Abstract
AIM We sought to evaluate the information, attitude, and behaviors toward organ donation among health workers in the eastern Black Sea region of Turkey. METHOD This descriptive study was performed between December 2008 and November 2009. It involved 1,545 health personnel in 8 state hospitals in the eastern Black Sea region of Turkey, excluding the university hospitals in the towns of Trabzon, Rize, Gümüşhane, and Giresun. Educational seminars regarding organ transplantation and donation were arranged for the hospitals in the study. Questionnaires on the subject distributed to the participants were collected before the seminars began. They contained questions about occupation, gender, age, previous organ donation, whether the person would consider donating if they had not already volunteered (if not, the reasons why), whether any relatives had volunteered to donate organs, whether anyone close to them had volunteered to donate organs, whether they would donate organs in the event of a relative's death, and what they might think if they were to require an organ transplant. Following the seminars, participants were given the opportunity to obtain organ donation cards from a stand on site. Data were analyzed using the chi-square test. RESULTS Eighty-one participants (5.2%), including 46 women (5.2%) and 35 men (5.3%), had previously officially volunteered to donate organs (P = .875). One hundred thirty-seven health personnel were willing to donate organs by visiting the donation stand after the seminars. The main reasons for participants who had not volunteered to donate organs failing to do so were lack of information about donation and procedures (28.4%), lack of interest in the subject (23.2%), and Islamic religious beliefs and/or traditions (19.6%). One hundred eighty health personnel (11.7%) had family members or relatives who had volunteered to donate organs. Asked whether they would donate that person's organs in the event of the death of a relative, 93 doctors (67.6%), 225 nonphysician health personnel (41.1%), and 345 other participants (43.1%) stated that they would not (P < .0005). CONCLUSIONS Health workers play a key role to overcome the difficulties encountered regarding organ donation. This study showed the need for constant effective education seminars to enhance knowledge and sensitivity on the part of health workers.

Abstract
This study used finite element analysis to evaluate the retentive tips of bar clasps made from different alloys and using different designs in order to determine whether or not different materials and tip forms are suitable for bar clasp applications. Co-Cr, Ti and Type IV Au alloys were selected based on their physical and mechanical properties. The 3D finite element models of three different bar clasp retentive tip geometries prepared from Co-Cr, Ti and Type IV Au alloys were constructed using the finite element software package MSC.Marc. Analysis of a concentrated load of 5 N applied to the removable partial denture approach arms in an occlusal direction was performed. Although stress distribution and localisation within bar clasps with different retentive tips were observed to be similar and were concentrated in the approach arm, stress intensities differed in all models.

Abstract
OBJECTIVE The aim of this study was to evaluate the effect of radioactive iodine (RAI) ablation therapy on the complete blood count (CBC) in thyroid cancer patients. METHODS One hundred sixty four patients undergoing RAI ablation therapy after total thyroidectomy were included. CBC results were available from the patients' medical records at the time of ablation and at the 1st, 6th, and 12th months after RAI therapy. RESULTS Hemoglobin (Hb), white blood cell (WBC) and platelet (Plt) values were significantly lower than baseline at 1 month after treatment (p <0.0001). Hb and WBC values were increased at the 6th month and at the 1st year. Plt values increased at the 6th month but had decreased again at the 1st year. The values were usually in normal ranges except in the patients with low pretreatment Hb and WBC values. CONCLUSION RAI ablation therapy in thyroid cancer patients is a safe treatment modality without any serious or persistent hematological side effects.

Abstract
LIM domain only-2 (LMO2) is an important regulator of hematopoietic stem cell development. LMO2 is also expressed in blast cells of different types of acute leukemia. Here, we analyzed the LMO2 protein expression in acute myeloid leukemia (AML) and B-cell acute lymphoblastic leukemia (B-ALL) and examined whether the LMO2 protein expression can predict outcomes of patients with acute leukemia. Patients with acute B-ALL (22 cases) and AML (57 cases) were examined using immunohistochemistry for LMO2 on paraffin-embedded bone marrow biopsies. We report that LMO2 protein is expressed in a significant proportion of B-ALL and AML and the staining of LMO2 protein does not predict survival in acute leukemia.

Abstract
PURPOSE recently, molecular subclassification of breast carcinomas has been proposed as a new prognostic parameter. METHODS we classified 222 invasive breast carcinoma cases in 5 molecular subtypes by using tissue microarray (TMA) and immunohistochemistry methods. These subtypes were luminal A (estrogen receptor/ER and/or progesterone receptor/ PR positive), luminal B (ER and/or PR positive + HER2 positive), HER2-expressing type (ER and PR negative, HER2 positive), basal-like type (ER, PR and HER2 negative, positive with at least one of these myoepithelial markers: CK5/6, CK14, EGFR) and null type (ER, PR, HER2 and myoepithelial markers negative). We compared these subtypes according to their clinicopathological features and GATA3 expression. RESULTS luminal A was the most frequent subtype. According to overall survival rates, HER2-expressing and basal- like types had the worst prognosis, while luminal A had the best. However, luminal B had the worst prognosis according to disease free survival. Most of the squamous differentiated metaplastic carcinomas were basal-like type. Tubular and mucinous carcinomas were luminal A. Most basal-like tumors were grade III. The majority of grade I tumors were luminal A. GATA3 positivity was associated with low grade tumors and luminal A subtype. CONCLUSION molecular classification can be accepted as an independent prognostic factor for invasive breast carcinomas. GATA3 expression was associated with luminal A and low histological grade. However, it wasn't shown as an independent parameter.

Abstract
This study was conducted to investigate the effectiveness of serum levels of free beta-hCG, progesterone, CA125 and their combined use in the prediction of first trimester abortions. A total of 140 singleton pregnant women between 5 and 13 weeks' gestational age were included as Group I (n = 21) who resulted in abortion including missed abortion, incomplete abortion, complete abortion and inevitable abortion; Group II (n = 129) included normal pregnancies. When using the free beta-hCG level of <20 ng/ml as a cut off point, the sensitivity, specificity, PPV and NPV were 91%, 82%, 46% and 98%, when using a progesterone of <15 ng/ml as a cut off point, they were 91%, 89%, 59%, 98%. The single measurement of free beta-hCG or progesterone levels can be useful in the prediction of first trimester spontaneous abortions, but using progesterone may be recommended since it has high availability and low cost.

Abstract
BACKGROUND Breast cancer is the most common malignancy in women. Axillary lymph node involvement and tumor size are the most significant prognostic factors in breast cancer. However, more factors are needed for evaluating the prognosis and individualizing the treatment in these patients. Intracellular adhesion molecule E-cadherin, antiapopitotic protein bcl-2, and p53 might have predictive and prognostic properties in breast cancer. OBJECTIVE We have investigated the effects of E-cadherin, bcl-2, and p53 on disease free survival and overall survival in patients with breast cancer. METHODS Positivity of aforementioned genes was detected with immunohistochemistry staining. Seventy-six women patients with invasive ductal and lobular breast cancer who had received adjuvant therapy were included in the study. RESULTS Bcl-2, E-cadherin, and p53 expression in tumor tissue specimens were found in 26.31%, 35.52%, and 9.21%, respectively. Mean duration of follow-up was 93.58 +/- 3.40 months. In multivariate analyses, axillary lymph node presence and C-erb-B2 overexpression were a strong negative prognostic factor of disease free survival and overall survival. E-cadherin and bcl-2 failed to have an effect on disease free survival and overall survival in our study. In addition, p53 overexpression was determined in a limited number of patients. CONCLUSIONS The results of this study showed that E-cadherin, bcl-2, and p53 did not have any significant prognostic value for our patients. In order to arrive at a decision, we need studies, which include more patients and long follow-up periods (Tab. 2, Fig. 2, Ref. 24).

Abstract
AIMS We studied determinants of serum apolipoprotein C-III (apoC-III) and whether levels of apoC-III or its fractions predict metabolic syndrome (MetS), Type 2 diabetes and coronary heart disease (CHD). METHODS The predictive value of apoC-III, measured by immunoturbimetric immunoassay in 802 tracked individuals of a Turkish general population in determining cardiometabolic risk was assessed over 4.4 +/- 1.2 years' follow-up. Patients with MetS, Type 2 diabetes and CHD at baseline were excluded. RESULTS Total apoC-III, as well as both fractions, was significantly, linearly and inversely related to smoking status, positively to alcohol usage and to levels of complement C3. Mid and high tertiles of total or non-high density lipoprotein (HDL) apoC-III predicted significantly and independently incident MetS; they predicted CHD with risk ratios of 1.6 [95% confidence intervals (CI) 1.02-2.5], for 1 sd increment, after adjustments that included HDL cholesterol and body mass index (BMI). The highest tertile of HDL apoC-III was a major independent predictor of new-onset diabetes with a 2.5-fold risk ratio for 1 sd increment (95% CI 1.5-4.0) in combined sexes, after adjustment for waist circumference, HDL cholesterol and other confounders and was a better predictor than waist girth. CONCLUSIONS Serum total apoC-III or its fractions are linearly and inversely associated with smoking, positively with alcohol usage and serum complement C3. The presumably dysfunctional HDL apoC-III is a stronger predictor of Type 2 diabetes than waist girth in Turks. Non-HDL apoC-III predicts strongly the development of MetS as well as incident CHD, independent of HDL cholesterol, BMI and non-lipid factors. The atherogenicity of apoC-III and dysfunctionality of HDL apoC-III carry huge public health implications in Turks.

Abstract
OBJECTIVES The aim of this study was to determine the prevalence of primary Sjogren's syndrome (pSS) in a general Turkish population according to the latest proposed American-European Consensus Group (AECG) criteria and European-1 (EU-1) criteria. METHODS The study was conducted in two districts of Izmir and involved 2835 subjects 20 years of age and older. In the first stage, face-to-face interviews were performed at the registered households. In the second stage, subjects reporting symptoms of both dry eye and dry mouth were invited to the hospital for a full examination, which included Schirmer-1, sialometry and serologic tests. In the third stage, a minor salivary gland biopsy was performed as required. RESULTS A total of 2887 subjects were contacted and a complete interview was obtained for 2835 (1551 female, 1284 male) subjects. A total of 159 subjects (126 female, 33 male) confirmed oral and ocular dryness, and 86 of these patients (54.1%) underwent a detailed clinical examination in the hospital. pSS was diagnosed in 10 patients (nine females) according to the EU-1 criteria, and in six patients (six females) according to the AECG criteria. We found a minimum crude prevalence of 0.21% [95% confidence interval (CI): 0.03-0.29] in the sample population and an age-sex adjusted prevalence of 0.16% (95% CI: 0.06-0.35), according to AECG criteria. According to EU-1 criteria, these prevalence rates were found to be 0.35% (95% CI: 0.10-0.45) and 0.28% (95% CI: 0.13-0.51) respectively. CONCLUSION The pSS prevalence rates found in the Turkish population in this study were lower than the estimated prevalence rate in a general population.

Abstract
PURPOSE The objectives of this study were to determine the levels of lifetime cigarette use, daily use, and current use among young people (aged 15-19 years) and to examine the risk factors contributing to regular smoking. METHODS The number of students was determined proportionately to the numbers of students in all the high schools in the province of Trabzon in Turkey. The data were gathered using the questionnaire method. A total of 4666 students participated in the study. The chi-square test and logistic regression analysis were used in data analysis. RESULTS Of the 4666 students who took part in the study, the level of lifetime cigarette use was 38.2% (n = 1796), that of lifetime daily cigarette use was 10.5% (n = 491), and that of current cigarette use was 9.5% (n = 447). Male students (P < .0005), those whose mothers were smokers (P < .0005), those whose fathers smoked (P = .005), those whose siblings smoked (P<.0005), those whose friends smoked (P < .0005), those whose teachers smoked (P = .001), and low achievers in school (P < .0005) stated that they significantly smoked on a more regular basis. According to the results of the logistic regression analysis, the following risk factors were statistically significant: male students smoked 3.02 times (95% CI 2.20-4.16) more than females, those whose mothers were smokers smoked 1.57 times (95% CI 1.09-2.28) more than those whose mothers were not, those whose friends were smokers smoked 2.42 times (95% CI 1.73-3.39) more than those whose friends were non-smokers, poor achievers in school smoked 2.62 times (95% CI 1.97-3.49) more than high achievers, and those without poor grades smoked 1.75 times more (95% CI 1.23-2.40), the risk rising 1.06 times (95% CI 1.01-1.11) with earlier age at first experimentation. The risk of daily cigarette use was observed to decline by 0.91 times (95% CI 0.84-0.98) with increasing numbers of siblings. CONCLUSION Effective smoking prevention programs should take into account the dominant influence of peer groups in the onset and continuation of smoking.

Abstract
BACKGROUND Lifestyle and metabolic determinants of incident hypertension in a population with a high prevalence of metabolic syndrome (MetS) need to be further assessed. METHODS A representative sample of middle-aged and elderly Turkish adults was prospectively evaluated over a mean 7.4 years, after exclusion of prevalent hypertension and major renal dysfunction. RESULTS In 2,427 men and women, aged 45.8 +/- 11.7 years, Kaplan-Meier analysis showed in combined genders mean time to incident hypertension to be 7.23 years in never, 7.78 years in current smokers (P < 0.001). Age and female sex were major determinants of subsequent hypertension after adjustment for physical activity grade, family income bracket, smoking status, usage of alcohol and of hormone replacement or birth control pill. Relative risk (RR) for incident hypertension of current vs. never smoking was reduced in women (P = 0.058) and both genders combined (P = 0.054). Former smokers uniformly exhibited significantly higher risk for the development of hypertension than both never (P = 0.054) and current (P < 0.001) smokers, whereby abdominally obese individuals were at increased risk. In further multivariable models, circulating C-reactive protein (CRP) and fasting insulin emerged as modest independent determinants and waist girth, modulated by current smoking, as a major determinant of subsequent hypertension. CONCLUSIONS Age, female sex, and waist circumference are major and serum insulin and CRP modest determinants of incident hypertension in middle-aged Turkish adults in whom current cigarette smoking plays a protective role at borderline significance, largely by modulating waist girth. Former smokers with abdominal obesity are under higher risk of subsequent hypertension than current smokers.

Abstract
BACKGROUND Predictive value of apolipoprotein (apo) A-I for incident hypertension, metabolic syndrome (MetS), type 2 diabetes (DM) and coronary heart disease (CHD) needs further exploration. METHODS A representative sample of Turkish adults was studied with this purpose prospectively. Sex-specific apoA-I tertiles were examined regarding cardiometabolic risk. RESULTS AND CONCLUSIONS A total of 1044 men and 1067 women (aged 49+/-12 years at baseline) were followed up over 7.4 years. High serum apoA-I levels were significantly associated in multivariable analysis with female sex, aging, alcohol intake, (inversely) cigarette smoking and, in women, with systolic blood pressure. Risk of diabetes was predicted in logistic regression in both genders by top versus bottom apoA-I tertile (RR 1.98; [95%CI 1.31; 3.0]), additive to age, body mass index (BMI), C-reactive protein (CRP), HDL-cholesterol and lipid lowering drugs. By adding sex hormone-binding globulin to the model in a subset of the sample, the association between high apoA-I and incident diabetes was attenuated only in women. ApoA-I tertiles tended to be positively associated also with hypertension and CHD only in women but this did not reach significance. High compared with low serum apoA-I levels nearly double the risk for incident diabetes, additively to age, BMI, CRP, HDL-cholesterol among Turks. Systemic inflammation concomitant with prevailing MetS might turn apoA-I into proinflammatory particles.

Abstract
To evaluate significant caries (SiC) index values and related factors in Turkish children aged 5-6 years old, children from 5 nursery schools in Istanbul were included in a cross-sectional study. Sociodemographic information and data about oral care habits were obtained from the records and from parents. Of 542 students examined, the mean decayed/missing/filled primary teeth (dmft) index was 3.74 (SD 3.49) and the SiC index was 7.75 (SD 2.56). About 76.8% of the children had experienced dental caries. Logistic regression analysis of the SiC index for dmft showed that risk factors for poor dental status were low mother's education (OR 2.04) and irregular toothbrushing versus once-a-day brushing (OR 4.09) or twice-a-day brushing (OR 4.20).

Abstract
In order to investigate the effect of kefir consumption on mucositis induced by 5-FU based chemotherapy (CT), we monitored the systemic immune response by measurement of the serum proinflammatory cytokine levels and we evaluated the anti-microbial effect of kefir with an agar diffusion method. Forty patients with colorectal cancer were included in this randomized prospective study. On the first 5 days of each CT cycle, the study group received oral lavage with kefir and then swallowed 250 ml of kefir while control group received oral lavage with 0.09% NaCl twice a day. Before and after every cycle of CT, the oral mucosa was assessed. Serum proinflammatory cytokine levels were evaluated before the initiation and after the third and the sixth cycle. Kefir was administered in 99 out of 205 courses. Mucositis developed in 27.3% of the courses given with kefir administration and in 21.7% of the courses given with 0.9% NaCl oral rinses. The difference between the two groups was not statistically significant (p > 0.05). When we compared the serum proinflammatory cytokine levels of the two groups at the baseline and following the third and the sixth cycles, we again found no statistically significant difference (p > 0.05). Kefir consumption at the mentioned doses made no statistically significant effect on serum proinflammatory cytokine levels and on the incidence of mucositis development in cancer patients. Under in vitro conditions, kefir inhibits only Staphylococcus epidermidis.
