Abstract
We examined how different methods of surface treatment and different universal adhesives with or without extra silane affected the repair bonding strength of hybrid ceramic CAD/CAM restorations. Cerasmart specimens (n=320) were subjected to thermocycling and assigned to the following surface pretreatment protocols: control, diamond bur (DB), hydrofluoric acid (HF), and tribochemical silica coating (TSC). Half the specimens received a coating of silane, followed by application of the universal adhesives Futurabond M+ (FMU), Tokuyama Universal Bond (TUB), Single Bond Universal (SBU), or Clearfil Universal Bond Quick (CUQ) (n=10). A hybrid composite resin was used to simulate repair; then the specimens underwent further thermocycling. Shear bond strength (SBS) was determined and modes of failure were examined. The TSC-CUQ silane (-) group showed the highest SBS values. The best repairs were obtained when the surface was treated with TSC, with the exception of the DB-TUB silane (-) group. TUB increased SBS more than the other adhesives. Additional silane decreased SBS in the HF-TUB and TSC-CUQ groups, while increasing it in the TSC-TUB and DB-FMU groups (p<0.05).

Abstract
Background and Objectives: Chronic kidney disease (CKD) is a global public health issue with rising incidence linked to substantial morbidity and mortality. Selenium, an antioxidant trace element, has been linked to low serum levels in end-stage renal disease. Restless Leg Syndrome (RLS), a sleep disorder, is prevalent in CKD patients and significantly impacts their quality of life. The objective of this study was to examine the correlation between serum selenium levels and the prevalence of restless leg syndrome in individuals with chronic kidney disease. Materials and Methods: Forty-six CKD patients undergoing serum selenium level assessments between 1 January 2020 and 28 February 2022, at the Hitit University Faculty of Medicine Department of Nephrology Outpatient Clinic or Hemodialysis Unit, were included. Patients over 18 years of age with no history of hematological or oncological diseases or acute or chronic inflammatory conditions were included in the study groups. Patients taking selenium supplements were excluded. Demographic data, comorbidities, and laboratory values were collected, and RLS presence and severity were evaluated. Statistical analyses include descriptive statistics, correlation analysis, the Mann-Whitney U test, Student's t test, and Chi-square test. Results: Among the 46 patients, 16 (34.78%) had RLS symptoms. The patient group included 34.78% predialysis, 34.78% peritoneal dialysis, and 30.44% hemodialysis patients, with a median age of 47.98 years. There was no difference in age, gender, and Charlson comorbidity between patients with or without RLS (p = 0.881, p = 0.702, p = 0.650). RLS prevalence varied across CKD subgroups, with hemodialysis patients having a higher prevalence (p = 0.036). Clinical parameters such as blood urea nitrogen, creatinine, calcium, phosphorus, platelet counts, and parathyroid hormone levels exhibited significant differences between patients with and without RLS (p < 0.05). Serum selenium levels were not significantly different between patients with and without RLS (p = 0.327). Conclusions: With an increased comorbidity burden, CKD poses a significant healthcare challenge. When accompanied by RLS, this burden can be debilitating. The difference in CKD stages between groups has shed light on a critical determinant of RLS in this population, emphasizing the role of the chronic kidney disease stage. In our study, serum selenium levels were not associated with the presence and severity of RLS. However, prospective studies with larger numbers of participants are needed to draw a definitive conclusion.

Abstract
Objectives
This study aims to investigate the point prevalence of fibromyalgia in patients on hemodialysis and peritoneal dialysis and after renal transplantation compared to healthy controls and to evaluate depressive symptoms, anxiety level, and the impact of fibromyalgia on quality of life (QoL). Patients and methods
Between January 2018 and January 2019, a total of 107 hemodialysis patients (Group 1) (48 males, 59 females; median age: 50 years; range, 42 to 56 years), 51 peritoneal dialysis patients (Group 2) (32 males, 19 females; median age: 49 years; range, 39 to 54 years), 52 renal transplant patients (Group 3) (23 males, 29 females; median age: 45.5 years; range, 37 to 52 years), and 50 healthy controls (Group 4) (23 males, 27 females; median age: 46.5 years; range, 42 to 50 years) were included in the study. Age, sex, amount of time spent on dialysis, and laboratory data were recorded. Impact of fibromyalgia on QoL was evaluated using the Fibromyalgia Impact Questionnaire (FIQ), while depressive symptoms and anxiety level were assessed using the Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI), respectively. Results
The point prevalence of fibromyalgia was 14% in Group 1 (n=15), 5.9% in Group 2 (n=3), 9.6% in Group 3 (n=5), and 4% in Group 4. There was a significant difference in the point prevalence of fibromyalgia between the hemodialysis group and healthy controls (p<0.05). The median FIQ scores were significantly higher in all patient groups than Group 4 (p<0.001); however, there was no significant difference between the patient groups (p>0.05). The median BDI scores were significantly higher in Group 1 and Group 2 than Group 4 (p<0.05). The median BAI scores were significantly higher in Group 1 than Group 4 (p<0.05). When the patients with and without fibromyalgia were compared, FIQ and BAI in Group 1, BAI in Group 2, and FIQ in Group 3 significantly differed (p<0.05). There was no relationship between fibromyalgia and any of the laboratory data, age, or time spent on dialysis (p>0.05). Conclusion
Fibromyalgia is significantly more common among hemodialysis patients than healthy individuals with a similar prevalence to the healthy individuals for peritoneal dialysis and renal transplant patients. The presence of fibromyalgia is related to depressive symptoms, anxiety, and higher impact on QoL for patients with chronic kidney disease.

Abstract
Background Current evidence indicates that vascular calcification plays an essential role in the development of cardiovascular diseases in end-stage renal disease (ESRD) patients. Arterial stiffness is a marker of increased cardiovascular risk in various populations. The aim of this study is to evaluate the elastic properties of ascending aorta in patients with ESRD. Methods This single-center study enrolled 96 patients (45 females, age: 57.2 ± 12.8 years) with ESRD and 96 healthy controls (52 females, age: 55.3 ± 10.1 years). Aortic pressures and aortic elastic parameters including aortic strain, aortic distensibility, aortic stiffness index, and aortic compliance were calculated using accepted formulae. Results The hemodynamic parameters including aortic pulse pressure, aortic mean pressure, aortic fractional pulse pressure, and aortic pulsatility index were significantly higher in patients with ESRD. Systolic and diastolic aortic diameters were similar between the groups. However, pulsatile aortic diameter change, aortic strain, aortic distensibility, and aortic compliance were significantly lower, whereas aortic stiffness index was significantly higher in ESRD group. Conclusions The results demonstrated that a significant difference was present in terms of aortic blood pressures between patients with ESRD and controls. In addition, the elastic properties of ascending aorta were decreased in patients with ESRD.

Abstract
PURPOSE Mindin was associated with diabetic nephropathy, podocyte injury, colitis, allergic asthma, liver ischaemia and reperpusion injury and ischaemic brain injury. On the other hand, it was reported as a protective factor against obesity, cardiac hypertrophy, fibrosis and remodelling. Fragmented QRS complexes (fQRS) are markers of altered ventricular depolarisation owing to a prior myocardial scar and fibrosis. In this study, we aimed to investigate mindin levels in hypertensive patients with left ventricular hypertrophy and fQRS on electrocardiography. METHODS This observational case-control study enrolled 70 (36 female) hypertensive patients with fQRS and 38 (23 female) hypertensive control patients. All patients were evaluated by transthoracic echocardiography. Mindin levels were measured by the enzyme-linked immunosorbent assay (ELISA). Clinical, echocardiographic and laboratory data were compared between patient and control groups. RESULTS There was no significant difference between patient and control groups in terms of clinical, echocardiographic and routine laboratory parameters. The mindin levels were significantly higher in the patient group than controls (11.3 (7.21-19.31) vs 4.15 (2.86-6.34); p < .001). Multiple logistic regression analyses defined increased mindin levels as an independent predictor for the presence of fQRS (Odds ratio: 1.733; p = .034). Mindin levels >6.74 predicted the presence of fQRS with a sensitifity of 84.3% and specificity of 79.9% on receiver operating characteristic (ROC) curve analysis (The area under the curve:0.889; Confidence Interval: 0.827-0.951; p < .001). CONCLUSION Mindin expressin is upregulated in hypertensive patients with fQRS complexes. In contrary to previous studies, increased mindin levels may be associated with myocardial fibrosis.

Abstract
Background/aim: Asymmetric dimethyl arginine (ADMA) is a strong predictor of cardiovascular disease and mortality in patients under hemodialysis treatment. We aimed to investigate the relationship among volume status, endothelial dysfunction, and ADMA in hemodialysis patients. Materials and methods: A total of 120 patients with a history of hemodialysis treatment were included. ADMA and CRP were measured. Echocardiographic evaluation and carotid artery intima-media thickness (CIMT) measurements were performed. Patients were divided into two groups according to clinical evaluation, ultrafiltration rate, vena cava inferior diameter (VCI), and cardiothoracic index (CTI); the two groups were hypervolemic and normovolemic. Results: The hypervolemic group included 61 patients while the normovolemic group included 59 patients. CIMT was higher in the hypervolemic group, but this result was not statistically significant (0.95 mm versus 0.85 mm, P = 0.232). There was a statistically significant difference between the hypervolemic and normovolemic groups in terms of ADMA (P < 0.001) (0.69 ± 0.57 μmol/L and 0.41 ± 0.04 μmol/L, respectively). Positive correlations were observed between serum ADMA, VCI, CTI, CRP, CIMT, and cardiac mass (P < 0.001, P = 0.016, P < 0.001, P = 0.006, P = 0.022, respectively), and negative correlations were observed between ADMA and ejection fraction and albumin (P = 0.024, P = 0.024, respectively). In multiple linear regression analysis, ADMA was independently associated with age, systolic blood pressure, CTI, and volume status. Conclusion: ADMA may be a potential determinant of hypervolemia as well as atherosclerosis in patients under hemodialysis treatment.

Abstract
BACKGROUND/AIMS The Wnt/ß-catenin pathway plays a prominent role in hepatocellular carcinoma (HCC). The Dickkopf (DKK) proteins (DKK1-4) are known Wnt antagonists; the overexpression of DKK1 has been demonstrated in HCC, and increased DKK3 methylation in the HCC tissue is associated with worse prognosis. Thus, the aim of our study was to demonstrate the diagnostic accuracy of serum DKK1 and DKK3 in HCC in comparison with that of serum alpha-fetoprotein (AFP). MATERIALS AND METHODS We included consecutive 40 HCC patients, 54 cirrhosis patients, and 39 healthy controls. Serum DKK1 and DKK3 levels were measured by an enzyme-linked immunosorbent assay, and serum AFP levels were measured by a chemiluminescence assay. RESULTS The AFP levels differed in each group and could help differentiate between groups (p < 0.001). The DKK1 levels could help differentiate the HCC group from cirrhosis and control groups (p < 0.001), and the DKK3 levels could help differentiate HCC and cirrhosis groups from the control group (p < 0.001). Combined usage of DKK1 and AFP increased the diagnostic yield, with a sensitivity, specificity, positive predictive value, and negative predictive value of 87.5%, 92.3%, 92.1%, and 87.8%, respectively. CONCLUSION Although AFP is superior to DKK1 and DKK3 in the diagnosis of HCC, the combination of DKK1 and AFP showed a better diagnostic yield than AFP alone.

Abstract
Background & Aims: Hepatic encephalopathy (HE) is a serious neuropsychiatric sequela emerging in the advanced stages of cirrhosis. The gut microbiota plays an important role in the development of HE. The aim of the study was to analyze the dynamic interplay between microbiota and Blastocystis in cirrhotic patients with or without encephalopathy.
Methods: The study was designed as cross-sectional study. A total of 37 patients from the Ankara city, admitted to the University Hospital within a 6-month period prior to enrolment into the study were included in the study. After the regular health checks, clinical histories, clinical examinations, and Psychometric HE Score (PHES) points, patients’ MELD and CTP scores were recorded. The fecal microbiota configurations were characterized by targeting hypervariable regions V3 and V4 of the 16S rRNA gene using Illumina MiSeq System.
Results: Blastocystis spp. were detected in 21.6% (n = 8) of all cirrhotic patients. When those were analyzed by subgroups, four of them were subtype 2, three were subtype 3 and one was subtype 1. Blastocystis spp. were not found in any of the patients with HE; however, they were detected in 38.1% of the patients without HE. Also the increase in the bacterial diversity was observed along with the absence of Blastocystis. It was suggested that there was an inverse relationship between Blastocystis spp. and advanced stages of HE and the structure and composition of gut microbiota.
Conclusion: The absence of Blastocystis spp. is associated with the HE severity and dysbiosis in the gut microbiota.

Abstract
BACKGROUND/AIM The aim of this study was to investigate the efficacy of a through- the-scope sodium phosphate solution with completion colonoscopy on the same day as a salvage option for inadequate bowel preparation. MATERIALS AND METHODS All participants were instructed to eat a low residual diet for 3 days before the scheduled colonoscopy and a clear liquid diet 18 h before the colonoscopy. The patients were asked to take split doses of an oral sennoside solution at 1800 and 2200 in the evening before the colonoscopy. In cases of inadequate bowel preparation detected during routine colonoscopy, a sodium phosphate solution was administered through the scope on the day of the colonoscopy procedure. The degree of bowel cleansing was assessed by the Boston Bowel Preparation Scale (BPS: 0-9). RESULTS Almost excellent bowel cleansing was obtained with a statistically significant difference between the degree of bowel cleansing before and after the application of the sodium phosphate (Boston BPS: 5.48 ± 1.01 vs. 8.88 ± 0.33 respectively, P < 0.001). CONCLUSION Through-the-scope sodium phosphate with completion colonoscopy on the same day was shown to be an efficacious and acceptable method for inadequate bowel preparation.

Abstract
This paper examines the relationship between health expenditure and economic growth using panel data consisting low and high-income countries. Using dynamic panel data methodology, we analyze twenty five high-income and nineteen low-income economies for the periods of 1995-2012 and 1997-2009, respectively. We find reciprocal relationship between health expenditure and economic growth in the short run and one-way causality from economic growth to public health expenditure in the long-run. In high-income countries, there is a two-way causality for both private and public health expenditures in the short-run, while in the long-run there is a one-way causality between economic growth and private health expenditures. The crucial finding of this study is that private health expenditures have negative influence on economic growth while public health expenditures have both negative and statistically significant effect.

Abstract
BACKGROUND/AIMS Dyssynergic defecation is a common health problem affecting the quality of life of patients adversely. We aimed to evaluate the impact of biofeedback therapy on the quality of life of constipated patients due to dyssynergic defecation. MATERIALS AND METHODS Constipated patients due to dyssynergic defecation were enrolled to the study. Patients having secondary causes of constipation and who didn't fulfill the eligible criteria were excluded. All the patients underwent three to ten sessions each of which was thirty minutes biofeedback therapy under the supervision of a trained nurse. After one month the patients were assessed for the control. The impact of biofeedback therapy on the quality of life of patients having dyssynergic defecation was assessed using the validated Medical Outcomes Study Short Form-36 (SF-36) questionnaire before and one month after therapy. RESULTS Thirty-two patients (20 female 62.5%, 12 male 37.5% and mean age 48 (18-72) underwent three to ten sessions biofeedback therapy. Post-therapy improvements of subscores of SF-36 consists of eight domains were all statistically significant when we compared with the pre-therapy values. CONCLUSION This study showed not only the effectiveness of biofeedback as a therapy modality for constipation but also its impact on the improvement of QOL of constipated patients due to dyssynergic defecation. Patients with chronic constipation not improved by dietary fiber and laxatives should be referred to specialized centers that have facilities for further anorectal physiological assessments.

Abstract
Depression and mood disorders occur commonly following emergent cardiac surgery. Selective serotonin reuptake inhibitors are commonly used antidepressants. We report the development of severe hyponatremia leading to adverse clinical effects due to escitalopram and thiazide diuretic use concomitantly in a patient with depression after emergency coronary artery bypass grafting.

Abstract
BACKGROUND/AIMS Our aim is to assess the relationship between interleukin 1β (IL-1 β), (-511,-31 alleles), interleukin 1RN (IL-RN), Helicobacter pylori (HP) status and gastroesophageal reflux disease (GERD) diagnosed by pH monitoring in the Turkish population. MATERIALS AND METHODS A Total of 100 consecutive patients with GERD were enrolled in the study. Genotypes of IL-1β (-511,-31), IL-1RN gene polymorphisms and HP status of the patients were analyzed. RESULTS While thirty-two patients were diagnosed as esophagitis with varying severity the remaining patients had no esophagitis. Seventy six participants were positive for HP and the remaining patients were negative. The difference between erosive and non-erosive groups was statistically significant when we compared IL-1β (-511) but no difference regarding IL-1β (-31) and IL-1RN variations. We also analyzed T/T, C/T and C/C alleles and the difference was significant statistically in T/T allele between patients with and without erosive GERD 1 (3.1%) vs. 12 (17.9%), respectively with a p value<0.05. But C/C, C/T alleles of (-511), (-31) and IL-1RN polymorphisms were not statistically significant between the groups. CONCLUSION IL-1β genetic polymorphisms may take part in the pathophysiology of gastroesophageal reflux disease.

Abstract
BACKGROUND/AIMS An association between ineffective esophageal motility and gastroesophageal reflux disease is already known, but there are also some conflicting data. We evaluated the association between ineffective esophageal motility and gastroesophageal reflux disease in patients who underwent ambulatory pH monitoring for the evaluation of reflux symptoms at Gazi University, Gastroenterology Clinic. MATERIALS AND METHODS A total of 239 patients who underwent endoscopy, esophageal manometry and ambulatory 24-h pH monitoring due to reflux symptoms were enrolled. Of them, we selected patients who had normal esophageal motility and ineffective esophageal motility. The endoscopy and ambulatory pH monitoring findings were compared between the two groups. RESULTS Of the 239 patients who presented with reflux symptoms, pathologic acid reflux or endoscopic esophagitis was found in 114 (48%). Ineffective esophageal motility was found in 18 (16%) in the pathologic reflux group and in 4 (3%) in the functional reflux group (p=0.01). Ambulatory pH, manometric and demographic findings were compared in ineffective esophageal motility and normal motility groups. Lower esophageal sphincter (LES) pressures were lower in the ineffective esophageal motility group (19.7 versus 16.2; p=0.01), and total reflux times in both supine and upright position were higher (10.3 versus 4.9; p=0.01) inthe ineffective esophageal motility group. Ineffective esophageal motility patients were older and more obese than normal motility group patients. CONCLUSIONS This study points to a clear association between ineffective esophageal motility and gastroesophageal reflux disease as defined by ambulatory pH monitoring.
