RESUMEN
INTRODUCTION: Long-acting muscarinic antagonists (LAMA) or beta-2 agonists (LABA) have been recommended for symptom control in group A COPD patients as a first-line bronchodilator treatment in GOLD guidelines. However, there is no mention of priority/superiority between the two treatment options. We aimed to compare the effectiveness of these treatments in this group. METHODS: The study cohort was formed of all subjects from six pulmonology clinics with an initial diagnosis of COPD who were new users of a LAMA or LABA from January 2020 to December 2021. Seventy-six group A COPD patients, in whom LABA or LAMA therapy had been started in the last 1 month as a first-line treatment, were included in our study. Participants were evaluated with spirometry, COPD Assessment Test (CAT), mMRC scale, and St. George Respiratory Questionnaire (SGRQ) for three times (baseline, 6-12th months). RESULTS: There were 76 group A COPD patients with LAMA (67.1%) and LABA (32.9%). The number of patients who improved in CAT score at the end of the first year was significantly higher in patients using LAMA than those using LABA (p = 0.022); the improvement at minimum clinically important difference (MCID) in CAT score of LAMA group at 1st year was also significant (p = 0.044). SGRQ total and impact scores were found to be statistically lower at 1st year compared to baseline in patients using LAMA (p = 0.010 and 0.006, respectively). Significant improvement was detected in CAT and SGRQ scores at the 6th month visit in the LAMA group having emphysema (p = 0.032 and 0.002, respectively). CONCLUSION: According to significant improvements in CAT and SGRQ score, LAMA may be preferred over LABA as a bronchodilator agent in group A COPD patients, especially in emphysema-dominant phenotype.

AIM: Chronic obstructive pulmonary disease (COPD) is primarily a respiratory system disorder associated with extrapulmonary conditions. Cognitive impairment (CoI) is very common among COPD patients This study sought to investigate the association between CoI and clinical parameters, inflammatory markers and lipid profiles in a COPD patient population. METHODS: The study population included 111 stable COPD patients. COPD was diagnosed according to Global Initiative for Chronic Obstructive Lung Disease guideline. Total complete blood count test and biochemical measurements including lipid profile were performed. Afterwards, all patients underwent neuropsychological assessment including Hospital Anxiety and Depression Scale (HADS), Pittsburgh Sleep Quality Index and Montreal Cognitive Assessment (MoCA) tests. RESULTS: The patients were categorized into two groups according to their MoCA test score: MoCA score ≤ 21 (CoI) (n = 69) and MoCA score > 21 (normal cognition) (n = 42). Total cholesterol (TC) levels were significantly lower in patients with CoI compared to patients with normal cognition. Inflammation related parameters including C-reactive protein were similar among groups. Multivariate logistic regression analysis yielded education, HADS score and TC (OR:1.02, 95% CI:1.00-1.04, p = 0.025) as independent predictors of MoCA score. CONCLUSION: TC independently associates with CoI in COPD patients. There is comparable inflammatory status in COPD patients with CoI compared to COPD patients with normal cognition.

PURPOSE: The aim of this study is to determine the diagnostic performances of pleural procedures in undiagnosed exudative pleural effusions and to evaluate factors suggestive of benign or malignant pleural effusions in tertiary care centers. METHODS: This was a multicenter prospective observational study conducted between January 1 and December 31, 2018. A total of 777 patients with undiagnosed exudative pleural effusion after the initial work-up were evaluated. The results of diagnostic procedures and the patients' diagnoses were prospectively recorded. Sensitivity, specificity, and accuracy estimates with 95% confidence intervals were used to examine the performance of pleural procedures to detect malignancy. RESULTS: The mean age ± SD of the 777 patients was 62.0 ± 16.0 years, and 68.3% of them were male. The most common cause was malignancy (38.3%). Lung cancer was the leading cause of malignant pleural effusions (20.2%). The diagnostic sensitivity and accuracy of cytology were 59.5% and 84.3%, respectively. The diagnostic sensitivity of image-guided pleural biopsy was 86.4%. The addition of image-guided pleural biopsy to cytology increased diagnostic sensitivity to more than 90%. Thoracoscopic biopsy provided the highest diagnostic sensitivity (94.3%). The highest diagnostic sensitivity of cytology was determined in metastatic pleural effusion from breast cancer (86.7%). CONCLUSION: The diagnostic performance increases considerably when cytology is combined with image-guided pleural biopsy in malignant pleural effusions. However, to avoid unnecessary interventions and complications, the development of criteria to distinguish patients with benign pleural effusions is as important as the identification of patients with malignant pleural effusions.

BACKGROUND: While mortality rates decrease in many chronic diseases, it continues to increase in COPD. This situation has led to the need to develop new approaches such as phenotypes in the management of COPD. We aimed to investigate the distribution, characteristics and treatment preference of COPD phenotypes in Turkey. METHODS: The study was designed as a national, multicenter, observational and cross-sectional. A total of 1141 stable COPD patients were included in the analysis. RESULTS: The phenotype distribution was as follows: 55.7% nonexacerbators (NON-AE), 25.6% frequent exacerbators without chronic bronchitis (AE NON-CB), 13.9% frequent exacerbators with chronic bronchitis (AE-CB), and 4.8% with asthma and COPD overlap (ACO). The FEV1 values were significantly higher in the ACO and NON-AE than in the AE-CB and AE NON-CB (p < 0.001). The symptom scores, ADO (age, dyspnoea and FEV1 ) index and the rates of exacerbations were significantly higher in the AE-CB and AE NON-CB phenotypes than in the ACO and NON-AE phenotypes (p < 0.001). Treatment preference in patients with COPD was statistically different among the phenotypes (p < 0.001). Subgroup analysis was performed in terms of emphysema, chronic bronchitis and ACO phenotypes of 1107 patients who had thoracic computed tomography. A total of 202 patients had more than one phenotypic trait, and 149 patients showed no features of a specific phenotype. DISCUSSION: Most of the phenotype models have tried to classify the patient into a certain phenotype so far. However, we observed that some of the patients with COPD had two or more phenotypes together. Therefore, rather than determining which phenotype the patients are classified in, searching for the phenotypic traits of each patient may enable more effective and individualized treatment.

BACKGROUND: Our aim is to determine the caregiver burden of chronic obstructive lung disease (COPD) patient's caregivers, and to determine whether there is a workday loss. METHODS: 252 COPD patients and their caregivers were included. Disease information of the patients were recorded and a questionnaire was applied. Socio-demographic characteristics of the caregivers were recorded and a questionnaire consisting of 24 questions including COPD disease, treatment and loss of working days, and the Zarit Scale were used. RESULTS: 128(50.8%) of the patients according to GOLD were group-D, 97(38.5%) of the patient's relatives were working, 62(24.7%) were not able to go to work for 1-14 days, and 125(57.1%) spent outside the home from 1-14 nights, because those accompanied to patients. In univariate analysis were detected modified medical research council (mMRC) (p < 0.001), CAT (p < 0.001), the number of comorbidities of patients (p = 0.027), forced expiratory volume in 1 FEV1cc (p = 0.009), FEV1% (p < 0.001), the presence of long term oxygen therapy (LTOT), and the number of comorbidities of the patient's relatives (p = 0.06) increased the care load. In multiple linear regression analysis, age (p = 0.03), COPD assessment test (CAT) score (p = 0.001), FEV1% (<0.068) and the number of comorbidities of patients (p = 0.01) and the number of comorbidities of caregivers (p = 0.003) increased the caregiving burden. DISCUSSION: In COPD increases caregiving burden. This burden is greater in symptomatic patients and when comorbidities are present. Psychosocial and legal regulations should be investigated and solutions should be produced for the caregivers of COPD patients.

BACKGROUND: After the first case of coronavirus disease 2019 (COVID-19) was reported in China in December 2019, it caused a global pandemic, including Turkey. OBJECTIVES: The aim of this study was to analyse the characteristics of hospitalised COVID-19 patients and assess the parameters related to severe pneumonia. METHODS: Included in the study were hospitalised COVID-19 patients with positive naso-oropharyngeal swabs. Patients' demographics, admission symptoms, laboratory and radiological findings were recorded retrospectively. RESULTS: Of 1013 patients, 583 were males (57.6%) and 430 were females (42.4%), with a mean age of 53.7 ± 17.9. More than half of the patients had at least one comorbidities, the most common of which were hypertension and diabetes mellitus. Cough (59.8%), fatigue (49.5%) and fever (41.2%) were the most common presenting symptoms. Of the hospitalised COVID-19 patients, 84.9% had pneumonia and 83.5% had typical radiological COVID-19 appearances (94.5%: ground-glass areas). The most common laboratory findings were high C-reactive protein (CRP) (73.6%) and lactate dehydrogenase (LDH) (46.2%) levels, as well as lymphopenia (30.1%). Severe pneumonia was present in 28.1% of COVID-19 patients. Multivariate logistic regression analysis indicated that advanced age, hypotension, anaemia and elevated CRP and LDH serum levels were independent risk factors for the severity of COVID-19 pneumonia (P = .011, .006, .017, .003 and .001, respectively). CONCLUSION: This study, as one of the first multicentre studies about characteristics of COVID-19 in Turkey, may guide about disease-related parameters and severity of pneumonia. Age, blood pressure, complete blood count and routine biochemical tests (including CRP and LDH) would appear to be important parameters for the evaluation of the severity of COVID-19 pneumonia.

INTRODUCTION: Pulmonary nodules are common incidental findings on computed tomography (CT). In Turkey, there is no available data about the follow-up of the frequency of incidental nodules. Our aim is to assess the frequency and size distrubition of incidental pulmonary nodule in our country. MATERIALS AND METHODS: Between January 2015 and December 2016, computed tomographies, taken of all outpatient and emergency department that recorded in the screening database were examined retrospectively. Nodules and their characteristics (number, size, density, localization) and relationship between age and gender were evaluated. RESULT: The age range of the cases was mean 58.99 ± 16.20 years, 256 (42.5%) were women and 347 (57.5%) were men. A total of 288 (48.25%) cases had 420 nodules. Solid nodule was present in 184 cases (30.5%). The number of cases with one solid nodule was 119 (64.7%). There were 124 solid nodules (55.36%) of ≥ 4-< 6 mm diameter, 64 solid nodules (28.57%) of ≥ 6-< 8 mm diameter and 36 solid nodules (16.07%) of ≥ 8 mm diameter. Nodule frequency increased statistically significantly with the age (p= 0.001). CONCLUSIONS: The frequency of incidental nodule was found higher than in our country than in developed countries.

Background/aim: Sonographic assessment of diaphragm structure and function would be a useful clinical tool in patients with chronic obstructive pulmonary disease (COPD). Our aim was to determine the muscle thickness of the diaphragm and the usefulness of clinical practice in patients with COPD. Materials and methods: The diaphragmatic thickness of 34 COPD patients and 34 healthy subjects was measured during tidal volume (Tmin) and deep inspiration (Tmax) on both sides using a B-mode ultrasound. The body mass index and the modified Medical Research Council (mMRC) index values were reported. Results: There was no correlation among TminR (P = 0.134), TminL (P = 0.647), TmaxR (P = 0.721), and TmaxL (P = 0.905) between the patients with COPD and the control group. There was also no significant difference between diaphragmatic thickness and COPD severity, respiratory function (P = 0.410), and frequency of exacerbations (P = 0.881) and mMRC (P = 0.667). Conclusion: Diaphragmatic dysfunction in COPD is related to mobility restriction rather than muscle thickness.

Background: Several studies have shown that the risk of mortality due to COVID-19 is high in patients with COPD. However, evidence on factors predicting mortality is limited. Research Question: Are there any useful markers to predict mortality in COVID-19 patients with COPD?. Study Design and Methods: A total of 689 patients were included in this study from the COPET study, a national multicenter observational study investigating COPD phenotypes consisting of patients who were followed up with a spirometry-confirmed COPD diagnosis. Patients were also retrospectively examined in terms of COVID-19 and their outcomes. Results: Among the study patients, 105 were diagnosed with PCR-positive COVID-19, and 19 of them died. Body mass index (p= 0.01) and ADO (age, dyspnoea, airflow obstruction) index (p= 0.01) were higher, whereas predicted FEV1 (p< 0.001) and eosinophil count (p= 0.003) were lower in patients who died of COVID-19. Each 0.755 unit increase in the ADO index increased the risk of death by 2.12 times, and each 0.007 unit increase in the eosinophil count decreased the risk of death by 1.007 times. The optimum cut-off ADO score of 3.5 was diagnostic with 94% sensitivity and 40% specificity in predicting mortality. Interpretation: Our study suggested that the ADO index recorded in the stable period in patients with COPD makes a modest contribution to the prediction of mortality due to COVID-19. Further studies are needed to validate the use of the ADO index in estimating mortality in both COVID-19 and other viral respiratory infections in patients with COPD.

Pulmonology is one of the branches that frequently receive consultation requests from the emergency department. Pulmonology consultation (PC) is requested from almost all clinical branches due to the diagnosis and treatment of any respiratory condition, preoperative evaluation, or postoperative pulmonary problems. The aim of our study was to describe the profile of the pulmonology consultations received from emergency departments in Turkiye. A total of 32 centers from Turkiye (the PuPCEST Study Group) were included to the study. The demographic, clinical, laboratory and radiological data of the consulted cases were examined. The final result of the consultation and the justification of the consultation by the consulting pulmonologist were recorded. We identified 1712 patients, 64% of which applied to the emergency department by themselves and 41.4% were women. Eighty-five percent of the patients had a previously diagnosed disease. Dyspnea was the reason for consultation in 34.7% of the cases. The leading radiological finding was consolidation (13%). Exacerbation of preexisting lung disease was present in 39% of patients. The most commonly established diagnoses by pulmonologists were chronic obstructive pulmonary disease (19%) and pneumonia (12%). While 35% of the patients were discharged, 35% were interned into the chest diseases ward. The majority of patients were hospitalized and treated conservatively. It may be suggested that most of the applications would be evaluated in the pulmonology outpatient clinic which may result in a decrease in emergency department visits/consultations. Thus, improvements in the reorganization of the pulmonology outpatient clinics and follow-up visits may positively contribute emergency admission rates.

BACKGROUND: COVID-19 is a disease associated with diffuse lung injury that has no proven effective treatment yet. It is thought that glucocorticoids may reduce inflammation-mediated lung injury, disease progression, and mortality. We aimed to evaluate our patient's characteristics and treatment outcomes who received corticosteroids for COVID-19 pneumonia. METHODS: We conducted a multicenter retrospective study and reviewed 517 patients admitted due to COVID-19 pneumonia who were hypoxemic and administered steroids regarding demographic, laboratory, and radiological characteristics, treatment response, and mortality-associated factors. RESULTS: Of our 517 patients with COVID-19 pneumonia who were hypoxemic and received corticosteroids, the mortality rate was 24.4% (n = 126). The evaluation of mortality-associated factors revealed that age, comorbidities, a CURB-65 score of ≥ 2, higher SOFA scores, presence of MAS, high doses of steroids, type of steroids, COVID-19 treatment, stay in the intensive care unit, high levels of d-dimer, CRP, ferritin, and troponin, and renal dysfunction were associated with mortality. CONCLUSION: Due to high starting and average steroid doses are more associated with mortality, high-dose steroid administration should be avoided. We believe that knowing the factors associated with mortality in these cases is essential for close follow-up. The use of CURB-65 and SOFA scores can predict prognosis in COVID-19 pneumonia.

INTRODUCTION: To examine the correlation of pulmonary functions and neutrophyle/lymphocyte ratio (NLR) with optic coherence tomography findings in stable chronic obstructive pulmonary disease (COPD). METHODS: Fifty-five COPD (110 eyes) and 48 control cases (96 eyes) were enrolled. COPD patients were grouped as Group 1 (mild-moderate) and Group 2 (severe) according to GOLD classification. Subfoveal choroidal thickness (SFCT), ganglion cell-inner plexiform layer (GCIP) and retinal nerve fiber layer (RNFL) analysis by SD-OCT were performed in follow up. NLR was calculated by blood cell count. RESULTS: Inferior RNFL and average GCIP of COPD were lower than control during the initial and sixth month examination (P = .002, P < .001, respectively). Average RNFL and SFCT were lower in COPD patients in sixth month examination (P = .020, P = .015, respectively). Average, temporal, inferior, nasal RNFL and SFCT in sixth month examination were significantly lower in severe COPD (P < .05 for all), but average GCIP were similar (P = .015). Disease duration, Modified Medical Research Council (mMRC) and attacks/year showed significant negative correlations, whereas forced expiratory volume in 1 second (FEV1) and FEV1/forced vital capacity (FVC) showed significant positive correlations with OCT values. NLR was significantly higher in COPD cases compared to control (P < .001) and had a negative correlation with GCIP values. CONCLUSION: Chronic obstructive pulmonary disease severity is shown to have a negative effect on OCT measurements. SD-OCT can reflect severity of inflammation, and suggested to be used in follow up of COPD cases. NLR may have a role to predict the ganglion cell damage in COPD patients.

OBJECTIVES: Dyspnea is a prominent symptom of chronic obstructive pulmonary disease (COPD). Patients with Global Initiative for Obstructive Lung Disease (GOLD) Stage C-D often complain of dyspnea, but the relationship between their level of dyspnea and their nutritional status has not yet been established. The aim of this study was to evaluate the dyspnea levels and nutritional status ofstable COPD patients in the out patient clinic. MATERIALS AND METHODS: Medical records including the Modified Medical Research Council (mMRC) Dyspnea Scale and the nutritional status of 41 patients were investigated in the study. The meanage of patients was 71.7±9.2 years. The Nutritional Risk Screening 2002 (NRS-2002) tool, body mass index (BMI), and mid-upper arm circumference were used to evaluate their nutritional status. We used correlation analysis to display the relationship between NRS-2002 score and MRC, COPD stage, and biochemical and anthropometric parameters indicating the nutritional status of patients. RESULTS: Out of the 41 COPD patients 87.8% (36) enrolled in the study were men and 12.2% (5) were women. The GOLD stages of the patients were 29.3% of patients with stage C and 70.7% with stage D. The risk of malnutrition (NRS ≥3) was detected in 48.8% of the patients, whereas 51.2% of patients (NRS<3) were risk-free. The mid-upper arm circumference of at risk patients was lower (25.6±3.2 vs 29.9±2.7 cm, p=0.032). The NRS-2002 score had a positive correlation with mMRC records (r=0.351, p=0.024). There was a statistically significant negative correlation between the NRS-2002 score and the mid-upper arm circumference (r=0.604, p<0.0001). Also, there was a negative correlation between BMI and mid-upper arm circumference (r=0.699, p<0.0001). CONCLUSION: The risk of malnutrition was common in stable COPD patients at the outpatient clinic, which seemed to adversely affect their dyspnea level. Therefore, while planning the treatment of COPD patients, evaluating their nutritional status and taking precautions accordingly contribute to the shortness of breath which is one of the most significant symptoms of the disease.
RESUMEN
OBJECTIVES: The aim of the study was to determine the prevalence of electrolyte and uric acid disturbances and their effects on mortality in patients with acute exacerbations of chronic obstructive pulmonary disease (AECOPD). MATERIALS AND METHODS: This study included all consecutive AECOPD patients who were managed at our Chest Diseases department between May 2017 and December 2017. Medical records of all the subjects were reviewed, and data were collected retrospectively. Eighty-one patients with AECOPD and 103 subjects in the control group were enrolled retrospectively. The association between the COPD and control groups and biochemical parameters in patients with and without long-term oxygen therapy and noninvasive mechanical ventilation treatment in COPD patients were compared with mortality. RESULTS: Serum magnesium, phosphorus, potassium, sodium, and calcium (Ca levels were higher in control subjects than in COPD patients (p=0.006, p=0.015, and p<0.001, respectively). While serum levels of Ca and K were significantly lower and serum level of uric acid was higher in deceased COPD patients than in alive AECOPD patients (p=0.023, p=0.001, and p=0.033, respectively), serum levels of Mg, P, and other biochemical parameters were similar. CONCLUSION: Serum Ca, K, and uric acid levels during the exacerbation period were significant predictors of mortality in COPD patients. In conclusion, the levels of these parameters should be measured and corrected during AECOPD treatment to decrease mortality.
RESUMEN
OBJECTIVE: To evaluate the short-term changes in subfoveal choroidal thickness (SFCT), ganglion cell complex (GCC) analysis, and retinal nerve fiber length (RNFL) of patients with chronic obstructive pulmonary disease (COPD) in a 3-month follow-up. MATERIALS AND METHODS: Forty-eight patients with COPD (96 eyes) and 40 control subjects (80 eyes) were enrolled in our study. COPD patients were grouped according to disease severity as Group 1 (mild-moderate) and Group 2 (advanced). GCC, RNFL, and SFCT analysis by Cirrus SD-OCT were obtained for all eyes, in two consecutive examinations with a 3-month interval. RESULTS: SFCT in Group 2 was lower than Group 1 and control group in the initial and 3rd month examination (p < 0.001, respectively). Inferior RNFL in Group 2 were lower than control group in the initial and 3rd month examination (p = 0.002, p < 0.001, respectively) Temporal RNFL were lower in Group 2 than Group 1 in 3rd month examination (p = 0.009). Average, superior, superotemporal, inferior, and inferonasal GCC analyses of the Group 2 were lower than control group both in the initial and 3rd month examination (p = 0.001, p < 0.001, respectively) SFCT, average, and superior GCC of Group 2 were significantly reduced during the 3-month follow-up (p < 0.001). CONCLUSION: Hypoxia is thought to be the underlying mechanism in COPD, which may influence retinal and choroidal OCT parameters. Decrease in blood flow of optic nerve head, increased vascular resistance, and reduced blood flow in choroid may affect the visual ability in these patients, which should be kept in mind during their follow-up.

OBJECTIVE: Cardiovascular diseases are the most common and important comorbidities in patients with chronic obstructive pulmonary disease (COPD). Literature indicates that there may be a relationship between diagonal earlobe crease (DELC) and coronary artery disease (CAD). Accordingly, the present study aimed to assess the relationship with DELC and cardiac comorbidities in patients with COPD during routine physical examination. MATERIALS AND METHODS: In this prospective cohort study, we evaluated the demographic data, pulmonary function test (PFT) results, lipid profile, oxygen saturation, and the presence of DELC in patients with COPD and control subjects. RESULTS: DELC was diagnosed in 155 (62%) of COPD patients and these patients had a higher prevalence of CAD (p = 0.044). Moreover, DELC was diagnosed in 135 men (68.5%) and 20 (37.7%) women in the COPD group (p<0.001) and in 39 (48.8%) men and 14 (56.0%) women in the control group (p = 0.527). On the other hand, CAD was diagnosed in 18% of patients with early-stage COPD (n = 104) and in 30.8% of patients with late-stage COPD (n = 146) (p = 0.041). The sensitivity and specificity of DELC positivity in predicting CAD were 80.65% and 44.15% in COPD patients, respectively. CONCLUSION: The presence of cardiac comorbidities in COPD patients may play a vital role in the severity of the disease, exacerbations, and may also reduce the treatment response. Accordingly, an earlobe examination of patients with COPD may be useful in predicting the presence of cardiac comorbidities with high sensitivity.

OBJECTIVE: Pneumonia is a leading cause of mortality worldwide, especially in the elderly. The use of clinical risk scores to determine prognosis is complex and therefore leads to errors in clinical practice. Pneumonia can cause increases in the levels of cardiac biomarkers such as N-terminal pro-brain natriuretic peptide (NT-proBNP). The prognostic role of the NT-proBNP level in community acquired pneumonia (CAP) remains unclear. The aim of this study was to evaluate the prognostic role of the NT-proBNP level in patients with CAP, as well as its correlation with clinical risk scores. METHODS: Consecutive inpatients with CAP were enrolled in the study. At hospital admission, venous blood samples were collected for the evaluation of NT-proBNP levels. The Pneumonia Severity Index (PSI) and the Confusion, Urea, Respiratory rate, Blood pressure, and age ≥ 65 years (CURB-65) score were calculated. The primary outcome of interest was all-cause mortality within the first 30 days after hospital admission, and a secondary outcome was ICU admission. RESULTS: The NT-proBNP level was one of the best predictors of 30-day mortality, with an area under the curve (AUC) of 0.735 (95% CI: 0.642-0.828; p < 0.001), as was the PSI, which had an AUC of 0.739 (95% CI: 0.634-0.843; p < 0.001), whereas the CURB-65 had an AUC of only 0.659 (95% CI: 0.556-0.763; p = 0.006). The NT-proBNP cut-off level found to be the best predictor of ICU admission and 30-day mortality was 1,434.5 pg/mL. CONCLUSIONS: The NT-proBNP level appears to be a good predictor of ICU admission and 30-day mortality among inpatients with CAP, with a predictive value for mortality comparable to that of the PSI and better than that of the CURB-65 score.

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is associated with increased cardiovascular morbidity and mortality. Carotid intima-media thickness (CIMT) is a noninvasive method assessing atherosclerosis. OBJECTIVE: It was aimed to determine relationship and survival between COPD and CIMT. METHODS: CIMT was measured using Doppler ultrasound (USG) in 668 stable COPD patients at 24 centers. Patients were followed-up for 2 years. RESULTS: There were 610 patients who completed the study. There were 200 patients CIMT with <0.78 mm (group 1), and 410 with CIMT ≥ 0.78 mm (group 2). There was a significant difference at the parameters of age, gender, smoking load, biomass exposure, GOLD groups and degree of airway obstruction (FEV1) between groups 1 and 2. Our results revealed positive correlations between mean CIMT and age, smoking load (pack-years), biomass exposure (years), exacerbation rate (last year), duration of hypertension (years) and cholesterol level; negative correlations between CIMT and FEV1 (P < 0.05). According to logistic regression model, compared with group A, risk of CIMT increase was 2.2-fold in group B, 9.7-fold in group C and 4.4-fold in group D (P < 0.05). Risk of CIMT increase was also related with cholesterol level (P < 0.05). Compared with infrequent exacerbation, it was 2.8-fold in the patients with frequent exacerbation (P < 0.05). The mean survival time was slightly higher in group 1, but not significant (23.9 vs 21.8 months) (P > 0.05). CONCLUSION: This study is the first regarding CIMT with combined GOLD assessment groups. It has revealed important findings supporting the increase in atherosclerosis risk in COPD patients. We recommend Doppler USG of the carotid artery in COPD patients at severe stages.

AIM: This study was undertaken to compare the clinical performance of right versus left double-lumen endotracheal tubes placed without using fiberoptic bronchoscopy in thoracic surgery operations. METHODS: This was a retrospective review of patients who were operated on in our institution between January 2013 and February 2014. We analyzed clinical performance in terms of hypoxia, hypercapnia, and adequate deflation of the lungs with both left- and right-sided double-lumen endotracheal tubes. RESULTS: There were 80 patients with a mean age of 53.74 ± 15.59 years. Right-sided double-lumen tubes were used in 33 patients, and left-sided double-lumen tubes were used in 47. Perioperative hypoxi (p < 0.05), hypercapnia (p < 0.01), and inadequate deflation of the lung (p < 0.001) were found more frequently with the use of right-sided double-lumen endotracheal tubes. Arterial blood gas analyses in the post-anesthesia care unit showed that high pCO2 (>45 mm Hg), low pH (<7.36), and high lactate levels (>4 mmol L(-1)) were more frequent with right-sided double-lumen endotracheal tubes (p < 0.001). The incidence of atelectasis was greater (p < 0.001) and the duration of hospital stay was longer (p = 0.02) with the use of right-sided double-lumen endotracheal tubes. CONCLUSION: Right-sided double-lumen endotracheal tubes resulted in poorer clinical performance. Therefore, a left-sided double-lumen endotracheal tube should be preferred in thoracic surgery operations when an appropriate size of fiberoptic bronchoscope is not available.

ABSTRACT Objective: Pneumonia is a leading cause of mortality worldwide, especially in the elderly. The use of clinical risk scores to determine prognosis is complex and therefore leads to errors in clinical practice. Pneumonia can cause increases in the levels of cardiac biomarkers such as N-terminal pro-brain natriuretic peptide (NT-proBNP). The prognostic role of the NT-proBNP level in community acquired pneumonia (CAP) remains unclear. The aim of this study was to evaluate the prognostic role of the NT-proBNP level in patients with CAP, as well as its correlation with clinical risk scores. Methods: Consecutive inpatients with CAP were enrolled in the study. At hospital admission, venous blood samples were collected for the evaluation of NT-proBNP levels. The Pneumonia Severity Index (PSI) and the Confusion, Urea, Respiratory rate, Blood pressure, and age ≥ 65 years (CURB-65) score were calculated. The primary outcome of interest was all-cause mortality within the first 30 days after hospital admission, and a secondary outcome was ICU admission. Results: The NT-proBNP level was one of the best predictors of 30-day mortality, with an area under the curve (AUC) of 0.735 (95% CI: 0.642-0.828; p < 0.001), as was the PSI, which had an AUC of 0.739 (95% CI: 0.634-0.843; p < 0.001), whereas the CURB-65 had an AUC of only 0.659 (95% CI: 0.556-0.763; p = 0.006). The NT-proBNP cut-off level found to be the best predictor of ICU admission and 30-day mortality was 1,434.5 pg/mL. Conclusions: The NT-proBNP level appears to be a good predictor of ICU admission and 30-day mortality among inpatients with CAP, with a predictive value for mortality comparable to that of the PSI and better than that of the CURB-65 score.
RESUMO Objetivo: A pneumonia é uma das principais causas de mortalidade no mundo, especialmente em idosos. O uso de escores de risco clínico para determinar o prognóstico é complexo e, portanto, leva a erros na prática clínica. A pneumonia pode causar aumento nos níveis de biomarcadores cardíacos, como o N-terminal pro-brain natriuretic peptide (NT-proBNP, pró-peptídeo natriurético cerebral N-terminal). O papel prognóstico do nível de NT-proBNP na pneumonia adquirida na comunidade (PAC) continua incerto. O objetivo deste estudo foi avaliar o papel prognóstico do nível de NT-proBNP em pacientes com PAC, bem como sua correlação com escores de risco clínico. Métodos: Pacientes consecutivos internados com PAC foram incluídos no estudo. Na internação hospitalar, foram coletadas amostras de sangue venoso para avaliação dos níveis de NT-proBNP. Foram calculados o Pneumonia Severity Index (PSI, Índice de Gravidade de Pneumonia) e o escore Confusão mental, Ureia, frequência Respiratória, Blood pressure (pressão arterial) e idade ≥ 65 anos (CURB-65). O desfecho primário de interesse foi mortalidade por todas as causas nos primeiros 30 dias após a admissão hospitalar, e um desfecho secundário foi admissão na UTI. Resultados: O nível de NT-proBNP foi um dos melhores preditores de mortalidade em 30 dias, com uma área sob a curva (ASC) de 0,735 (IC95%: 0,642-0,828; p < 0,001), assim como o PSI, que teve uma ASC de 0,739 (IC95%: 0,634-0,843; p < 0,001), enquanto CURB-65 teve uma ASC de apenas 0,659 (IC95%: 0,556-0,763; p = 0,006). O nível de corte do NT-proBNP que mostrou ser o melhor preditor de admissão na UTI e de mortalidade em 30 dias foi de 1.434,5 pg/ml. Conclusões: O nível de NT-proBNP parece ser um bom preditor de admissão na UTI e de mortalidade em 30 dias entre pacientes internados com PAC, com um valor preditivo para mortalidade comparável ao do PSI e superior ao do CURB-65.
