    Objective: Guidelines recommend measuring and addressing health-related quality of life in the management of atrial fibrillation (AF); however, a disease-specific questionnaire is lacking for the Turkish language. Our aim was to translate and adapt the Atrial Fibrillation Impact Questionnaire (AFImpact) into Turkish and to explore its psychometric properties. Methods: This cross-sectional study was conducted in two phases, including the translation and cultural adaptation of AFImpact into Turkish language and the analysis of psychometric properties of the translated questionnaire. 98 patients diagnosed with AF were evaluated using the Turkish version of AFImpact, Short Form-36 (SF-36) and Pittsburg Sleep Quality Index (PSQI). Reliability, validity, and factor structure of the Turkish version of AFImpact was explored. Results: Cronbach's alpha coefficients for vitality, emotional distress, and sleep domains of AFImpact was 0.956, 0.955, and 0.819, respectively, indicating good-to-excellent internal consistency. No significant difference was detected between the initial and retest scores, and intraclass correlation coefficients of each domain varied between 0.991 and 0.996, indicating excellent test-retest reliability. Each domain of AFImpact highly correlated with similar domains of SF-36 and PSQI, having correlation coefficients between -0.484 and -0.699. AFImpact was able to discriminate between the patients in different functional classes, confirming know-groups validity. Factor analysis revealed AFImpact had the same factorial structure as the original questionnaire. Conclusion: The Turkish version of AFImpact is a valid and reliable questionnaire for evaluating health-related quality of life in patients with AF.

    Sit-to-stand test in children with bronchiectasis: Does it measure functional exercise capacity?
    (2020-09-01T00:00:00Z) Zeren, Melih; Gürses, Hülya Nilgün; Denizoğlu Külli, Hilal; Uçgun, Hikmet; Çakır, Erkan; GÜRSES, HÜLYA NILGÜN; DENİZOĞLU KÜLLİ, HİLAL; UÇGUN, HİKMET; ÇAKIR, ERKAN
    Background Similar to six-minute walk test (6MWT), sit-to-stand test (STST) is a self-paced test which elicits sub-maximal effort; therefore, it is suggested as an alternative measurement for functional exercise capacity in various pulmonary conditions including COPD and cystic fibrosis. We aimed to investigate the association between 30-second STST (30s-STST) and 6MWT in both children with bronchiectasis (BE) and their healthy counterparts, as well as exploring cardiorespiratory burden and discriminative properties of both tests. Methods Sixty children (6 to 18-year-old) diagnosed with non-cystic fibrosis BE and 20 age-matched healthy controls were included. Both groups performed 30s-STST and 6MWT. Test results, and heart rate, SpO2 and dyspnea responses to tests were recorded. Results Univariate analysis revealed that 30s-STST was able to explain 52% of variance in 6MWT (r = 0.718, p<0.001) in BE group, whereas 20% of variance in healthy controls (r = 0.453, p = 0.045). 6MWT elicited higher changes in heart rate and dyspnea level compared to 30s-STST, indicating it was more physically demanding. Both 30s-STST (21.65±5.28 vs 26.55±3.56 repetitions) and 6MWT (538±85 vs 596±54 m) were significantly lower in BE group compared to healthy controls (p<0.01). Receiver operating characteristic (ROC) curve analysis revealed an area under the ROC curve (UAC) of 0.765 for 30s-STST and 0.693 for 6MWT in identifying the individuals with or without BE (p<0.05). Comparison between AUCs of 30s-STST and 6MWT yielded no significant difference (p = 0.466), indicating both tests had similar discriminative properties. Conclusions 30s-STST is found to be a valid alternative measurement for functional exercise capacity in children with BE.

    Cut-off values of 6-min walk test and sit-to-stand test for determining symptom burden in atrial fibrillation
    (2022-01-01T00:00:00Z) Zeren, Melih; Karci, Makbule; DEMİR, Rengin; GÜRSES, Hülya Nilgün; OKTAY, Veysel; UZUNHASAN, Işıl; YİĞİT, Zerrin; GÜRSES, HÜLYA NILGÜN
    Background Since symptomatology is a major predictor of quality of life and an endpoint for the management of atrial fbrillation (AF), practical approaches for objectively interpreting symptom burden and functional impairment are needed. Aims We aimed to provide cut-of values for two frequently used feld tests to be able to objectively interpret symptom burden in atrial fbrillation. Methods One hundred twenty-fve patients with AF were evaluated with European Heart Rhythm Association (EHRA) score, 6-min walk test (6MWT), 30 s sit-to-stand test (30 s-STST), Short-Form 36 (SF-36), International Physical Activity Questionnaire-Short Form (IPAQ-SF), and spirometry. Patients with EHRA 1 were classifed as “asymptomatic”, and those with EHRA 2–4 as “symptomatic”. Cut-of values of 6MWT and 30 s-STST for discriminating between these patients were calculated. Results The optimal cut-of value was “450 m” for 6MWT (sensitivity: 0.71; specifcity of 0.79) and “11 repetitions” for 30 s-STST (sensitivity 0.77; specifcity of 0.70). Area under ROC curve was 0.75 for both tests (p<0.001). Subgroup analysis revealed patients below cut-of values also had worse outcomes in SF-36, IPAQ-SF, and spirometry. Conclusions In patients with AF, walking < 450 m in 6MWT or performing < 11 repetitions in 30 s-STST indicates increased symptom burden, as well as impaired exercise capacity, quality of life, physical activity participation, and pulmonary function. These cut-of values may help identifying patients who may require adjustments in their routine treatment or who may beneft from additional rehabilitative approaches.

    The relationship of sit-to-stand tests with 6-minute walk test in healthy young adults
    (2018-01-01) Gurses, HÜLYA NİLGÜN; Zeren, MELİH; Kulli, Hilal Denizoglu; Durgut, ELİF; GÜRSES, HÜLYA NILGÜN; ZEREN, MELIH; DENİZOĞLU KÜLLİ, HİLAL; DURGUT, ELİF
    The aim of this study was to evaluate the timed sit-to-stand (STS) test performances of healthy young adults and to investigate the relationship of timed STS tests with 6-minute walk test (6MWT). A cross-sectional study was performed. A total of 40 healthy volunteers (mean age: 21.7 +/- 1.2 years) were evaluated with 10, 30, and 60seconds STS tests and 6MWT. Fatigue and shortness of breath were rated using Borg category-ratio scale (CR10) before and after each test. Weekly energy expenditures of volunteers were calculated using International Physical Activity Questionnaire. 30 and 60seconds STS tests were moderately (r=0.611 and r=0.647, respectively) (P.05). Borg fatigue scores after 10, 30, and 60seconds STS tests were weakly correlated with fatigue score after 6MWT (r=0.321, r=0.378, and r=0.405, respectively) (P<.05). Weekly energy expenditure (MET-min/week) was moderately correlated with 10, 30, and 60seconds STS tests and 6MWT (r=0.533, r=0.598, r=0.598, and r=0.547, respectively) (P<.001). Considering the statistically significant relationship between timed STS tests and 6MWT, any of the timed STS tests may be used for a quick and alternative measurement of physical performance and functional capacity in healthy young adults.

    Relationship of respiratory muscle strength, pulmonary function, and functional capacity with quality of life in patients with atrial fibrillation.
    (2018-01-01) DEMIR, R; Zeren, MELİH; Gurses, HÜLYA NİLGÜN; YIGIT, Z; ZEREN, MELIH; GÜRSES, HÜLYA NILGÜN
    Objective: To examine the relationship of pulmonary parameters and functional capacity with quality of life (QoL) in patients with atrial fibrillation (AF). Methods: Thirty-six patients with chronic AF were included in this cross-sectional study. QoL was assessed with the Medical Outcomes Survey 36-item Short Form (SF-36) and Minnesota Living with Heart Failure Questionnaire (MLHFQ). Respiratory muscle strength and pulmonary function were also measured. Functional capacity was assessed with the 6-min walk test (6MWT). The Borg CR10 Scale was used to determine the resting dyspnea and fatigue levels. Results: The SF-36 physical component summary score was correlated with the maximum inspiratory pressure (r ¼ 0.517), maximum expiratory pressure (r ¼ 0.391), 6MWT distance (r ¼ 0.542), resting Borg dyspnea score (r ¼ 0.692), and resting Borg fatigue score (r ¼ 0.727). The MLHFQ total score was correlated with the maximum inspiratory pressure (r ¼ 0.542), maximum expiratory pressure (r ¼ 0.384), 6MWT distance (r ¼ 0.535), resting Borg dyspnea score (r ¼ 0.641), and resting Borg fatigue score (r ¼ 0.703). The resting Borg fatigue score was the significant independent predictor of the SF-36 physical component score and the MLHFQ total score. Conclusion: Respiratory muscle strength, functional capacity measured with the 6MWT, and resting symptoms including dyspnea and fatigue may have an impact on QoL in patients with AF.

    (2020-07-01T00:00:00Z) Gürses, Hülya Nilgün; Denizoğlu Külli, Hilal; Durgut, Elif; Zeren, Melih; GÜRSES, HÜLYA NILGÜN; DENİZOĞLU KÜLLİ, HİLAL; DURGUT, ELİF
    Objective: Our study aimed to determine the sit-to-stand (STS) test performance and physical activity levels of young adults and investigate the relationship of STS tests with gender and physical activity levels. Methods: Sixty volunteers randomly performed the 5xSTS, 10sSTS, 30sSTS and 60sSTS tests. Fatigue was rated using the Borg category ratio scale. Physical activity level and weekly energy expenditure of volunteers were calculated using the International Physical Activity Questionnaire. Results: The 5xSTS, 10sSTS, 30sSTS and 60sSTS test scores were statistically different between genders (p=0.004; p=0.002; p=0.000; p=0.000, respectively). Fatigue levels after STS tests did not show any difference between genders (p=0.636; p=0.295; p=0.888; p=0.150, respectively). Weekly energy expenditures were positively correlated with STS tests except 5xSTS test (r=-0.458, p=0.000; r=0.427, p=0.001; r=0.606, p=0.000; r=0.545, p=0.000, respectively). All STS tests had significant differences between participants with moderate or high physical activity level (p=0.016; p=0.007; p=0.000; p=0.000, respectively). Conclusion: Our study shows that STS tests scores correlate to gender and physical activity levels in young adults.
