Objectives: The aim of the present study was to evaluate the antioxidant effect of systemically administered caffeic acid phenethyl ester (CAPE) in periodontitis. Materials and methods: Forty rats were randomly divided into four groups: control, lipopolysaccharide-induced experimental periodontitis (LPS), CAPE 5: LPS+5 μmol/kg/day CAPE, and CAPE 10: LPS+10 μmol/kg/day CAPE. Following lipopolysaccharide-induced experimental periodontitis, CAPE was administered intraperitoneally for 28 days. Gingival and serumal total antioxidant status (TAS) and total oxidant status (TOS) were analyzed by enzyme-linked immunosorbent assay (ELISA). Results: Gingival tissue TAS was significantly higher with CAPE application compared with the LPS group and was highest in the CAPE 10 group (p

WOS:000529333500019 Our study was conducted to determinethe role of parental smoking status on the European Medical Association Smoking or Health (EMASH) nicotine dependence scores. Records of patients aged >= 18. registered at the Smoking Cessation Outpatient Clinics, were reviewed. Data of three groups (group 1: mothers' smoking status; group 2: fathers' smoking status; group 3: both parents' smoking status) were compared. A total of 902 patient records were analyzed (54.8% male, 45.2% female, age: 43.79 +/- 12.47 years). The average number of cigarettes smoked was 23.98 +/- 9.94/day, and the age of smoking onset was 19.11 +/- 5.94 years. There were more individuals with low EMASH score in the subgroup in which mothers did not smoke than that where mothers smoked (p=0.038). The percentage of females was higher (p=0.018) and the average age was lower (p=0.005) in that where mothers smoked. There were more individuals with high EMASH score in the subgroup in which fathers smoked than that where fathers did not smoke (p=0.026). There were more individuals with low EMASH score in the subgroup in which none of the parents smoked than that where both parents smoked (p=0.013). We found a strong relationship between smoking patterns and parental smoking. Smoking Cessation Clinic We would like to thank all the staff (nurses, secretaries) who had helped in the organization of the Smoking Cessation Clinic. We are grateful for the support and guidance offered by the Ethical Committee of Istanbul Medical Faculty.

Urticaria, also known colloquially as hives, is a vascular reaction characterized by itchy, edematous plaques and papules, which develops by immunological or non-immunological mechanisms after the exposure to a triggering stimulant. Painless and itchy lesions that blanch upon pressure and fade spontaneously within 48 hours are the characteristic feature of the condition. In the case of urticarial vasculitis, on the other hand, the plaques, which last for at least 24 hours and present with burning, pain, and itching, leave a pigmentation behind when fading, and exhibit the histopathological characteristics of leukoclastic vasculitis. Urticarial vasculitis, which constitutes 5-20% of all chronic urticaria cases, is more common in the fourth decade of life and women.

Background Acute ischemic stroke (AIS) is characterized as a neurological deficit owing to an acute focal damage to the brain by cerebral infarction. A collateral score is the most significant factor evaluating the prognosis of AIS, its relationship with demographic data, serum biochemical parameters, and clinical disability in this field. Purpose Our research aims to examine the relationship between collateral score (CS) and biochemical parameters and clinical disability in patients with AIS with M1 occlusion in the middle cerebral artery (MCA). Materials and methods We conducted a single-center retrospective study with 100 patients with AIS who are in the first 6 hours of ischemic stroke. Data for consecutive AIS patients were collected from February 2019 to May 2020. The collateral score was assessed by using developed scoring systems defined by Maas et al. The correlations between collateral score and demographic data, biochemical parameters, NIHSS scores (National Institutes of Health Stroke Scale), mRS (modified Rankin scale) scores were recorded. Results The research was performed in 100 patients (median age, 71.55±11.46 years) and there was a statistically significant difference between elevated erythrocyte distribution width (RDW) and Maas collateral score (insular cortex) (p= 0.024) and lymphocyte/monocyte ratio (LMO) and Maas collateral (leptomeningeal) score (p = 0.025). Conclusion In patients with acute MCA M1 occlusion, our analysis found a significant association between elevated RDW, low LMO parameters and collateral score. We assume that in terms of simple and quick usability in acute stroke prognosis, these parameters are useful and functional as a new biomarker.

In organ or non-organ-specific autoimmune disorders, human ovary is usually the target of the autoimmune attack. We aimed to demonstrate the correlation between ovarian reserve and DM1, based on the view that women with type-1 diabetes mellitus (DM1) will have lower AMH levels secondary to poor glycemic control and autoimmune attacks. Ovarian functions of 42 patients diagnosed with DM1 who use insulin and 65 healthy volunteers were analyzed. Basal hormone and AMH levels were measured during the follicular phase. Fasting and postprandial blood glucose concentrations, HbA1c and C-peptide levels were evaluated. The mean antral follicle count (AFC) was significantly lower in DM1 patients than in healthy controls (

Background Both the extracellular matrix molecule tenascin-C (Tn-C) and tissue inhibitors of metalloproteinases (TIMPs) have a role in tissue injury, inflammation, and remodeling. In this pilot study, we tried to evaluate the role of these markers in acute kidney injury (AKI). Methods A total of 52 subjects were enrolled in this study. Group 1 consisted of 27 patients with AKI (stage 1, 2, and 3), and Group 2 consisted of 25 age- and gender-matched healthy subjects. Serum and urine samples (to determine Tn-C and TIMP-1) were obtained from the participants at the beginning of the study. Second samples were obtained from Group 1 patients when renal function improved (at discharge). Results Serum TIMP-1 concentrations (admission and discharge) were higher in Group 1 than Group 2 (p = 0.0001 for both comparisons). Tn-C excretion in spot urine was significantly higher in healthy controls than at the admission levels of the patient group (p = 0.036). However, TIMP-1 excretion in spot urine was lower in healthy controls than in admission and discharge levels of the patient group (p = 0.0001 for both comparisons). Conclusions Our results show that these biomarkers (especially TIMP-1) may have a role in the pathophysiology of AKI. Further studies are needed in this field.

Objectives Warfarin is the most frequently used therapy as an oral anticoagulant medication for reducing the risk of thromboembolic complications. However, poor adherence to therapy may cause ineffective INR levels with increased complication risk. In our study, we aimed to show the rates of INR awareness of patients with atrial fibrillation (AF) using warfarin and whether they achieved the targeted INR values. Methods In this study, 300 male (60%, n=180) and female (40%, n=120) patients over 18 years of age who applied to warfarin polyclinic and were receiving warfarin treatment due to AF were included. The levels of INR between 2-3 were estimated as effective. Same questionnaire was applied to all patients. Results Our study showed that 57% of the patients who used warfarin were not in the therapeutic range. We also determined that INR awareness was extremely low in the majority of the patients. In this study, 72.2% of the patients who used warfarin did not know the definition of INR, 68% of the patients did not know the side effects of the medicine, 75.7% of the patients did not know the precautions needed to be taken in daily life and 83.7% of the patients did not know the foods rich in vitamin K. Patients who knew the meaning of INR were more likely have INR levels in the effective range, but these rates were not statistically significant. There was no statistically significant relationship between the educational level, marital status, and INR control frequency of the patients with the achievement of targeted INR levels. Conclusion At the beginning of the warfarin treatment, advantages and disadvantages should be balanced by the doctor. The patient and patient's relatives should be informed directly and comprehensibly about the effects and side effects of the medicine, as well as the interactions, pursuance and precautions need to be taken in daily life. Various modern methods should be enabled for surveillance and the patients who are not in the therapeutic range should be followed closer.

TUNCEL, OZGUR KORHAN/0000-0002-2989-5894 WOS: 000399263300018 PubMed: 28367895 Osteoporosis and periodontal disease are linked by an altered receptor activator of nuclear factor B-K ligand and osteoprotegerin ratio (RANKL/OPG), and medical treatment with bisphosphonate (BP) may help control these molecules. The effect of BP on clinical findings and gingival crevicular fluid (GCF) values of RANKL and OPG using enzyme-linked immunosorbent assays was evaluated in postmenopausal women; 13 patients with both chronic periodontitis and osteoporosis (group A), 12 systemically healthy patients with chronic periodontitis (group B), 12 periodontally healthy patients with osteoporosis (group C), and 10 systemically and periodontally healthy individuals (group D). Recordings were repeated at the end of months 1, 6, and 12 in groups A, B, and C. At the baseline, groups A and B exhibited the lowest OPG values (P < 0.05). After periodontal treatment, OPG values were markedly increased at the end of 6th month in group A and 12th month in group B (P < 0.008). There was no significant difference in GCF RANKL values among groups (P > 0.05) or during the observation period (P > 0.008). The use of BP may be effective in preventing periodontal breakdown by controlling the levels of these markers in osteoporosis as an adjunct to periodontal treatment.

OBJECTIVE This study aimed to evaluate the serum gamma-glutamyltransferase (GGT) levels as an indirect marker of elevated oxidative stress in patients with dilated ascending aorta. METHODS The study was designed as an observational cross-sectional controlled study. One hundred consecutive patients with dilated ascending aorta and 50 consecutive controls with normal ascending aorta diameter were selected for the study by comprehensive transthoracic echocardiography (TTE). The aortic dilatation group was divided into two subgroups, according to the literature as the ectasia group (3.8-4.3 cm, 53 patients, 24 male and 29 female, mean age: 62.9±10.9 years) and the aneurysm group (≥4.4 cm, 47 patients, 18 male and 29 female, mean age: 65.5±11.1 years). The control group consisted of patients demonstrating no ascending aorta dilatation (≤3.7 cm, 50 patients, 24 male and 26 female, mean age: 62.7±9.2 years). ANOVA, Mann-Whitney U test, Pearson's correlation analysis, multivariate logistic regression analysis, and receiver-operator curve analysis were used for statistical analysis. RESULTS Regarding the comparison of laboratory parameters between the patient and control groups, serum gamma-glutamyltransferase (GGT) levels were found to be statistically significantly higher in both of the aortic dilatation subgroups than in the control group (p

The risk for cardiovascular diseases and type 2 diabetes mellitus significantly increases in the patient population with metabolic syndrome (MeS). The present study aimed to investigate the association between the epicardial adipose tissue thickness (EATT) and the oxidative stress parameters in MeS patients. The study included 181 patients as a patient group of 92 consecutive patients with MeS and a control group of 89 consecutive patients with similar age and gender. EATT was evaluated by transthoracic echocardiography. Serum levels of total oxidant status (TOS), total antioxidative capacity (TAS), paraoxonase-1 (PON-1), and arylesterase activities were measured. EATT was higher in the MeS group compared to the control group (6.0 ± 2.0 mm and4.0 ± 1.0 mm, resp.;P<0.001). The level of TOS was higher in the MeS group compared to the control group (P<0.001). Additionally, the TAS level was higher in the MeS group compared to the control group (P<0.001). Furthermore, the serum levels of PON-1 and arylesterase were lower in the MeS group compared to the control group (P<0.001). EAT may cause an increased risk of cardiovascular diseases by leading to increased oxidative stress in patients with MeS.

Objective: We aimed to compare the levels of plasma zonulin, a non-invasive biomarker of increased intestinal permeability, between pregnant subjects, with and without gestational diabetes mellitus (GDM), at 24–28 gestational weeks. The eighty-five consecutive pregnant subjects that presented to our hospital’s obstetrics outpatient clinic and were diagnosed with GDM, for the first time by an oral glucose tolerance test (OGTT), formed the GDM group, 90 consecutive subjects that were not diagnosed with GDM by OGTT, formed the control group. The diagnosis of GDM was made by an OGTT performed between the 24th and 28th weeks of gestation, and in compliance with the American Diabetes Association (ADA) criteria. Plasma zonulin levels were measured by the enzyme-linked immunosorbent assay (ELISA) methods. The Plasma zonulin level was significantly higher in the GDM group than the control group (p &lt, 0.001). A correlation analysis showed that plasma zonulin level was positively correlated to body mass index (BMI), creatinine, fasting plasma glucose, baseline, first hour, and two hours glucose levels and the OGTT, hemoglobin A1C (HbA1C), homeostatic model assessment for insulin resistance (HOMA-IR), and alanine aminotransferase (ALT) levels. Our findings suggest that zonulin may be a non-invasive biomarker involved in the pathogenesis of GDM. Further large-scale studies are needed on this subject.

The aim of this study was to evaluate the serum soluble CD40 ligand (sCD40L) levels, serum uroten- sin II levels, and serum leptin levels as an indirect indicator of endothelial dysfunction, inflammation, and atherosclerosis at the microvascular level, and the comparison of those values with those of the control group with a nor- mal coronary flow pattern.The study included 35 consecutive patients (17 women, 18 men; average age: 51.20 ± 10.93 years) in our hospital who underwent coronary angiography due to objective myocardial ischemia and in whom slow coronary flow was detected. The control group included 34 consecutive patients with normal coronary flow pattern (18 women, 16 men; average age: 54.59 ± 12.40 years). The coronary flow rates of all patients and control subjects were documented by the thrombolysis in myocardial infarction (TIMI) frame count. Serum sCD40L concentrations, serum urotensin II concentrations and serum leptin concentrations were measured by an enzyme-linked immunosorbent assay method using commercially available kits.The corrected TIMI frame count for LAD, Cx, RCA, and mean TIMI frame count were significantly higher in patients with slow coronary flow (SCF), compared to subjects with normal coronary flow (43.8 ± 1.7 vs. 17.7 ± 4.7, p0.001; 27.9 ± 6.9 vs. 11.9 ± 4.8, p0.001; 25.4 ± 8.4 vs. 11.1 ± 3.1, p0.001; and 32.3 ± 6.4 vs. 13.7 ± 5, p0.001, respectively). The serum soluble CD40 ligand and serum urotensin II levels were significantly higher in the slow coronary flow group compared to the control group (12.00 ± 5.43 ng/mL--6.49 ± 5.03 ng/mL, p0.001; and 50.94 ± 34.28 pg/mL--26.91 ± 11.52 pg/mL, p0.001, respectively). In addition, there was no statistically significant difference between the slow coronary flow group and the control group with regard to serum leptin levels and hs-CRP levels (both p0.05).This study suggests that soluble CD40 ligand and urotensin II likely play a role in the pathogenesis of slow coronary flow.
