Abstract
OBJECTIVE The aim of this study was to investigate the prevalence of microvascular and macrovascular diabetic complications and the associated comorbidities in newly diagnosed pre-diabetic individuals. PATIENTS AND METHODS This cross-sectional study includes 100 newly diagnosed pre-diabetic individuals. Fasting plasma glucose, HbA1c, and oral glucose tolerance (OGTT) were tested according to the American Diabetes Association's diagnostic criteria for pre-diabetes, besides anthropometric measurements, lipid profiles, and demographic and biochemical parameters. Comorbidities like hypertension, obesity, dyslipidemia etc., were evaluated. All participants were screened for microvascular (retinopathy, nephropathy, neuropathy) and macrovascular [coronary artery disease (CAD) and cerebrovascular event-peripheral artery disease] complications. RESULTS Microvascular complications were found in 12% of the participants (neuropathy: 4%, nephropathy: 8%) and 19% had macrovascular complications. Of the participants, 21% of the cases presented hypertension, 21% dyslipidemia and 48% obesity. A high probability of developing non-alcoholic fatty liver disease-related fibrosis [estimated using non-alcoholic fatty liver disease fibrosis score (NFS)] was found in 68% of cases. History of dyslipidemia (OR: 5.00, 95% CI: 1.10-22.56; p=0.037) was an independent risk factor for the development of vascular complications. CONCLUSIONS Diabetic vascular complications were found in approximately one-third of pre-diabetic cases. Dyslipidaemia was found to be an important risk factor for the development of vascular complications in these individuals.

Abstract
Abstract
Background
There are many technical variations in carotid artery stenting and there is not a clear recommendation in pre-dilatation (Pre-D) prior to stenting. In this study we investigated the role of Pre-D before carotid artery stenting in patients with very severe carotid artery stenosis (≥90%).
Methods
A total of 298 patients with a carotid stenosis equal to or more than 90% were included to our study. Patients were divided into two groups as Pre-D and No-Pre-D. In-hospital and 3-year long-term clinical outcomes were compared between the groups.
Results
During the hospitalization, major stroke was more common in Pre-D group [n=6 (5.5%) vs. n=3 (1.5%), respectively], whereas overall ipsilateral stroke rates were similar between the groups. The rates of myocardial infarction were similar between the groups. In- hospital mortality was significantly higher in the Pre-D group than non-pre-D group [n=4 (3.6%) vs. n=0 (0%), respectively]. During the 3-year follow up period, the rates of ipsilateral stroke, major stroke, transient ischemic attack, myocardial infarction, and mortality were similar between the groups.
Conclusion
According to the literature, this is the first study evaluates the role of Pre-D in very severe (>90%) carotid artery stenosis. The current study demonstrated that Pre-D might have a detrimental effect on in-hospital outcomes.

Abstract
Abstract
Background
Inflammatory markers are significantly associated with cardiovascular disease and many markers have been used as predictor in patients with STEMI. This study examines the predictive value of the novel systemic immune-inflammation index (SII) in patients with ST-segment elevation myocardial infarction (STEMI).
Method
A total of 1660 patients with STEMI who underwent primary percutaneous coronary intervention in a tertiary heart center were enrolled in the study. SII was calculated using the following formula: Platelet × Neutrophil/Lymphocyte ratio. The patients were stratified into four quartiles (Q) according to admission SII level. In-hospital and 3-year outcomes were compared between the four groups (Q1–4)
Results
In-hospital cardiogenic shock, acute respiratory failure, acute kidney injury, ventricular arrhythmia, stent thrombosis, recurrent myocardial infarction, major adverse cardiac events, and mortality were significantly higher in the high SII groups (Q3 and Q4). Logistic regression models demonstrated that Q3 and Q4 had independent risk of mortality and Q4 had an independent risk of cardiogenic shock compared to Q1. ROC analysis showed that the best cut-off value of the Systemic Immune-Inflammatory Index to predict the in-hospital mortality was 1781 with 66% sensitivity and 74% specificity (AUC: 0.75; 95% CI: 0.69–0.81; p<0.001). Kaplan Meier overall survivals for Q1, Q2, Q3 and Q4 were 97.6%, 96.9%, 91.6% and 81.0% respectively. Cox proportional analysis for 3-year mortality demonstrated that Q3 and Q4 had independent risk of death compared to Q1.
Conclusion
SII, a novel inflammatory index, had a better prediction of in-hospital and long-term outcomes than traditional risk factors in patients with STEMI.

Abstract
Leishmaniasis is an arthropod-borne disease that affects approximately 2 million people worldwide annually. The aims of this study were to detect the presence of Leishmania (Kinetoplastida: Trypanosomatidae) DNA and the feeding preferences of probable vector species in an endemic focus of Leishmania infantum in Turkey. Entomological sampling was performed in August and October 2015 in Aydın province, where cases of human and canine leishmaniasis have been reported previously. A total of 1059 sandfly specimens comprising nine species belonging to two genera, Phlebotomus and Sergentomyia (both: Diptera: Psychodidae), and five subgenera of the Phlebotomus genus (Phlebotomus, Paraphlebotomus, Larroussius, Adlerius and Transphlebotomus) were collected in five villages. Among all Phlebotomus specimens, Phlebotomus neglectus (39%) was noted as the most abundant species, followed by Phlebotomus tobbi (18%). Leishmania DNA was detected in pools from P. neglectus, P. tobbi and Sergentomyia dentata by kDNA polymerase chain reaction (PCR). Leishmania DNA from Phlebotomus specimens was identified as L. infantum, but Leishmania DNA from Sergentomyia spp. could not be identified to species level by ITS-1 real-time PCR. The detection of Leishmania DNA in wild-caught P. neglectus and the high percentage (24.2%) of human DNA in engorged specimens suggests that P. neglectus is probably an important vector species for L. infantum in Aydın province.

Abstract
OBJECTIVE To compare our laparoscopic simple nephrectomy results in non-functioning inflammatory kidneys with or without renal stones. PATIENTS AND METHODS Patients, who underwent laparoscopic transperitoneal nephrectomy for non-functioning kidney between June, 2010 and October, 2014 were included to study. Overall, data of 32 patients including 15 patients with renal stone (Group 1) and 17 patients without renal stone (Group 2) were retrospectively reviewed. RESULTS Mean age was 44.4 ± 18.5 years (10-71) in group 1 and 35.2 ± 21 years (9-77) in group 2. Mean operation time was 95.0±25.9 minutes (70-175) in group 1 and 86.7 ± 15.1 minutes (70-125) in group 2. Mean estimated blood loss was found to be 64.13 ± 26.67 ml (30-120) in group 1 and 58.94 ± 24.24 ml (30-100) in group 2. Both groups had inflammatory findings in pathological analysis. There was no significant difference between groups regarding estimated blood loss, operation time, pre-operative and post-operative hemoglobin values, percent hemoglobin decrease, complications and hospitalization times (p > 0.05). CONCLUSIONS Non-functioning kidney with or without renal stone could be operated safely with comparable complication rates and success via laparoscopy in experienced hands.

Abstract
OBJECTIVES To investigate the accuracy of cone beam CT (CBCT) images obtained with and without artefact reduction (AR) in detecting simulated buccal peri-implant and buccal periodontal defects. METHODS 42 implants inserted into edentulous mandibles, and 38 teeth present in dry mandibles were used. Simulated buccal peri-implant defects (n = 22) and buccal periodontal defects (n = 22) were prepared. 20 implants and 18 teeth without simulated defects were the control group. Images of the mandibles were obtained using a Planmeca ProMax(®) 3D Max CBCT unit (Planmeca Oy, Helsinki, Finland). Image reconstructions were prepared without and with low, medium and high AR modes. Images were viewed randomly by six observers twice for the presence of defects. Kappa coefficient was calculated. F2_LD_F1 design for non-parametric analysis of longitudinal data was used. Area under curves (AUCs) were calculated for each observer. Significance level was taken as α = 0.05. RESULTS Intraobserver kappa ranged from 0.140 to 0.792 for peri-implant and from 0.189 to 1.0 for periodontal defects. All factors were statistically significant (p < 0.001), except for image mode and implant brand. Pairwise interactions were found between periodontal defects and peri-implant defects (p < 0.001), observers (p < 0.001), observer and image mode (p < 0.001), defect model and observer (p < 0.001) and defect model, image mode and observer (p = 0.04). AUC values ranged from 0.39 to 0.52 for peri-implant and from 0.45 to 0.71 for periodontal defects. Higher AUC values were found for periodontal defects than for peri-implant defects. CONCLUSIONS Buccal peri-implant defects were more difficult to detect than buccal periodontal defects. No difference was found among CBCT images obtained with and without AR modes.

Abstract
1. A herbal extract containing a blend of three essential oils, derived from oregano, laurel leaf and lavender, was investigated as a feed additive alternative to the conventional anticoccidial sodium monensin. 2. Broilers were infected with a mixture of Eimeria species or left uninfected. Both infected and uninfected broilers were provided with diets containing either herbal extract (HEX), monensin (MON) or without these supplements (CON). The HEX group had 50 mg herbal extract/kg diet and the MON group 100 mg monensin/kg diet. 3. All of the uninfected broilers exhibited higher body weight gain and better feed conversion when compared with their infected counterparts at d 28 and 42 of age. Both HEX and MON supplements caused significant improvements in performance in the infected broilers, but failed to have any effect on uninfected broilers. 4. Faecal oocyst output measured daily by sampling excreta, and expressed on a per bird basis, was lower in the HEX and MON groups than in the CON group. However, the herbal extract was not as effective as monensin in reducing oocyst excretion. Coccidial infection caused a significant increase in total intestinal length and caecal weight, but the dietary treatments did not influence these measurements. 5. These results indicate that providing a herbal extract in the diet was not as effective as monensin in protecting broilers exposed to a coccidial challenge.

Abstract
PURPOSE To report the incidence of choroidal detachment (CD) following trabeculectomy and to evaluate its effect on long-term surgical success and best-corrected visual acuity (BCVA). METHODS A total of 253 eyes of 198 subjects who underwent trabeculectomy between 1993 and 2003 with at least 1 year follow-up were reviewed retrospectively. Twenty-eight eyes of 28 subjects which developed CD postoperatively were classified as Group 1 and the remaining 225 eyes of 170 subjects as Group 2. The risk factors for the development of CD and the influence of CD on BCVA and on the success of trabeculectomy were analyzed and compared between the two groups. RESULTS In Group 1, preoperative BCVA was significantly lower and cup to disc ratio and the frequency of pseudoexfoliative glaucoma were higher with respect to the control group (p=0.009, p=0.01, p=0.02). The correlations between the development of CD and postoperative findings such as shallowing of the anterior chamber, hypotony, hypotonic maculopathy, hyphema, and fibrin reaction in the anterior chamber were statistically significant.CD was not associated with a significant reduction of BCVA. Intraocular pressures at postoperative first day, sixth month, and first year were lower in Group 1. The success of trabeculectomy and the average number of medications used were not significantly different between the two groups. CONCLUSIONS CD following trabeculectomy occurred in 11% of our patients. CD was not associated with either a significant drop in BCVA or an adverse influence on long-term IOP control.

Abstract
PURPOSE To present the authors' long-term experience of radial keratotomy (RK) for the optical rehabilitation of patients with mild to moderate keratoconus--central corneal thickness of greater than 400 microm and without apical scarring. METHODS In this observational, noncomparative series of cases, all consecutive patients with mild or moderate keratoconus, treated by RK between 1990 and 2002, with at least 1 year follow-up were included. A total of 170 eyes of 96 patients were investigated. Mean follow-up was 42.08 +/- 28.14 months. Visual acuity, refraction, corneal curvature, central corneal thickness, and complications were evaluated. RESULTS In all of the control visits, mean uncorrected and best spectacle corrected visual acuities were better than preoperative values (p<0.0001). Preoperative myopic spherical refraction decreased significantly (p<0.0001), and remained relatively unchanged throughout the follow-up (p=0.43). A small but statistically significant decrease from baseline was ob-served in astigmatism (p=0.038), which almost disappeared 1 year after the surgery (p=0.47). The surgery produced a statistically significant flattening of the corneal curvature (p<0.0001). Central corneal thickness did not change significantly (p>0.05) in either control visit. In 33 eyes (19.4%), re-deepening of the incisions was required. In 3 eyes (1.8%) penetrating keratoplasty was performed, due to disease progression in 2 eyes (1.2%) and acute traumatic hydrops in 1 eye (0.6%). In 4 eyes (2.2%) microperforation, in 2 eyes (1.2%) macroperforation, in 1 eye (0.6%) infectious keratitis, and in 1 eye (0.6%) hyperopic shift occurred. CONCLUSIONS RK surgery was found to be a reasonable option for the rehabilitation of a selected group of keratoconus patients in the early or moderate stages.

Abstract
An epidemiological survey for Theileria annulata infection was conducted in 12 selected villages around Ankara in Central Anatolia, Turkey, during the period April 1990 to January 1993. During the survey, 198 cattle of 30 local breeds, 84 Holstein-Friesian x local breeds and 84 Holstein-Friesian breed were examined for antibodies to T. annulata and the presence of the vector ticks. Four species of Hyalomma ticks were identified: Hyalomma anatolicum anatolicum, Hyalomma anatolicum excavtum, Hyalomma detritum and Hyalomma marginatum marginatum. Salivary gland staining indicated that infected adult ticks of all four species were present and, therefore, were implicated in the transmission of tropical theileriosis in the field. Generally, the Hyalomma infestation rate was low, with the heaviest infestations occurring on the older animals. Young adults and calves had very low infestation rates. Most ticks seen on cattle were adults, very few nymphs were found. The blood smear and serological examination of the 198 cattle conducted in March, before the start of the first disease season, showed that the prevalence of piroplasmosis was 11.1% (22 out of 198) and the seroprevalence of T. annulata was 10.6% (21 out of 198). Forty-three animals were then excluded from the study because they were seropositive and/or harboured piroplasms. Ninety-two seronegative animals showed piroplasmosis (92 out of 155) and 34 seronegative animals became seropositive for T. annulata (34 out of 155) during the three disease seasons. One animal became clinically ill with tropical theileriosis and required treatment. The incidence of cattle showing piroplasmosis and disease in the total study sample was 50.7% and 0.5% per disease season, respectively. The seroconversion rate of new infection with T. annulata in the total study was 14.3% per animal season. The number of cattle showing piroplasmosis was much greater than the number of seropositive cattle, which may indicate the presence of another species of Theileria. The two different management systems encountered in the study were considered to have influenced the tick infestation levels.

Abstract
In this comparative study unfed nymphs of four Hyalomma tick species (Hyalomma anatolicum anatolicum, Hyalomma anatolicum excavatum, Hyalomma detritum and Hyalomma marginatum marginatum) were allowed to engorge on calves experimentally infected with Theileria annulata. The infection prevalence in the salivary glands of the adult female and male ticks of each Hyalomma species used in the study were assessed. The infection prevalence with T. annulata was high and did not vary markedly in the four Hyalomma tick species. The mean number of infected acini per tick in female and male ticks was different with female ticks having higher numbers of infected acini than the male ticks. The sex difference was more significant between H.a. anatolicum and H.a. excavatum than between H. detritum and H.m. marginatum. This study clarifies the roles of four Hyalomma tick species, and their sex, in the development of T. annulata.

Abstract
A serological survey using Indirect Fluorescent Antibody Test (IFAT) for Babesia ovis infection of sheep has been carried out in different geographical regions of Turkey. The results indicated that 71.6% of 141 sheep in Black Sea region, 70.9% of 93 sheep in central Anatolia, 80.2% of 96 sheep in Aegean region and 55.7% of 122 sheep in eastern Anatolia were seropositive. This means that B. ovis infection is endemic throughout Turkey. In addition, occurrence of B. ovis, B. motasi, Theileria hirci, T. recondita and Anaplasma ovis infections in sheep and goats has been reported previously in Turkey as well. However further studies are needed to obtain more information about the agents to keep the infection under control.
