Antibiotic resistance rates and penicillin MIC distribution in patients with streptococcal pneumonia between 2013-2019, and use of antibiotics in clinical practice.

PURPOSE: The purpose of the present study is to investigate the antibiotic resistance rates and use of antibiotics in patients with streptococcal pneumonia in a reference tertiary care hospital for pulmonary diseases in Izmir, Turkey. METHODS: A total of 1224 cases with streptococcal pneumonia between 2013 and 2019 were included in the study, retrospectively. Drug susceptibility testing for penicillin and other antibiotics were performed according to the recommendations of EUCAST criteria. Clinical data and general characteristics were collected and evaluated for each patient in accordance with the susceptibility testing report. RESULTS: Totally, resistance rates for trimethophrim-sulfamethoxazole, penicillin (oxacillin), erythromycin, tetracycline, clindamycin and levofloxacin resistance were 63.5%, 39.8%, 37.7%, 37.6%, 28.8%, and 4.8%, respectively. Antibiotic resistance was not detected against vancomycin,teicoplanin and linezolid. Multidrug resistance rate was found to be 27.1%. It was observed that there was a statistically significant decrease in trimethophrim-sulfamethoxazole, penicillin (oxacillin), erythromycin, clindamycin and levofloxacin resistance rates by years (p: 0.000, 0.004, 0.000, 0.001, 0.010, respectively). The penicillin MIC distribution was higher at the range of 0.12-2 â€‹µg/mL and there was statistical difference among the ranges of MIC values for the representative years (p:0.033). Among the antibiotics investigated, the most commonly used antibiotic was moxifloxacin. CONCLUSIONS: Trimethophrim-sulfamethoxazole resistance rate has been found higher than other antibiotics. As penicillin MIC values were at the range of 0.12-2 â€‹µg/mL frequently, high doses of penicillin treatment might be required in some patients. It is noteworthy that significant decrease in resistance rates in penicillin, erythromycin, clindamycin and tetracycline could be due to the vaccination programme carried out since 2008 in Turkey. As the empiric use of quinolones is high it would be more appropriate to use it according to the susceptibility testing. It is important to determine the regional antimicrobial susceptibility for Streptococcus pneumoniae to select appropriate empirical antimicrobials in the clinical practice.

Clinical Differences Between Elderly and Non-elderly Patients with COVID-19.

OBJECTIVE: Comorbidity frequency and mortality rates are higher in elderly patients with COVID-19. The disease is also more severe in elderly patients. This study aims to examine the characteristics of the COVID-19 disease, severity, comorbidities, and mortality rates in elderly patients by comparing them with nonelderly patients. MATERIAL AND METHODS: This study was designed as a retrospective study. 469 patients who were followed up in outpatient, inpatient, and intensive care units with the diagnosis of COVID-19 between March 11, 2020, and June 01, 2020, were retrospectively included in the study. Patients were divided into two groups who were ≥65 years named as the "elderly group" and <65 years referred to as "nonelderly". Survival data was generated from the death notification system on August 02, 2020. RESULTS: A total of 469 patients including elderly(n=101) and nonelderly(n=368) were included in the study retrospectively. The inci- dence of severe pneumonia(31%/12.6%) and critical illness(16%/5.8%), comorbidity (85%/37.2%) and hospitalization time(8/5 days) were significantly higher in the elderly group(p<0.05). 23 (22.8%) of elderly patients and 27(7.3%) of nonelderly patients died (p=0.000). Mortality was found to be 3.5 times higher than in the non-elderly group. The expected survival time was 145.85 days(CI 95%:133- 158.66) in the elderly patients and 170.36 days(CI 95%:166-174.6) in the nonelderly patients (p<0.000). In ROC analysis, the sensitivity of age was 86%(73.3-94.2), specificity was 66.83%(62.1-71.3), and the cut-off>56 (AUC:0.775; p <0.001) in predicting mortality. CONCLUSION: Mortality is high, comorbidities are more frequent, and the disease is more severe in elderly patients with COVID-19. Age above 56 can be used as a cut-off to predict mortality.

Relationship between 18F-FDG PET/CT radiometabolic markers and EGFR mutation, positive ALK Expression in patients with non-small cell lung cancer.

INTRODUCTION: The aim of this study was to evaluate the association between the presence of EGFR mutations, ALK rearrangement and the standardized uptake value (SUV) of 18F-fluoro-2-deoxy-glucose (18F-FDG) by PET/CT imaging in patients with NSCLC. MATERIALS AND METHODS: We retrospectively reviewed NSCLC patients, who underwent EGFR mutation, ALK rearrangement testing and pre-treatment PET/ CT. The relationships of EGFR mutation, ALK rearrangement with patient characteristics and three parameters based on 18F-FDG PET/CT, including the maximal standard uptake value (SUVmax) of the primary tumour (tSUVmax), lymph node (nSUVmax) and distant metastasis (mSUVmax) were evaluated. RESULT: EGFR mutations were found more frequently in females and nonsmokers. tSUVmax was the only PET parameter that was lower in EGFRpositive patients than in EGFR-negative patients (8.7 vs. 11), with a p value of 0.032. There were no differences between nSUVmax and mSUVmax results and EGFR mutation. tSUVmax, nSUVmax and mSUVmax were not significantly different between ALK positive and ALK negative groups in NSCLC. The presence of pleural fluid at the time of diagnosis was significantly associated with positive ALK expression. CONCLUSIONS: We showed that low tSUVmax and primary tumour diameter were associated with mutant EGFR status and could be evaluated with other clinical factors to increase the discrimination in EGFR mutation status in some NSCLC patients without EGFR testing. There is a correlation between ALK positivity and the presence of pleural fluid. We also noted that the ALK positivity might be only in the adenocarcinoma group and at a younger age.

Can LENT Prognostic score (LDH, ECOG performance score, blood neutrophil/lymphocyte ratio, tumor type) change the clinical approach in malignant pleural effusion?

INTRODUCTION: The aim of this study was to evaluate the predictive power of LENT (LDH in pleural fluid, Eastern Cooperative Oncology Group [ECOG] performance status, neutrophil-lymphocyte ratio in the serum, and tumor type) score which is a current prognostic score in patients with MPE and to determine its effect on survival and its status in clinical decision making. In addition, it was aimed to compare LENT score with the conventional but subjective score ECOG. MATERIALS AND METHODS: A retrospective observational study was conducted reviewing the medical records of patients managed for MPE (malign pleural effusion) between 2008 and 2018. LENT prognostic score was calculated in the patients. The ECOG score calculated for the same patients was compared in terms of mortality. RESULT: A total of 191 patients with malignant pleural effusion, 118 males (61.7%) and 73 females (38.2%), were included in the study. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for identifying overall survival were 69.8 %, 100%, 100% and 18.8%, respectively at the LENT score > 4 (p= 0.000). At ECOG PS >2, the sensitivity, specificity, PPV, NPV were as the same as the LENT score >4 for identifying overall survival. In all patients, overall median survival according to the LENT score was 662/119/33 days in low/moderate/high risk groups, respectively. Cox regression analysis indicated that having a moderate LENT score (p= 0.004, OR: 2.21, CI: 1.29 -3.78%) and high LENT score (p= 0.000, OR: 4, 50 CI: 2.57-7.89%) were predictors for overall survival in all patients due to MPE. In ROC analysis, there was no difference in mortality in erms of both LENT and ECOG at 1st, 6th and 12th months. CONCLUSIONS: LENT is a better scoring system than ECOG in predicting early mortality, while both ECOG and LENT have almost the same power in predicting mortality. However, LENT is slightly more objective but more difficult to calculate because it contains laboratory findings. Thus, both scoring systems can be used to predict mortality in patients with malignant pleural effusions. Neither of them has superiority to each other.

Comparison of the diagnostic efficacy and complications of transbronchial biopsy in elderly and young patients.

INTRODUCTION: Among bronchoscopic procedures, transbronchial biopsy (TBB) is considered a high-risk procedure. In this study, we aimed to investigate the indications, diagnostic efficacy and complications of TBB in the elderly, which is accepted as a sensitive group. MATERIALS AND METHODS: The study was designed as a multicenter retrospective observational study. Data of 4226 patients who underwent diagnostic bronchoscopy were scanned for this study. 791 patients who underwent transbronchial biopsy were included in this study. All patients were evaluated in terms of lung regions, diagnosis, and complications. RESULT: A total of 791 patients, 329 (41.6%) female patients, who underwent TBB were included in the study. Mean age of the patients was 54.54 ± 14.94 years. The most common indications were ILD (45.6%), malignancy (24.0%) and sarcoidosis (9.9%). Mean age of the elderly patients (n= 263) was 69.89 ± 4.83 years, and mean age of the young patients (n= 528) was 46.90 ± 11.28 years (p<0.001). In both age groups, the most common indication was ILD. Complications developed during and after the procedure in 51 of the young patients (9.7%) and in 21 of the elderly (8.0%) (p= 0.441). The most common complication was pneumothorax with 4.6% in the elderly, and pneumothorax with 5.9% in the young (p= 0.441). The most common diagnosis was malignancy (12.2%) in the elderly, as the most common diagnosis was malignancy (7.2%) in the young (p = 0.020). While anthracosis, ILD and organized pneumonia were the other common diagnoses in the elderly, sarcoidosis, anthracosis and organized pneumonia were the other common diagnoses in the young. The diagnosis of sarcoidosis was achieved more frequently in the young (6.6%) than in the elderly (0.8%) (p<0.001). CONCLUSIONS: Transbronchial biopsy can be performed safely in elderly patients, with similar diagnostic success and complication rates to younger patients.

[A rare carcinoma metastasizing to the lung: Sertoli-leydig cell tumor]. / Akcigere metastaz yapan nadir bir karsinom: Sertoli-leydig hücreli tümör.

The lung is the most common site of metastasis for many malignancies. Especially the gastrointestinal system, gynecological malignancies and osteosarcomas frequently metastasize to the lung. It accounts for less than 0.5% of all ovarian neoplasms. The frequency of recurrence and metastasis is less than 5%. In most cases, they are stage I tumors, limited to the ovary and carry a good prognosis. Here, while investigating the nodules in the lung that were detected incidentally at the age of 64, the rare Sertoli-Leydig cell tumor of the lung is discussed clinically, radiologically and pathologically in the presence of a 64-year-old patient who was found to have undergone ovarian surgery 9 years ago. Since imaging methods and tumor markers did not yield significant results in terms of primary malignancy, wedge resection was performed from the left lung nodules. The histology of the lung nodule was the same as the poorly differentiated foci of the ovarian tumor. The immunohistochemical profiles of the two tumors were also similar. As a result of the evaluation of the patient's old materials belonging to the ovary and the samples taken from the lung together; The diagnosis was reached by obtaining similar results with the primary tumor in the immunohistochemical examination performed for the metastatic focus. Sex cord stromal tumors of the ovary, which rarely cause lung metastasis and have a tendency to recur and metastasis in a very long time after the first diagnosis, should also be kept in mind in the elderly woman and the patient with a gynecological history.

Pneumomediastinum as a complication of COVID-19 disease: A case report.

As the COVID-19 pandemic progresses, awareness of uncommon presentations of the disease increases. Such is the case with pneumomediastinum. Recent evidence has suggested that these can occur in the context of COVID19 pneumonia, even in the absence of mechanical ventilation-related barotrauma. We present a patient with COVID-19 pneumonia complicated by pneumomediastinum.

Can the Level of CRP in Acute Pulmonary Embolism Determine Early Mortality?

OBJECTIVE: The purpose of this study was to determine the prognostic role of C-Reactive Protein (CRP) in acute PE. MATERIAL AND METHODS: Two hundred and twenty patients with acute PE were consecutively enrolled and followed for 30 days after discharge. Serum CRP and NT-proBNP were determined. Right ventricular function was evaluated by transthoracic echocardiography. RESULTS: There was a significant difference in age, S-PESI, and CRP levels between the early mortality group and without early mortality group. There was statistically no significant difference between the groups with and without early mortality in terms of gender distribution and whether or not they received thrombolytic therapy for DVT. Pulmonary infarct, pleural fluid, or both have no effect on early mortality. There was no correlation between CRP and pro-BNP, right/left ventricular ratio. The serum CRP levels at diagnosis were significantly higher in patients with PE and with pleural effusion and pulmonary infarct than those in PE patients without pleural effusion and pulmonary infarct (4.75±4.91 ng/mL, 9.67±8.02 ng/mL; p<0.0003). CONCLUSION: High levels of CRP owing to inflammation in pulmonary embolism associated with effusion and infarction reveals why early mortality is significant in this group. CRP may help in the risk stratification of patients with acute PE, especially those with effusion and pulmonary infarction. CRP is an inexpensive and easily applicable biochemical marker, which can be used to predict early mortality.

Comparison of typical and atypical computed tomography patterns regarding reversibility and fibrosis in pulmonary sarcoidosis.

PURPOSE: This study aims to investigate whether there is a significant difference between typical and atypical parenchymal patterns in the development of fibrosis, which is the most crucial factor affecting morbidity in pulmonary sarcoidosis. METHODS: In our hospital, 145 cases with Siltzbach Types 2 and 3 sarcoidoses diagnosed by clinical, radiological, and histopathologic were retrospectively investigated. Perilymphatic nodules, accompanying mosaic attenuation, and interlobular septal thickening and central peribronchovascular bunch-like thickening on high-resolution computed tomography were assessed as typical. Solid nodules, galaxy finding, consolidation, ground-glass opacity, isolated mosaic attenuation, and interlobular septal thickening, and pleural fluid were accepted as atypical findings. Findings indicating fibrosis were fine and rough reticular opacity, traction bronchiectasis, volume loss, and cystic changes. For the analysis of variables, SPSS 25.0 program was used. RESULTS: Ten (16%) of the 61 cases with typical findings and 16 (19%) of the 84 with atypical findings developed fibrosis (P = 0.827). The mean age of cases with fibrosis was higher. With the cut-off of 50 years, sensitivity was 61.5%, and specificity was 68.9%. The highest fibrosis rate was in cases with ground glass pattern (n = 7/17), whereas higher reversibility rates were in those with miliary pattern (n = 9/12) and galaxy sign (n = 5/6). CONCLUSION: The incidence of fibrosis is higher in the atypical group with no significant difference. The incidence of fibrosis differs in each atypical pattern, being highest in ground-glass opacity and lowest in the miliary pattern.

What are the Differences Between Smoker and Non-smoker COPD Cases? Is it a Different Phenotype?

OBJECTIVE: The most important risk factor for chronic obstructive pulmonary disease (COPD) is smoking. However, more than 25% of patients do not have a history of smoking. The intent of this study is to identify characteristics of COPD patients that are non-smokers. MATERIAL AND METHODS: The records of patients with COPD were retrospectively reviewed. Smoking history, comorbidities, exacerbations, biomass, and environmental tobacco smoke (ETS) exposures were identified. Also, age, gender, pulmonary function test (PFT) values, modified Medical Research Council (mMRC) dyspnea scores were recorded. Non-smokers exposed to any of the COPD risk factors above were grouped and the data were analyzed to determine the specific characteristics of COPD that applied to them. RESULTS: A total of 706 COPD patients were analyzed with a mean age of 67.2 ± 9.4. Of these patients, 93 (13.2%) were female and 613 (86.8%) were male. Of the 706 patients, 128 (18.1%) were non-smokers. The percentage of male patients having COPD was significantly lower in the non-smoker group (P < .001). However, biomass, ETS exposure in childhood, and a history of previous respiratory infection were significantly higher in the non-smoker group (P < .001). The mean body mass index (BMI) was greater in non-smokers than smokers. CONCLUSION: Non-smokers with COPD have more biomass, ETS exposure, and infection history in childhood. They also have less impairment of airflow limitation, better symptom scores, and greater BMIs. Smoking history can be used to determine a different phenotype.

Value of Cancer Ratio plus and Cancer Ratio Formulation in Distinguishing Malignant Pleural Effusion from Tuberculosis and Parapneumonic Effusion.

Background: The aim of our study is to determine the clinical availability accessibility of cancer ratio and cancer ratio plus formulations, previously validated and reported to have clinical value in distinguishing malignant pleural effusion from tuberculosis pleurisy and parapneumonic effusion. Materials and Methods: Retrospective study of patients hospitalized with Malignant Pleural Effusion (MPE), tuberculosis (TPE) and pararapneumonic effusion (PPE) between 2009 and 2018. Results: Totally 232 patients, 101(43.5 %) having MPE, 86 (37.1 %) having PPE and 45 (19.4 %) TPE were examined. When compared with each other, "serum LDH / PS Lymphocyte %", "Cancer ratio" and "Cancer ratio plus" values were statistically different between the groups (p = 0.021, p <0.001 and p = 0.015, respectively). In multivariate logistic regression analysis, cancer ratio, serum LDH: pleural fluid lymphocyte count ratio was in positive correlation with MPE. The sensitivity and specificity of "cancer ratio", "cancer ratio plus" and "ratio of serum LDH: pleural fluid lymphocyte count" were 84.2 % (95% CI 75.6- 90.7) and 52.7 (95% CI 43.8- 61.5), and 82.2 % (95% CI 73.3- 89.1) and 45.8 (95%CI 37.1- 54.7), 53.5% (95% CI 43.3- 63.5) and 67.2% (95% CI 0.68-0.94) at the cut-off level of >14.25, >28.7, and >636, respectively. When considering only MPE and TPE patients, the specificity of cancer ratio and cancer ratio plus increased. Conclusion: The cancer ratio plus rate (the ratio of "cancer ratio"formulation to the percentage of differential pleural lymphocyte count) was almost the same as the cancer ratio in separating the malignant pleural effusion from the TPE and PPE, while it has better specificity only in differentiating malignant effusions from tuberculosis effusions.

Clinical presentation of health care workers with symptoms of coronavirus disease 2019 at the Izmir tertiary education hospital, during an early phase of the pandemic.

INTRODUCTION: The aim of this study is to investigate and report on the data regarding the clinical characteristics and outcomes of healthcare workers with COVID-19 at tertiary education hospitals from Turkey. MATERIALS AND METHODS: This was a single center, retrospective, descriptive and observational study using cross-sectional data, which were collected from confirmed COVID-19 patients at a tertiary education hospital. Patients' demographic and clinical characteristics, mortality rates, and the factors associated with hospitalization were analyzed. RESULT: By May 15, 2020, 480 patients were diagnosed with COVID-19 in our hospital where 49 (10.2%) of whom were HCWs. The mean age was 40.0 ± 8.45 (75.5% female). The most common symptoms were cough (32.7%), fever (30.6%), and myalgia (14.3%). Comorbidities were present in 32.7% of the patients. Most of the HCWs were nurses (53.1%) and physicians (18.4%), and the remaining 14 (28.6%) were cleaning and administrative staff. The severity of the disease was mild in 65.3% and severe in 34.7% HCWs. Leukocyte, neutrophil, lymphocyte and platelet values were statistically lower in hospitalized patients. There was a statistically significant relationship between the presence of infiltration on the chest X-ray, and the patient's symptoms with the severity of the disease (respectively p= 0.002 and 0.009). CONCLUSIONS: In conclusion, the frequency of COVID-19 in healthcare workers is high. The study presents the characteristics of HCWs infected with coronavirus from a single center in Turkey.

Contribution of Cell Block Obtained by Thoracentesis in the Diagnosis of Malignant Pleural Effusion.

AIM: The aim of this study wass to compare the cytological features of pleural exudative fluids by conventional smear (CS) method and cell block (CB) method and also to assess the utility of the combined approach for cytodiagnosis of these effusions. MATERIALS AND METHODS: In all, 113 pleural exudative fluid samples were subjected to evaluation by both CS and CB methods over a period of 2 years. Cellularity, architecture patterns, morphological features, and yield for malignancy were compared, using the two methods. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy for diagnosis of malignancy were calculated for both the methods, using histology as a gold standard. RESULTS: CB method provided higher cellularity, better architectural patterns, and additional yield for malignancy when compared with CS method. For 22 (40%) patients, histologic subtype was determined with CB especially for adenocarcinoma. The sensitivity, specificity, positive, and negative predictive values of cytology and CB were 48%, 100%, 100%, 67.8% and 59.2%, 100%, 100%, 72.8%, respectively. CONCLUSION: CB technique definitively increased detection of malignancy in pleural fluid effusion when used as an adjunct to CSs. Also, CB provides material suitable for molecular genetic analysis for targeted therapies especially in the treatment of adenocarcinoma.

Immunization status in chronic obstructive pulmonary disease: A multicenter study from Turkey.

OBJECTIVE: The purpose of this study is to detect the prevalence and the factors associated with influenza and pneumococcal vaccination and outcomes of vaccination during 2013-2014 season in patients with chronic obstructive pulmonary disease (COPD) in Turkey. METHODS: This was a multicenter retrospective cohort study performed in 53 different centers in Turkey. RESULTS: During the study period, 4968 patients were included. COPD was staged as GOLD 1-2-3-4 in 9.0%, 42.8%, 35.0%, and 13.2% of the patients, respectively. Influenza vaccination rate in the previous year was 37.9%; and pneumococcus vaccination rate, at least once during in a life time, was 13.3%. Patients with older age, higher level of education, more severe COPD, and comorbidities, ex-smokers, and patients residing in urban areas had higher rates of influenza vaccination. Multivariate logistic regression analysis showed that advanced age, higher education levels, presence of comorbidities, higher COPD stages, and exacerbation rates were associated with both influenza and pneumococcal vaccination. The number of annual physician/outpatient visits and hospitalizations due to COPD exacerbation was 2.73 ± 2.85 and 0.92 ± 1.58 per year, respectively. Patients with older age, lower education levels, more severe COPD, comorbid diseases, and lower body mass index and patients who are male and are residing in rural areas and vaccinated for influenza had significantly higher rates of COPD exacerbation. CONCLUSIONS: The rates of influenza and pneumococcal vaccination in COPD patients were quite low, and the number of annual physician/outpatient visits and hospitalizations due to COPD exacerbation was high in Turkey. Advanced age, higher education levels, comorbidities, and higher COPD stages were associated with both influenza and pneumococcal vaccination.

A promising tool for T-staging of lung cancer: Is convex probe endobronchial ultrasound superior to computed tomography in detecting invasion of mediastinal and hilar vessels?

BACKGROUND: In the present study, we aimed to compare performance of convex probe endobronchial ultrasound and computed tomography in detecting vascular invasion of mediastinal and hilar lesions. METHODS: Medical data of a total of 55 patients (47 males, 8 females; mean age 59.6±7.7 years; range, 29 to 76 years) who underwent convex probe endobronchial ultrasound for diagnosis and staging of lung cancer in a tertiary care hospital between May 2016 and December 2017 were retrospectively analyzed. The presence of vascular invasion was determined according to two main criteria: visualization of the tumor tissue within the vessel lumen and loss of vessel-tumor hyperechoic interface. All available contrast enhanced computed tomography images were retrospectively re-evaluated by a blinded radiologist. The intra-rater agreement between convex probe endobronchial ultrasound and computed tomography was analyzed. The sensitivity, specificity, positive and negative predictive values, and accuracy of both modalities were calculated. RESULTS: A total of 65 vessel-tumor interface areas of 55 patients were analyzed. Almost all mediastinal and hilar vascular structures including pulmonary arteries and veins, aorta, superior vena cava and its branches, and left atrium with pulmonary veno-atrial junctions could be easily assessed by convex probe endobronchial ultrasound. The intra-agreement of both modalities in detecting vascular invasion was k=0.268 (p=0.028). In nine patients with a surgical confirmation, the sensitivity, specificity, positive and negative predictive values, and accuracy values were 100%, 33.3%, 75.0%, 100%, and 77.7%, respectively for convex probe endobronchial ultrasound and 66.6%, 33.3%, 66.6%, 33.3%, and 55.5%, respectively for computed tomography. CONCLUSION: Convex probe endobronchial ultrasound can be used to detect vascular invasion alone or in conjunction with contrast-enhanced computed tomography. Hence, a T4 lesion would be better differentiated from T3 in clinical staging of lung cancer.

Predictors of mortality in cancer patients who need intensive care unit support: a two center cohort study

Background/aim: Cancer patients frequently need intensive care support due to respiratory failure. We aimed to evaluate the predictors of mortality in cancer patients who were admitted to the intensive care unit (ICU). Materials and methods: This study was performed in the ICUs of two centers between 1 January 2008 and 31 December 2015. Demographic data, cancer type, causes of respiratory failure, comorbidities, APACHE II scores, treatments, and mortality rates were recorded. Results: A total number of 583 cancer patients (477 males) were enrolled from the two centers. Of those, 472 patients had lung cancer (81%), while 111 had extrapulmonary malignancies (19%), having similar mortality rates. Causes of respiratory failure were mostly invasion of the cancer itself in 84% of cases and due to infection in 12%. ICU mortality rate was 53% and the 1-year mortality rate was 80%. APACHE II scores were significantly higher in nonsurvivors (P < 0.001). One-year survival was found to be significantly shorter in females than males (9 days vs. 12 days) in patients with lung cancer. Conclusion: Mortality rates of cancer patients who need ICU support are higher than overall ICU mortality. High APACHE II scores and female sex seem to be related to mortality in these patients.

Assessment of osteoporosis using the FRAX method and the importance of vitamin D levels in COPD patients.

BACKGROUND: The aim of this paper was to evaluate the availability of FRAX for assessing osteoporosis risk, and to demonstrate the importance of vitamin D levels in COPD patients. METHODS: Fourty-six males who fulfilled the COPD diagnostic criteria defined by GOLD were included. Age, race, BMI, physical activity frequency, smoking and dietary habits, age at COPD diagnosis, disease duration, fractures history, and medications use were determined. Levels of 25(OH)D were detected. BMD was measured by DXA at lumbar spine, femoral neck, and entire femur, and classified according to ISCD. FRAX score was calculated. Control group was composed of 40 non-smoker individuals without previous history of pulmonary diseases. RESULTS: 25(OH)D levels were significantly different between patients and controls. In the COPD group, a statistically significant difference in vitamin D levels was detected among the A, B, C, and D grades, while no such significant differences in FRAX scores were detected. 25(OH)D levels were significantly low in COPD patients with disease exacerbations and hospitalizations in the previous one year. No correlation was detected between vitamin D levels and the FRAX score. A positive correlation was observed between vitamin D levels and T-score. FRAX scores were higher and vitamin D levels were lower in osteoporotic COPD patients than in non-osteoporotic COPD patients. CONCLUSION: Using FRAX for assessing osteoporosis in COPD can reduce fracture risk and allow adequate treatment. Since vitamin D levels are related to exacerbations and hospitalizations, vitamin D supplementation may be needed in COPD patients, especially in those with high FRAX scores.

The Contribution of Ultrasonographic Characteristics of Mediastinal Lymph Nodes on Differential Diagnosis of Tuberculous Lymphadenitis from Sarcoidosis.

BACKGROUND: Sarcoidosis and Mediastinal Tuberculous Lymphadenitis (MTLA) are two granulomatous diseases. Differentiation between these two diseases is dependent on clinical presentation, microbiological investigation, and cytopathological examination. In endemic regions, differential diagnosis of MTLA and sarcoidosis might be difficult. Endobronchial ultrasound guided Transbronchial Needle Aspiration (EBUS-TBNA) is a new diagnostic procedure for the diagnosis of mediastinal lymphadenopathy. EBUS not only enables the sampling of Lymph Nodes (LN), but also visualization of sonographic features of them. We hypothesized that the sonographic features of LN may help to differentiate MTLA from sarcoidosis. MATERIALS AND METHODS: This is a retrospective analysis of patients with intrathoracic lymphadenopathy who underwent EBUS-TBNA and were finally diagnosed as sarcoidosis or MTLA. Size, shape, margin, echogenicity, and coagulation necrosis were compared between the groups. RESULTS: A total of 257 LNs (215 sarcoidosis, 42 MTLA) were examined in 101 patients. A heterogeneous echotexture of lymph nodes was significantly more common (P <0.0001) in MTLA (69%) than sarcoidosis (36.2%). Also, necrosis was statistically significantly higher in MTLA compared to sarcoidosis (P<0.0001). The vascular pattern was similar in both groups (P=0.9050). Nearly half of the patients had grade 1 vascular pattern in both groups. The odds for diagnosis of MTLA were significantly higher in the presence of heterogeneous echotexture (odds ratio [OR], 7,00) or necrosis sign (OR, 131,2). CONCLUSION: Vascular patterns of two diseases were similar. Heterogeneous echotexture and necrosis sign in the LNs on EBUS are specific for MTLA. Combination of these findings with a positive tuberculin skin test, favors the diagnosis of MTLA over sarcoidosis.

Use of adjuvant chemotherapy for nonsmall cell lung cancer: Is advanced age a prognostic factor?

PURPOSE: In patients with nonsmall cell lung cancer (NSCLC), the effect of age on adjuvant chemotherapy (CT) after primary surgical treatment is controversial. The aim of this study was to investigate the effect of age and other clinical variables on survival in NSCLC patients who received adjuvant CT. MATERIALS AND METHODS: NSCLC patients who underwent primary resection and received adjuvant CT between January 2012 and January 2016 were included in the study. The patients were divided into two age groups: (1) patients >65 years old (older patient group) and (2) patients ≤ 65 years old (young patient group). The effects of clinical variables such as age, histology, pT stage, pN stage, pTNM stage, adjuvant thoracic radiotherapy, and recurrence status on survival were assessed using the log-rank test and multivariable Cox regression analysis. RESULTS: A total of 91 NSCLC patients who received adjuvant CT after complete resection were included in the study. The median age of the patients was 60 (36-73) years. Eighty-six percent of the patients were male. 49.4% had squamous NSCLC and 50.6% had nonsquamous NSCLC. 59% had stage I and II disease and 41% had stage III disease. The mean overall survival was 61.9 months [95% confidence interval (CI) 51.28-72.69] in the young patient group and 73.1 months (95% CI 60.24-85.94) in the older patient group . The mean disease-free survival was 47.0 months (95% CI 37.81-56.23) in the young patient group and 51.1 months (95% CI 40.68-57.17) in the older patient group (P = 0.119 and P = 0.407, respectively). Pathological stage III [heart rate (HR): 2.615, P = 0.014] and presence of recurrence (HR: 2.496, P = 0.019) were found to be independent risk factors. However, age did not show statistical significance (HR: 0.428, 95% CI 0.128-1.427, P = 0.167). CONCLUSION: In NSCLC patients who underwent complete resection and received adjuvant CT, advanced age had no prognostic effect on survival.

Sex-related differences in COPD Assessment Test scores of COPD populationswith or without significant anxiety and/or depression.

BACKGROUND/AIM: Sex-related differences have not been thoroughly explored in chronic obstructive pulmonary disease (COPD). We aimed to evaluate possible sex-related differences in COPD Assessment Test (CAT) scores of COPD patients with or without significant anxiety and/or depression. MATERIALS AND METHODS: Stable COPD patients were prospectively enrolled in the study between July 2013 and April 2014. Levels of anxiety, depression, dyspnea, and health-related quality of life parameters were assessed using specific questionnaires, including the CAT and others. Demographic and clinical data were recorded and physiological tests were performed. All the data were compared to determine any sex-related differences. RESULTS: A total of 128 COPD patients (86 men, 42 women, mean age: 60.5 ± 9.3 years) were included. The women were significantly younger and had lower pack-years of cigarette smoking, and higher biomass smoke exposure, but displayed similarly severe COPD as compared to men. Beck anxiety (13.5-11) and Beck depression (15-11) inventory results were significantly higher in women than men (P = 0.04, P = 0.01). No statistically significant difference was found between the sexes in terms of CAT score, Modified Medical Research Council score, or COPD stage parameters (P > 0.05). CONCLUSION: Female patients have higher levels of depression and anxiety scores but present the same CAT scores related to COPD severity as compared to men.
