Abstract
OBJECTIVE We determined whether U-shaped relationships exist between serum lipoprotein[Lp](a) and cardiometabolic risk. METHODS In population-based nondiabetic and diabetic middle-aged adults (n=1 428 and 241, respectively) who had been genotyped for the LPA rs10455872 A>G polymorphism, we adjusted the Lp(a) concentration for the effects of genotype and other covariates. Via sex-specific equations we estimated expected Lp(a) concentration in each participant, and the quotient between observed to expected Lp(a) values was determined. Lp(a) and Lp(a) quotient tertiles served to identify non-linear associations with outcomes. RESULTS Incident 81 cases of diabetes and 128 of coronary heart disease (CHD) developed at 5.1 years' follow-up. Lp(a) concentration was linearly associated with the LPA genotype, gender, total cholesterol, (inversely) fasting insulin, which together with age formed the variables to derive the equations. In logistic regression for incident diabetes, the low Lp(a) quotient tertile was a predictor (RR 1.95 [95%CI 1.10; 3.47]) alike the low Lp(a) tertile, additively to major confounders. Cox regression models comprising sex, age, LPA genotype, smoking status, systolic pressure and serum HDL-cholesterol disclosed that, compared with the mid-tertile, both low (HR 1.77) and high Lp(a) quotient tertiles significantly predicted incident CHD, especially in women. CONCLUSION Elevated cardiometabolic risk is conferred by apparently reduced circulating Lp(a) assays supporting the notion that "low" serum Lp(a), mediating autoimmune activation, is a major determinant of cardiometabolic risk.

Abstract
Early diagnosis and treatment in acute ischemic stroke are crucial in terms of survival and disability. Many stroke patients remain disabled because of the treatment delay. The purpose of this study was to investigate the factors associated with the early hospital arrival in acute ischemic stroke patients. 113 patients diagnosed with acute ischemic stroke were included in this prospective study performed at the Karadeniz Technical University Medical Faculty Hospital. Patients' characteristics and patients' and relatives' emotional and behavioral reactions were compared between early (within 3 h) and late (after 3 h) arrival groups. 72.6 % of patients arrived at hospital within 3 h from symptoms onset. Univariate analysis revealed that history of atrial fibrillation (p = 0.04) and coronary heart disease (p = 0.02), sudden onset of symptoms (p = 0.001), loss of consciousness (p = 0.03), recognizing symptoms as stroke (p = 0.01), seeking immediate medical attention (p < 0.001), feelings of fear and panic (p = 0.001), arriving at hospital by ambulance having called the emergency medical services (p = 0.04) and National Institute of Health Stroke Scale (NIHSS) score (p = 0.001) were associated with hospital arrival within 3 h. A multivariate regression model demonstrated that recognizing symptoms as stroke (OR, 3.4; 95 % CI, 1.2-9.3) and atrial fibrillation (OR, 4.3; 95 % CI, 1.1-15.7) were independent factors associated with early arrival. The role in early arrival at hospital of recognizing symptoms as stroke and seeking immediate medical attention with transportation by ambulance emphasize the importance of public awareness concerning recognizing the symptoms of stroke and accessing emergency medical assistance.

Abstract
PURPOSE Antiepileptic drugs have been reported to reduce the levels of serum immunoglobulins and affect the production and levels of certain cytokines. We investigated the effects of valproic acid (VPA) and topiramate (TPM) on the blood levels of interleukin (IL)-1α, IL-1β, IL-6, IL-10, and TNF-α in children with idiopathic generalized and partial epilepsy. METHODS Forty prepubertal children aged 6-12 (mean 8.3±1.7) years, 19/40 (47.5%) female and 21/40 (52.5%) male, with idiopathic generalized or partial epilepsy diagnosed in the child neurology outpatient clinic were included. The patients were divided into two treatment groups: 20 were treated with VPA and 20 with TPM. The plasma levels of IL-1α, IL-1β, IL-6, IL-10, TNF-α were measured using ELISA method before the initiation of treatment and at the 6th and 12th months of the treatment. The Chi-square test was used to compare qualitative data. To compare the periods, recurrence measurements were done using variance analysis and Freidman 2-sided variance analysis. p<0.05 was considered as statistically significant. RESULTS In the VPA group, the levels of IL-1α significantly increased at 12 months while the levels of IL-10 decreased at 6 months of treatment compared to values before treatment (p<0.05). There was no significant difference in levels of IL-1β, IL-6, TNF-α (p>0.05). In the TPM group, lower levels of IL-10 were observed at 6th and 12th months compared to the onset of treatment (p<0.05). CONCLUSION The results of this study demonstrated that VPA and TPM might lead to changes in the levels of cytokines in epileptic patients. The next step would be to investigate the relation of these findings to the outcome of epilepsy and response to treatment.

Abstract
OBJECTIVES The objectives of this article are to investigate the serum lipid hydroperoxide (LOOH) levels and paraoxonase-1 (PON1) and arylesterase (ARE) activity in patients with lung, breast, and colorectal cancer. DESIGN AND METHODS Serum PON1 and ARE activities and LOOH levels were measured in 110 patients with cancer and same number of age- and sex-matched controls. RESULTS Serum LOOH levels were found to be increased while serum PON1 and ARE activities were found to be decreased in patients compared to controls. PON1 activity was found to be lower in patients with breast cancer than in patients with lung and colorectal cancer. There were positive correlations between the serum PON1 and ARE activities in patients with colorectal cancer. CONCLUSION We concluded that decreased PON1 and ARE activities and increased LOOH levels might have a connection to carcinogenesis. PON1 activity is decreased in all patients but it does not seem to be related to metastase status except for colorectal cancer.

Abstract
BACKGROUND AND AIM An algorithm is needed for predicting coronary heart disease (CHD) risk in Turkish adults who have a high prevalence of metabolic syndrome (MetS). METHODS AND RESULTS Ten-year risk of CHD was estimated in 2232 middle-aged adults free of CHD at baseline, followed over 7.6-years. Cox proportional hazard regression was used to predict CHD. Discrimination was assessed with area under receiver operating characteristics curve (AROC). CHD developed in 302 subjects. In multivariable analysis, high-density lipoprotein (HDL)-cholesterol levels were borderline predictive in men; smoking status and HDL-and low-density lipoprotein (LDL)-cholesterol levels were not predictive in women. Age, presence of diabetes, systolic blood pressure and C-reactive protein (CRP) were predictors in both sexes, while smoking status and LDL-cholesterol were so in men only. AROC of the model was 0.789 in men, and 0.806 in women (p < 0.001 each). An algorithm using the stated seven variables was derived separately for each sex. After age adjustment, men and women in the highest quintile of risk score were significantly and 20-27-fold more likely to develop CHD than those in the lowest quintile. CONCLUSIONS In a population with prevalent MetS, low-grade inflammation is independently relevant for CHD, as are serum lipoproteins and smoking status. The derived algorithm is effective in estimating CHD risk among Turkish adults.

Abstract
OBJECTIVE This study was intended to investigate the clinical significance and molecular epidemiology of Acinetobacter baumannii complex (ABC) isolated from cerebrospinal fluid (CSF) in neurosurgical intensive care unit (NSICU) patients, particularly comparing isolates from healthcare workers' (HCW) hands. METHODS We retrospectively reviewed the medical records of 30 patients with CSF cultures positive for ABC seen at our NSICU from the date it first opened, January 2007, to September 2010. Pulsed-field gel electrophoresis (PFGE) typing was performed on 68 strains isolated from 32 patients' CSF and 36 HCWs' hands. RESULTS ABC isolates were considered to be clinically significant in 21 (70.0%) patients but insignificant in the other nine (30.0%) patients. The prolonged (>7 days) use of cephalosporins was more common in patients with clinically significant ABC isolates (p = 0.049). Multiple drug resistance (MDR) was observed in 12 (57.1%) clinically significant isolates. Empirical antimicrobial therapies were not appropriate for nine of these 21 patients (42.8%). Mortality was significantly higher in the clinically significant group than in the clinically insignificant group (18/21 vs. 3/9; p = 0.008). Fifty-three isolates (77.9%) were grouped into 15 clusters, three of which contained possibly related isolates from patients' CSF and staff members' hands. CONCLUSIONS The fact that ABC isolates grown from CSF cultures do not always exhibit infection and have high multiple antibiotic resistance, including to carbapenems, should be borne in mind when planning treatment for these patients. In addition, HCWs' hands may play a significant role in transmission to patients, and compliance with infection control procedures, especially hand washing, must be enhanced in order to avoid ABC infections.

Abstract
BACKGROUND AND AIM An algorithm for predicting Type 2 diabetes (DM) risk in a population with prevalent metabolic syndrome (MetS) is needed since ethnicity influences the pathogenesis of DM. MATERIAL AND METHODS The 8- yr risk of DM was estimated in 2261 middle-aged Turkish adults free of DM at baseline who were followed for over 7.6 yr. DM newly developed in 212 subjects. Cox proportional hazard regression and 15 variables were used to predict DM. Discrimination was assessed with area under receiver operating characteristics curve (AROC). RESULTS In multivariable analysis, height, family income brackets, systolic blood pressure, smoking status, alcohol usage, and HDL-cholesterol levels were not predictive in either sex. In addition to sex, family history of DM, fasting glucose, and waist circumference were predictors, in men, age and non-HDL-cholesterol, while in women physical inactivity and serum C-reactive protein were so. AROC of the final model was 0.783 in men, 0.772 in women (p<0.001 each). An algorithm using the stated 7 variables was developed separately for each sex. Men and women in the top quintile of risk score were, respectively, 20 and 50 times and significantly more likely to develop DM than those in the bottom quintile. The predictive value of the algorithm was validated in 2 split samples. CONCLUSIONS A marker of low grade inflammation provides useful predictive ability beyond other simple predictors in a female population with MetS prevailing. The derived simple algorithm may be useful in estimating the 8-yr risk of DM among middle-aged Turkish men and women.
