Abstract
Context Fetuin-A is a multifunctional protein and is known to be related to metabolic syndrome, vascular calcification, and inflammation. Objective The purpose of this study was to determine the effects of serum fetuin-A levels on autoimmune thyroiditis without thyroid dysfunction. Subjects and Methods This prospective case-control study was performed at the pediatric endocrinology outpatient clinic of a tertiary health institution in Istanbul, Turkey between July 2022 and October 2022. Serum fetuin-A levels were assessed using a human fetuin-A enzyme-linked immunosorbent assay (ELISA) kit (Elabscience Biotechnology, Houston, TX, USA). Results The study included 86 participants, of which 42 were patients with Hashimoto's thyroiditis (HT) and 44 were controls. Autoimmune thyroiditis without thyroid dysfunction was found to be related to lower plasma fetuin-A levels. There were no statistically significant differences in the neutrophil-to-lymphocyte ratio, fasting blood glucose level, insulin level, or HOMA-IR (Homeostatic Model Assessment for Insulin Resistance) value between the groups. A fetuin-A level of ≤162.22 µg/mL (80.95% sensitivity and 70.45% specificity) was found to support the identification of autoimmune thyroiditis. Conclusions The findings of our study suggest that autoimmune thyroiditis without thyroid dysfunction is related to lower fetuin-A levels. Low fetuin-A levels are known to be associated with an increased risk of cardiovascular disease, suggesting that careful monitoring is required in patients with low fetuin-A levels.

Abstract
BACKGROUND The aim of the study was to produce age and sex specific pediatric reference intervals (RIs) on a fully automated chemiluminescent immunoassay (CLIA) system. MATERIAL AND METHOD A total of 1586 patients' remnant sera were included in the study and free testosterone (FT), 17-OH progesterone (17OHP), androstenodione (A4) and insulin-like growth factor-1 (IGF-1) parameters were measured on MAGLUMI 2000 (Shenzhen New Industries Biomedical Engineering Co., Ltd. (Snibe), Shenzhen, China) CLIA analyser. After appropriate age and gender partitioning, specific intervals were calculated according to Clinical Laboratory Standart Institute's (CLSI) C28-A3 protocol. RESULTS All analytes showed sex and age dependent concentrations requiring several subgroups with specific reference intervals. 17OHP and A4 were found high with birth, declined thereafter: 17OHP by the end of 12 months and A4 by 6 months. So this period was also partitioned for these two hormones. All showed gradual increases by the end of 18 years. 17OHP, A4 and IGF-1 of girls were higher than boys around puberty as the result of earlier sexual development and maturation. FT values of boys and girls didn't differ from each other upto 10 years of age but boys had significantly higher values than girls afterwards. IGF-1 values gradually increase in both sexes upto the ages of 13, girls with significantly higher values than boys. In 13-18 years no significant gender difference was found. CONCLUSIONS We present method specific pediatric RIs, which are comparable with medical literature, necessary for interpretation of patient results.

Abstract
BACKGROUND The effectiveness of aspiration and vacuum filling method with an adaptor in reducing hemolysis was investigated. METHODS The study was conducted in the yellow zone of the Emergency department. Two different apparatuses that draw blood with two different techniques from an IV catheter were compared with our routine procedure. The first system drew blood with aspiration technique into 4.9 mL serum gel tube (Sarstedt S-Monovette®). The second was vacuum filling with a specific adaptor attached to the same catheter drawing the blood into vacuumed serum separator tubes (BD Vacutainer® SST™II and Luer-Lok™ Access Device (LLAD). In our routine, we use plastic syringes and deliver it into the same serum separator vacuum tubes. We measured the hemolysis index, AST, CK, potassium, and LDH. RESULTS Hemolysis rates of aspiration method vs. routine were 0.80% and 38.7% (p < 0.001) and of vacuum filling with adaptor vs. routine were 13.5% and 40.6%, respectively (p = 0.0001). The hemolysis rate of the aspiration method was lower than the vacuum filling adaptor method (p = 0.0004). Both techniques showed better performance when measured parameters were compared; aspiration technique being the superior (all p < 0.0001). CONCLUSIONS Aspiration method was more successful then vacuum filling methods in reducing hemolysis.

Abstract
BACKGROUND The study aimed to assess the analytical performance of the Access Sensitive Estradiol (SNSE2) Assay on a DxI800 (Beckman Coulter, Brea, CA, USA) and compared it with a Cobas E 601 (Roche Diagnostics, Penzberg, Germany). METHODS SNSE2 was assessed for imprecision, accuracy, limit of blank (LoB), limit of detection (LoD), limit of quantitation (LoQ), linearity, interference, and carryover. Two hundred and fourteen samples were run on both instruments. Bland-Altman plots, Passing-Bablok regression, and concordance correlation coefficient (CCC) graphs were used for comparisons. RESULTS Access SNSE2 showed appropriate assay performance characteristics in terms of imprecision, LoB, LoD, LoQ, linearity, and interference. The Bland-Altman analysis of DxI 800 yielded negative bias from Cobas E 601 and the deviations for E2 ≤ 150 pmol/L, 150 - 500 pmol/L, and ≥ 500 pmol/L were found as 0.8%, -15%, and -8.9%, respectively. DxI 800 and E170 systems showed poor agreement for E2 levels ≤ 150 pmol/L and 150 - 500 pmol/L with CCC values of 0.7404 and 0.8342. For E2 levels ≤ 150 pmol/L there was a significant amount of both proportional and constant error with the highest slope of 1.518 (1.269 to 1.761) and an intercept of -45.08 (-66.09 to 18.78, respectively, according to the Passing-Bablok regression analysis). CONCLUSIONS Analytical performance for SNSE2 assay was found appropriate. However, attempts to improve harmonization and standardization across assays do not seem to contribute much for E2 measurements. Results obtained with different systems cannot be used interchangeably and follow up of patients should be done with the same system.

Abstract
The aim of the study is to investigate factors that may cause radiation-induced lung disease (RILD) in patients undergoing stereotactic body radiotherapy (SBRT) for lung tumors. Medical records of patients treated between May 2018 and June 2019 with SBRT were retrospectively evaluated. All patients should have a diagnosis of either primary non-small cell lung cancer (NSCLC) or less than three metastases to lung from another primary. The median treatment dose was 50 Gy in 4-5 fractions. Tumor response and RILD were evaluated in thoracic computer tomography (CT) using RECIST criteria. 82 patients with 97 lung lesions were treated. The median age was 68 years (IQR = 62-76). With a median follow-up of 7.2 months (3-18 months), three patients had grade 3 radiation pneumonitis (RP). RILD was observed in 52% of cases. Patients who had RILD had a higher risk of symptomatic RP (p = 0.007). In multivariate analyses older age, previous lung radiotherapy history, and median planning treatment volume (PTV) D95 value of ≥ 48 Gy were associated with RILD. Local recurrence (LR) was observed in 5.1% of cases. There was no difference in overall survival and LR with the presence of RILD. Older age, previous lung radiotherapy history, and median PTV D95 value of ≥ 48 Gy seems to be associated with post-SBRT RILD.

Abstract
BACKGROUND The family planning program in Turkey was established in 1965 to curb the rapid increase in population growth. The last Demographic and Health Survey showed that about 64 % of married women in Turkey used contraception. OBJECTIVES This study examines of behaviour of family planning clients and provider in Eskisehir/Turkey, to see whether they can achieve this ideal parnership. METHODS Consultation between 83 physicians, 222 nurses and 324 clients requesting family planning methods were audiotaped and analysed for physicians and nurses communication style. Data were collected from 3 hospital and 14 small health units that give services in Eskisehir. The audiotaped consultations were coded using an adaptation of the RIAS which has been used extensively in both developed and developing countries and in statistical analysing chi(2) and t test were utilized. RESULTS AND CONCLUSION The single strongest factor was providers giving biomedical and technical information. The qualitative analysis of audiotapes found that most of clients' questions concern contraceptive side effects and symptoms. The next category social talk, consisted largely of greetings. Most of the providers (87.6 %) are women. The results show that providers dominate most counselling session and clients rarely take on active role.

Abstract
Nine newly isolated mushroom strains were tested to assess both their zinc tolerance and potential for zinc removal from an aqueous solution. Four strains of ectomycorrhizal fungi, namely Clavariadelphus truncatus (T 192), Rhizopogon roseolus (T 21), Lepista nuda (T 373), and Tricholoma equestre (T 174), along with five strains of white rot fungi, Lenzites betulina (S 2), Trametes hirsuta (T 587), Ganoderma spp. (T 99), Polyporus arcularius (T 438), and Ganoderma carnosum (M 88), were investigated using zinc-amended solid and liquid media. Their biosorption properties were also determined. The colony diameter and dry weight were used as tolerance indices for fungal growth. C. truncatus and T. equestre were not strongly inhibited at the highest concentrations of (225 mg/l) zinc in solid media. The most tolerant four strains with solid media, C. truncatus, G. carnosum, T. hirsuta, and T. equestre, were then chosen for tolerance tests in liquid media. An ectomycorrhizal strain, C. truncatus, was also detected as the most tolerant strain in liquid media. However, the metal-tolerant strains demonstrated weak activity in the biosorption studies. In contrast, the highest biosorption activity was presented by a more sensitive strain, G. carnosum. In addition, seven different biosorbent types from G. carnosum (M 88) were compared for their Zn (II) biosorption in batch experiments.

Abstract
OBJECTIVE To assess the clinical value of cervicovaginal fetal fibronectin (FFN) in the prediction of preterm delivery (PTD) in women with signs and symptoms of preterm labor (PTL). METHOD This investigation prospectively studied a cohort of a women with symptoms of PTL, between 24 and 37 weeks' gestation with < 3 cm of cervical dilatation and intact membranes. Cases were evaluated in terms of maternal demographic characteristics like age, body mass index, number of parities, previous PTL history, Bishop scores at admission, gestational age at delivery, mode of delivery, use of tocolytic or steroids, presence of histologic chorioamnionitis, neonatal outcomes and delivery before 34 weeks' gestation as well as within seven days of admission. RESULTS A total number of 68 cases were included in the study. There were no statistically significant differences between positive and negative FFN groups in terms of maternal characteristics, mode of delivery and adverse neonatal outcomes. However, FFN + cases had higher Bishop scores on admission (3.4 +/- 1.2 vs 2.5 +/- 0.3, p = 0.03) and lower gestational age at delivery (33.4 +/- 3.1 weeks vs 36.8 +/- 2.1 weeks, p = 0.002). Likelihood ratio (LR) for positive results was 1.83 (95% CI: 1.61-2.26) for predicting birth before 34 weeks' gestation, with a corresponding negative LR of 0.62 (95% CI: 0.3-1.2). LR for positive results was 4.34 (95% CI: 3.65-5.12) for predicting birth within seven days of testing, with a corresponding negative LR of 0.3 (95% CI: 0.2-0.5). CONCLUSION Based on the results of cervicovaginal FFN, positive tests represent an increased likelihood of PTD among women with symptoms of threatened preterm labor.

Abstract
This study was an attempt to determine whether the hormonal and clinical profiles of polycystic ovarian syndrome (PCOS) or non-PCOS cases whose only admission signs were oligo/anovulation or hirsutism. This retrospective study comprised a total number of 118, age-matched, young Turkish women with initial admission signs and symptoms of menstrual disorders (MD) like oligo/anovulation or hirsutism. Of these, 66 cases were diagnosed as PCOS, based on 2003 Rotterdam criteria [presence of two of first three criteria such as oligo- and/or anovulation, signs of clinical hyperandrogenism (HA-c) and/or biochemical signs of hyperandrogenism (HA-b) and polycystic ovaries on ultrasonography after exclusion of specific identifiable disorders]. Fifty-two women were diagnosed as cases of oligo/anovulation or hirsutism before the era of PCOS Rotterdam's consensus criteria. These two PCOS and non-PCOS cases were evaluated in terms of body mass index (BMI), waist-to-hip ratio, serum FSH, LH, estradiol (E2), dehydroepiandrosterone sulphate (DHEAS), androstendione (A) 17 hydroxyprogesterone (17-HP), fasting insulin, C-peptide levels, sex hormone-binding globulin (SHBG) and finally, ultrasonographic ovarian morphology. PCOS cases with unilateral and bilateral polycystic ovarian morphology on ultrasound scan were analyzed based on Rotterdam criteria. No statistically significant difference was detected among two groups, in terms of BMI, waist-to-hip ratio, serum FSH, LH, E2, fasting insulin, C-peptide levels (P > 0.05). However, blood levels of DHEAS, A and 17-HP were higher, whilst SHBG levels were remarkably lower (P = 0.008) in PCOS cases. Among PCOS group, hormonal and clinical characteristics did not differ, irrespective or uni- or bilaterality of ovarian morphology on ultrasonographic scan. Percentages of cases with androgenic alopecia, oily skin/acnea and increased ovarian volume were higher in PCOS group; whereas Ferriman-Gallwey score >/= 8 were similar between two groups. Total but not free testosterone remained high in PCOS group (P < 0.01). In both PCOS and non-PCOS cases, a linear correlation was apparent between BMI and insulin levels (r (s )= 0.69 and 0.32, P < 0.05, respectively). Among PCOS group, MD + HA-b + HA-c (n = 40) was present in 60.6% of subjects, MD + HA-b (n = 12) in 18.2%, and MD + HA-c (n = 14) in 21.2%. The three phenotypes did not differ in mean BMI, waist-to-hip ratio and biochemical characteristics. To conclude, non-PCOS women with only sign or symptom of oligo/anovulation or hirsutism had a more favorable endocrine milieu. These cases should be followed in vigilance in an aim to confront the development of short- and long-term adverse effects of impending PCOS in the future. Furthermore, different phenotypes of PCOS cases were clinically or biochemically similar in characteristics.

Abstract
A rare variation of the ulnar artery is presented on routine anatomical dissection in one male cadaver. The superficial ulnar artery was found to originate from the axillary artery. The free forearm flap is increasingly popular among plastic surgeons. As a result of this case, and a review of the literature to gain further knowledge of anatomical variations, it is advised that more attention should be paid clinically to this artery to prevent its injury.
