various surfaces as well as air.

Abstract
Trazodone (TRZ) is an antidepressant drug commonly used in the treatment of depression, anxiety, and insomnia. Although some studies demonstrated the adverse effects of TRZ related to cardiovascular system, the conflicting results were observed in these studies. Therefore, we aimed to investigate the cardiac adverse effects of TRZ in rats at repeated doses in our study. In accordance with this purpose, TRZ was administered orally to rats at 5, 10, and 20 mg/kg doses for 28 days. Electrocardiogram records, serum aspartate aminotransferase (AST), lactate dehydrogenase, creatine kinase-myoglobin band, cardiac troponin-T (cTn-T) levels, DNA damage in cardiomyocytes, and histologic view of heart tissues were evaluated. In addition, glutathione (GSH) and malondialdehyde (MDA) levels were measured to determine the oxidative status of cardiac tissue after TRZ administration. Heart rate was decreased, PR interval was prolonged, and QRS and T amplitudes were decreased in 20 mg/kg TRZ-administered group compared to the control group. Serum AST and cTn-T levels were significantly increased in 10 and 20 mg/kg TRZ-administered rats with respect to control rats. DNA damage was significantly increased in these groups. Additionally, degenerative histopathologic findings were observed in TRZ-administered groups. Although there was no difference in MDA levels between groups, GSH levels were significantly decreased in 10 and 20 mg/kg TRZ-administered groups compared to the control group. Our results have shown that TRZ induced cardiotoxicity in rats dose-dependently. It is assumed that oxidative stress related to GSH depletion may be accompanied by these adverse effects.

Abstract
OBJECTIVE Although the prevalence of peripheral and extra-articular disease in ankylosing spondylitis (AS) has been assessed in many studies, data on non-radiographic axial spondyloarthritis (nr-axSpA) is scanty. The aim of this study was first, to compare radiographic-axSpA/AS (r-axSpA/AS) and nr-axSpA concerning peripheral arthritis and extra-articular manifestations (EAMs), and second, to assess potential differences between patient subgroups with or without EAMs regarding disease burden. METHODS Data was extracted from our single center axSpA database. Patients having at least one of the EAMs (uveitis and/or inflammatory bowel disease (IBD) and/or psoriasis) were compared to those who did not have EAMs. Patients' clinical data including disease activity, functional and psychological status, physical limitations, quality of life (QoL) and magnetic resonance imaging of sacroiliac joints (SIJ MR) were evaluated. RESULTS Patients with nr-axSpA (n=193) were younger, had female predominance, better functional and physical status, higher frequency of bone edema in SIJ MR and peripheral arthritis but similar QoL, prevalence of HLA B27 and EAMs compared to r-axSpA/AS (n=352). The prevalence of current or ever uveitis (14.5 vs 15.3%, p=0.791), psoriasis (6.2 vs 5.4%, p=0.689) or IBD (4.1 vs 3.4%, p=0.663) in nr-axSpA and r-axSpA/AS were similar. In both subgroup of patients, EAMs positive and negative patients had similar functional status and QoL, as well as disease activity and laboratory parameters. CONCLUSION Patients with nr-axSpA and r-axSpA/AS have similar prevalence of EAMs and clinical burden of disease. Having EAMs does not have a major influence on clinical parameters and patient reported outcome measures in nr-axSpA and r-axSpA/AS.

Abstract
Migraine is a primary headache disorder which involves both genetic and environmental components. Since angiotensin-converting enzyme (ACE) and matrix metalloproteinase (MMP) share the same homology, we investigated whether the MMP-3 and ACE I/D gene variants are involved in migraine risk and whether the ACE variant might act in combination with the MMP-3 genetic variant in patients with migraine. This is the first study to evaluate the association between MMP-3 and ACE polymorphisms, and migraine. Genotypes were determined by polymerase chain reaction. The frequencies of 5A5A genotypes of the MMP-3 and D allele of ACE were significantly elevated, but II genotypes of the ACE and 6A allele of MMP-3 significantly decreased in all patients. The combined DD/5A5A and ID/5A5A genotypes increased the risk of migraine. Individuals who were homozygous for the deletion (D) allele showed increased ACE activity. Subjects with the 5A5A genotype and/or D allele or with the combined DD/5A5A or ID/5A5A might be more susceptible to migraine development. In contrast, subjects with the II and/or 6A6A genotypes may be protected from migraine development. The greater activity of the 5A5A and DD genotypes might result in vascular reactivity that is more pronounced in migraine. Taken together, our data suggest that numerous genes may influence ACE activity. Discovery of new genes might better clarify the pathogenesis of migraine and open an avenue to therapeutic strategies against migraine.

Abstract
AIM To assess the validity of Assessment in Spondyloarthritis International Society (ASAS) endorsed Ankylosing Spondylitis Disease Activity Score (ASDAS) C-reactive protein (-CRP) and ASDAS erythrocyte sedimentation rate (-ESR) in axial spondyloarthritis (axSpA) and to estimate the cut-off values for male and female patients with axSpA. METHODS Patients with axSpA were assessed for disease activity, functions, mobility and AS Quality of Life (ASQoL) and pain. The discriminant ability of ASDAS versions was assessed using standardized mean differences. Optimal cut-off values of ASDAS versions were calculated. RESULTS Patients with axSpA were included (196 AS, 164 non-radiographic axSpA). ASDAS versions and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) had good correlations with patient's global (PtG) and physician's global (PhG) assessment in both groups; however, men had relatively higher coefficients. Women had significantly higher pain, ASQoL, ASDAS-ESR, BASDAI item scores, PtG, PhG and ESR. Discriminant abilities of ASDAS-CRP, ASDAS-ESR and BASDAI were similar in men and women regarding low and high disease activity. ASDAS cut-offs are quite similar in both genders and in accordance with predefined values. The cut-offs for ASDAS-ESR were relatively lower than ASDAS-CRP and women tend to have higher cut-offs than men. CONCLUSION The construct validity of ASDAS-CRP to discriminate low and high disease activity and cut-off values are similar in male and female patients with axSpA; however, cut-offs for ASDAS-ESR need to be defined.

Abstract
AIM To compare the effects of laparoscopic versus conventional inguinal hernia repair techniques on patients physical activity. MATERIALS AND METHODS Ninety-three patients (between 20 and 59 years old) who presented with a need for inguinal hernia repair at the private Safa Hospital, General Surgery Clinic, were evaluated prospectively between November 2011 and March 2013. The patients mean age was 46.1 (+-12.9) years. They were divided into three groups according to hernia repair technique. Thirty underwent total extraperitoneal repair (TEP), 31 had transabdominalpreperitoneal repair (TAPP) and 32 had modified Bassiniprolene mesh grafting (MBPMG). All patients were examined in the physical therapy and rehabilitation unit just before and after the operation. Lower extremity muscles isokinetic and isometric functions were measured with the Cybex isokinetic testing device. Patients length of stay in hospital, need for analgesics in the postoperative period, visual analogue scale (VAS) scores, time of return to work and postoperative complications were also compared. RESULTS Patients need for postoperative analgesics, the use of VAS scoring system (between 0 and 10), complication rates and the patients VAS scores on movement results were similar to those in the literature. On the postoperative third day, measurements recorded by the Cybex isokinetic testing device showed that the loss of strength in the lower extremities after the MBPMG procedure was greater than with TAPP and TEP. The isokinetic and isometric assessment of all cases revealed that postoperative mean muscle strength loss was two-thirds less in association with the laparoscopic procedure. Within a 95% confidence interval (CI), the significance of findings was accepted at P-values of less than 0.05 (p 0.05). CONCLUSION The quantitative data showed that there is a more favourable impact from laparoscopic hernia repair versus open surgery on patients physical activity and return to active work.

Abstract
AIM Psoriatic arthritis (PsA) is a chronic, inflammatory disease. The purpose of this study was to examine the association between PsA and comorbid conditions. This is the first study to investigate comorbid diseases in PsA in Turkey. METHODS This study was performed under the auspices of the Anatolian Group for the Assessment in Rheumatic Diseases (ANGARD) and involved participation by six university research hospitals. Patients diagnosed with and treated for PsA on the basis of clinical, radiological and laboratory findings and expert opinion were monitored using standardized examination methods and jointly prepared forms. Clinical status, accompanying systemic diseases and surgical history were recorded. RESULTS One hundred and seventy-three patients with PsA (75 male, 98 female, mean age 41.8) and 138 patients with rheumatoid arthritis (RA) (17 male, 121 female, mean age 48.6) and 67 with psoriasis (PsO) (43 male, 24 female, mean age 36.1) were included in the study. No accompanying disease was determined in 72.8% of PsA, 50.0% of RA and 80.6% of PsO groups. In regression analysis, patients with PsA had higher risk for cataract/glaucoma surgery (odds ratio [OR] = 11.99; 95% CI 1.36-105.4, P = 0.025) compared to patients with RA, and higher risk for hypertension (HT) (OR = 4.26; 95% CI 1.27-14.23, P = 0.018) compared to the patients with PsO. CONCLUSION Patients with PsA have relatively lower frequency of comorbidities like diabetes mellitus, HT and cataract/glaucoma surgery compared to the patients with RA. The increased risk for having cataract/glaucoma surgery in RA compared to PsA may be particularly attributed to the more prevalent glucocorticoid use in RA.

Abstract
Rheumatoid arthritis (RA) is a common chronic inflammatory disease and periarticular osteoporosis or osteopenia of the inflamed hand joints is an early feature of RA. Quantitative measurement of hand bone loss may be an outcome measure for the detection of joint destruction and disease progression in early RA. This systematic review examines the published literature reporting hand bone mass in patients with RA, particularly those using the dual X-ray absorptiometry (DXA) methods. The majority of the studies reported that hand bone loss is associated with disease activity, functional status and radiological progression in early RA. Quantitative measurement of hand bone mineral density by DXA may be a useful and practical outcome measure in RA and may be predictive for radiographic progression or functional status in patients with early RA.

Abstract
This article aims to compare the risks of depression and anxiety in patients with ankylosing spondylitis (AS) and nonradiographic axial spondyloarthritis (nr-axSpA) and investigate the relationship among self-reported outcome measures, clinical parameters, and physical variables of patients with axSpA. Patients with axSpA were recruited from Erciyes Spondyloarthritis Cohort. The patients met Assessment of Spondyloarthritis International Society classification criteria for axial SpA and were assessed in a cross-sectional study design for visual analog scale (VAS) pain, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), Ankylosing Spondylitis Quality of Life questionnaire (ASQoL), and Ankylosing Spondylitis Disease Activity Score-C-reactive protein (ASDAS-CRP). Psychological status was evaluated using the hospital anxiety and depression scale (HADS). Multivariate logistic regression analysis was applied to determine the associations between psychological variables and clinical parameters after adjusting for confounding variables. Of the 316 patients (142 nr-axSpA, 174 AS), 139 (44%) had high risk for depression (HADS-D score ≥ 7) and 71 (22.5%) for anxiety (HADS-A score ≥ 10). HADS-D and HADS-A scores were similar between patients with AS and nr-axSpA. Patients with high risk for depression and anxiety had higher scores in BASDAI, BASFI, and ASDAS-CRP, and also poorer scores in VAS pain and ASQoL. Multivariate logistic regression analysis showed that the ASDAS-CRP, ASQoL, BASDAI, as well as educational level were factors associated with the risk of depression whereas the ASQoL and educational level were factors associated with the risk of anxiety. Patients with nr-axSpA and AS have similar burden of psychological distress. The quality of life (ASQoL) and educational level were factors associated with the risk of both depression and anxiety whereas disease activity (BASDAI and ASDAS-CRP) was the independent risk factor associated with depression but not anxiety in axSpA. These findings suggest that psychological status should be examined while assessing patients with axSpA including AS and nr-axSpA.

Discriminant validity of the Ankylosing Spondylitis Disease Activity Score (ASDAS) in patients with non-radiographic axial spondyloarthritis and ankylosing spondylitis: a cohort study. Rheumatol Int 2014; 35:981-9.

Abstract
The aim of this study was to assess discriminant validity of Ankylosing Spondylitis Disease Activity Score (ASDAS)-C-reactive protein (-CRP) and ASDAS-erythrocyte sedimentation rate (-ESR) and to compare with The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) as clinical tools for the measurement of disease activity in patients with non-radiographic axial spondyloarthritis (nr-axSpA) and ankylosing spondylitis (AS). Also, the cut-off values for ASDAS-CRP in nr-axSpA and AS is revisited. Patients with axSpA were recruited from Erciyes Spondyloarthritis Cohort (ESPAC) and were assessed for disease activity, quality of life and functional measures. The discriminatory ability of ASDAS-CRP and ASDAS-ESR was assessed using standardized mean differences and receiver operating characteristic (ROC) curves analysis. Optimal cut-off values for disease activity scores were calculated. Two hundred and eighty-seven patients with axSpA (nr-axSpA:132, AS:155) were included in this study. Two ASDAS versions and BASDAI had good correlations with patient's and physician's global assessment in both groups. Discriminatory ability of ASDAS-CRP, ASDAS-ESR and BASDAI were similar in patients with nr-axSpA and AS when the patients were assigned into low and high disease activity according to the ASAS partial remission, patient's and physician's global assessment scores (based on the comparison of ROC curves). ASDAS cut-off values are quite similar between groups indicating that ASDAS-CRP works similarly well in nr-axSpA and AS. The performance of ASDAS to discriminate low and high disease activity and cut-off values are quite similar in patients with AS and non-radiographic axial SpA.

Abstract
The female steroid, 17β-estradiol (E2), is important for pancreatic β-cell function and acts via at least three estrogen receptors (ER), ERα, ERβ, and the G-protein coupled ER (GPER). Using a pancreas-specific ERα knockout mouse generated using the Cre-lox-P system and a Pdx1-Cre transgenic line (PERαKO−/−), we previously reported that islet ERα suppresses islet glucolipotoxicity and prevents β-cell dysfunction induced by high fat feeding. We also showed that E2 acts via ERα to prevent β-cell apoptosis in vivo. However, the contribution of the islet ERα to β-cell survival in vivo, without the contribution of ERα in other tissues is still unclear. Using the PERαKO−/− mouse, we show that ERα mRNA expression is only decreased by 20% in the arcuate nucleus of the hypothalamus, without a parallel decrease in the VMH, making it a reliable model of pancreas-specific ERα elimination. Following exposure to alloxan-induced oxidative stress in vivo, female and male PERαKO−/− mice exhibited a predisposition to β-cell destruction and insulin deficient diabetes. In male PERαKO−/− mice, exposure to E2 partially prevented alloxan-induced β-cell destruction and diabetes. ERα mRNA expression was induced by hyperglycemia in vivo in islets from young mice as well as in cultured rat islets. The induction of ERα mRNA by hyperglycemia was retained in insulin receptor-deficient β-cells, demonstrating independence from direct insulin regulation. These findings suggest that induction of ERα expression acts to naturally protect β-cells against oxidative injury.

Abstract
AIM To assess bone mass in women with systemic sclerosis (SSc) in comparison to age and sex-matched patients with rheumatoid arthritis (RA), and to evaluate factors influencing bone mineral density (BMD). METHODS Patients were consecutively recruited and assessed for BMD at the lumbar spine and hip by dual-energy X-ray absorptiometry (DEXA) using a densitometer. In SSc, the extent of skin involvement, modified Rodnan skin thickness score (mRSS) and Medsger disease severity index were assessed. RESULTS Forty-three patients with SSc and 38 age-matched patients with RA were included. There was no difference in BMD measurements between patients with diffuse or limited SSc. Patients with SSc had similar risk factors associated with osteoporosis (OP) or low bone mass except for low body mass index (BMI) and low vitamin D levels compared to patients with RA. Lumbar spinal BMD and T score were similar between groups. Total hip and femoral neck BMD and T score at femoral neck and total hip were significantly lower in patient with SSc versus RA. There was significant association between mRSS, Medsger severity score (peripheral vascular involvement and skin) and femoral BMD. CONCLUSION There is an increased risk for bone loss in patients with SSc and the risk of OP is associated with disease severity, prolonged menopause and disease duration. The complex pathophysiology of bone metabolism as well as complex pathogenesis of the SSc pose some difficulty reaching clear-cut conclusions on the causal relationship between SSc and bone loss.

Abstract
AIMS/HYPOTHESIS Pancreatic islet transplantation (PIT) offers a physiological treatment for type 1 diabetes, but the failure of islet engraftment hinders its application. The female hormone 17β-oestradiol (E2) favours islet survival and stimulates angiogenesis, raising the possibility that E2 may enhance islet engraftment following PIT. METHODS To explore this hypothesis, we used an insulin-deficient model with xenotransplantation of a marginal dose of human islets in nude mice rendered diabetic with streptozotocin. This was followed by 4 weeks of treatment with vehicle, E2, the non-feminising oestrogen 17α-oestradiol (17α-E2), the oestrogen receptor (ER) α agonist propyl-pyrazole-triol (PPT), the ERβ agonist diarylpropionitrile (DPN) or the G protein-coupled oestrogen receptor (GPER) agonist G1. RESULTS Treatment with E2, 17α-E2, PPT, DPN or G1 acutely improved blood glucose and eventually promoted islet engraftment, thus reversing diabetes. The effects of E2 were retained in the presence of immunosuppression and persisted after discontinuation of E2 treatment. E2 produced an acute decrease in graft hypoxic damage and suppressed beta cell apoptosis. E2 also acutely suppressed hyperglucagonaemia without altering insulin secretion, leading to normalisation of blood glucose. CONCLUSIONS/INTERPRETATION During PIT, E2 synergistic actions contribute to enhancing human islet-graft survival, revascularisation and functional mass. This study identifies E2 as a short-term treatment to improve PIT.

Abstract
PURPOSE To compare physician and nurse practitioner accuracy in recognizing cervical dysplasia during colposcopy. MATERIALS AND METHODS A retrospective review was performed of cervical excisional biopsies from 2007 to 2009 performed by gynecologists and nurse practitioners in the same patient population. Cervical cone biopsy and loop electrosurgical excision procedure (LEEP) pathology were used as a gold standard compared to the previous colposcopy biopsies. RESULTS Four hundred fifty-five patients qualified for the study. Patients were stratified according to age: under 30 years, 30-39, and 40 and above. For physicians, 77% of high-grade colposcopy biopsy results agreed with high-grade pathology on cone biopsy or LEEP. This was statistically similar to nurse practitioner results (p = 0.12). Likewise, there was no significant difference between physician and nurse practitioner accuracy within the various patient age strata. CONCLUSION Colposcopy biopsy results compared to cone biopsy or LEEP results were statistically similar between gynecologists and nurse practitioners.

Abstract
AIM To evaluate whether mucolytic agents have an adjuvant role with antibiotics in the treatment of children with rhinosinusitis. METHODS Ninety-two children with rhinosinusitis were recruited for this randomized, placebo controlled, double-blinded clinical trial. Mean age was 8.5 +/- 3.2 years. Erdosteine (5-8 mg/kg/day) was administered to 49 children, and 43 children received placebo. Changes in symptoms were recorded with the standard S5 scoring for 14 days. Complete resolution of symptoms on day 14 was considered to be clinical improvement. RESULTS Eighty-one participants completed the study. Forty-one were in the treatment group and 40 in the placebo group. The average S5 scoring value at the onset of study was 11.0 in treatment group and 12.1 in placebo group. On day 14, mean scores were 3.1 in the treatment group and 2.8 in the placebo group. Complete improvement was 78% in the treatment group and 74.4% in the placebo group. There was no significant difference between the groups. There were no clinically detected serious side effects or complications in both groups. CONCLUSION Use of erdosteine as a mucolytic agent in children with acute rhinosinusitis does not directly affect the success of treatment.

Abstract
We examined whether the GRIK3 (T928G) polymorphic variants in patients with schizophrenia are different from those of their first-degree relatives and healthy controls. The study population was composed of 256 patients with schizophrenia, 305 first-degree relatives of schizophrenia patients and 242 healthy control subjects. The GRIK3 (T928G) polymorphism was determined by restriction fragment length polymorphism. The frequency of the TT genotype was predominant, whereas the GG genotype was rare among all groups. The frequencies of GRIK3 (T928G) genotype distributions in the patients with schizophrenia were similar to those of their relatives. The frequency of the GG genotype was significantly higher in patients than in healthy controls. Similarly, GG genotype distribution in relatives was elevated compared with that in controls, but this value did not reach statistical significance. On the other hand, the subgroups of schizophrenia patients did not show a significant association with the GRIK3 (T928G) gene. It appears that the patients share the same (GRIK3) T928G gene variants with their relatives. One interpretation of our findings is that the relatives are at risk for the development of schizophrenia in the future.

Abstract
Aim:Chronic idiopathic urticaria (CIU) is a frequently occurring disease that seems to be associated with a number of psychological factors. This study aims to determine the frequency of psychiatric disorders and to assess the depression and anxiety symptom severity in a group of children with chronic idiopathic urticaria (CIU).Method:The study group included 30 children, ranging in age from 8 to 16 years, with CIU who attended to the Pediatric Allergy Clinic of the Istanbul Faculty of Medicine and 30 healthy subjects matched for age and sex. The psychiatric disorders were evaluated by using Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version (K-SADS-PL). State-Trait Anxiety Inventory (STAI), Children’s Depression Inventory (CDI) and Child Behavior Checklist (4-18) were used to examine the levels of depression and anxiety.Results:The K-SADS-PL revealed a psychiatric diagnosis in 63% of the patients. In terms of the distribution of psychiatric diagnoses, the most frequently occurring diagnosis was anxiety disorders (33%), namely simple phobia (21%) and social anxiety disorder (18%). State anxiety scores were significantly higher in children with CIU than controls but not trait anxiety and depression scores. No significant relationships were found between urticaria activity score, duration of illness, age onset and depression and anxiety scores.Conclusion:Psychiatric disorders were frequent in the group children with CIU. Clinicians should be more aware of accompanying psychiatric symptoms in this group of cases.

Abstract
We investigated the effect of polymorphic variants of c.1298A>C (Glu429Ala) and c.677C>T (Ala222Val) in methylenetetrahydrofolate (MTHFR) gene on the total homocysteine (tHcy), folate and B12 levels in patients with bipolar disorder, first-degree relatives of patients, and controls. The c.677C>T and c.1298A>C polymorphisms in MTHFR were determined by polymerase chain reaction-restriction fragment length polymorphism in 197 bipolar patients, 278 relatives and 238 controls. tHcy and folate and vitamin B12 levels were measured by Fluorescence Polarization Immunoassay and Electrochemiluminescence, respectively. The tHcy was significantly increased in patients and relatives. In contrast, folate and B12 were significantly lower in patients and relatives. Gender was not considered as a significant determinant in the multivariate analysis. Genotypes of c.1298A>C and c.677C>T were correlated with tHcy, folate and B12. Patients and relatives carrying TT and/or AA and AC genotypes had elevated tHcy and reduced folate and B12 levels. High tHcy but low folate and vitamin B12 levels may be a risk factor for development of bipolar disorder.
