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

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

Objective: The aim of the study is to describe the clinical characteristics of Antineutrophil cytoplasmic antibodies-associated vasculitis and to analyze the parameters affecting the outcome. Materials and Methods: The study is a retrospective cohort study. Totally 130 patients with Antineutrophil cytoplasmic antibodies-associated vasculitis (18 years and over) who were followed up between October 2014 and October 2019 were analyzed. Demographic data, laboratory values, clinical course, thorax computed tomography findings and treatment approaches were noted from the charts of patients. Patients were divided into two groups as those with pulmonary involvement and non-pulmonary involvement. Results: We retrospectively reviewed the medical records of 130 patients with Antineutrophil cytoplasmic antibodies-associated vasculitis; 111 with granulomatosis with polyangiitis, 15 with microscopic polyangiitis, 1 with eosinophilic granulomatosis with polyangiitis, and 3 with other types of vasculitis. The ratio of having the abnormality in thoracic computed tomography was 72.2%. There were 84 cases with pulmonary involvement and 46 cases with non-pulmonary involvement. The frequency of microscopic polyangiitis was significantly higher (p=0.034) in non-pulmonary involvement cases. There were 67 cases with proteinase 3 Antineutrophil cytoplasmic antibodies and 39 cases with myeloperoxidase Antineutrophil cytoplasmic antibodies positivity. Most of the cases with proteinase 3 Antineutrophil cytoplasmic antibodies positivity were classified as granulomatosis with polyangiitis, this was statistically significant. Recovery was referenced for the outcome. Any of the variables were found statistically significant effective on outcome. Conclusions: Cases with pulmonary involvement were more than the cases without pulmonary involvement in our study. microscopic polyangiitis was significantly higher in non- pulmonary involvement cases. We studied on a large group, and these significant findings may have important implications for the investigation, pathogenesis, and treatment of Antineutrophil cytoplasmic antibodies-associated vasculitis.

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.

Background 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. Methods 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. Results YKL-40 levels of pediatric and adult CF patients at all periods were significantly higher than controls (p

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.

Objective:The purpose of this study was to compare the respiratory functions, exercise performance, and quality of sleep in patients with Obstructive Sleep Apnea syndrome (OSAS) and Chronic Obstructive Pulmonary disease (COPD) compared to healthy individuals.Materials and Methods:Seventeen patients with OSAS (12 M, 5 F), 24 patients with COPD (20 M, 4 F) and 20 healthy subjects (15 M, 5 F) participated in this cross-sectional study. Respiratory function and muscle strength tests were performed. Knee extensors, shoulder abductors, and hand grip strength were measured in patients with OSAS and COPD using a digital hand-held dynamometer. Exercise performance was evaluated using a 6-minute walk test (6MWT), and sleep quality was assessed by the Pittsburgh Sleep Quality index (PSQI).Results:The 6MWT distance, 6MWT% distance, actual and percentage values of shoulder abductors muscle strength of patients with COPD were significantly lower than those of the OSAS group (p

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.

Pertussis is a vaccine-preventable disease that is transmitted from infected to susceptible individuals by respiratory route. Bordetella pertussis infection may occur at any age as neither vaccine nor natural infection induced immunity lasts life-long. This study was planned to demonstrate the serological evidence of infection among adults, to raise awareness among clinicians and to provide data for the development of strategies to protect vulnerable infants. A total of 538 patients (345 female, 193 male) ages between 18-87 years who had a complain of prolonged cough for more than two weeks were included in the study. Antipertussis toxin (PT) IgG and anti-filamentous hemagglutinin (FH) IgG levels from single serum samples were measured by an in-house ELISA test which was standardized and shown to be efficient previously. Anti-PT IgG antibody levels of >= 100 EU/ml were considered as acute/recent infection with B. pertussis. In our study, 9.7% (52/538) of the patients had high levels of anti-PT IgG (>= 100 EU/ml) and among those patients 43 (43/52; 82.7%) also had high (>= 100 EU/ml) anti-FHA IgG levels. There were no statistically significant differences in terms of age, gender, education level, DPT (diphtheria-pertussis-tetanus) vaccination history, smoking history or average daily cigarette consumption (p> 0.05) between the cases with high antibody levels (n=52). When the symptoms and the presence of cases with high antibody levels were evaluated, it was detected that no one parameter was significantly different from others, except that 24.1% of the cases with inspiratory whooping had high anti-PT levels. There was also no statistically significant difference between high anti-PT levels >= 100 EU/ml and the patients with risk factors [smoking (21/200; 10.5%), presence of disease that cause chronic cough and/or drug usage (19/171; % 11.1), and whole factors which cause chronic cough (32/306; % 10.5)] and without risk factors (p=0.581; p=0.357; p=0.249, respectively). The distribution of anti-PT IgG geometric mean titer (GMT) according to the age groups, was as follows; 32.41 in 18-30 years; 36.28 in 31-50 years; 36.82 in 51-70 years and 31.15 in >= 71 years. Our results indicated that B. pertussis infections are also present among adult population with a frequency not to be underestimated (9.7%) and the results also emphasized that since typical whooping cough symptoms may not be seen in adults, pertussis infection should be considered as a differential diagnosis in adults with prolonged cough, even if there are some other underlying factors of cough. The data obtained from this study was also considered to be helpful in the development of adult vaccination policies for the protection of infants who have not completed the vaccination schedule yet.

Objectives Chronic obstructive pulmonary disease (COPD) remains a globally significant cause of mortality, although COPD mortality varies from country to country, and across different regions within each country. The primary objective of this study was to determine the mortality rates of COPD patients who present with acute respiratory failure (ARF) to a tertiary care referral center in different stages of their follow-up (ICU, in-hospital and after discharge). The secondary objective was to determine factors associated with mortality in this group of patients. Results Medical records of consecutive COPD patients over a 10-year period were reviewed.The study included 147 patients. Of these, 72 were treated initially with noninvasive positive pressure ventilation (NIPPV), and 12 of these required intubation after NIPPV failed. Therefore, 86 patients were intubated for invasive mechanical ventilation (IMV), while NIPPV was succesful in 60 patients. Survival time was independently associated with advanced age, high APACHE II score, co-morbidity and the need for IMV. The cumulative mortality was 27% in the medical ICU and 31% in hospital following ICU discharge. The mortality rate at 1, 2 and 5 years was 54%, 66% and 84%, respectively. Conclusion COPD patients admitted to the ICU for ARF have an approximately 70% chance of leaving hospital alive, but half of these may die in the first 6 months after discharge. The risk factors related to mortality were advanced age, high APACHE II score, co-morbidity and IMV requirement.

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 (r(s)=0.985, p

Purpose: Dyspnea, cough and sputum are the main symptoms in obstructive pulmonary diseases. Along with these symptoms, fatigue is a very common but often ignored symptom. The aim of the present study was to determine and compare fatigue between patients with obstructive pulmonary disease and determine factors potentially associated with experience of fatigue in patients with obstructive pulmonary disease. Method: Twenty-four COPD, twenty asthma and twenty bronchectasis; total sixty-four patients diagnosed with obstructive pulmonary disease participated in this study. 6 minute walk test (6MWT) used to determine exercise capacity. All groups were assessed by all questionnaires following: Fatigue Impact Scale (FIS), International Physical Activity Questionnaire (IPAQ), Beck Depression Inventory, Nottingham Health Profile (NHP) and London Chest Activities of Daily Living Scale (LCADL). Results: Patients characteristics are presented in Table 1. According to Fatigue Impact Scale, all patients perceive fatigue and there was no statistically significant difference between groups (p>0.05). FIS has high correlation with SGRQ, NHP and Beck. There was moderate correlation between FIS and LCADL. Also, FIS has low correlation with IPAQ and 6MWT distance. (Table 2). Conclusion: This study demonstrates that obstructive pulmonary disease patients perceive fatigue. Fatigue perceptions of all three groups was statisticially similar but asthma and copd patients fatigue perceptions were more than bronchectasis patients. Experiences of fatigue has been associated with dyspnea perception in daily life activities, depression, physical activity level, functional capacity and therefore quality of life.

Background and objective Inspiratory muscle training (IMT) enhances velocity of inspiratory muscle contraction and modifies inspiratory and expiratory time. This study aimed to examine the impact of high-intensity IMT (H-IMT) on exercise capacity in bronchiectasis. Methods Forty-five patients were included. Lung function, respiratory muscle strength and endurance, exercise capacity, dyspnoea, fatigue and quality of life (QOL) were evaluated. Patients were randomized into two groups: H-IMT and control groups. Twenty-three patients underwent H-IMT for 8 weeks, using threshold loading with a target workload of maximal inspiratory pressure (MIP) of at least 70%, with 3-min cycles (as 2-min training: 1-min rest intervals) for 21 min. There was a total period of 14 min of loaded breathing and 7 min of recovery. The control group (n = 22) underwent low-intensity IMT at 10% of the initial MIP and was maintained at the same intensity until the end of the training. Results After training, both MIP and maximal expiratory pressure (MEP) and the incremental shuttle walk distance were increased in the H-IMT group compared with the control group (P < 0.05). There was a significant difference in constant threshold load, time and pressure-time units in the H-IMT group (P < 0.05) but not in the control group (P > 0.05). A significant decrease was found in fatigue in both groups (P < 0.05). The Leicester Cough Questionnaire social score for the H-IMT group decreased significantly after the treatment (P < 0.05). Conclusion The H-IMT increased exercise capacity in patients with non-cystic fibrosis bronchiectasis. It has also positive effects on respiratory muscle strength and endurance, and social aspects of QOL.

Objectives Arm strength training may improve functional performance for patients with chronic obstructive pulmonary disease (COPD). This trial investigated the effects of arm strength training on arm exercise capacity, activities of daily living (ADL) and occupational performance in patients with COPD. Methods These was a randomized controlled trial in an outpatient clinic. Forty-two stable patients with COPD were randomly assigned into treatment and control groups. The treatment group underwent an 8-week (23 sessions) arm strength training programme. Both groups completed daily breathing exercises at home. Tests included hand grip strength, arm ergometer test, the Glittre-ADL and ADL Simulation tests and measures included the Milliken ADL Scale (MAS) and the Canadian Occupational Performance Measure (COPM). Results Statistically significant increases were detected in hand grip strength and %hand grip strength values, peak arm ergometer workload and the number of ADL simulation test cycles for the treatment group (P

Objective: Pulmonary arterial hypertension (PAH) is a devastating complication of inflammatory rheumatic diseases. The aim of this study was to determine the role of screening for the early diagnosis of pulmonary hypertension (PH) in inflammatory rheumatic diseases. Material and Methods: Data of patients with inflammatory rheumatic diseases and PH who had no obvious cause of PH and who were evaluated by Working Group for Pulmonary Hypertension in Hacettepe University were investigated retrospectively. All patients with inflammatory disease were evaluated by right heart catheterization (RHC) to check if they had systolic pulmonary arterial pressure (sPAP) ≥40 mmHg and/or symptoms related to PH unless explained by other causes. Results: RHC was performed in 47 patients with inflammatory rheumatic diseases and PH out of 50 patients who were to be evaluated by RHC based on clinical and Doppler echocardiographic findings. There was a positive correlation between sPAP estimated by Doppler echocardiography and sPAP determined by RHC in patients with inflammatory rheumatic diseases (r=0.66; p

Introduction:Combination therapy with four drugs (isoniazid, rifampicin, pyrazinamid and ethambutol) is the treatment of choice in tuberculosis but hepatotoxicity due to these drugs is an important medical concern. Therefore identification of patient groups with increased risk for antituberculosis therapy induced hepatotoxicity is crucial.Material and Methods:This retrospective cohort study included hospitalized patients with the diagnosis of tuberculosis during a ten year period. Only patients with microbiological (culture positive) or histopathological (presence of granulomatous reaction with caseification necrosis in the tissue) evidence of tuberculosis infection were included. Incidence of hepatotoxicity and the association of hepatotoxicity with known and unknown risk factors were investigated.Results:Sixty four patients (33 female-31 male; median age 48.0 years) were included into the study. Most of the patients had extrapulmonary tuberculosis (n=49). Antituberculosis therapy was started with four drugs in all patients and 7 patients developed hepatotoxicity. Age, gender, previous tuberculosis history, extent of tuberculosis, positive hepatitis B virus serology, diabetes mellitus and chronic renal insufficiency were not related with the development of hepatotoxicity. The presence of rheumatologic disease and chronic corticosteroid use was associated with increased risk of hepatotoxicity (p

WOS: 000399794400008, PubMed ID: 29404162, Since the Global Initiative for Obstructive Lung Disease (GOLD) published its first guidelines on chronic obstructive pulmonary disease (COPD) in 2001, much has changed till 2017. Previous versions of GOLD guidelines mentioned the forced expiratory volume in one second (FEV1)-based approach for staging and treatment modalities. Since 2011, a composite multi-dimensional approach has been introduced to cover various aspects of the disease. Unfortunately, this approach was not found to be correlated with mortality as well as the FEV1 -based approach, despite the fact that it was better for estimating exacerbation rates. Although this assessment tool has been considered as a big step in personalized medicine, the system was rather complex to use in daily practice. In 2017, GOLD introduced a major revision in many aspects of the disease. This mainly includes a revised assessment tool and treatment algorithm. This new ABCD algorithm has excluded spirometry for guiding pharmacological therapy. Treatment recommendations are mainly based on symptoms and exacerbation rates. Escalation and de-escalation strategies have been proposed for the first time. The spirometric measurement has only been retained to confirm the diagnosis and lead to nonpharmacological therapies. In this report, the Turkish Thoracic Society COPD assembly aimed to summarize and give an insight to the Turkish interpretation of GOLD 2017.

The development of pulmonary hypertension (PH) and its effect on long-term survival in bronchiectasis subjects has not been explored. The present study aims to analyze the factors associated with PH and its effect on long-term survival in bronchiectasis subjects.We prospectively evaluated 23 bronchiectasis subjects without PH and 16 with PH, as well as 20 healthy volunteers.Bronchiectasis subjects with PH were more hypoxemic and had a greater number of involved lobes in high resolution computed tomography (HRCT) than did the bronchiectasis subjects without PH (P 0.001 and P 0.001, respectively). At three years, the survival rate was 95.7% for bronchiectasis subjects without PH and 56.3% for bronchiectasis with PH, and at 5 years, these rates were 95.7% and 62.5%, respectively (P = 0.002). Multivariate Cox regression analysis revealed that only the Medical Research Council (MRC) dyspnea score was independently related to poor survival in all bronchiectasis subjects (hazard ratio: 6.98; 95% CI: 2.41-20.23; P 0.00001).Subjects with PH are more hypoxemic and have a greater number of involvements in the lobes of the lungs. Bronchiectasis subjects with PH have worse survival than do bronchiectasis subjects without PH. MRC dyspnea score is an independent predictor of long-term survival.

Background and aims Fatigue is associated with longitudinal ratings of health in patients with chronic obstructive pulmonary disease (COPD). Although the degree of airflow obstruction is often used to grade disease severity in patients with COPD, multidimensional grading systems have recently been developed. The aim of this study was to investigate the relationship between perceived and actual fatigue level and multidimensional disease severity in patients with COPD. Materials and methods Twenty-two patients with COPD (aged 52-74 years) took part in the study. Multidimensional disease severity was measured using the SAFE and BODE indices. Perceived fatigue was assessed using the Fatigue Severity Scale (FSS) and the Fatigue Impact Scale (FIS). Peripheral muscle endurance was evaluated using the number of sit-ups, squats, and modified push-ups that each patient could do. Results Thirteen patients (59%) had severe fatigue, and their St George's Respiratory Questionnaire scores were significantly higher (p < 0.05). The SAFE index score was significantly correlated with the number of sit-ups, number of squats, FSS score and FIS score (p < 0.05). The BODE index was significantly associated with the numbers of sit-ups, squats and modified push-ups, and with the FSS and FIS scores (p < 0.05). Conclusions Peripheral muscle endurance and fatigue perception in patients with COPD was related to multidimensional disease severity measured with both the SAFE and BODE indices. Improvements in perceived and actual fatigue levels may positively affect multidimensional disease severity and health status in COPD patients. Further research is needed to investigate the effects of fatigue perception and exercise training on patients with different stages of multidimensional COPD severity.

Arm strength training may improve functional performance for patients with chronic obstructive pulmonary disease (COPD). This trial investigated the effects of arm strength training on arm exercise capacity, activities of daily living (ADL) and occupational performance in patients with COPD.These was a randomized controlled trial in an outpatient clinic. Forty-two stable patients with COPD were randomly assigned into treatment and control groups. The treatment group underwent an 8-week (23 sessions) arm strength training programme. Both groups completed daily breathing exercises at home. Tests included hand grip strength, arm ergometer test, the Glittre-ADL and ADL Simulation tests and measures included the Milliken ADL Scale (MAS) and the Canadian Occupational Performance Measure (COPM).Statistically significant increases were detected in hand grip strength and %hand grip strength values, peak arm ergometer workload and the number of ADL simulation test cycles for the treatment group (P 0.05). Significant decreases were also found in dyspnea and arm fatigue perception during arm ergometer test, and heart rate and dyspnea perception during Glittre-ADL test in the treatment group (P 0.05). The treatment group also showed significant increases in MAS-house cleaning and laundry and MAS-other activities integrated scores and COPM-performance and satisfaction scores (P 0.05).Arm strength training increases peripheral muscle strength, arm exercise capacity, ADL performance and patients' ADL performance satisfaction. Training decreases dyspnea and arm fatigue perception during supported arm exercises, and dyspnea perception during ADL. Arm strength training is a reliable and feasible treatment for COPD patients.

Chronic obstructive pulmonary disease (COPD) remains a globally significant cause of mortality, although COPD mortality varies from country to country, and across different regions within each country. The primary objective of this study was to determine the mortality rates of COPD patients who present with acute respiratory failure (ARF) to a tertiary care referral center in different stages of their follow-up (ICU, in-hospital and after discharge). The secondary objective was to determine factors associated with mortality in this group of patients.Medical records of consecutive COPD patients over a 10-year period were reviewed.The study included 147 patients. Of these, 72 were treated initially with noninvasive positive pressure ventilation (NIPPV), and 12 of these required intubation after NIPPV failed. Therefore, 86 patients were intubated for invasive mechanical ventilation (IMV), while NIPPV was succesful in 60 patients. Survival time was independently associated with advanced age, high APACHE II score, co-morbidity and the need for IMV. The cumulative mortality was 27% in the medical ICU and 31% in hospital following ICU discharge. The mortality rate at 1, 2 and 5 years was 54%, 66% and 84%, respectively.COPD patients admitted to the ICU for ARF have an approximately 70% chance of leaving hospital alive, but half of these may die in the first 6 months after discharge. The risk factors related to mortality were advanced age, high APACHE II score, co-morbidity and IMV requirement.

WOS: 000370844800007, PubMed ID: 29404083, Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality in the world. Research conducted over the past decade has contributed much to our current knowledge of the pathogenesis and treatment of COPD. Additionally, an evolving literature has recently accumulated information about the management of COPD and also about exacerbations. This article reviews a concise summary on the updates in COPD including 1) new pathogenic mechanisms and therapeutic targets, 2) management of patients in Group B, C and D according to GOLD 2014 report; 3) prevention and management of exacerbation; 4) monitoring of natural history; and 5) essential but usually forgotten parts of the management.

We conducted a cross-sectional survey in a cellulose plant among 109 reed workers, exposed to reed dust and 78 unexposed office workers, to investigate respiratory health effects of reed dust exposure. Investigations included dust measurements, serum total IgE, skin prick test, pulmonary function testing and questionnaire on respiratory symptoms. Total dust level in the reed processing unit was higher than the office (9.7 and 0.02 mg/m(3), respectively). Reed workers had a higher rate of current smoking (67% and 46%, respectively). After the adjustment for smoking status and age, reed dust exposure was significantly associated with wheezing, chronic cough, dyspnea, itching eyes and itching nose. Chest tightness and ODTS symptoms were only reported by reed workers (27.5% and 23.9%, respectively). After the adjustment for pack-years of smoking, percentage of predicted FEV1, FVC, FEV1/FVC and FEF25-75 in reed workers were significantly lower than office workers. Among reed workers, wheezing was associated with older age (> 40 years) and ever smoking, and cross-shift decline in FVC and FEV, with shorter duration of work. Reed dust exposure in the workplace could provoke respiratory symptoms, possibly due to an irritating effect. Health selection bias is likely, and could have underestimated the health effects of reed dust exposure. (c) 2004 Elsevier Ltd. All rights reserved.

Cancer-associated venous thromboembolism is a severe form of paraneoplastic syndrome. It rarely leads to venous gangrene. We report a case who presented with multiple deep venous thrombosis and venous gangrene of the lower extremity. During the follow-up period, the patient developed bilateral cervical and right supraclavicular lymphadenopathies. The fine needle aspiration of the lymph nodes revealed metastatic epidermoid carcinoma of an unknown primary. Thrombotic manifestations may complicate the clinicopathological course of malignancies.

A high body mass index (BMI) provides an advantage for survival in patients with chronic obstructive pulmonary disease (COPD). The aim of this study was to investigate the effects of obesity on respiratory muscle strength, exercise capacity, and physical activity level in patients with COPD. Twenty-eight male COPD patients (age: 63.07±6.32 years, FEV1: 36.9±11.0%) participated in this study. The subjects were divided into two groups as overweight/obese (25≤BMI≤34.9 kg/m2, n=14) and normal (18.5≤BMI≤24.9 kg/m2, n=14). Pulmonary function testing and six-minute walk test were performed. Respiratory muscle strength was evaluated using a portable mouth pressure device. Physical activity level of the subjects was determined using an accelerometer. Airway obstruction level was similar in both groups (p>0.05). Overweight/obese COPD patients’ inspiratory muscle strength (94.57±18.72 cmH2O), expiratory muscle strength (155.07±42.86 cmH2O), and physical activity level (319.3 kcal/day) were statistically higher than patients with a normal BMI (inspiratory muscle strength: 79.64±26.14 cmH2O, expiratory muscle strength: 124.36±23.70 cmH2O, and physical activity level: 275.9 kcal/days, p

Recent evidence suggests the presence of accompanying systemic inflammation in chronic inflammatory airway diseases such as chronic obstructive pulmonary disease and asthma; however little is known regarding the presence of systemic inflammation in bronchiectasis. Although bronchiectasis was initially considered a stationary process, chronic bacterial colonization causes airway inflammation and progressive airway damage. The aim of this study was to determine the level of systemic inflammation in bronchiectasis patients and identify its relationship with colonization. White blood cell (WBC) count, erythrocyte sedimentation rate, serum C-reactive protein (CRP), plasma fibrinogen, interleukin-8, tumor necrosis factor-alpha and leptin levels were determined in clinically stable bronchiectasis patients (n=50), and age- and sex-matched controls. Bronchiectasis patients were also analyzed according to colonization in sputum samples. There was no significant difference between bronchiectasis and control groups with respect to inflammatory markers but median (interquartile range-IQR) WBC count, CRP and fibrinogen levels were significantly higher in colonized patients (n=14) when compared to non-colonized patients [8.2 (6.4-9.5) vs. 6.4 (5.8-7.7) x 10(3)/mm(3), 0.91 (0.45-1.29) vs. 0.42 (0.30-0.77) mg/dL, 433.5 (390.3-490.3) vs. 392.0 (327.0-416.0) mg/dL, respectively; p

The aim of this study was to assess the relationship between cough-specific quality of life, abdominal muscle endurance, fatigue, and depression in stable patients with COPD.Methods: Twenty-eight patients with COPD (mean age 60.6±8.7 years) referred for pulmonary rehabilitation participated in this cross-sectional study. Sit-ups test was used for assessing abdominal muscle endurance. Leicester Cough Questionnare (LCQ) was used to evaluate symptom-specific quality of life. Fatigue perception was evaluated with Fatigue Impact Scale (FIS). Beck Depression Inventory (BDI) was used for assessing depression level.Results: The LCQ total score was significantly associated with number of sit-ups; BDI score; FIS total; physical, cognitive, and psychosocial scores (P

We investigated the factors determining self-efficacy in patients with chronic obstructive pulmonary disease (COPD).Thirty male patients with COPD and 30 healthy controls participated in the study. Pulmonary function tests, 6-minute walk test (6MWT), modified Borg scale, modified Medical Research Council (MRC) dyspnea scale, Hospital Anxiety and Depression Scale (HADS), Activities of Daily Living Questionnaire (ADL-Q), and COPD Self-Efficacy Scale (CSES) were used for the evaluation. The study was performed between September 2003 and May 2004 at the Department of Chest Medicine, School of Physical Therapy and Rehabilitation, Hacettepe University, Ankara, Turkey.The COPD patients expressed higher depression and dyspnea level and impaired activities of daily living than healthy controls (p0.05). Duration of disease and the ADL-Q score was significantly correlated with all subscales of CSES (p0.05). Borg score and anxiety score were significantly related with negative affect, weather/environment, and behavioral risk factors subscales of CSES (p0.05). Lung function was significantly related with physical exertion and behavioral risk factors, and 6MWT distance was significantly correlated with weather/environment and behavioral risk factors subscales (p0.05). The MRC score was correlated with weather/environment score (p0.05). The ADL-Q score and disease duration accounted for 76% of the variance in self-efficacy (p0.05)Level of impaired activities of daily living due to respiratory limitation and the number of years since diagnosis are independent variables that predict self-efficacy, or level of confidence in engaging specific behaviors that lead to specific desired outcomes in COPD.

To investigate the functional capacity in patients with severe chronic obstructive pulmonary disease (COPD) and healthy subjects.The present study was conducted in the School of Physical Therapy and Rehabilitation, Department of Chest Medicine, Medical School, Hacettepe University, Ankara, Turkey, from June 2002 to July 2003. Forty-five male patients with severe (23 moderately severe, 22 very severe) COPD and 45 healthy controls participated in the study. Pulmonary function tests and 6-minute walk test (6MWT) were performed. The Borg score and heart rate were measured before and after the test. External work of walking was calculated as the product of body weight and walked distance. Functional dyspnea was measured using the modified Medical Research Council (MRC) dyspnea scale.Both distance and external work of 6MWT were significantly lower in severe COPD patients than healthy subjects (p0.05). No significant differences in distance, external work, and exertional dyspnea were found between moderately severe and very severe COPD patients (p0.05). Patients with very severe impairment had a significantly lower percentage of predicted 6MWT distance (p0.05). In these patients, 6MWT distance was correlated significantly with forced expiratory flow in one second (FEV1), MRC score, and Borg score whereas external work of walking correlated with age, FEV1, forced expiratory flow from 25-75%, MRC, and resting Borg score (p0.05).Severe COPD patients had a significantly impaired functional capacity as compared to their healthy counterparts. Patients with FEV135% have a lower percentage of functional capacity. Both distance and external work of 6MWT are influenced by large and small airway function, level of breathlessness reported during daily activity or scored during an exercise test in patients with FEV135%.
