The effect of levothyroxine replacement therapy on lipid profile and oxidative stress parameters in patients with subclinical hypothyroid.

The purpose of this present study is to investigate the levels of oxidative stress parameters in patients with subclinical hypothyroidism (SH) and the effects of levothyroxine (LT4) replacement therapy on these parameters and lipid profile. At the beginning of the study blood samples were collected from the patients in order to analyse oxidative stress parameters, lipid profile and biochemical markers. After replacement therapy with LT4, in the third month, same tests were performed again. At the baseline superoxide dismutase (SOD) levels were found to be higher in SH patients, compared to the euthyroid group. After LT4 therapy, statistically significant decreases in SOD and catalase levels and increase in HDL-C levels were noticed. LT4 treatment was found to have positive effects on oxidative stress indicators and HDL-C levels.

Projection of new thresholds for hypertension to outpatient clinic patients and impact of risk factors: a cross-sectional study.

BACKGROUND: The 2017 American College of Cardiology (ACC)/American Heart Association (AHA) guidelines on hypertension management recommend new stage 1 hypertension thresholds (130-139/80-89 mmHg) for starting antihypertensive treatment. OBJECTIVE: To analyze the impact of the 2017 ACC/AHA guidelines on patients' diagnoses within daily practice, in comparison with management using the 2018 European hypertension guidelines, regarding the new thresholds. DESIGN AND SETTING: Cross-sectional study conducted in a hypertension outpatient clinic at a tertiary-level public hospital. METHODS: The diagnosis of hypertension was defined separately using each guideline. The participants were patients who were attending the hypertension clinic, who were evaluated using the thresholds of two guidelines, based on cardiovascular risk factors, including age, gender, smoking status, diabetes mellitus, dyslipidemia, obesity, osteoporosis, chronic renal failure and family history of hypertension. RESULTS: After adapting the guidelines to the blood pressure values of our sample, 74.5% (n = 277) of the patients were diagnosed as hypertensive according to the blood pressure classification of the European Society of Cardiology (ESC) guidelines published in 2018, while 91.1% (n = 339) of the patients were hypertensive according to the new 2017 ACC/AHA guidelines. Multivariate regression analysis revealed that the significant demographic and cardiovascular risk factors associated with hypertension, based on the 2018 European Society of Hypertension (ESH)/ESC guidelines, were age (odds ratio, OR: 1.027; 95% confidence interval, CI: 1.001-1.054; P = 0.042), obesity (OR: 4.534; 95% CI: 1.830-11.237; P = 0.001) and family history of hypertension (OR: 2.199; 95% CI: 1.252-3.862; P = 0.006). CONCLUSIONS: The factors associated with the definition of hypertension may vary through changing the threshold values.

Angiostatin levels in diabetes mellitus patients receiving insulin treatment: associations with laboratory findings, comorbidities, and medications

Background/aim: The clinical effect of angiostatin in diabetes mellitus (DM) patients receiving insulin is a meaningful gap in the literature. In this study, we aimed to show the levels and the clinical significance of angiostatin in DM patients receiving insulin. Materials and methods: This is a case-control study. Serum angiostatin levels were determined by ELISA. A total of 83 people consisting of healthy subjects (n = 36) and patients with a diagnosis of DM receiving insulin therapy (n = 47) were included in this study. Results: The mean angiostatin levels of the DM group were significantly higher than those of the control group (86.0 ± 68.1 ng/mL and 58.0 ± 22.4 ng/mL, respectively; P = 0.011). Significantly lower angiostatin levels were determined in the DM patients receiving metformin with respect to those not receiving metformin (97.2 ± 74.4 ng/mL and 49.3 ± 7.0 ng/mL, respectively; P = 0.021). Significantly higher levels of angiostatin were observed among the DM patients using a beta-blocker (BB) than the DM patients not using a BB (115.5 ± 78.71 ng/mL and 73.44 ± 60.08 ng/mL, respectively; p = 0.029). Conclusion: This is the first study evaluating and demonstrating the serum angiostatin levels in DM patients receiving insulin. Further studies are required to understand the effect of angiostatin in diabetics and the effect of medications on angiogenesis in these patients.

Evaluation of the effects of different treatment modalities on angiogenesis in heart failure patients with reduced/mid-range ejection fraction via VEGF and sVEGFR-1.

OBJECTIVES: To investigate the clinical significance of VEGF, sVEGFR-1 in heart failure reduced ejection fraction (HFrEF) and heart failure mid-range ejection fraction (HFmrEF) patients. Methods: A total of 104 people consisting of HFrEF and HFmrEF patients (n=54) and healthy (n=50) subjects were included in this comparative cross-sectional study. The study took place in Gulhane Training and Research Hospital, Ankara, Turkey, between  2011 and 2013. Serum VEGF, sVEGFR-1, plasma pro-BNP analysis and transthoracic echocardiography were performed.  Results: The average sVEGFR-1 level of the HFrEF and HFmrEF patients was significantly higher than the control group (0.185±0.122; 0.141±0.120; p=0.013). The average sVEGFR-1 level of the HFrEF and HFmrEF patients using beta-blocker was significantly higher than the HFrEF and HFmrEF patients not using it (p=0.015). There was a significant and positive correlation between sVEGFR-1 and N-terminal pro-brain natriuretic peptide (pro-BNP)  levels in the group with HF (r=0.211, p=0.044). Conclusion: It increases awareness about the role of sVEGFR-1 in HFrEF anf HFmrEF patients and the need for further studies. Beta-blocker may have a negative effect on angiogenesis in HFrEF and HFmrEF via increasing sVEGFR-1 levels. Additionally, Pro-BNP may contribute to inhibiting angiogenesis by increasing sVEGFR-1 levels and sVEGFR-1 may be an important biomarker in HFrEF and HFmrEF.

Vascular endothelial growth factor and soluble vascular endothelial growth factor receptor-1 in patients with end-stage renal disease. Associations with laboratory findings, comorbidities, and medications.

OBJECTIVES: To show the levels of vascular endothelial growth factor (VEGF), soluble vascular endothelial growth factor receptor-1 (sVEGFR-1) in patients with end-stage renal disease (ESRD) and to show the associations with clinical findings such as demographic features, laboratory findings, comorbidities, and medications. METHODS: A total of 73 people, consisting of patients with ESRD (n=38) and healthy subjects (n=35) in Gulhane Education and Research Hospital, Ankara, Turkey, were included in this cross-sectional study between the years 2011 and 2013. Blood samples were obtained and plasma VEGF, sVEGFR-1 analyzes were performed. Results: The VEGF level of ESRD group was not significantly higher (0.280±0.264) than the control group (0.321±0.210) (p=0.475). The sVEGFR-1 level of ESRD group was significantly higher (0.217±0.135) than the control group (0.068±0.047) (p less than 0.001). The correlation between VEGF and sVEGFR-1 was significant and negative (r=-0.246, p=0.036). Average VEGF level of ESRD patients using recombinant human erythropoietin (rhEPO) was significantly higher (0.567±0.28) than the ESRD patients not using rhEPO (0.246±0.24) (p=0.025). CONCLUSION: Our study is the first showing the significance of sVEGFR-1 in ESRD patients, and associations with comorbidities, medications. Especially our finding of rhEPO and VEGF may illuminate a reasonable positive effect of rhEPO on angiogenesis. Soluble vascular endothelial growth factor receptor-1 and VEGF may be important markers in the pathophysiology of ESRD.

Morvan syndrome: a rare cause of syndrome of inappropriate antidiuretic hormone secretion.

The syndrome of inappropriate antidiuretic hormone secretion (SIADH) accounts for an important part of hyponatremia cases. The causes of SIADH can be detected almost always. As a rare disorder, Morvan Syndrome can be defined by the sum of peripheral nerve hyperexcitability, autonomic instability and neuropsychiatric features. Antibodies to voltage-gated potassium channels (Anti - VGKC-Ab) including contactin associated protein-like 2 antibodies (CASPR2-Ab) and leucine-rich glioma inactivated protein 1 antibodies (LGI1-Ab) were previously known for the potential association with this condition. We present a Morvan Syndrome in a patient who presented with various neuropsychiatric symptoms and SIADH.

Evaluation of self-administered versus interviewer-administered completion of Edinburgh Claudication Questionnaire.

BACKGROUND: The aim of this study was to determine the impacts of different administration modes on sensitivity and specificity of Edinburgh Claudication Questionnaire (ECQ) in estimation of Ankle Brachial Index (ABI) detecting lower extremity arterial disease (LEAD). METHODS: Eligible respondents aged fifty years or older underwent first a self-administered (SA-) ECQ, and then an interviewer-administered (IA-) ECQ. Interviewing included additional guidance on symptoms relevant to claudication. ABI was measured by hand-held Doppler. RESULTS: A total of 177 respondents (age: 64.67±9.19, male/female: 80/97) were enrolled. Questions 1, 2, 3, and 5 (collectively defines claudication) were responded significantly different on SA-ECQ and IA-ECQ modes. Markings of pain on the figure of ECQ also changed significantly when the procedure was guided. Of the respondents, none on SA-ECQ and 13.6% on IA-ECQ with positive claudication had a low ABI. Subjects with higher formal education level did similar to the whole group in both modes. Sensitivity and specificity of IA-ECQ was calculated as 25% and 88.5%, respectively, for ABI detected LEAD. CONCLUSIONS: Respondents' perceptions of pain, discomfort, exertion or body regions described on ECQ may subject to errors without guidance. ECQ seems reliable in evaluating claudication only when specifically interviewed by an observer.

Coping Attitudes of Cancer Patients and Their Caregivers and Quality of Life of Caregivers.

BACKGROUNDS AND AIM: Cancer process is a traumatic period for both patients and their caregivers. Caregivers of the patients use various coping methods to minimize the effects of anxiety-creating negativities in their daily lives. The present study aimed to examine the coping attitudes adopted by the patients and caregivers and the effects of this process upon the quality of life (QoL) of caregivers. METHODS: The cross-sectional study was conducted on three groups of (i) 74 patients consisting of those hospitalized in the department of medical oncology in tertiary care hospital or coming to the health center for chemotherapy treatment as cancer outpatients and (ii) 46 caregivers of patients; and control group 46 healthy individuals. Face-to-face interviews were conducted with the study patients to administer a short sociodemographic questionnaire, coping attitudes assessment scale (COPE), and Short Form-36 (SF-36) QoL scale. RESULTS: Statistically significant differences were recorded among patients, caregivers, and control groups in terms of "problem-focused coping" and "dysfunctional coping" the COPE scale (P = 0.001, P = 0.017). According to scores taken from the SF-36 scale, there was a statistically significant difference between caregivers and control groups in all parameters (P < 0.05). CONCLUSION: Patients and caregivers should be encouraged to use the coping methods related to the source of the problem rather than the dysfunctional coping methods. Evaluation of the QoL indicators of not only the patients but also their caregivers enables to formulate a more integrated approach and detection of the expectations of the caregivers.

Individual variations in ankle brachial index measurement among Turkish adults.

PURPOSE: Variability of ankle brachial index (ABI) measured by the same observer in the same individual on three different occasions was examined. BASIC METHODS: A single morning ABI was initially determined (measurement 1) with handheld Doppler device. One to four weeks apart, another morning (measurement 2) and afternoon (measurement 3) ABI was measured on the same day. PRINCIPAL FINDINGS: A total of 161 adults were enrolled. Mean ABI was similar among the three measurements. ABI differed more than ≥0.15 in 15 individuals between measurement 1 and 3, in 10 subjects between measurement 1 and 2, and in 12 individuals between measurement 2 and 3. Intra-group correlation coefficients of reproducibility of ABI were 0.808 for single measurements (coefficient of the values lacking association with each other), and 0.927 for average measurements (coefficient of the values that were associated with each other). CONCLUSIONS: Although reproducibility of ABI values was found satisfactory, up to 12% of participants displayed more than 0.15 alternations between measurements, either on the same day or more than a week apart.

Tonsillectomy, adenoidectomy and adenotonsillectomy rates in school-aged children: Relative contributions of socio-demographic and clinical features.

OBJECTIVES: The present study sought to investigate the frequencies of tonsillectomy, adenoidectomy and both adenotonsillectomy (T&A) among 6-12 years old children. In addition, we tried to find out the predictors associated with these previous upper respiratory tract (URT) surgeries. METHODS: This cross-sectional study consisted of 1900 children educated in 3 different elementary schools in Ankara, Turkey. Data about demographics and health conditions were obtained from survey questionnaires completed by parents. RESULTS: Of the 1900 children, 15 children (0.8%) previously underwent tonsillectomy, 43 children (2.3%) had adenoidectomy and 80 children (4.2%) had T&A surgical histories. Multiple logistic regression analysis revealed that older students compared to younger ones [odds ratio (OR) = 1.15, p = 0.011], and those who had parent-reported apnea compared to subjects without apnea were more likely to have URT surgery histories [OR = 2.34, p = 0.001]. Those children with surgery histories were more likely to have fathers with a higher educational level [medium level: OR = 2.07, p = 0.012; high level: OR = 2.79, p = 0.001 vs. low level) and the subjects had greater BMI percentiles [overweight: OR = 1.71, p = 0.036; obesity: OR = 2.32, p = 0.003 vs. healthy weight]. Children who had 1-2 URT infections per year [OR = 0.47, p = 0.019] had less probability of URT surgery histories, whereas those children with AOM ≥ 3 times per year [OR = 2.52, p = 0.003] had more probability of URT surgery history. CONCLUSIONS: We conclude that a reasonable explanation for higher rates of URT surgery among children with a high level of paternal education may originate from their awareness about URT associated diseases and possibly due to the ease of access to health care services.

Association of renal function, estimated by four equations, with coronary artery disease.

OBJECTIVE: Individuals with impaired renal function are at increased risk of coronary artery disease (CAD). CAD is also associated with an increased likelihood of having chronic kidney disease (CKD). In the present study, we sought to determine the association between impaired renal function with CAD presence and CAD severity based on four different estimated glomerular filtration rate (eGFR) equations. METHODS: We estimated GFR values using four equations: modification of diet in renal disease (MDRD), Cockcroft-Gault (C-G), chronic kidney disease epidemiology (CKD-Epi), and Mayo Quadratic. Three hundred and fifty-six CAD patients were classified by the number of stenotic coronary arteries occluded >50%, while the CAD severity was categorized based on the number of involved coronary arteries determined to be healthy, single- and multi-vessel disease. RESULTS: The mean values of eGFR calculated by CKD-Epi, MDRD, Mayo, and C-G equations were 77.44, 71.34, 96.33, and 89.49 mL/min/1.73 m(2) respectively. Based on these equations, the prevalence of eGFR <60 mL/min/1.73 m(2) among the patients with significant CAD was 41.5, 45.2, 50, and 42.9%, respectively. eGFR values calculated by four formulas were significantly higher in healthy subjects than those with single-vessel disease (p < 0.001, p = 0.004, p = 0.003, and p = 0.028, respectively). Prediction of CAD severity was statistically significant for men but not women. After controlling for the confounding effects of other covariates, three of the equations were independently related to significant CAD: CKD-Epi (p = 0.004, ß = 0.969), MDRD (p = 0.003, ß = 0.965), and C-G (p = 0.021, ß = 0.978). CONCLUSION: The present study established that accurate eGFR equations commonly used still accurate to determine the association of the impaired renal function with CAD presence and extent.
