BACKGROUND Inflammatory hematological parameters like the neutrophil/lymphocyte (N/L) ratio have been investigated in many cancer types and significant relationships found with prognosis, for example. The aim of this present study was to investigate the impact of hematological parameters notably on N/L ratio and mean platelet volume (MPV) in papillary thyroid cancer cases. MATERIALS AND METHODS A total of 79 patients who underwent a thyroidectomy operation in Findikli, Goiter Research and Treatment Center during 2011- 2015 period were enrolled in the study, 41 with papillary thyroid cancer and 38 with benign goiter confirmed by pathological examination. We collected clinical and laboratory data for the patients from hospital records retrospectively. Blood samples taken at admission were assessed for parameters compared between the groups. RESULTS No significant differences between papillary thyroid cancer and benign goiter groups were apparent in terms of age, the N/L ratio, MPV, white blood cell count (WBC), red blood cell count (RBC), hemoglobin, hematocrit, platelet, neutrophil, lymphocyte, red blood cell distribution width (RDW) and platelet crit (PCT) levels (>0.05). Only the level of platelet distribution width (PDW) significantly differed, being lower in the papillary cancer group (<0.05). CONCLUSIONS No significant relationship between papillary thyroid cancer and inflammatory hematological parameters including in particular the N/L ratio and MPV. The relevance of the PDW values remains unclear.

BACKGROUND Carotid artery stenting (CAS) is currently used as an alternative treatment to carotid endarterectomy (CEA). The objective of this study was to analyse our 5-year experience performing CAS. Secondarily, we sought to determine independent risk factors which predict periprocedural complications. PATIENTS AND METHODS A total of 146 patients who underwent 153 CAS procedures were analysed. The majority of patients (123, 84.2%) had symptomatic carotid stenosis. Demographic and interventional data, angiographic lesion characteristics, and periprocedural complications were recorded. Using univariate and multivariate logistic regression analyses, risk factors associated with adverse clinical outcomes were determined. RESULTS Periprocedural neurological complications, including four (2.7 %) major strokes, three (2 %) transient ischaemic attacks, one (0.7%) amaurosis fugax, and two (1.3 %) cases of hyperperfusion syndrome occurred in ten (6.8%) patients. The incidence of periprocedural complications significantly increased in female patients (r = 0.214, p = 0.009) and patients with longer lesions (r = 0.183, p = 0.027), contralateral stenosis ≥50 % (r = 0.222, p = 0.007), the presence of complicated plaques (r = 0.478, p < 0.001) and inadequate glycaemic control (r = 0.259, p = 0.002). Multivariate regression analysis also determined four variables to be potential independent risk factors for 30-day adverse events: higher age (Odds ratio [OR] = 1.283; 95 % CI, 1.051 to 1.566, p = 0.014); longer lesions (OR = 1.459, 95 % CI, 1.124 to 1.893, p = 0.004); higher tortuosity index (OR = 1.015, 95 % CI, 1.001 to 1.030, p = 0.034), and the presence of complicated plaque morphology (OR = 4.321, 95 % CI, 1.621 to 10.23, p = 0.001). CONCLUSIONS Patient and lesion characteristics including age, lesion length, complicated plaque morphology and tortuosity index, may be associated with periprocedural complications.

Carotid artery stenosis (CAS) is primarily caused by atherosclerotic plaque. Progressive inflammation may contribute to the rupture of an atherosclerotic plaque. The platelet‐to‐lymphocyte ratio (PLR) is a new and simple marker that indicates inflammation. In this study, we aimed to investigate the use of the PLR to determine the severity of CAS. One hundred forty patients were chosen from among patients who underwent carotid angiography in our institution. Symptomatic patients with stenosis >50% in the carotid arteries and asymptomatic patients with stenosis >80% were diagnosed via carotid angiography as having critical stenosis. Patients were classified into two groups. Group 1 included patients who had critical CAS, whereas Group 2 included patients with noncritical CAS, as determined by carotid angiography. Correlations between the PLR and the severity of CAS were analyzed. There were no significant differences in sex and age between the two groups. The PLR was 162.5 ± 84.7 in the noncritical CAS group patients and 94.9 ± 60.3 in the critical CAS group patients (p < 0.0001). The PLR value of 117.1 had 89% sensitivity and 68% specificity for CAS [95% confidence interval, 0.043–0.159; area under the curve, 0.101 ± 0.03)]. In this study, we have shown that PLR values may be associated with critical stenosis in at least one of the carotid arteries. Furthermore, PLR values may be used to predict critical stenosis in the carotid arteries.

Background: Osteoporosis affects quality of life (QoL) and may lead to depression in women. The purpose of this study was to evaluate the effects of zoledronic acid (ZA) treatment on depression and QoL in women with postmenopausal osteoporosis (PO). Materials and Methods: A total of 88 newly diagnosed women with PO were included in this study. All patients were treated with once-yearly ZA (5 mg). A QoL questionnaire from the European Foundation for Osteoporosis and Beck Depression Inventory were given to patients at baseline and at 12 months. The results for baseline and post - 12th month were compared, and bone mineral density (BMD) levels were compared. Results: The consumption of once-yearly ZA (5 mg) treatment increases BMD at levels of lumbers 1–4 (P = 0.026), total Hip T scores P value is same as femoral neck (P: 0,033). ZA 5 mg treatment also improved QoL (P = 0.001) and reduced depression (P = 0.001). Conclusion: ZA treatment increases BMD levels and QoL while reducing depression. Once-yearly ZA (5 mg) may be considered for postmenopausal women as a first-line treatment.

BACKGROUND CHA2DS2-VASc score is the most widely preferred method for prediction of stroke risk in patients with atrial fibrillation. We hypothesized that CHA2DS2-VASc score may represent atrial remodeling status, and therefore echocardiographic evaluation of left atrial electromechanical remodeling can be used to identify patients with high risk. METHODS A total of 65 patients who had documented diagnosis of paroxysmal atrial fibrillation (PAF) were divided into three risk groups according to the CHA2DS2-VASc score: patients with low risk (score=0, group 1), with moderate risk (score=1, group 2), and with high risk score (score ≥2, group 3). We compared groups according to atrial electromechanical intervals and left atrium mechanical functions. RESULTS Atrial electromechanical intervals including inter-atrial and intra-atrial electromechanical delay were not different between groups. However, parameters reflecting atrial mechanical functions including LA phasic volumes (Vmax, Vmin and Vp) were significantly higher in groups 2 and 3 compared with group 1. Likewise, LA passive emptying volume (LATEV) in the groups 2 and 3 was significantly higher than low-risk group (14.12±8.13ml/m(2), 22.36±8.78ml/m(2), 22.89±7.23ml/m(2), p: 0.031). Univariate analysis demonstrated that Vmax, Vmin and Vp were significantly correlated with CHA2DS2-VASc score (r=0.428, r=0.456, r=0.451 and p<0.001). Also, LATEV (r=0.397, p=0.016) and LA active emptying volume (LAAEV) (r=0.281, p=0.023) were positively correlated with CHA2DS2-VASc score. In the ROC analysis, Vmin≥11ml/m(2) has the highest predictive value for CHA2DS2-VASc score ≥2 (88% sensitivity and 89% specificity; ROC area 0.88, p<0.001, CI [0.76-0.99]). CONCLUSION Echocardiographic evaluation of left atrial electromechanical function might represent a useful method to identify patients with high risk.

The correlation between plasma D-dimer level and reperfusion has not been clarified yet in thrombolytic therapy applied for acute myocardial infarction patients. The aim of this study was to investigate whether there is a relationship between reperfusion and fibrinolytic activity in acute myocardial infarction patients treated with thrombolytic therapy. Fibrinolytic activity was reflected by plasma D-dimer levels. During the study period, 186 patients were initially analyzed. But 18 of these patients were excluded from the study because they were not suitable for study criteria. Blood was collected from 168 acute myocardial infarction patients within first 6 h. Intravenous tissue plasminogen activator (100 mg) or streptokinase (1 500 000 U) was applied to patients. Mean age of the patients was 58 (28–86) years and majority was men (86%). The number of anterior, inferior, and lateral myocardial infarction patients were 76 (45.2%), 85 (50.6%), and seven (4.2%), respectively. The mean time from symptom onset to thrombolytic application was 134 (95–212) min. Reperfusion occurred in 115 (68.5%) patients. D-dimer levels were markedly high after thrombolytic therapy versus before (155 mg/dl, 362 mg/dl, P <0.005). We compared the D-dimer values before and after thrombolytic therapy between reperfused group and the nonreperfused group (189–409 mg/l in reperfused group, P = 0.086; 82–258 mg/l in the nonreperfused group, P = 0.173). In conclusion, in this study, D-dimer levels were elevated markedly in patients with ST elevation myocardial infarction after thrombolytic therapy, but no significant difference was seen in D-dimer levels between the reperfused and nonreperfused groups.

AIM: This study aimed to evaluate the cardiac autonomic dysfunction and the cardiac arrhythmia risk using heart rate variability parameters in subjects with vitamin D deficiency and low cardiovascular risk. MATERIAL AND METHODS: One hundred five consecutive individuals, 54 patients with low vitamin D status and 51 healthy controls were enrolled in this study. The overall cardiac autonomic tone was quantified by using various heart rate variability parameters included mean RR interval, mean Heart Rate, mean of standard deviations of intervals for 24 hours (SDNN), standard deviation of averages of intervals (SDANN), mean of standard deviation of intervals for 5 minutes (SDNNI), root mean square of difference of successive intervals (rMSSD) and the proportion of intervals differing more than 50 ms (pNN50) values. The 12-lead ECG was recorded from each participant, and QT intervals were measured. RESULTS: Baseline demographic profiles were similar between two groups. The heart rate variability parameters such as mean RR interval, mean HR, SDNN, SDANN, SDNNI, rMSSD and pNN50 (%) values were not significantly different in patients with low vitamin D status compared to control group. The electrocardiography analysis revealed only slight but significant prolongation of corrected QT (QTc) intervals in the control group. CONCLUSION: HRV variables were not significantly altered in patients with vitamin D deficiency in low cardiovascular risk profile group. Further studies evaluating these findings in other cohorts with high cardiovascular risk are required.

INTRODUCTION Restless legs syndrome (RLS), also known as Willis-Ekbom disease, is characterised by abnormal sensations in the legs as well as dysaesthesia. Although the aetiology of RLS has not yet been determined, it may be associated with systemic inflammation. The neutrophil-to-lymphocyte ratio (NLR) is a new and simple marker indicating systemic inflammation. The present study aimed to investigate the relationship between systemic inflammation and RLS through the use of the NLR. METHODS A total of 75 newly diagnosed patients with RLS and 56 healthy control subjects were included in the study. Baseline NLR was calculated by dividing the absolute neutrophil count by the absolute lymphocyte count. The NLRs of the two groups were compared. RESULTS There were no significant differences in gender and age between the two groups. The NLR was 1.96 ± 0.66 in the patient group and 1.67 ± 0.68 in the control group (p = 0.005). Receiver operating characteristic analysis was performed to determine the cut-off value of NLR to predict RLS. The NLR was predictive at 1.58 with a 64% sensitivity and 50% specificity (95% confidence interval 0.55-0.74, area under curve 0.648 ± 0.05). The NLR was found to be statistically higher in patients with RLS and may be used to predict RLS. CONCLUSION The aetiology of RLS remains undetermined. The present study showed that systemic inflammation may play a role in RLS. However, RLS could also be associated with systemic inflammatory diseases. This relationship is supported by high NLR values, which are related to chronic systemic inflammation.

Background and Objective: Diagnostic performance of troponin assays is affected by renal insufficiency. Neutrophil to lymphocyte ratio(NLR) is an independent predictor of acute coronary syndrome. Our objective was to evaluate performance of NLR in diagnosing acute myocardial infarction (AMI) among patients with elevated serum creatinine. Methods: Patients with elevated creatinine levels evaluated for coronary artery disease were included (n=284). Patients were divided into two groups according to having AMI or non-specific chest pain. AMI diagnosis was made based on clinical and laboratory data, including serial EKG and cardiac enzymes, ECHO and coronary angiography. Results: Troponin, neutrophil, and NLR were found to be higher in patients with AMI, compared to patients without AMI (P= 0.001, P= 0.001 and P=0.028, respectively). ROC curve analysis for NLR in diagnosing AMI was significant (AUC: 0.607; P=0.003). Sensitivity, specificity, LR +, LR-, PPV and NPV for NLR>7.4 were found as 42.3%, 74.7%, 1.68%, 0.77%, 77% and 40%, respectively. Logistic regression analysis revealed that patients whose NLR>7.4 were 2.18 times as likely to have AMI. Conclusions: NLR can be used as an independent predictor of AMI in patients with renal insufficiency. This seems to get more important in the era of high sensitivity troponin assays. Our results might also help in early diagnosis of AMI in this high risk population while serial cardiac enzyme results are pending.

In this study, the prevalence and characteristics of definite migraine in primary restless legs syndrome (pRLS) patients and matched control patients (CPs) were investigated. We evaluated 63 consecutive adult pRLS patients and 141 age‐ and sex‐matched controls in this case–control study. The diagnosis of migraine and its subtypes were defined based on The International Classification of Headache Disorders‐II. Only those with “definite” migraine were included in the study. The mean age of 63 adult pRLS patients (15 men and 48 women) who participated in the study was 49.4 years. A total of 27 patients (42.9%) had definite migraine. Of these migraineurs, seven (11.1%) were without aura and 20 (31.8%) were with aura. The mean age of the 141 matched CPs was 48.7 years. A total of 32 CPs (22.7%) experienced migraine. Among these 32 migraineurs, 28 (19.9%) were without aura and four (2.8%) were with aura. Migraine and migraine with aura were significantly more common in pRLS patients than in CPs. pRLS patients with migraine were more anxious and experienced a shorter duration of RLS symptoms than pRLS patients without migraine. Migraineurs in the pRLS group tended to have high scores for severity of migraine headache by Visual Analog Scale score and high levels of disability by Migraine Disability Assessment grading than those in the control group. pRLS patients showed a positive association with definite migraine headaches. In contrast to results highlighted in recent studies, we found a strong link between migraine with aura and pRLS.
