Compliance with guideline recommendations in the management of patients with hospitalized community-acquired pneumonia.

Compliance with guidelines in the empirical treatment for community-acquired pneumonia (CAP) is very important to increase treatment success and reduce mortality. This study aimed to determine compliance with guideline recommendations for CAP and define the role of the clinical pharmacist (CP). Patients diagnosed with CAP were evaluated retrospectively between January 2018 and January 2020 and prospectively between February 2020 and February 2021. Compliance with guidelines was evaluated according to the local, national (Turkish Thoracic Society), and international (American Thoracic Society and Infectious Disease Society of America, European Society of Clinical Microbiology and Infectious Diseases) guidelines. A total of 751 patients (423 in the retrospective and 328 in the prospective period) were included. It was determined that the 30-day mortality and length of stay were higher in patients who were not treated according to the guidelines. The compliance for empirical treatments was 16.3%-59.1% and 7.8%-30.1% in retrospective and prospective periods, respectively. During the prospective period, a total of 603 recommendations were made by CP, and 578 (95.9%) were accepted and implemented. In the prospective period, treatment duration was shortened, inappropriate fluoroquinolone use was decreased, the switch to oral treatment was increased, and the number of potential drug-drug interactions was decreased (p < 0.001). Compliance with guidelines is essential to be improved to reduce mortality, shorten the length of stay, determine the appropriate antimicrobial duration, and reduce the use of fluoroquinolones and broad-spectrum antibiotics unless necessary. CP intervention contributes to the rational selection of antimicrobials, limiting drug-drug interactions, avoiding toxicities, and compliance with guidelines.

Decreased plasma levels of sphingolipids and total cholesterol in adult cystic fibrosis patients.

BACKGROUND: Sphingolipid species in the lung epithelium have a critical role for continuity of membrane structure, vesicular transport, and cell survival. Sphingolipid species were reported to have a role in the inflammatory etiology of cystic fibrosis by previous work. The aim of the study was to investigate the levels of plasma sphingomyelin and ceramide in adult cystic fibrosis (CF) patients and compared with healthy controls. MATERIALS AND METHODS: Blood samples were obtained from CF patients at exacerbation (n = 15), discharge (n = 13) and stable periods (n = 11). Healthy individuals (n = 15) of similar age served as control. Levels of C16-C24 sphingomyelin and C16-C24 ceramide were measured in the plasma by LC-MS/MS. Also, cholesterol and triglyceride levels were determined in plasma samples of the patients at stable period. RESULTS: All measured sphingomyelin and ceramide levels in all periods of CF patients were significantly lower than healthy controls except C16 sphingomyelin level in the stable period. However, plasma Cer and SM levels among exacerbation, discharge, and stable periods of CF were not different. CF patients had significantly lower cholesterol levels compared to healthy individuals. We found significant correlation of cholesterol with C16 sphingomyelin. CONCLUSION: We observed lower plasma Cer and SM levels in adult CF patients at exacerbation, discharge, and stable periods compared to healthy controls. We didn't find any significant difference between patient Cer and SM levels among these three periods. Our limited number of patients might have resulted with this statistical insignificance. However, percentage of SM16 levels were increased at discharge compared to exacerbation levels, while percentage of Cer16 and Cer 20 decreased at stable compared to exacerbation. Inclusion of a larger number of CF patients in such a follow up study may better demonstrate any possible difference between exacerbation, discharge, and stable periods.

Upper Extremity Exercise Capacity and Activities of Daily Living in Individuals With Bronchiectasis Versus Healthy Controls.

OBJECTIVE: The purpose of this study was to compare the upper extremity exercise capacity and activities of daily living (ADL) in individuals with bronchiectasis and controls. METHODS: Twenty-four individuals with bronchiectasis and 24 healthy controls were assessed for upper extremity exercise capacity (6-minute pegboard and ring test [6PBRT]) and ADL (Glittre ADL test). Energy expenditure was measured using a wearable metabolic monitor during the Glittre ADL test. RESULTS: The mean [SD] 6PBRT score of individuals with bronchiectasis was significantly lower than the mean score of controls (196.50 [51.75] vs 243.00 [29.76] number of rings). The Glittre ADL test duration was significantly higher in individuals with bronchiectasis compared with controls (3.54 [1.53] vs 2.36 [0.18] minutes), despite similar energy expenditure during the Glittre ADL test between the groups (17.67 [5.28] kcal in individuals with bronchiectasis vs 18.13 [5.71] kcal in controls). The 6PBRT score and the Glittre ADL test duration were negatively correlated in individuals with bronchiectasis (r = -0.694). CONCLUSION: The individuals with bronchiectasis had reduced upper extremity exercise capacity compared with healthy controls. Energy expenditure during ADL was similar between individuals with bronchiectasis and healthy controls, despite lower ADL performance in individuals with bronchiectasis. The upper extremity exercise capacity and ADL are related in individuals with bronchiectasis. Given this relationship, inclusion of upper extremity exercise training in pulmonary rehabilitation programs should be considered. IMPACT: Considering the impairment of upper extremity exercise capacity and ADL in individuals with bronchiectasis highlights the need to tailor preventive strategies and preclude further unfavorable effects. LAY SUMMARY: Bronchiectasis may reduce exercise capacity in your arms and reduce your ability to perform daily living activities. Physical therapists can evaluate your condition and create rehabilitation programs to help manage these impairments.

Metabolomic, oxidative, and inflammatory responses to acute exercise in chronic obstructive pulmonary disease.

BACKGROUND: There is currently a need to identify metabolomic responses to acute exercise in chronic obstructive pulmonary disease (COPD). OBJECTIVE: We investigated the metabolomic, oxidative, and inflammatory responses to constant (CE) and intermittent (IE) work rate exercises in COPD. METHODS: Sixteen males with COPD performed a symptom-limited incremental cycle exercise test (ICE). Metabolomic, oxidative, and inflammatory responses to CE and IE (based on the performance of ICE) were analyzed in the plasma. RESULTS: Fructose-6-phosphate, 3-phosphoglyceric acid, l-carnitine, and acylcarnitines levels were significantly decreased, whereas alpha-ketoglutaric, malic, 2-hydroxybutyric, and 3-hydroxybutyric acids were increased, after CE and IE (p<0.05). Increases in citric, isocitric, and lactic acids, as well as decreases in pyruvic and oxalic acids, were only present with IE (p<0.05). Isoleucine was decreased after both exercises (p<0.05). We observed an increase in inosine-5'-diphosphate, uric acid, ascorbic acid, and pantothenic acid, as well as a decrease in 5-hydroxymethyluridine, threonic acid, and dehydroascorbic acid, after IE (p<0.05). Catalase, reduced glutathione, and total antioxidant status difference values for both exercises were similar (p>0.05). The change in glutathione peroxidase (GPx) with CE was more significant than that with IE (p = 0.004). The superoxide dismutase change was greater with IE than with CE (p = 0.015). There were no significant changes in inflammatory markers after exercise (p>0.05). CONCLUSION: CE and IE cause isoleucine, l-carnitine, and acylcarnitine levels to decrease, whereas ketone bodies were increased, thus indicating the energy metabolism shift from carbohydrates to amino acid utilization and lipid metabolism in COPD. Compared with CE, IE produces significant changes in more metabolomics in terms of carbohydrates, lipids, amino acids, nucleotides, and vitamins. Acute CE and IE alter circulating GPx levels in COPD.

Gait and functional balance in non-CF bronchiectasis.

BACKGROUND: The decline in ambulatory activities and negative alterations in gait characteristics may impair balance and increase fall risk in obstructive lung diseases. Few studies have evaluated balance and gait parameters in individuals with bronchiectasis. PURPOSE: This study aimed to compare the gait parameters and functional balance in individuals with non-cystic fibrosis (CF) bronchiectasis and healthy subjects. METHODS: This cross-sectional and retrospective study analyzed data from 22 individuals with non-CF bronchiectasis and 32 healthy controls recorded between July 2019 and July 2020. Functional balance was assessed using the Timed Up and Go (TUG) test. Gait parameters were evaluated using the Biodex Gait Trainer. Step cycle (s), gait speed (m/s), the number of steps per minute, and ambulation index were measured for 6 min.Results The TUG time (s) was significantly longer (p = .019, effect size = 0.66), and gait speed (m/s) (p ˂ 0.001, effect size = 2.47), step cycle (s) (p ˂ 0.001, effect size = 2.23), and ambulation index (p ˂ 0.001, effect size = 2.56) were significantly reduced in individuals with non-CF bronchiectasis compared with healthy controls. CONCLUSION: Non-CF bronchiectasis is related to unfavorable changes in gait characteristics, such as slower gait speed and the decreased average step cycle. In addition, impairment in functional balance and mobility exists in a small percentage of adults with non-CF bronchiectasis. In comprehensive pulmonary rehabilitation, balance and gait evaluations should be included to prevent falls in adults with non-CF bronchiectasis.

Increased Plasma YKL-40 Level and Chitotriosidase Activity in Cystic Fibrosis Patients.

We investigated plasma YKL-40 levels and chitotriosidase (CHIT1) activity in patients with cystic fibrosis (CF) lung disease and evaluated clinically relevant factors that may affect their levels. Plasma samples were obtained from pediatric (n = 19) and adult patients (n = 15) during exacerbation, discharge, and stable period of the disease. YKL-40 levels and chitotriosidase activity were measured by enzyme-linked immunosorbent assay and fluorometric assay, respectively. Data were compared with healthy children and adults of similar age. YKL-40 levels of pediatric and adult CF patients at all periods were significantly higher than controls (p < 0.001 and p < 0.05). CHIT1 activities of adult patients at all periods were significantly higher compared to controls (p < 0.05). On the other hand, CHIT1 activities of pediatric CF patients were similar with controls. YKL-40 levels of exacerbation period of adult CF patients were negatively correlated with forced vital capacity (FVC) (r = - 0.800, p = 0.014) and forced expiratory volume in 1 s (FEV1) (r = - 0.735, p = 0.008). YKL-40 levels in the exacerbation period of pediatric CF patients were negatively correlated with FVC (r = - 0.697, p = 0.0082) and FEV1 (r = - 0.720, p = 0.006). CHIT1 activity may be a valuable marker of chronic inflammation in adult CF patients who suffer from CF for a longer period compared to pediatric patients. Increased YKL-40 levels in both pediatric and adult patients compared to controls may point to a role in between CF pathology.

Daily living activities, exercise capacity, cognition, and balance in COPD patients with and without frailty.

BACKGROUND: Information on the interaction between frailty and chronic obstructive pulmonary disease (COPD) is limited. AIMS: This study aimed to compare activities of daily living (ADL), exercise capacity, balance, and cognition in COPD patients with and without frailty. METHODS: Twenty frail and 28 non-frail COPD patients aged 55 years and over were included. Frailty was determined according to Fried et al. Dyspnea was evaluated using the modified Medical Research Council (mMRC) dyspnea scale. Respiratory and peripheral muscle strength were measured. Functional capacity was assessed using a 6-min walk test (6MWT); ADL performance was evaluated using the Glittre ADL test. The balance was evaluated using the functional reach test (FRT). Cognitive function was assessed using the Montreal Cognitive Evaluation (MoCA) Test. Quality of life was measured using the COPD Assessment Test (CAT). RESULTS: The mMRC and CAT scores were higher in the frail patients as compared with the non-frail patients (p < 0.05). The maximal inspiratory pressure, handgrip strength, 6MWT distance, and FRT score were lower in the frail patients as compared with the non-frail patients (p < 0.05). The duration for the Glittre ADL test was longer in the frail patients than the non-frail patients (p < 0.05). There was no significant difference between MoCA scores between groups (p > 0.05). CONCLUSIONS: Frail COPD patients have increased dyspnea perception, impaired muscle strength, and functional capacity, ADL performance, balance, and quality of life. Whether pulmonary rehabilitation programs for patients with frail COPD need to be adapted with new rehabilitation strategies, including components of frailty, needs further investigation.

Environmental asbestos exposure and nonmalignant pleural findings: a retrospective evaluation of a five-year chest CT repository.

This registry-based case-control study aimed to assess the association between asbestos deposits in the birthplace and/or residence and nonmalignant pleural findings, namely pleural plaques (PPs) and pleural thickening (PT), on chest CT scans. In total, 39,472 CT scans obtained over five years in a tertiary referral hospital in Ankara, Turkey, were evaluated. Cases involving patients with PP (n = 537), PT (n = 263), PP&PT (n = 69), and controls (n = 543) from the same study base without those conditions were included. Each case group was compared to controls using unconditional logistic regression. The presence of asbestos deposits in the district of birthplace (adjusted OR = 2.13, 95% CI: 1.35-3.37) and both birthplace and residence (aOR = 4.32, 95% CI: 2.26-8.27) was significantly related to the PPs. As the importance of environmental asbestos exposure in Turkey continues, future prospective studies could contribute to developing screening strategies.

Performance of pulmonary embolism severity index in predicting long-term mortality after acute pulmonary embolism.

OBJECTIVE: In this study, we aimed to evaluate the accuracy of the original and simplified pulmonary embolism (PE) severity index (PESI) to predict all-cause mortality after 30 days of acute PE diagnosis up to five years within consecutive sub-periods. METHODS: Adult patients diagnosed with acute PE between January 1, 2003, and June 30, 2013, were retrospectively included. Data on baseline characteristics and mortality during a five-year follow-up were collected. RESULTS: The study included 414 patients (Male/Female=192/222). The median age at diagnosis was 61.5 (minimum-maximum, 18-93) years. Mortality rates were 13.3% at 30 days, 21.8% at 90 days, 32.6% at one year, and 51.0% at five years. Both stratification into risk classes according to the original PESI and low vs. high-risk classification of original and simplified PESI were significantly correlated with the 30-day, 31-90-day, 91-day-one-year, and one-five-year mortality. Significant PESI predictors for mortality were history of cancer [hazard ratio (HR): 3.31, 95% confidence interval (CI): 1.64-6.68; p=0.001] and heart failure (HR: 2.35, 95% CI: 1.04-5.32, p=0.041) at 31-90-day, history of cancer (HR: 5.45, 95% CI: 2.86-10.40, p<0.001) at 91-day-one-year, advancing age (HR: 1.04, 95% CI: 1.02-1.06, p<0.001) and history of cancer (HR: 5.53, 95% CI: 3.41-8.98, p<0.001) at one-five-year after acute PE diagnosis. CONCLUSION: All-cause long-term mortality in high-risk patients with acute PE according to original or simplified PESI significantly increased up to five years of follow-up. This survival disadvantage was mainly related to cancer and comorbidities rather than acute clinical manifestations. Future prospective studies are needed to demonstrate the effect of various comorbidities on long-term mortality in these patients.

Factors related to oxygen desaturation during flexible bronchoscopy and endobronchial ultrasound.

INTRODUCTION: Oxygen desaturation is a significant event during bronchoscopy. In this study, it was aimed to identify factors related to oxygen desaturation during flexible bronchoscopy (FB) and Endobronchial ultrasound (EBUS). MATERIALS AND METHODS: From 16 April 2019 to 14 February 2020, 196 consecutive patients (146 FB and 50 EBUS) undergoing bronchoscopy were evaluated retrospectively. The patients' oxygen saturations were monitored on admission and during the procedure by finger pulse oximetry. Desaturation was defined as saturation below 90%. Demographic characteristics, comorbidities, types of interventions, vitals before and during the procedure, amount of saturation decline, and sedative agents used were recorded. The data obtained were compared between the desaturated and non-desaturated groups in both FB and EBUS. We evaluated the risk factors for desaturation during bronchoscopic procedures. RESULT: The mean age of those who underwent FB was higher (62 [52-68] years vs. 55 [44-65] years, p= 0.05), and males were more frequent (54%, vs 19.2%, p<0.001) in the desaturated group. In FB, short lavage was more frequent in the non-desaturated group (28.8% vs. 9.5%, p<0.001). In EBUS, hypertension, diabetes mellitus and thyroid diseases were higher, and duration of procedure was longer (p= 0.02, p= 0.04, p= 0.01 and p<0.001 and p= 0.01, respectively), and SpO2 decline during procedures was higher (11% vs. 1% in FB, 18% vs. 3% in EBUS, p<0.001, each) in the desaturated group. CONCLUSIONS: This study suggested that baseline SpO2 and SpO2 decline during procedures as well as sex, hypertension, and concomitant endocrine - metabolic diseases, duration of procedure were factors associated with desaturation in patients who had undergone FB and EBUS.

Association between 6 min pegboard and ring test and arm performance in GOLD stage II-III patients.

BACKGROUND: The 6 min pegboard and ring test (6PBRT) is a valid and reproducible test of unsupported arm exercise endurance. The aim of this study was to determine the associations between the 6PBRT, activities of daily living (ADL) and hemoglobin levels in chronic obstructive pulmonary disease (COPD). METHODS: This study included 40 stable patients with COPD. All participants underwent the 6PBRT, peripheral venous blood sampling, arm ergometer test and the Glittre-ADL and ADL simulation tests for the ADLs performance. RESULTS: An average 172.51 ± 25.94 rings were moved in 6 min. The number of rings in 6PBRT was significantly positively correlated with the number of cycles in ADL simulation test (r = 0.553, p < 0.001), peak oxygen consumption in arm ergometer (r = 0.381, p = 0.024) and serum hemoglobin level (r = 0.411, p = 0.011). CONCLUSION: The number of rings moved in the 6PBRT is associated with ADL simulation test performance that reflects upper extremity ADLs. Therefore, the 6PBRT can be used for estimating limitation in upper extremity ADLs as a simple and quick evaluation in patients with GOLD stage II-III COPD.

Sustainable inspiratory pressure and incremental threshold loading for respiratory muscle endurance in chronic obstructive pulmonary disease: A pilot study.

INTRODUCTION: A prolonged mismatch between the demand for respiratory muscle work and the capacity to meet that demand in chronic obstructive pulmonary disease (COPD) can result in symptoms of dyspnea and the development of muscle fatigue. OBJECTIVES: The purpose of this study was to compare two different respiratory muscle endurance assessment methods of sustainable inspiratory pressure (SIP) and incremental threshold loading (ITL) in COPD. METHODS: Thirty-four patients diagnosed with COPD were included in the study. Physical and demographic characteristics of the subjects were recorded. Pulmonary function testing (PFT), modified Medical Research Council (MMRC) dyspnea scale, COPD assessment test, inspiratory and expiratory muscle strength (MIP and MEP, respectively) measurement and six-minute walk test (6MWT) were used to assess subjects. Two different respiratory muscle endurance tests (SIP and ITL) were performed within 48 hours apart, and each test was repeated two times on the same day. RESULTS: There was no correlation between the SIP and ITL tests (r = 0.069, P = .699). According to the test-retest reliability analysis, both tests were reproducible (ICC = 0.843; P < .001 for SIP, ICC = 0.905; P < .001 for ITL). Finding no differences between repeated tests showed that tests are not affected by learning effect. CONCLUSION: The SIP and ITL tests are used for the same purpose but have different characteristics. Regarding the relationship between the other parameters and tests, the ITL is well tolerated and reflects the differences in respiratory muscle endurance better.

Correlation of thrombosed vessel location and clot burden score with severity of disease and risk stratification in patients with acute pulmonary embolism.

OBJECTIVE: Computed tomography pulmonary angiography (CTPA) is used for the main diagnosis in acute pulmonary embolism (APE). Determining the thrombus location in the pulmonary vascular tree is also important for predicting disease severity. This study aimed to analyze the correlation of the thrombus location and the clot burden with the disease severity and the risk stratification in patients with APE. METHODS: The study included patients with APE diagnosed by CTPA who were admitted to the hospital between January 28, 2016, and July 1, 2019. Data collected were markers of severity in APE, including patient demographics, comorbidities, length of hospital stay, pulmonary embolism severity index (PESI) score, modified PESI score, Wells score, risk stratification according to the American Heart Association, systolic blood pressure (SBP), right ventricle diameter to left ventricle diameter ratio, pulmonary arterial pressure, brain natriuretic peptide, troponin, D-dimer, and plasma lactate levels, and vessel location of the thrombus, clot burden score, ratio of the pulmonary artery trunk diameter/aortic diameter, superior vena cava diameter (SVC) by CTPA, and survival. All parameters were analyzed in correlation with clot load and vessel location. RESULTS: Thrombus vascular location was found to be correlated with risk stratification and negatively correlated with SBP. Simplified Mastora score was correlated with risk stratification, SVC diameter, and D-dimer and negatively correlated with SBP. Occlusion of both the pulmonary artery trunk and any pulmonary artery with thrombus was associated with massive APE. CONCLUSION: The level of the occluded vessel on CTPA may provide the ability to risk-stratify, and the clot burden score may be used for assessing both risk stratification and cardiac strain.

Exercise Capacity and Activities of Daily Living are Related in Patients With Chronic Obstructive Pulmonary Disease / La capacidad de ejercicio y las actividades de la vida diaria están relacionada en pacientes con enfermedad pulmonar obstructiva crónica

INTRODUCTION: The knowledge of the relationship between exercise capacity and activities of daily living (ADLs) is important to minimize the negative outcomes in ADLs resulting from reduced exercise capacity in patients with chronic obstructive pulmonary disease (COPD). There is a limited study about the association between exercise capacity and ADLs in patients with COPD. This study aimed to investigate the relationship between maximal exercise capacity and ADLs in patients with GOLD stage II-III COPD. METHODS: Twenty-seven clinically stable GOLD stage II-III COPD patients were included (mean age = 58.59 ± 9.63 years and mean FEV1 = 50.6 ± 13.7%) in this cross-sectional study. Maximal and submaximal exercise capacity were evaluated using an incremental shuttle walk test (ISWT) and 6-min walk test (6 MWT), respectively. Activities of daily living were assessed using Glittre-ADL test. RESULTS: The ISWT distance was significantly correlated with Glittre-ADL test time (r = -0.517, p = 0.006). There was also a negative correlation between 6MWT distance and Glittre-ADL test time (r = -0.506, p = 0.007). CONCLUSION: A moderate relationship was found between maximal exercise capacity and general activities of daily living performance. The reduction in exercise capacity increases the negative influences in ADLs and strengthens our beliefs that exercise interventions in pulmonary rehabilitation could influence activities of daily living positively

INTRODUCCIÓN: Es importante conocer la relación entre la capacidad de ejercicio y las actividades de la vida diaria (ADL) para minimizar los resultados negativos de las ADL que resultan de una capacidad reducida de ejercicio en pacientes con enfermedad pulmonar obstructiva crónica (EPOC). Los estudios sobre la asociación entre la capacidad de ejercicio y las ADL en pacientes con EPOC son limitados. En este estudio se investigó la relación entre la capacidad máxima de ejercicio y las ADL en pacientes con EPOC de estadios GOLD grado II-III. MÉTODOS: Estudio transversal que incluyó a 27 pacientes clínicamente estables con EPOC de estadios GOLD grado II-III (edad media = 58.59 ± 9.63 años and FEV1 medio = 50.6 ± 13.7%). Las capacidades máxima y submáxima de ejercicio se evaluaron utilizando la prueba de lanzadera por tramos (ISWT) y la prueba de marcha de 6 minutos (6 MWT) respectivamente. Las actividades de la vida diaria se evaluaron mediante el test de Glittre-ADL. RESULTADOS: La distancia ISWT mostró una correlación significativa con el tiempo en el test Glittre-ADL (r = -0.517, p = 0.006). También se observó una correlación negativa entre la distancia en el 6MWT y el tiempo en la prueba de Glittre-ADL (r = -0.506, p = 0.007). CONCLUSIÓN: Se encontró una relación moderada entre la capacidad máxima de ejercicio y el desempeño general de las actividades de la vida diaria. La reducción en la capacidad de ejercicio aumenta las influencias negativas en las ADL y refuerza nuestras creencias de que las intervenciones con ejercicio tienen una influencia positiva en las actividades de la vida diaria en la rehabilitación pulmonar

Validity and Reliability of the Turkish Version of the London Chest Activity of Daily Living Scale in Obstructive Lung Diseases.

OBJECTIVES: The London Chest Activity of Daily Living Scale (LCADL) is a simple, useful, and comprehensive measure of dyspnea perception in activities of daily living. This study was conducted to determine the validity and reliability of the Turkish version of the LCADL. MATERIALS AND METHODS: A total of 64 patients with obstructive lung disease (24 chronic obstructive pulmonary disease, 20 asthma, and 20 bronchiectasis patients) were included. The Turkish LCADL was evaluated for interobserver reliability, test-retest reliability, and criterion validity. Two different observers applied the scale with an interval of 10 minutes to assess interobserver reliability. The second observer applied the scale twice at an interval of 10-15 days to assess test-retest reliability. Criterion validity was assessed using the 6-minute walk test (6MWT), Nottingham Health Profile (NHP), and Saint George Respiratory Questionnaire (SGRQ). RESULTS: The interobserver reliability of the scale was very high (rs=0.985, p<0.050). Cronbach's alpha coefficient for total score was 0.976 and intraclass correlation coefficient was 0.953. These results indicate that the Turkish LCADL has high reliability. The correlation between LCADL and 6MWT was moderate 0.503 (p=0.002). The LCADL total score was weakly correlated with NHP total score (rs=0.370, p=0.040) and SGRQ total score (rs=0.367, p=0.004). CONCLUSION: The Turkish version of the LCADL scale is reliable and valid in obstructive lung disease. The LCADL scale will be beneficial in existing pulmonary rehabilitation programs aiming to improve functional status. We believe that using the Turkish LCADL scale as an outcome measure in pulmonary rehabilitation programs will serve as an indicator of rehabilitation efficacy for individual patients.

Physical activity of patients with bronchiectasis compared with healthy counterparts: A cross-sectional study.

BACKGROUND: A few studies have implied that patients with bronchiectasis have a more inactive lifestyle than healthy counterparts do. The main objective of this study was to compare physical activity (PA) levels subjectively and objectively between patients with bronchiectasis and healthy individuals using an accelerometer and a questionnaire. METHODS: The study included 41 patients with bronchiectasis aged 18-65 years and 35 healthy age- and sex-matched control subjects. The PA level was assessed objectively using a multisensorial PA monitor, the SenseWear Armband (SWA), and subjectively with the International Physical Activity Questionnaire (IPAQ). All participants performed the incremental shuttle walk test (ISWT) for the assessment of exercise capacity. Pulmonary function, dyspnea, severity of bronchiectasis, respiratory and peripheral muscle strength, and quality of life were assessed. RESULTS: The pulmonary function test parameters, respiratory and peripheral muscle strength, exercise capacity, step count, moderate- and vigorous-intensity PA duration were significantly lower in patients with bronchiectasis than in the healthy control group (p < 0.05). Sedentary, moderate, vigorous, and total PA duration measured using the SWA were higher than those obtained using the IPAQ (p < 0.05). CONCLUSIONS: Patients with bronchiectasis have a reduced PA level compared with healthy counterparts. The IPAQ (based on the subjective estimation of PA) outcomes differed from the SWA outcomes, reinforcing the necessity for a disease-specific PA questionnaire. IPAQ underestimates the physical activity level compared with objective measurements.

Exercise Capacity and Activities of Daily Living are Related in Patients With Chronic Obstructive Pulmonary Disease.

INTRODUCTION: The knowledge of the relationship between exercise capacity and activities of daily living (ADLs) is important to minimize the negative outcomes in ADLs resulting from reduced exercise capacity in patients with chronic obstructive pulmonary disease (COPD). There is a limited study about the association between exercise capacity and ADLs in patients with COPD. This study aimed to investigate the relationship between maximal exercise capacity and ADLs in patients with GOLD stage II-III COPD. METHODS: Twenty-seven clinically stable GOLD stage II-III COPD patients were included (mean age=58.59±9.63 years and mean FEV1=50.6±13.7%) in this cross-sectional study. Maximal and submaximal exercise capacity were evaluated using an incremental shuttle walk test (ISWT) and 6-min walk test (6MWT), respectively. Activities of daily living were assessed using Glittre-ADL test. RESULTS: The ISWT distance was significantly correlated with Glittre-ADL test time (r=-0.517, p=0.006). There was also a negative correlation between 6MWT distance and Glittre-ADL test time (r=-0.506, p=0.007). CONCLUSION: A moderate relationship was found between maximal exercise capacity and general activities of daily living performance. The reduction in exercise capacity increases the negative influences in ADLs and strengthens our beliefs that exercise interventions in pulmonary rehabilitation could influence activities of daily living positively.
