Abstract
OBJECTIVE Cardiac resynchronization therapy (CRT) is used in patients with heart failure (HF), an important problem in cardiology practice, with reduced left ventricular systolic dysfunctions and left ventricular dyssynchrony to improve morbidity and mortality. Thyroid diseases have undeniable effects on cardiac functions. So, we aimed to evaluate the effect of subclinical hypothyroidism on CRT response in HF patients in this study. PATIENTS AND METHODS After the exclusion, 386 consecutive patients who received first-time CRT-defibrillator (CRT-D) or CRT-pacemaker (CRT-P) were retrospectively included. Known overt hypothyroidism or hyperthyroidism patients were excluded. The response of CRT was defined as a relative increase (≥15%) or absolute increase (≥10%) in left ventricular ejection fraction (LVEF) from implantation to one-year after follow-up. RESULTS Diabetes mellitus, atrial fibrillation and coronary artery disease ratios were similar between responder vs. non-responder groups. Thyroid stimulating hormone (TSH) levels were higher (p <0.005) in non-responder group. Responder group had higher baseline LVEF (p <0.001), and follow-up LVEF (p <0.001) and longer baseline QRS interval (p =0.004), but similar post-implant QRS interval duration (p >0.005) with non-responder group. Baseline QRS interval (p =0.002), baseline LVEF (p <0.001) and the presence of subclinical hypothyroidism (SCH) (p =0.001) were independent predictors of CRT response. Adding SCH as a risk factor to our baseline risk modelling has an independent prognostic impact to predict non-responder patients (p =0.01). CONCLUSIONS Presence of the SCH may be an important predictor of non-response in patients undergoing CRT. Evaluating the risk factors associated with non-response to CRT may be logical in identifying patients who obtain maximum benefit from CRT treatment.

Abstract
PURPOSE To date, many genes have been associated with congenital hypothyroidism (CH). Our aim was to identify the mutational spectrum of 23 causative genes in Turkish patients with permanent CH, including thyroid dysgenesis (TD) and dyshormonogenesis (TDH) cases. METHODS A total of 134 patients with permanent CH (130 primary, 4 central) were included. To identify the genetic etiology, we screened 23 candidate genes associated with CH by next-generation sequencing. For confirmation and to detect the status of the specific familial variant in relatives, Sanger sequencing was also performed. RESULTS Possible pathogenic variants were found in 5.2% of patients with TD and in 64.0% of the patients with normal-sized thyroid or goiter. In all patients, variants were most frequently found in TSHR, followed by TPO and TG. The same homozygous TSHB variant (c.162 + 5G > A) was identified in four patients with central CH. In addition, we detected novel variants in the TSHR, TG, SLC26A7, FOXE1, and DUOX2. CONCLUSION Genetic causes were determined in the majority of CH patients with TDH, however, despite advances in genetics, we were unable to identify the genetic etiology of most CH patients with TD, suggesting the effect of unknown genes or environmental factors. The previous studies and our findings suggest that TSHR and TPO mutations is the main genetic defect of CH in the Turkish population.

Abstract
Purpose To compare the intraocular pressure (IOP) lowering effect and safety of latanoprost, travoprost given every evening, and the fixed combination dorzolamide + timolol (DTFC) given twice daily in pseudoexfoliation glaucoma (PXG). Methods This randomized, prospective, investigator-masked study has been conducted with 50 PXG patients. Patients were assigned to one of three groups: travoprost 0.004%, fixed combination of dorzolamide 2%+timolol 0.5%, or latanoprost 0.005% for 6 months. At baseline and 0.5, 1, 2, 3, 4, 5, and 6 months of therapy, IOP (8 am, 10 am, 4 pm), blood pressures, and pulse rates were measured, and ophthalmologic examination was performed. The side effects were recorded at each visit. Results Forty-two of the 50 patients initially enrolled completed this study. Withdrawn patients included one (latanoprost) for lack of efficacy, five (three travoprost, one latanoprost, one DTFC) for adverse events, and two (one latanoprost, one DTFC) for loss of follow-up. Each of the three drugs considerably reduced the IOP in PXG cases throughout the 6 months. Mean IOP reduction at 6 months was –9.3±2.9 mmHg in the travoprost group, -8.2±1.2 mmHg in the latanoprost group, and 11.5±3.3 mmHg in the DTFC group. Comparing the groups, DTFC is more effective than latanoprost and travoprost in lowering IOP (p<0.05). There was no difference between travoprost and latanoprost. The most common treatment-related adverse event was conjunctival hyperemia. Intensity of ocular hyperemia was greater in the travoprost group compared with the latanoprost and DTFC groups (p<0.05). There were no significant effects on systemic safety parameters. Conclusions The results demonstrated that DTFC is more effective in reducing IOP than latanoprost and travoprost. Latanoprost and travoprost had similar ocular hypotensive effects in patients with PXG. All three drugs were well tolerated; there were fewer ocular side effects attributable in the latanoprost group.

Abstract
BACKGROUND Recent findings suggest that there is a close relationship between chronic heart failure and uric acid. AIMS The aim of the study was to assess whether increased uric acid levels in patients with dilated cardiomyopathy might correlate with the degree of functional mitral regurgitation (MR). MATERIALS AND METHODS Sixty two consecutive patients diagnosed with dilated cardiomyopathy were included in the study. The patients were classified according to severity of functional MR into two groups: mild-moderate functional MR (ERO < 0.2 cm2) and severe functional MR. RESULTS The patients with severe functional MR had significantly higher serum uric acid levels compared to patients without severe functional MR (6.34 ± 1.61 mg/dL vs 5.43 ± 1.17 mg/dL respectively, p = 0.012). Furthermore, tenting area, an important predictor of functional MR severity, was moderately correlated with the serum uric acid levels (r = 0.351, p = 0.005). It was also shown that the serum uric acid concentrations were inversely correlated with left ventricular (LV) ejection fraction, and positively correlated with LV volumes. There was also a significant relation between the serum uric acid and left atrial volumes and also brain natriuretic peptide (BNP) levels. CONCLUSIONS In conclusion, this study demonstrates that elevated serum uric acid levels in patients with dilated cardiomyopathy are correlated with the severity of functional MR and echocardiographic volume indices.
