Effects of passive exposure to tobacco, socioeconomic status and a family history of essential hypertension on lipid profiles in children
(International Heart Journal Association, 1996) Işcan A.; Uyanik B.S.; Vurgun N.; Ece A.; Yiǧitoǧlu M.R.
There is abundant evidence that the atherosclerotic process begins in childhood. Dyslipidemia is a major risk factor for atherosclerosis in adults and children. In the present study, we measured serum lipoprotein concentrations in 194 healthy children aged between 4 to 14 years. Children were grouped according to the socioeconomic status of the families, family history of essential hypertension and passive tobacco exposure. The values of total cholesterol, low density lipoprotein cholesterol and the ratio of total cholesterol/high density lipoprotein cholesterol in the low socioeconomic group were found to be significantly higher than the values obtained for the middle-high socioeconomic group. The values of total cholesterol, low density lipoprotein cholesterol, the ratio of total cholesterol/high density lipoprotein cholesterol and low density lipoprotein cholesterol/high density lipoprotein cholesterol in the passive smoker group were found to be significantly higher than those of the nonsmoker group. But, the socioeconomic level in the passive smoker group was found to be significantly lower than that of the nonsmoker group, and therefore, the impact of passive smoking on the serum lipids in children was related to socioeconomic status. A significant difference in terms of blood lipid fractions between the groups with and that without a family history of essential hypertension was not found. These results suggest that passive smoking and lower socioeconomic status are important risk factors for cardiovascular heart disease, while a positive family history of essential hypertension is not an important risk factor.
Renal functions of enuretic and nonenuretic children: Hypernatriuria and kaliuresis as causes of nocturnal enuresis
(Elsevier B.V., 1997) Vurgun N.; Gumus B.H.; Ece A.; Ari Z.; Tarhan S.; Yeter M.
Objective: The aim of this study was to investigate the pathophysiologic cause(s) of primary nocturnal enuresis. Therefore, electrolyte concentrations of urine specimens were evaluated in the morning, and alterations compared between enuretics and nonenuretics. Methods and Patients: First morning urine specimens of 27 enuretics and 21 nonenuretic subjects fed the same diet were collected, and urinary electrolytes were measured. The urinary Ca/Cr ratio, tubular reabsorption of phosphorus (TRP) and fractional sodium (FE Na%) and potassium excretions (FE K%) were determined for patients and controls. Results: There was no significant difference in the Ca/Cr ratio and TRP between patients and controls, but enuretic patients had significantly higher FE Na% and FE K% values than controls (p < 0.001). There were significant positive correlations between FE Na% and (r = 0.81, p < 0.001) FE K% and the frequency of bedwetting, respectively, among enuretic patients (r = 0.54, p < 0.001). Conclusion: Since Na and K excretion of enuretic patients was higher than in nonenuretics, it can be concluded that there may be a benign hereditary and/or postural renal tubular handling disorder of Na and K in enuretic children.
Should children with infection be tested for lipid, lipoprotein and apolipoprotein?
(1998) IŞĆn A.; YiŞitoŞl̈ R.; OnaǦ A.; Vurgun N.; Ari Z.; Ertan P.; Şengil A.Z.
The lipid profile is known to alter in patients with infection, but there has not been a study of the apolipoprotein levels in serum of otherwise healthy children during infection. Lipids, lipoproteins, apolipoproteins A-l and B and lipoprotein (a) were evaluated prospectively in 31 consecutive children, aged4–15 years, who were admitted to the hospital with bacterial pharyngitis. The degree of dyslipidemia associated with bacterial pharyngitis was assessed using each child as his/her own control and by comparison with 79 healthy children who had not had an infection during the past 3 months. Serum total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, apolipoprotein A-l and apolipoprotein B levels were significantly decreased during the symptomatic phase of the disease, whereas the serum triglyceride level was slightly elevated. Serum lipoprotein (a) concentration did not change significantly. In conclusion, it is suggested that serum lipids, lipoproteins and apolipoproteins should not be assessed during infection because of the possible transient changes of these parameters during infection or inflammation. © 2017 Wiley.

Hypernatriuria and kaliuresis in enuretic children and the diurnal variation
(Elsevier Inc., 1998) Vurgun N.; Yicrossed d Signitocrossed d Signlu M.R.; Ýpcan A.; Ari Z.; Tarhan S.; Balkan C.
Purpose: We investigate the underlying pathophysiological cause of primary nocturnal enuresis by comparing electrolyte alterations in urine samples of enuretics during the daytime and nighttime compared with those of nonenuretic subjects. Materials and Methods: Urine output, urine specific gravity and urinary electrolytes in 15 enuretic and 12 nonenuretic children were measured. We collected daytime serum and urine samples of children fed a similar diet between 7 a.m. and 7 p.m., and nighttime between samples 7 p.m. and 7 a.m. Urinary calcium/creatinine ratio, tubular reabsorption of phosphorus and excretions of fractional sodium and potassium were calculated. Results: There was no significant difference between the calcium/creatinine ratio ratios. There was a significant increase in fractional sodium and fractional potassium values in enuretics compared to nonenuretics during the day and at night. Daytime and nighttime fractional sodium and fractional potassium values in enuretics were similar. In contrast to nonenuretics, enuretic patients had no diurnal variation of fractional sodium. There was significant positive correlation between bedwetting status, and fractional sodium and fractional potassium. Conclusions: Since sodium and potassium excretions were higher in enuretic patients than nonenuretic children, and no significant diurnal variation in urinary excretion of these ions there might be a difference in the mechanism of reabsorption of sodium and potassium between enuretic and nonenuretic children.

Low levels of high density lipoprotein cholesterol in Turkish children: An important risk factor
(1998) Işcan A.; Yiǧitoǧlu M.R.; Vurgun N.; Uyanik B.S.; Akyildiz M.
In Turkish adults, the incidence of coronary artery disease (CAD) has been found to be high. However, no detailed lipid, or lipoprotein data of children are available from Turkey. The present study was designed to define the borderline lipid and lipoprotein levels of sera in 397 healthy children (aged 5-14 years; 206 boys and 191 girls). Mean levels of total cholesterol (TC), triglyceride (TG), high- and low-density lipoprotein cholesterol (HDL- C and LDL-C, respectively) were found to be 150, 79, 46.7, and 87.6 mg/dL, respectively, for boys, and 152, 77.5, 46.3 and 90.5 mg/dL, respectively, for girls. Lipids and lipoproteins did not show any significant correlation with age and body mass index (BMI), except for TG in boys in whom TG levels were positively correlated with age and BMI. There were no significant differences in lipid and lipoprotein levels between boys and girls. As in the Turkish adult population, serum HDL-C levels of Turkish children were profoundly low on international comparison. Twenty-three (53%) of 43 children with low HDL- C level (≤ 35 mg/dL) had abnormal ratios of TC/HDL-C (≤ 5) and/or LDL- C/HDL-C (≤ 4.5), whereas only 13 (3.7%) of the remaining 354 children with a HDL-C level less than 35 mg/dL had abnormal ratios of TC/HDL-C (≤ 5) and/or LDL-C/HDL-C (≤ 4.5). The low levels of HDL-C in Turkish children may be associated with the high incidence of CAD in the Turkish adult population.

Prevalence of nocturnal enuresis and accompanying factors in children aged 7-11 years in Turkey
(Scandinavian University Press, 1999) Gümüş B.; Vurgun N.; Lekili M.; Işcan A.; Müezzinoǧlu T.; Büyüksu C.
There has been limited epidemiological research about nocturnal enuresis in Turkey. The objectives of this study were to ascertain the prevalence of nocturnal enuresis and the epidemiological factors associated with this in Turkish children aged 7-11 y, living in Manisa. Included in the study were 2000 children from various primary schools in Manisa. Parents were asked to fill out our specially designed questionnaire. In all, questionnaires for 1703 children were completed and returned to the department (871F, 51.1%; 832M, 48.9%). The prevalence of nocturnal enuresis for females was 10.6%, for males it was 16.9% and the overall prevalence was 13.7%. The prevalence of nocturnal enuresis decreased with age. Enuresis nocturna was found to be more common in children with a family history of bedwetting (76.5%). Deep sleeping, poor toilet habits and low educational level of the family were associated with enuresis. Consanguineous marriage did not influence the incidence of enuresis nocturna. There was no difference between enuretics and non-enuretics with reference to breastfeeding, being firstborn or being right- or left-handed. In our opinion, enuresis is an important problem for both families and children in Turkey for which specific guidelines should be developed. Various methods have been tried in the treatment of enuresis because of its multi-factorial aetiology. Child, family and physician co- operating together achieve the best help to both child and family.
Serum lipid and lipoprotein profile in children with iron deficiency anemia
(1999) Aydin E.; Yiǧitoǧlu M.R.; Vurgun N.; Güven H.; Işcan A.
Background: A close association has been found between serum lipoprotein abnormalities and the risk of atherosclerosis. In adults, high stored body iron, high serum iron concentrations and low iron binding capacity were found to be risk factors for coronary heart disease. Iron-deficient diets have caused contradictory lipid changes in rats. This report investigates the relationships between iron deficiency, macronutrient intake and the serum lipid and lipoprotein profiles in children with iron deficiency anemia (IDA). Methods and Results: Fifty-six children with IDA, aged 3.0±1.3 years and 60 healthy age- and sex-matched controls were evaluated. The mean total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C), lipoprotein (a) levels and LDL-C/high density lipoprotein cholesterol (HDL-C) and TC/HDL- C ratios of the IDA group were significantly lower than those of controls. While there were no differences in triglycerides and apolipoprotein B (apoB) values between patients and controls, apolipoprotein A-1 (apoA-1) and HDL-C levels were higher in the IDA group. Dietary energy, carbohydrates, total fat and protein intakes of the IDA group were lower than those of controls. After oral iron supplementation, the lipoprotein profile of patients with IDA became similar to controls. In the multivariate analysis, while energy was taken as a covariate, them was no difference in the lipid profile of patients and controls. Conclusions: Patients with IDA are also deficient in macronutrients. The low atherogenic serum lipid profile of IDA is not a direct result of iron deficiency itself, but related to decreased energy and protein intakes.
The influence of physical activity on attention in Turkish children
(2012) Adsiz E.; Dorak F.; Ozsaker M.; Vurgun N.
This study aims to determine the influence of regular physical activity on attention among 4th and 5 th graders. A total of 60 4 th and 5 th graders aged between 9-11 participated in the study. This is an experimental study which employs a pretestposttest control group design. The experimental and control groups consisted of 30 children each, who did and did not engage in sports activities respectively. The data were collected using personal information form and Bourdon Attention Test, and analyzed using Gretl software package with multiple regression analysis. The results show that physically active children had significantly higher attention levels compared to sedentary children (p<0.05). In conclusion, engaging in physical activities regularly and under the supervision of a trainer positively affects attention development in 4 th and 5 th graders.
Self esteem, physical activity and sedentary lifestyle associated with physical performance among turkısh elemantary school children
(Drunpp-Sarajevo, 2012) Özşaker M.; Dorak F.; Vurgun N.
This research was conducted in order to determine the relationship between Physical performance and self esteem among the children aged between 12-14 in terms of age, gender and participation in sports and exercises. The research was conducted with 865 students from Izmir city center who participated voluntarily (407 females, 458 males; 270 active and 595 not active sports participants). Some anthropometric and Physical tests were administered to determine the students' Physical performance. The motor performance tests used were as follows: right-left hand graspstrength and standing long jump for muscle strength, 30 second shuttle test for muscle endurance, sit-reach test for flexibility, 30 meter run test for speed, and 1 mile (1609 meters) run test for cardiovascularendurance. To determine self esteem level, the short school form of the Coopersmith Self Esteem Inventory (1967) was used. The characteristics of Physical performance and self esteem were investigated among the groups (in terms of age, gender and status of sports participation) using variance analysis at 3x2x2 level and Bonferronitest. The anthropometric measurements, physical performance and self esteem scores of the female students and male students who participated in physical activity were higher than those of the female students and male students who did not participate in sports. Statistically significant relationships were found between self esteem of the children aged between 12-14 who actively participated in physical activity and their strength, speed and cardiovascular endurance.
A study on the hopelessness of Turkish physical education and sports school students; [Istraživanje bespomoćnosti studenata tjelesnog odgoja i studenata u sportskim školama]
(FACTEACHEREDUCATION, 2014) Ozsaker M.; Vurgun N.
This study aims to evaluate and compare university students' hopelessness levels for specific variables. The sample included 535 university students at the School of Physical Education and Sports (SPES) of the Adnan Menderes University. The 20- item Beck Hopelessness Scale, developed by Beck et al. (1974), was used in the study. Seber et al. (1993), Durak and Palabi{dotless}yi{dotless}koǧlu (1994) created a Turkish adaptation of the scale. Based on the data, descriptive frequencies and percentage tables were obtained. The Mann Whitney U and Kruskal-Wallis tests, nonparametric correlation and linear regression analyses were implemented using the SPSS 16.0 statistical software for the hopelessness scores. There was an insignificant correlation between students' hopelessness levels in different departments and playing sports, while students' hopelessness scores in the training department were higher than the scores of students in other departments. The low income students' hopelessness levels were higher, but there was a significant correlation between low income and middle/high income.
Effects of regular aerobic exercise on physical characteristics, body image satisfaction and self-efficacy of middle-aged women
(University of Stellenbosch, 2015) Vurgun N.
This study examined the effects of regular aerobic exercise on physical variables, body image satisfaction and self-efficacy levels of sedentary women. An exercise group and a control group consisted of 25 and 20 middle-aged women respectively. The exercise group participated in a 14-week aerobic training programme, whereas the control group did not participate in any special kind of physical activity. In addition to administering the Body Image Satisfaction Questionnaire and the Self-efficacy Scale, anthropometric variables were assessed before the commencement of the study and again immediately afterwards. The data were analysed by a one-way ANCOVA. The main results revealed significant decreases in body mass, body fat, waist-to-hip ratio, as well as significant improvements in body image satisfaction and self-efficacy scores, with large effect sizes after the intervention for the exercise group. Regular aerobic exercise had a positive effect on body image satisfaction and self-efficacy of middle-aged women. This could possibly be due to improvements in their physical characteristics that resulted from the exercise programme. © 2015 University of Stellenbosch. All rights reserved.
Flow experience and performance: A study of elite Turkish handball players
(Editura Universitatea din Pitesti, 2016) Vurgun N.; Ferudun Dorak R.; Ozsaker M.; Uludağ S.
The aim of this study was to determine the flow states of elite handball players and to examine its effects in terms of several variables. 34 (19 female- 15 male) athletes aged 27.22± 5.44 competing in Turkish Handball Super League participated in the study and as a result of a total of 17 matches (men 10, women 7), 142 participations were included into evaluation. At the end of the matches, the athletes were given Personal Information Forms together with the form on their perceptions of the difficulty levels of the competition and the Dispositional Flow State Scale-2, which was developed by Jackson and Eklund (2004) and adapted into Turkish by Aşçı et al. (2007). As a result of the study, it was found that elite female handball players had higher flow experiences than elite male handball players. Flow experiences of handball players aged 30 and over were found to be significant at a higher level than those of handball players aged 30 and under; it was also concluded that the relationship between perception of difficulty and flow state, duration of game, gender and age are effective determiners. © JPES.
Effects of 10 weeks of imagery and concentration training on visual focus and free-throw performance in basketball players.
(Editura Universitatii din Pitesti, 2021) Uludağ S.; Dorak F.; Vurgun N.; Yüzbaşioğlu Y.; Ateş E.
Problem Statement: Free throw shooting is one of the unique techniques applied in the game of basketball. It is a technique that needs special attention to develop due to the fact that it is a unique shot. As much as physiological characteristics prepare the body for the shot, it is important to acknowledge that psychological state of the player affects it, too. Free throw shots can be vital for winning games. Purpose: The purpose of the study was to examine the effects of 10 weeks of imagery and concentration training on visual focus and free-throw performance in basketball players. The participants consisted of 29 basketball players (11 female, 18 male) from different teams in Izmir that compete at the youth level (age 15.62 ±,09). Approach: The participants were divided equally into homogenous groups pre-test and were evaluated based on their success rate. While the study was not done with the control group, the implementation was done with the imagery and concentration group for 10 weeks, three times a week for 15 minutes a day. Concentration studies were done with yantra. In the imagery studies, the athlete was asked to watch the recording of the best shot they made, and to recreate it. Before the participants recreate it, they were advised to read the imagery script and then use the information provided to mentally recreate this material from their desired viewpoint and from an alternative perspective. At the end of 10 weeks, the athletes were tested again. The study investigated whether the mental training affected visual focus or performance or not.Results: The results of this study revealed that there was a significant difference between the pre-test and post-testing protocols of the concentration group, while the control and imagery groups revealed no significant difference (p<0.028). Conclusions: Present findings show that concentration trainings with yantra have an improving effect on visual focus. In order to better understand the effect of imagery and concentration training on performance, different tests can be done. Also, before investigating the effects of imagery trainings on performance, imagery skills of the athletes can be measured. © 2021, Editura Universitatii din Pitesti. All rights reserved.
