RESUMEN
OBJECTIVES: Systemic sclerosis (SSc) is a complex immune-mediated connective tissue disease, involving skin manifestations, vascular features, and organ-based complications that may affect functional capacity and physical activity. Functional capacity and physical activity are associated with arterial stiffness; however, this relationship has not been evaluated in patients with SSc. Therefore, the objective of this study was to investigate the association of functional capacity and physical activity with arterial stiffness in patients with SSc. METHODS: Sixty-five patients with SSc were enrolled in this cross-sectional study. Arterial stiffness was evaluated with carotid-femoral pulse wave velocity (cf-PWV). Functional capacity and physical activity were assessed with a six-min walk test (6MWT) and International Physical Activity Questionnaire-Short Form (IPAQ-SF), respectively. RESULTS: All participants were women, and the mean age was 54.91 ± 11.18 years. 6MWT distance and IPAQ-SF were inversely associated with cf-PWV in crude analysis (p < 0.05). The relationship between 6MWT distance and cf-PWV was maintained in the fully adjusted model (ß = - 0.007, 95% CI, - 0.013 to 0.000). Similarly, the association between IPAQ-SF and cf-PWV remained significant in the fully adjusted model (ß = - 0.001, 95% CI, - 0.002 to - 0.001). CONCLUSION: The present study indicates that functional capacity and self-reported physical activity are independently associated with arterial stiffness in patients with SSc. Exercise interventions targeted to increase functional capacity and physical activity may help to regulate arterial stiffness in patients with SSc. Key Points ⢠Arterial stiffness is an independent predictor of cardiovascular risk. ⢠SSc patients exhibit decreased exercise capacity and functional capacity. ⢠The association of functional capacity and physical activity with arterial stiffness in patients with SSc is unknown. ⢠Functional capacity and self-reported physical activity are independently associated with arterial stiffness in patients with SSc.

BACKGROUND: The impact of a single-session Pilates exercise on cardiorespiratory fitness and metabolic parameters is still uncertain. AIMS: The aim of this study was to examine the cardiorespiratory changes during a single-session Pilates exercise and compare cardiorespiratory fitness-related parameters with walking at different speeds on a treadmill, at low (3.2 kph) and moderate intensities (4.8 kph). METHODS: Cardiorespiratory responses were measured with a cardiopulmonary exercise test device in 31 healthy young adults at rest, during a single Pilates session, walking at 3.2 kph and walking at 4.8 kph. The study design employed a cross-over design. Participants were randomly assigned to two experimental groups: a Pilates training session following treadmill walking or treadmill walking following a Pilates training session. RESULTS: Mean MET, oxygen and energy consumption during Pilates were similar to walking at 3.2 kph (p > 0.05), but significantly lower than walking at 4.8 kph (p < 0.05). The mean heart rate during Pilates was higher than walking at 3.2 kph (p < 0.05), but similar to walking at 4.8 kph (p > 0.05). Significantly higher carbohydrate metabolism was used during Pilates compared to walking (p < 0.05). CONCLUSION: The cardiopulmonary responses to a single Pilates session are similar to walking at a speed of 3.2 kph but lower than walking at 4.8 kph. These results indicate that while Pilates may not generate sufficient cardiopulmonary changes to enhance cardiorespiratory fitness as a moderate-intensity exercise in healthy young adults, it may still offer other benefits such as improvements in flexibility, core strength, and posture.

OBJECTIVE: One of the most frequently discussed physical parameters in juvenile idiopathic arthritis (JIA) is physical activity level. There is limited evidence about determinants of physical activity level in JIA. In this study, we aimed to investigate the determinants of physical activity level in children and adolescents with JIA. MATERIALS AND METHODS: Thirty-two JIA patients and 18 age- and sex-matched healthy individuals were included in the study. The age range was 8-18 years. Sociodemographic and clinical data of the participants were recorded. In both groups, anthropometry, fatigue, pain, knee extension muscle strength, gait variables, functional exercise capacity assessed by six-minute walk test (6MWT), and arterial stiffness were evaluated. Physical activity level was assessed by an accelerometer. RESULTS: The disease activity level of the patients was low. Pain and fatigue scores were significantly higher in the JIA group compared to healthy controls (pâ¯< 0.05). Walking speed, physical activity level, time spent in low-intensity physical activity, time spent in moderate-to-vigorous-intensity physical activity, and 6MWT distance were significantly lower than in healthy controls (pâ¯< 0.05). Quadriceps muscle strength and arterial stiffness assessment results were similar in both groups (pâ¯> 0.05). In the JIA group, there was a positive correlation between physical activity and age, height, fat-free body mass, quadriceps muscle strength, and 6MWT distance (pâ¯< 0.05). Also, there was a negative correlation between physical activity and pain, fatigue, and cadence. Physical activity level was independently associated with 6MWT distance (42.9% of the variability). CONCLUSION: In mildly affected JIA patients, gait speed, functional exercise capacity, and physical activity level are affected. Functional exercise capacity is a determinant of physical activity level in JIA.

OBJECTIVES: The aim of this study was to investigate the determinants of six-minute walk test (6MWT) distance in women with systemic sclerosis. METHODS: In this cross-sectional study, 36 women with systemic sclerosis were assessed using the Medsger Systemic Sclerosis Severity Scale (MSS), modified Rodnan Skin Score (mRSS), Health Assessment Questionnaire (HAQ), University of California Scleroderma Clinical Study Consortium Gastrointestinal Tract Scale, quadriceps strength measurement, Milliken Activities of Daily Living Scale (MAS), and International Physical Activity Questionnaire. The 6MWT was performed to assess the participants' functional capacity and examine factors affecting functional capacity. RESULTS: 6MWT distance was moderately associated with disease severity, with 14 participants walking less than 80% of the predicted distance. 6MWT distance was also significantly correlated with spirometry values and MSS, mRSS, HAQ, and MAS scores (p<0.05). In linear regression analysis, MSS and MAS scores were identified as independent predictors of 6MWD and accounted for 42.5% of variance (R2 = 0.425). CONCLUSION: Disease severity and activities of daily living are independently associated with functional capacity in women with scleroderma, with MSS and MAS scores accounting for 42.5% of variance in 6MWT distance in the linear regression model.

The study aimed to examine the effects of inspiratory muscle training (IMT) in patients with pulmonary hypertension (PH). A total of 24 patients with PH were included in the randomized controlled evaluator-blind study. IMT was performed at 40% to 60% of the maximal inspiratory pressure for 30 min/d, 7 d/wk (1 day supervised) for 8 weeks. Respiratory muscle strength, dyspnea, diaphragm thickness (DT), pulmonary functions, 24-hour ambulatory blood pressure (BP), arterial stiffness, exercise capacity, upper extremity functional exercise capacity, physical activity levels, fatigue, anxiety-depression levels, activities of daily living (ADL), and quality of life were evaluated. A total of 24 patients (treatment = 12, control = 12) completed the 8-week follow-up. There was no significant difference between the patient groups in terms of demographic and clinical characteristics (p >0.05). Considering the change between the groups in the treatment and control groups, brachial and central BP, dyspnea, respiratory muscle strength, DT in total lung capacity, knee extension muscle strength, functional exercise capacity, upper extremity functional exercise capacity, physical activity, ADL, fatigue, anxiety, and quality of life improved in favor of the IMT group (p <0.05). In conclusion, IMT has improved brachial and central BP, dyspnea, respiratory muscle strength, DT in total lung capacity, knee extension muscle strength, functional exercise capacity, upper extremity functional exercise capacity, physical activity, ADL, fatigue, anxiety, and quality of life compared with the control group. IMT is an effective method in cardiopulmonary rehabilitation for patients with PH.

BACKGROUND: Given the promising effects of inspiratory muscle training (IMT), determining the most appropriate IMT protocol will optimize the training benefits. OBJECTIVES: The objective of this study was to determine the effects of high intensity interval-based inspiratory muscle training (H-IMT) on cardiovascular, pulmonary, physical, and psychosocial functions in patients with heart failure and reduced ejection fraction (HFrEF). METHODS: Thirty-four patients with HFrEF were randomly assigned to the H-IMT or control group for 3 days/week, 8 weeks training period. The H-IMT group performed IMT at least 70% of the maximal inspiratory pressure, whereas the control group performed unloaded IMT. Each session occurred 7 sets with a total of 21 min consisting of 2-min training and 1-min interval. Heart rate variability (HRV), arterial stiffness, respiratory muscle strength and endurance, diaphragm thickness, quadriceps strength, functional capacity, frailty, dyspnea, fatigue, disease-specific health-related quality of life (HRQoL), and generic HRQoL were evaluated at baseline and after 8 weeks training period by blinded assessors. RESULTS: Statistically significant between-group differences were observed in the time domain parameters of HRV, arterial stiffness, inspiratory and quadriceps muscle strength, respiratory muscle endurance, diaphragm thickness, functional capacity, frailty, dyspnea, fatigue, and disease-specific HRQoL in favor of the H-IMT group (p<0.05). CONCLUSIONS: H-IMT is an effective protocol for improving cardiac autonomic function, arterial stiffness, inspiratory and quadriceps muscle strength, respiratory muscle endurance, diaphragm thickness, functional capacity, frailty, dyspnea, fatigue, and disease-specific quality of life in patients with HFrEF. CLINICAL TRIAL REGISTRATION: NCT04839211.

BACKGROUND: The 6-minute step test (6MST) has begun to be used as a simple and effective alternative for assessing functional exercise capacity. There is no study using 6MSTs to evaluate the exercise capacities of patients with type 2 diabetes mellitus (DM) with and without diabetic peripheral neuropathy (DPN). OBJECTIVE: To compare the cardiorespiratory responses of the 6-minute walk test (MWT) and the 6MST exercise tests and to analyze the usability of the 6MST in Type 2 DM patients with and without neuropathy. METHODS: 32 non-neuropathic Type 2 DM, 32 neuropathic Type 2 DM patients, and 30 healthy volunteers were included in this cross-sectional study. Functional exercise capacity was evaluated with the 6MWT and the 6MST. The 30-second sit-stand test (30s STS) was used to evaluate general lower extremity muscle strength and function. RESULTS: There was a significant difference in the results of 6MWT (m), 6MST (number of steps), and 30s STS of the three groups (p<0.05). The 6MST results of patients with neuropathic Type 2 DM were significantly lower than those of non-neuropathic diabetics and those who were healthy (number of steps; 114.07±25.57 vs. 133.48±33.57 vs. 160.35±28.52, respectively) (p=0.001). The change in cardiorespiratory response in systolic blood pressure, heart rate, perceived dyspnea, and leg fatigue severity was significantly higher at 6MST than 6MWT in the three groups (p<0.05). 6MST was correlated with 6MWT (r=0.679, p=0.001), and 30s STS (r=0.589, p=0.001) in patients with Type 2 DM. CONCLUSIONS: Cardiorespiratory responses increased more in 6MST compared to 6MWT. In patients with Type 2DM, 6MWT and 6MST were moderately correlated with each other. 6MST is an effective and safe assessment method that may better reveal the differences in functional exercise capacity between neuropathic and non-neuropathic individuals in clinics.

PURPOSE: Previous publications showed the effectiveness of exercise in adults with cancer receiving palliative care, but evidence for palliative care research on exercise is lacking. The purpose is to examine the effects of an exercise intervention on exercise capacity, physical function, and patient-reported outcome measures in adults with cancer receiving palliative care. METHODS: We searched databases including EMBASE, PubMed, and Web of Science from inception until 2021. We used the Cochrane criteria to assess the risk of bias within studies. Using RevMan, mean difference (MD) and 95% confidence intervals or standardized mean difference (SMD) and 95% confidence intervals were calculated. RESULTS: A total of 14 studies and 1034 adults with cancer receiving palliative care are included in this systematic review and meta-analysis. Half of the studies were deemed to have high risk of bias. All of the interventions used aerobic and/or resistance exercises. The results indicated that exercise interventions significantly improved exercise capacity (mean difference: 46.89; 95% confidence interval: 4.51 to 89.26; Z = 2.17; P = 0.03), pain (standardized mean difference: - 0.29; 95% confidence interval: - 0.54 to - 0.03; Z = 2.18; P = 0.03), fatigue (standardized mean difference: - 0.48; 95% confidence interval: - 0.83 to - 0.12; Z = 2.66; P = 0.008), and quality of life (standardized mean difference: 0.23; 95% confidence interval: 0.02 to 0.43; Z = 2.12; P = 0.03). CONCLUSION: Exercise training, with aerobic exercise, resistance exercise, or combined aerobic and resistance exercise, helps to maintain or improve exercise capacity, pain, fatigue, and quality of life in adults with cancer receiving palliative care.

BACKGROUND: The 6minute walk test (6MWT) is a commonly used to evaluate exercise capacity in patients with systemic sclerosis (SSc), but there was no study using the incremental shuttle walking test (ISWT) for assessing exercise capacity and comparing the patient's cardiorespiratory responses to these tests. The aim was to investigate the usability and determinants of the ISWT in patients with SSc and compare the physiological responses after the ISWT and 6MWT. METHODS: A total of thirty four female patients with SSc were included. Dyspnea during daily activities and knee extensor muscle strength was assessed, skin fibrosis and disease severity were recorded, and 6MWT and ISWT were carried out for the exercise capacity measurement. Pulmonary function test results were recorded from the individuals' medical records for SSc with interstitial lung disease (SSc-ILD) patients. RESULTS: The ISWT distance was significantly correlated with the 6MWT distance (pâ¯< 0.001). The 6MWT was correlated with age, modified Rodnan skin score, Medsger severity score, modified British Medical Research Council Questionnaire (mMRC) score, and knee extensor muscle strength (pâ¯< 0.05). The 6MWT was correlated with the forced expiratory volume in the first second (FEV1) (lt) and forced vital capacity (FVC) (lt) in patients with SSc-ILD (pâ¯< 0.05). The ISWT distance was correlated with age, modified Rodnan skin score, mMRC score, and knee extensor muscle strength (pâ¯< 0.05). Age, mMRC, and knee extensor muscle strength explained 33.8% of the variance in 6MWT distance, while age, mMRC, and knee extensor muscle strength explained 51.7% of the variance in the ISWT distance. CONCLUSION: Because of the higher cardiopulmonary responses, and having a more standardized procedure, the ISWT may be preferable for investigating symptom-limited exercise capacity in patients with SSc. Age, dyspnea, and knee extensor muscle strength were the determinants of exercise capacity in patients with SSc.
RESUMEN
OBJECTIVE: Given the prognostic significance of gait speed, there is insufficient evidence about possible functional determinants of gait speed in patients with heart failure with reduced ejection fraction (HFrEF). Therefore, the objective of this study was to investigate the functional determinants of gait speed in patients with HFrEF. METHODS: Fifty-nine patients with HFrEF participated in this cross-sectional study. Demographic and clinical characteristics were recorded. The gait speed was determined with a 4-meter walking test. Dyspnea perception was assessed with the modified medical research council (mMRC) scale. Functional capacity was evaluated with a 6-minute walk test (6MWT). The five times sit-to-stand (5-STS) test and the Berg Balance Scale (BBS) were used to measure functional mobility and balance. Physical activity was evaluated with the International Physical Activity Questionnaire (IPAQ) Short-Form. RESULTS: Gait speed was correlated with age (r=-0.368, p=0.004), NYHA functional class (r=-0.438, p=0.001), mMRC score (r=-0.422, p=0.001), 6MWT (r=0.650, p<0.001), 5STS (r=-0.506, p<0.001), BBS (r=0.586, p<0.001), IPAQ (r=0.305, p=0.019) and IPAQ-Sitting time (r=-0.327, p=0.011). On multiple linear regression analysis, the 6MWT distance and BBS were independent determinants of the usual gait speed in patients with HFrEF, accounting for 44.4% of the variance. CONCLUSION: This study indicates that functional capacity and balance are independent functional determinants of gait speed in patients with HFrEF.

Introduction and objective: Asthma, is the most common chronic inflammatory disease in childhood period. It can affect the daily life to an advanced level and may become vital. The purpose of this study is to compare physical fitness and anaerobic capacity in asthmatic children (AC) and non-asthmatic children (NC). Materials and methods: A total of 47 children participated in the study; 25 individuals with mild to moderate asthma and 22 healthy children were assessed. The assessed variables consist pulmonary function and peripheral muscle strength (PMS). Additionally, physical fitness was evaluated by using fitnessgram test battery, which includes body composition, modified shuttle walk test (MSWT), curl-up test, push-up test, and sit and reach test variables. Anaerobic capacity was measured with wingate anaerobic capacity test (WAnT) and counter-movement jump (CMJ) using a tri-axial accelerometer. Results: FEV1/FVC ratio (p = 0.01), MSWT (p = 0.001), push-up test (p = 0.01), and WAnT peak power (p = 0.05) were measured significantly to be found reduced in AC compared with that of NC. Between the two groups, PMS, curl-up test, sit and reach test, and CMJ were not significantly different (p = 0.05). High to moderate positive correlation was found among WAnT, CMJ parameters and FEV1, fat-free body mass (FFM), dominant handgrip, and quadriceps strengths (p = 0.05). Conclusions: Physical fitness level and anaerobic capacity were lower in AC compared with that of NC. Physical fitness parameters and anaerobic exercise capacity should be evaluated on the physiotherapy and rehabilitation program in AC (AU)

Background/aim: The aim of the study was to carry out the cultural adaptation and translation of the ICU mobility scale (IMS) into Turkish and research the psychometric properties. Materials and methods: This study was based on methodological design. The IMS was translated from English to the Turkish through a regularised translation process. Two physiotherapists assessed patients independently in the coronary intensive care unit. The measures such as construct validity, intra and interrater reliability, and internal consistency of the IMS Turkish version were assessed. Results: A total of 70 intensive care patients were included in the study. The intrarater and interrater reliability of the IMS was excellent. The weighted Kappa value was 0.92 (0.870.96) for the intrarater reliability, and 0.87 (0.800.93) for the interrater reliability. There were significant correlations between the IMS and functional status score for the intensive care unit (r = 0.83), Perme intensive care unit mobility score (r = 0.84), Katz activities of daily living (r = 0.73), handgrip strength (r = 0.62), knee extension strength (r = 0.46), and age (r = 0.44). Conclusion: This study suggests that the IMS Turkish version is a reliable and valid scale for assessing functional status and mobility level in ICU patients.

Background/aim: Dyspnea is the subjective feeling of breathing discomfort, which is a significant problem for patients with heart and respiratory disease and also an important determinant of exercise tolerance, quality of life, and mortality in various diseases. Most of the scales are not enough to investigate the multidimensional effects of dyspnea; therefore, the Multidimensional Dyspnea Profile (MDP) was developed and validated in many languages. This study aimed to translate and culturally adapt the MDP into Turkish and investigate the psychometric properties of this adapted version in outpatients with respiratory disease. Materials and methods: The MDP was translated and culturally adapted into Turkish following published guidelines. A total of 170 outpatients with respiratory disease were included to assess psychometric properties. The factorial structure was investigated using a principal component analysis. Two situations were used in this study evaluating dyspnea in activity-related and resting conditions. We formulated 17 hypotheses for each MDP domain (in total 68) to assess construct validity, and correlations were investigated between the MDP and measures of body mass index, pulmonary function test, other dyspnea assessments, anxiety, depression, and health-related quality of life. To investigate the test-retest reliability, the MDP was administered again after 1-h and 1 week Results: Internal consistency of the MDP was excellent (Cronbach's alpha coefficients ranged from 0.89 to 0.93). The exploratory factor analysis revealed 2 components explaining a 70% and 76% variance. Overall, 64 of the 68 predetermined hypotheses (94%) were confirmed to test construct validity. The MDP showed excellent test-retest reliability for a 1-hperiod (intraclass correlation coefficient values ranged from 0.98 to 0.99). However, test-retest reliability decreased moderate-to-high after 1 week (0.530.80). Conclusion: The MDP was successfully translated and culturally adapted into Turkish and this version showed good psychometric properties including the factorial structure, internal consistency, test-retest reliability, and construct validity to assess multidimensional aspects of dyspnea.

BACKGROUND: Cystic Fibrosis (CF), affecting functional exercise capacity generally measured by submaximal exercise test such as 6min walk test, is a progressive, autosomal recessive and metabolic disorder. Three-axis accelerometers, which are used during gait, are an easy way to assess gait parameters in patients and healthy individuals. Gait parameters were significantly associated with clinical outcomes of COPD. However, the association between gait parameters and clinical outcomes in children with CF is unclear. RESEARCH QUESTION: Do clinical outcomes in CF have an important role in determining gait parameters?. METHODS: Twenty-one CF and 21 healthy subjects participated in this case-control study. Body composition was evaluated using Tanita-BC 418. Respiratory and knee extension muscle strengths were assessed. Functional exercise capacity was evaluated using the 6-min walk test (6MWT). Spatiotemporal gait parameters were evaluated using a validated wireless inertial sensing device (G-Sensor, BTS Bioengineering S.p.A., Italy) during the 6MWT and 7-meter gait test. RESULTS: MIP, the distance of 6MWT, and stride length were significantly lower in the CF group compare to healthy children (p<0.05). Gait speed and functional exercise capacity, cadence and functional exercise capacity, quadriceps muscle strength, FEV1, fat-free mass were found to be correlated in CF patients (p<0.05). SIGNIFICANCE: The aerobic capacity and gait parameters were affected in CF patients with mild disease severity in our study. Clinical outcomes were associated with gait parameters in CF patients. This is the first study to use the 3-axis accelerometer to evaluate functional exercise capacity and gait parameters of CF and healthy children. A three-axis accelerometer can be used to assess functional exercise capacity and gait parameters in CF patients at the clinics.

BACKGROUND: Timed up and go (TUG) and sit to stand (STS) tests that required less space and easier to be performed in respiratory and cardiac diseases for assessing functionality. Aim was to test the reliability of TUG and 30-second STS (30STS) tests and determine the validity of TUG and 30STS tests in patients with Pulmonary Hypertension (PH). METHODS: Thirty-eight patients with diagnosed PH were included. We collected TUG, 30STS, quadriceps muscle strength, physical activity level, and 6MWT. Intra-class correlation coefficient (ICC) was used to determine test-retest reliability and correlations with quadriceps muscle strength, physical activity level and 6MWT for validity of the TUG and 30STS tests. RESULTS: The TUG and 30STS tests were associated with age, functional class, muscle strength, physical activity and functional exercise capacity in patients with PAH (p < 0.05). 6MWT was associated with age, functional class, muscle strength, physical activity and functional exercise capacity (p < 0.05). ICC (95%) for TUG test and 30STS were 0.96 (0.93-0.98) and 0.95 (0.90-0.97), respectively. CONCLUSIONS: The TUG and 30STS tests were reliable and valid tests for measuring physical performance in PH. This study supports using the TUG and 30STS tests as practical assessment tools in patients with PH.

Purpose: To translate and cross-culturally adapt the Functional Status Score for the Intensive Care Unit instrument to Turkish and investigate its psychometric properties.Methods: An expert committee supervised forward and backward translation. Thirteen participants reviewed the pre-final version of Turkish Functional Status Score for the Intensive Care Unit instrument providing minor revisions to improve its readability. Two physiotherapists assessed patients (N = 50) from a coronary intensive care unit using the Turkish Functional Status Score for the Intensive Care Unit instrument.Results: Internal consistency was excellent (Cronbach's α = 0.949). Inter-rater reliability and intra-rater reliability were excellent for each of five functional tasks and total scores (intra-class correlation coefficient = 0.955-0.996). The Turkish Functional Status Score for the Intensive Care Unit score had moderate to high correlations with other functional measures as follows: Perme Intensive Care Unit Mobility Score (Spearman's r = 0.92), Katz Activities of Daily Living (r = 0.80), handgrip strength (r = 0.76-0.77), and knee extension strength (r = 0.70-0.71).Conclusion: The Functional Status Score for the Intensive Care Unit instrument was translated and culturally adapted to Turkish and demonstrated strong psychometric properties, including internal consistency, intra-rater and inter-rater reliability, construct validity, and floor and ceiling effects.Implications for rehabilitationRehabilitation professionals strive to assess and document patient status using validated and reliable outcome measures as part of good clinical practice.Longitudinal evaluation of physical function in the intensive care units is important.The Functional Status Score for the Intensive Care Unit is a validated and reliable physical functioning measurement instrument suitable for the intensive care units.The Functional Status Score for the Intensive Care Unit was translated and culturally adapted to Turkish, and demonstrated strong psychometric properties, including internal consistency, intra-rater reliability, inter-rater reliability, construct validity, and floor and ceiling effects.

OBJECTIVE: Our goal was to determine if whole blood viscosity (WBV) can be used to predict the risk of pulmonary arterial hypertension (PAH) in patients with systemic sclerosis (SSc). METHODS: Patients with SSc were analyzed. Out of 107 patients, 26 patients, found to have confirmed diagnosis of PAH, were classified as those with (n = 26, PAH group) and without PAH (n = 81, non-PAH group). We calculated estimated WBV at both high (HSR) and low shear rates (LSR) from hematocrit and total serum protein levels. RESULTS: Total protein levels were significantly higher and the anti-centromere antibody (ACA) was more frequent in the PAH group. Furthermore, anti-topoisomerase antibody (anti-scl-70) was significantly less frequent in the PAH group. The WBV values were significantly higher at HSR (16.68 ± 0.38 vs. 16.24 ± 0.58; p < 0.001) and at LSR (51.81 ± 7.21 vs. 42.97 ± 11.76; p < 0.001) in PAH group. The multivariate analysis revealed that the WBV at both shear rates independently designated the presence of PAH in SSc patients. The ROC curve showed that the sensitivity and specificity of LSR and HSR were 92.3% and 61.7% (AUC 0.759, p < 0.001), and 88.5% and 65.4% (AUC 0.770, p < 0.001) with a cutoff value of 43.56 and 16.32 for WBV, respectively. CONCLUSION: Higher WBV levels in SSc patients were an independent indicator for PAH development in this cohort. WBV-LSR and WBV-HSR values might help exclude the PAH possibility in patients diagnosed with SSc and remain as an independently associated biomarker for follow-up of these patients for future risk of PAH development. Findings remain to be confirmed by other cohorts.Key Points⢠The most important cause of morbidity and mortality in systemic sclerosis patients is considered to be pulmonary arterial hypertension.⢠When the symptoms of PAH are not recognized earlier in the course of the SSc, the prognosis might be worse.⢠Higher whole blood viscosity levels in scleroderma patients with PAH was an independent indicator for PAH development.

Background/aim: The 6-minute walk test (6MWT) is the most commonly used and well-established test to measure functional exercise capacity in research and clinical settings. Country-specific reference values are important to interpret the results of 6MWT. However, no reference values have been reported for healthy Turkish children aged between 6 and 12 years old. The aim of this study was to determine normal reference values for the 6MWT test of healthy Turkish children aged between 6 and 12 years old. Materials and methods: Two hundred and sixty-two healthy children aged between 6 and 12 years old were included in this cross-sectional study. Measures included height, weight, body mass index (BMI), leg length, and 6MWT distance (6MWD). Results: The mean 6MWD was 572.58 (SD = 117.72) m. There were significant correlations between 6MWD and age (r = 0.764, P < 0.001), height (r = 0.742, P < 0.001), weight (r = 0.605, P < 0.001), BMI (r = 0.234, P < 0.001), and lower extremity length (r = 0.708, P < 0.001). In the stepwise multiple linear regression model, age and height explained about 60% of the variability of the 6MWT distance for the total sample. Conclusion: Reference values and prediction equation for the 6MWT in healthy Turkish children aged 612 years old have been reported for the first time in this study. Researchers and clinicians can use them to interpret the effectiveness of a treatment and/or to compare the results of disabled children with healthy ones.

BACKGROUND: Activities of daily living (ADL) are important for an independent life. As COPD progresses, the ability to complete ADL is usually reduced. Knowing the possible factors that influence the ability to perform ADL may allow better targeting of appropriate rehabilitation programs to increase the independence levels and/or to prevent further decreases in patients with COPD. Therefore, the aim of this study was to investigate ADL performance as measured by the London Chest Activity of Daily Living scale, which is a commonly used measure in patients with COPD. METHODS: This cross-sectional study included 44 clinically stable subjects who were not taking antibiotics and had not made any changes in their medications for at least three weeks with a COPD diagnosis based on Global Initiative for Chronic Obstructive Lung Disease. Demographic characteristics, pulmonary function, ADL measured by the London Chest Activity of Daily Living scale, functional exercise capacity via the 6-min walk distance, disease-related symptoms measured by the COPD Assessment Test, and peripheral and respiratory muscle strength were evaluated. A multiple linear regression (stepwise) analysis was used to determine the variables that have the greatest influence on ADL (ie, the London Chest Activity of Daily Living scale score). RESULTS: The London Chest Activity of Daily Living scale score had moderate correlations with the COPD Assessment Test score (r = 0.31, P = .041), maximum expiratory pressure value (r = -0.37, P = .01), 6-min walk distance (r = -0.48, P = .001), knee extensor muscle strength (r = -0.47, P = .001), handgrip strength (r = -0.44, P = .003). The 6-min walk distance, COPD Assessment Test score and maximal expiratory pressure values were significant and independent determinants of the London Chest Activity of Daily Living scale, with 40.1% of the variance in subjects with COPD. CONCLUSIONS: Functional exercise capacity, disease-related symptoms, and expiratory muscle strength have the greatest influence on ADL in the subjects with COPD. The level of independence to perform ADL can be increased by improving functional exercise capacity, reducing symptoms, and increasing expiratory muscle strength in subjects with COPD.

BACKGROUND: Many studies have reported that there are several differences between genders which may result in altered neuromuscular control. Although the existing evidence suggests that low back pain (LBP) affects the ability to control posture, there is little evidence the gender differences in postural control in people with nonspecific chronic LBP. RESEARCH QUESTION: Are there any gender differences in postural control and correlations between postural control, pain, disability, and fear of movement in people with nonspecific chronic LBP? METHODS: Static and dynamic postural control were evaluated using a computerized postural control assessment tool including assessments for limits of stability (LOS), unilateral stance, and modified clinical test of sensory interaction on balance. Pain intensity and fear of movement were assessed using a visual analogue scale and the Tampa Scale of Kinesiophobia, respectively. RESULTS: This cross-sectional study included 51 people (25 females and 26 males) with nonspecific chronic LBP. Mean reaction time in the LOS test was significantly less in male participants compared with females when adjusted for pain intensity and disability level, F(1,45)â¯=â¯4.596, pâ¯=â¯.037, ηp2â¯=â¯0.093. There was no significant difference in the remaining LOS variables as well as unilateral stance, and modified clinical test of sensory interaction on balance variables between the genders (pâ¯>â¯.05). Many correlations were observed between the LOS variables, pain intensity, and Tampa Scale of Kinesiophobia score in female participants (pâ¯<â¯.05). The Tampa Scale of Kinesiophobia score was also correlated with the movement velocity and endpoint excursion in the LOS test in the male participants (pâ¯<â¯.05). SIGNIFICANCE: This study suggests that there is no difference in most of the static and dynamic postural control variables between females and males; however, higher fear of movement, and pain intensity during activity are more associated with impaired dynamic balance in females with nonspecific chronic LBP.
