To evaluate the utility of neutrophil–lymphocyte ratio (NLR) determined at initial diagnosis in predicting advanced disease stage and discriminating between active and stable disease in sarcoidosis. A total of 465 patients with biopsy-proven sarcoidosis (age: 47 years, 70.5% females) were included in this retrospective cross-sectional study. Data on patient demographics, sarcoidosis stage, clinical status (stable and active), anti-inflammatory treatments, complete blood count, and inflammatory markers including erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), neutrophil-to-lymphocyte ratio (NLR) and platelet/mean platelet volume (MPV) ratio were recorded. NLR values were compared by subgrouping the patients according to the stage of sarcoidosis and clinical status, while the receiver operating characteristics (ROC) curve was plotted to determine the role of NLR in the identification of disease activity with the calculation of area under the curve (AUC) and cutoff value via ROC analysis. Overall, active, and stable disease was evident in 36 (7.8%) and 427 (92.2%) patients, respectively. Median NLR values were significantly higher in patients with active disease compared with stable disease (3.31 (2.34–4.31) vs. 2.29 (1.67–3.23), p = 0.005). Advanced sarcoidosis stage was associated with significantly higher NLR values at stages 0, I, II, III and IV, respectively (p = 0.001). ROC analysis revealed an NLR cutoff value of ≥2.39 (AUC (95% CI): 0.70 (0.62–0.79), p < 0.001) to discriminate between active and stable clinic with a sensitivity of 72.0% and specificity of 52.0%. The significantly higher percentage of patients with active vs. stable disease had NLR values ≥2.39 (74.0 vs. 47.0%, p = 0.002). Our findings indicate the potential utility of on-admission NLR values to predict the risk of advanced disease stage and to discriminate between active and stable disease in sarcoidosis. Measured via a simple, readily available, and low-cost test, NLR seems to be a valuable marker for monitoring disease activity and progression.

BACKGROUND: Coronavirus disease 2019 (COVID-19) continues to cause major mortality and morbidity worldwide even after a year of its emergence. In its early days, hypertension, diabetes, and cardiovascular diseases were noted as poor prognostic factors, while obesity gained attention at a later stage. In the present study, unfavorable clinical outcomes (transfer to the intensive care unit, invasive mechanical ventilation, and mortality) were investigated in obese patients with COVID-19. MATERIALS AND METHODS: In this retrospective study we analyzed patients with positive polymerase chain reaction test in tertiary care hospital between March-May 2020. They were divided into 3 groups according to body mass index (BMI) as normal, overweight, and obese (BMI: 18.5 - 24.99 kg/m², 25 - 29.99 kg/m², and ≥ 30 kg/m², respectively). We compared clinical features and laboratory findings of these groups and recorded adverse clinical outcomes. Multivariate logistic analysis was performed for unfavorable outcomes. RESULTS: There were 99 patients (35%), 116 (41%), and 69 patients (24%) in the normal-weight, overweight, and obese group, respectively. Among all patients, 52 (18%) patients were transferred to the intensive care unit (ICU), 30 (11%) patients received invasive mechanical ventilation (IMV), and 22 patients (8%) died. Obese patients had minimum 1 more comorbidity than normal BMI patients (73% vs. 50%, P = 0.002), and a longer median (interquartile range [IQR]) duration of hospitalization (8 [5 - 12] vs. 6 [5 - 9]) days, P = 0.006). Obese participants had higher concentrations of serum C-reactive protein, procalcitonin, ferritin than non-obese patients (P

Background/aim: 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. Materials and 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% (

This study was designed to evaluate the influence of gender on the inhaler technique of subjects on inhaler therapy and to determine the factors predicting the correct inhaler technique and a change of inhaler device. METHODS: A total of 568 adult subjects (276 male, 292 female) on inhaler therapy were included in this cross-sectional, observational study. Data on sociodemographic characteristics, inhaler therapy, subject-reported difficulties, and technician-reported errors in inhaler technique were recorded. RESULTS: A change of inhaler device was noted in 71.0\% of male subjects and 77.4\% of female subjects, and this was based on the physicians' decision in most cases (41.7\% and 51.7\%, respectively). A higher percentage of female subjects reported difficulties with using inhalers (63.7\% vs 40.6\%, P < .001). Overall, having received training on the inhaler technique was associated with a higher likelihood of correct inhaler technique (odds ratio 12.56, 95\% CI 4.44-35.50, P < .001) and a lower risk of device change (odds ratio 0.46, 95\% CI 0.27-0.77, P = .004). CONCLUSIONS: Errors in the inhaler technique, including inhalation maneuvers and device handling, were common in subjects on inhaler therapy. Subject-reported difficulties with using inhalers were more prevalent among female subjects, whereas errors in the inhaler technique identified by direct observation were similarly high in both genders. Overall, a lack of training on the inhaler technique predicted a higher likelihood of errors in the inhaler technique and a change of inhaler device.

Investigations of muscle dysfunction in patients with idiopathic pulmonary fibrosis (IPF) are limited to peripheral muscles. However, decreased thoracic muscle mass is known and deterioration of chest wall muscle strength is not clear.The aims of the present study were to evaluate pectoralis muscle strength located on the chest wall and to investigate the relationship of spirometric measurements and respiratory muscle strength with pectoralis muscle strength.Elderly patient with IPF (mean disease duration 7.47±7.04 years) and the age-and sex-matched healthy volunteers were recruited in this cross-sectional study. The pulmonary function test was performed by a portable spirometer for spirometric variables and a gas analyzer for diffusing capacity for carbon monoxide (DLA total of 17 patients with IPF (9 males, mean age 69.06±3.94 years) and 19 healthy controls (10 males, mean age 70.95 ±4.99 years) were included. Patients with IPF had lower pectoralis muscle strength than healthy controls (p0.001). Significant relationships were found between pectoralis muscle strength and MIP (r=0.79, p0.001), MEP (r=0.81, p0.001), FEVIn patients with IPF, pectoralis muscle strength decreases and is associated with pulmonary function. In particular pectoralis muscle strength is likely to have an important impact on FVC%. Therefore, we consider that this test should be included routinely in chest diseases and rehabilitation clinics. The trial was registered U.S. National Library of Medicine clinical trial registry (https://clinicaltrials.gov, Trial ID: NCT04803617).

The choice of treatment according to the inflammation type in acute exacerbation of chronic obstructive pulmonary disease (AECOPD) has been of recent interest. This study investigated the role of novel biomarkers, hospital outcomes, and readmission rates in the first month in patients with eosinophilic or neutrophilic AECOPD.We conducted a retrospective observational cohort study in a Chest Teaching Hospital with hospitalized AECOPD patients. Subjects' characteristics, hemogram results, C-reactive protein (CRP), neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), platelet/mean platelet volume (PLT/MPV), length of hospital stay, mortality, and steroid use were recorded. Eosinophilic AECOPD defined as peripheral blood eosinophilia (PBE) was2% and neutrophilic AECOPD as PBE ≤2%. Readmission within 28 days of discharge was recorded.Of 2727(31.5% females) patients, eosinophilic AECOPD was found in 510 (18.7%) patients. Leucocytes, CRP, NLR, and PLR were significantly higher in neutrophilic AECOPD than in eosinophilic AECOPD (p0.001). Steroid use and mortality rate were 45% and 0.6% in eosinophilic AECOPD and 71%, and 1.4% in neutrophilic AECOPD, respectively (p=0.001, p=0.19). Age75 years, albumin2.5 g/dL, CRP50 mg/dL, and PLT/MPV20×103 were found to be risks factors for hospital mortality (p0.05 each). Readmission rates within 28 days of discharge were 5% (n=136), and this rate was higher in eosinophilic AECOPD patients not taking steroids (p0.001).NLR, PLR, and CRP levels were higher in neutrophilic AECOPD compared with eosinophilic AECOPD. These markers decreased with treatment in neutrophilic AECOPD. A PLT/MPV ratio of20×103 resulted in an increased mortality rate. Thus, appropriate steroid therapy may reduce readmission rates in the first 28 days after discharge in eosinophilic AECOPD.

Data on patient demographics (age and gender), inflammatory markers, including neutrophil-to-lymphocyte ratio, C-reactive protein, platelet/mean platelet volume ratio, arterial blood gas analysis, and pulmonary function test findings, including forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), and FEV1/FVC were obtained from medical records.Results: Carbon dioxide partial pressure levels were significantly higher in the biomass smoke exposure than in the cigarette smoke exposure group (mean [SD] 51.0 [8.0] vs 47.0 [8.0] mmHg, p=0.026, respectively). Spirometry revealed similarly low levels for FEV1 (%) (38.0 [16.0] vs 40.0 [12.0]%) and FVC (%) (45.0 [19.0] vs 39.0 [19.0]%) in cigarette-smoke and biomass smoke exposure groups, whereas biomass smoke exposure was associated with significantly higher FEV1/FVC (75.0 [14.0] vs 58.0 [12.0]%, p=0.001), lower FVC (mL) (mean [SD] 744.0 [410.0] vs 1,063.0 [592.0] mL, p=0.035) and lower percentage of patients with FEV1/FVC 70% and more prominent loss of vital capacity than cigarette smoke exposure seems to indicate the likelihood of at least 18 years of biomass exposure to be sufficiently high to be responsible for both obstructive and restrictive pulmonary diseases. Keywords: biomass exposure, cigarette smoke, inflammatory markers, spirometry, chronic respiratory failure

Introduction We aimed to assess the relationship between peripheral eosinophilia and neutrophil/lymphocyte ratio with hospital admissions and re-admissions with chronic obstructive pulmonary disease (COPD) exacerbations. Materials and methods An observational cohort study was carried out in a tertiary teaching hospital. Subjects with previously diagnosed COPD and who were admitted as outpatients with acute exacerbations were included. The subjects' characteristics, complete blood count (CBC) parameters, neutrophil to lymphocyte rate (NLR), C-reactive protein (CRP), mean platelet volume (MPV) on admission and re-admission within the first 28 days. Patients were grouped according to their peripheral blood eosinophilia levels; group 1, > 2% (eosinophilic), group 2, ≤ 2% (non-eosinophilic or neutrophilic). The recorded data from the two groups were compared. Result 1490 eligible COPD subjects were enrolled. Approximately 42% were classified as eosinophilic. The non-eosinophilic group had a significantly higher leukocyte count, neutrophil percentage, and NLR than the eosinophilic group. The NLR value in patients with repeat re-admissions was higher than the average, i.e., 4.50 (p= 0.001). MPV and CRP measured on admission and re-admission were similar in both groups. The rate of hospital re-admission within 28 days was significantly higher in patients with a non-eosinophilic attack. Conclusions When a patient is admitted to outpatients with a NLR greater than 4.50 and with a non-eosinophilic exacerbation they have an increased risk of re-admission in the first month. Higher NLR values and non-eosinophilic exacerbations may be helpful for the early detection of potential acute attacks in COPD patients, and may be indicators for antibiotic management.

Introduction Tuberculosis drug resistance can be assessed by physicians with different approaches on issues such as the choice of treatment protocol and duration of treatment. Materials and methods In this study, we aimed to evaluate the treatment regimens and treatment results of patients with non multi-drug resistant tuberculosis (MDR-TB) drug resistance implemented in different chest disease clinics in our hospital. The 167 culture-positive patients with nonMDR-TB drug resistance diagnosed between 2008-2010 were analyzed retrospectively. Patients' age, gender, previous TB treatments, bacteriological cruise, drug resistance patterns and treatment outcomes were analyzed. Result One hundred sixty-seven patients with eligible data were evaluated; there were 117 (70.1%) men and 50 (29.9%) women, mean age was 42.35 (18-90) years, respectively. Among mono drug resistance; H resistance in 75 (44.9%) patients and R resistance in 11 patients was detected. In 19 (11.4%) patients HS resistance was detected as multiple drug resistance. One hudred and twenty-five (74.9%) were new cases. When treatment the results of in all patients evaluated, 136 (81.4%) of the patients achieved treatment success. Sixty-four (51.2%) of the new TB cases treated with "standard treatment protocols for new cases" (2HRZE/4H) and 51 (40.8%) of them treated with "other treatment protocols". Ten (23.8%)of the recurrent TB cases" standard treatment for recurrent cases (2HRZES/HRZE/5HRE) and 9 (21.4%) 33 (19.8%) of them treated with other protocols. The combination of the rthe treatment protocol and descriptive information about the duration of the treatment could not be created as 33 (19.8%) of the cases left without completing their treatment. Conclusions As a result of the analysis, patients have completed their treatment, there was no significant difference in treatment outcomes. Patients with Non MDR-TB drug resistance should be monitored well and should be careful in terms of MDR-TB.

Akgun, Metin/0000-0003-3404-4274 WOS: 000506838600006 PubMed: 31584386 OBJECTIVES: It is considered that occupational exposure accounts for up to 25% of all cases of adult asthma. We need detailed individual-level data regarding the relationship between asthma, occupation, and work-related symptoms in Turkey to inform policies on workplace safety. This study aimed to investigate the association between asthma symptoms, occupation type, and workplace exposure in patients with asthma. MATERIALS AND METHODS: In this cross-sectional multicenter study, adult patients with asthma were investigated by a questionnaire in terms of relationship between asthma symptoms and workplace exposure. The study population was adult patients who had been diagnosed with asthma for at least six months prior to study and who were under follow-up in Ankara, Istanbul, Erzurum, Duzce, Trabzon, Denizli, and Diyarbakir. RESULTS: The mean age of the 345 cases (188 females) was 41 +/- 13 years. The majority of the patients (36.8%) were "housewives"; other common occupations were office workers (6.7%), textile workers (4%), students (3.8%), hospital staff (3.5%), and cleaners (2.9%). Thirty-five percent of patients described worsening of asthma during working periods. Among patients with a history of increased symptoms in workplace, 100 (83%) developed asthma after starting work, while 20 patients (17%) had pre-existing asthma. Half of the patients described workplace exposure to dust, fume, and gases. Exposure to cleaning supplies at home was present in 43% of the subjects. Of all housewives, 12% (n=15) described an increase in their asthma symptoms during housework. The frequency of bleach or hydrochloric acid use alone among housewives was 60% and 34%, which was significantly higher than other occupations. The FEV1/FVC ratio of housewives who frequently used hydrochloric acid (FEV1/FVC=71.5) was lower than that of non-users (FEV1/FVC=74.9) (p=0.024). CONCLUSION: Patients with asthma experience significant workplace exposures that exacerbate their symptoms. Housewives experience significant exposure that triggers allergic and asthma symptoms. It is important to raise awareness about the prevalence and risks of occupational (including in-home) exposures in asthmatics patients and physicians to minimize asthma triggers and exacerbations.

We aimed to assess any differences in these novel inflammatory markers according to exacerbation severity in patients with COPD in both eosinophilic and neutrophilic endotypes. Method: This retrospective cross-sectional study was conducted at a tertiary education hospital. Previously diagnosed COPD patients admitted to the hospital with acute COPD exacerbation (AECOPD) were enrolled into the study. Patients were grouped according to COPD endotype, eosinophilic (peripheral blood eosinophil rate ≥2%) and neutrophilic (peripheral blood eosinophil rate

OBJECTIVES Chronic respiratory diseases exert a global health burden with high health care costs, morbidity, and mortality. The aim of the present study was to investigate the effect of pulmonary rehabilitation (PR) on emergency admission and hospitalization rates of patients with chronic respiratory disease. MATERIALS AND METHODS In this retrospective cohort study, hospitalization rates and emergency admissions of patients before (December 2014-December 2015) and after PR (January 2015-December 2016) were investigated. Patients with chronic respiratory diseases were included. Chronic obstructive pulmonary disease (COPD) patients were classified based on the Global Initiative Chronic Obstructive Pulmonary Disease assessment scheme. PR was applied by three physiotherapists over 8 weeks (2 days/week). Data on patient demographics, clinical and anthropometric data, spirometry, exercise capacity, and quality of life before and after PR were acquired. RESULTS This study evaluated 51 patients, of whom 76% were men. A total of 37 (73%) COPD patients and 14 (27%) non-COPD patients (7 bronchiectasis, 4 interstitial lung disease, and 3 kyphoscoliosis) were included. The patients exhibited significantly improved incremental shuttle walk test (ISWT) and endurance test scores (p

Background: Although right ventricular (RV) dysfunction in pulmonary diseases has been associated with increased morbidity, tools for RV dysfunction identification are not well defined. Objective: The aim of this study was to evaluate the magnitude of RV dysfunction by means of speckle tracking echocardiography (STE) in patients with chronic obstructive pulmonary disease (COPD) and to investigate whether STE could be used as an index of RV improvement after a pulmonary rehabilitation (PR) program. Methods: Forty-six patients with COPD undergoing PR program and 32 age-sex matched healthy subjects were enrolled. RV function was evaluated at admission and after PR program by conventional two-dimensional echocardiography (2DE) and STE. In addition, exercise tolerance of subjects was evaluated using the six-minute walk test (6MWT). Results: COPD patients had worse RV function according to STE and 2DE as well. STE was more sensitive than conventional 2DE in determining RV improvement after PR program - RV global longitudinal strain (LS): 20.4 ± 2.4% vs. 21.9 ± 2.9% p < 0.001 and RV free wall LS: 18.1 ± 3.4% vs. 22.9 ± 3.7%, p < 0.001). RV free wall LS was directly related to distance walked at baseline 6MWT (r = 0.58, p < 0.001) and to the change in the 6MWT distance (6MWTD ∆) (r = 0.41, p = 0.04). Conclusions: We conclude that STE might be as effective as 2DE for evaluation of global and regional RV functions. STE may become an important tool for assessment and follow-up of COPD patients undergoing PR program to determine the relationship between RV function and exercise tolerance. Resumo Fundamento: Embora a disfunção do ventrículo direito (VD) nas doenças pulmonares tenha sido associada ao aumento da morbidade, as ferramentas para a identificação da disfunção do VD não estão bem definidas. Objetivo: O objetivo deste estudo foi avaliar a disfunção do VD por ecocardiografia speckle tracking (STE) em pacientes com doença pulmonar obstrutiva crônica (DPOC), e se a STE pode ser usada como indicador de melhora da função ventricular direita após um programa de reabilitação pulmonar (RP). Métodos: Quarenta e seis pacientes com DPOC submetidos ao programa de RP e 32 controles sadios pareados por sexo e idade foram incluídos no estudo. A função do VD foi avaliada na admissão e após o programa de RP por ecocardiografia bidimensional convencional e por STE. Além disso, a tolerância ao exercício foi avaliada pelo teste de caminhada de seis minutos (TC6M). Resultados: Pacientes com DPOC apresentaram pior função do VD segundo STE e ecocardiografia bidimensional convencional. Em comparação ao método convencional, a STE mostrou maior sensibilidade em determinar melhora da função ventricular direita após o programa de RP - strain longitudinal (SL) global do VD: 20,4 ± 2,4% vs. 21,9 ± 2,9% p < 0,001; SL da parede livre do VD: 18,1 ± 3,4% vs. 22,9 ± 3,7%, p < 0,001. O SL da parede livre do VD relacionou-se diretamente com a distância percorrida no TC6M basal (r = 0,58, p < 0,001) e com a variação no TC6M ∆ (TC6M) (r = 0,41, p = 0,04). Conclusões: Concluímos que a STE pode ser tão eficaz como a ecocardiografia bidimensional convencional na avaliação das funções globais e regionais do VD. Ainda, a STE pode se tornar uma importante ferramenta de avaliação e acompanhamento de pacientes com DPOC submetidos à RP para determinar a relação entre função ventricular direita e tolerância ao exercício.

WOS: 000435396300006 PubMed: 30020040 Introduction: Welding produces miscellaneous gases and particles that has various impact on respiratory system and long term exposure may result "welders'lung". The aim of this study is to describe the radiological findings of welders' and make an awereness for welders radilogical findings. Materials and Methods: The clinical and radiological findings of welders' who had hospital applications with respiratory symptoms between January 2010-January 2017 were evaluated retrospectively. Results: A total of 16 male welders with mean age 37 +/- 8 years had the mean duration of welding occupation 12 +/- 7 years. The most common symptoms were coughing (87%), sputum production (63%) and dyspnoea (63%). Thirteen welders were working in shipyards and 3 in construction business and other workplaces. Three (19%) patients had rhonchi on physical examination and these patients had decreased FEV1/FVC values below 70% on spirometry. Poorly-defined centrilobular micronodules that were not clearly visible on chest radiographs observed on thorax high resolution computed tomography. Bronchoscopy was performed to 7 patients. Iron-positive pigment granules and ferruginous bodies were revealed in 3 patients' bronchoalveolar lavage. Conclusion: Welders' chest X-ray deserve a closer look. In pulmonary radiology, there may be radiographical findings ranging from small ill defined nodules to groundglass opacites. Physcians should look more careful to welders' chest X-ray and incase of suspicious findings best can be detected on high HRCT. An awareness for the radiological findings will also reduce interventional procedures in these patients hereby, occupational history must be included in daily practice of physicians.

OBJECTIVE: Physicians do not adequately use their unique professional privilege to prevent patients from smoking. The aim of this study was to investigate the type and extent of advice given to patients by physicians of different medical specialties regarding smoking cessation. METHODS: In total, 317 volunteer physicians were included in this study. The participants rated their attitudes toward the smoking habits of their patients by completing a questionnaire. The approaches used to address the smoking habits of patients significantly differed among physicians working at polyclinics, clinics and emergency service departments (p

The rapid detection of the reasons for mining accidents that lead to emergency situations is vital for search and rescue work. The control of fire and gas leakage provides an immediate approach for rescue works for deaths or injuries and the detection of who needs resuscitation outside of the mine. The evacuation and recovery operations should be directed by continuous monitoring of the mine environment due to fire and explosion risks. The main toxic gases in mines are carbon monoxide (CO) and carbon dioxide (CO2); the flammable gases are methane (CH4), CO, and hydrogen (H2); the suffocating gases are CO2, nitrogen (N20), and CH4; and the toxic gases are CO, nitrogen oxides (NOx), and hydrogen sulfide (H2S).

Patients and methods: A total of 509 adult patients with COPD (n=328) or asthma (n=181) who were currently using an inhaler device were included in this study. Data on patient demographics, duration of disease, type and duration of inhaler therapy, and assessment of inhaler technique were recorded. Results: Metered dose inhaler (MDI) was the most common type of inhaler used by a similarly high percentage of patients in both COPD (83.2%) and asthma (77.3%) groups. Failure to exhale before inhaling through device (75.8% and 68.5% for MDIs; 73.2% and 71.8% for Aerolizer®/Handihaler®; 53.1% and 66.7% for Turbuhaler®) was the most common error in inhaler technique, in both COPD and asthma groups. Device-specific errors in inhaler techniques were more common in asthma patients as compared with COPD patients, particularly for MDIs (P-values ranged from 0.046 to 0.0005), as associated with female gender (failure to press the buttons on both sides of Aerolizer®/Handihaler®, P=0.006), shorter duration of disease (failure to hold MDI or head in a vertical position, P

Anah tar soz cuk ler: Beta-2 transferrin; dura-plevral fistul; transudatif efuzyon. Twenty three-year-old man had thoracal spinal cord surgery for gunshot injury three months ago. He had right hemiplegia and paraplegia for the past two months. He was admitted with poor performance status and progressive, severe dyspnea. Chest X-ray showed massive pleural effusion on the right side. Thoracentesis showed transudative pleural fluid. Duropleural fistula was considered due to the history of spinal injury and surgery. The presence of cerebrospinal fluid in the pleural fluid was demonstrated by beta-2 transferrin test. After the demonstration of the presence of duropleural fistula on intrathecal contrast-enhanced computed tomography scan surgical management of the duropleural fistula was successfully repaired by duroplasty. This case was presented as a complication of spinal cord injury and neurosurgery duropleural fistula is a very rare reason of massive transudative pleural effusions and the use of the cerebrospinal fluid by beta-2 transferrin in pleural effusion is reported very rare in the literature.

The results of arterial blood gas (ABG) analyses and spirometry, and 6MWD measurements with 12-month interval were recorded from the patient files, in addition to demographics, comorbidities, and body mass indices. The groups were compared in terms of 6MWD via analysis of variance (ANOVA) and multiple linear regression (MLR) analysis (independent variables: analysis age, sex, baseline 6MWD, baseline forced expiratory volume in 1 second, and baseline partial carbon dioxide pressure, in reference to COPD group).Results: A total of 105 patients with a mean age (± standard deviation) of 61±12 years of whom 37 had COPD, 34 had OHS, 20 had KS, and 14 had DPLD were included in statistical analysis. There were no significant differences between groups in the baseline and delta values of ABG and spirometry findings. Both univariate ANOVA and MLR showed that the OHS group had the lowest baseline 6MWD and the highest decrease in 1 year (linear regression coefficient -24.48; 95% CI -48.74 to -0.21, P=0.048); while the KS group had the best baseline values and the biggest improvement under home NIMV (linear regression coefficient 26.94; 95% CI -3.79 to 57.66, P=0.085).Conclusion: The 6MWD measurements revealed improvement in exercise capacity test in CHRF patients receiving home NIMV treatment on long-term depends on etiological diagnoses.

Mining is a very hard and risky sector that includes domino effect risks in any adverse event and requires knowledge, experience, proficiency and continuous auditing, and it is very hard and risky. Turkey has not signed International Labour Organization (ILO) contract number 176 yet{*}. This contract is named the 1995 Safety and Health in Mines Convention, and the safe and healthy working conditions are set, and obligations are listed. The most important mistakes are made because these national and international rules and regulations are not carried out. In this chapter, these mistakes are elaborated, and suggestions are made.

Acute respiratory failure (ARF) can necessitate mechanical ventilation and intensive care unit (ICU) admission in patients with COPD. We evaluated the reasons COPD patients are admitted to the ICU and assessed long-term outcomes in a retrospective cohort study in a respiratory level-III ICU of a teaching government hospital between November 2007 and April 2012. All COPD patients admitted to ICU for the first time were enrolled and followed for 12 months. Patient characteristics, body mass index (BMI), long-term oxygen therapy (LTOT), non-invasive ventilation (LT-NIV) at home, COPD co-morbidities, reasons for ICU admission, ICU data, length of stay, prescription of new LTOT and LT-NIV, and ICU mortality were recorded. Patient survival after ICU discharge was evaluated by Kaplan-Meier survival analysis. A total of 962 (710 male) patients were included. The mean age was 70 (SD 10). The major reasons for ICU admission were COPD exacerbation (66.7%) and pneumonia (19.7%). ICU and hospital mortality were 11.4%, 12.5% respectively, and 842 patients were followed-up. The new LT-NIV prescription rate was 15.8%. The 6-month 1, 2, 3, and 5-year mortality rates were 24.5%, 33.7%, 46.9%, 58.9% and 72.5%, respectively. Long-term survival was negatively affected by arrhythmia (p < 0.013) and pneumonia (p < 0.025). LT-NIV use (p < 0.016) with LTOT (p < 0.038) increase survival. Pulmonary infection can be a major reason for ICU admission and determining outcome after ICU discharge. Unlike arrhythmia and pneumonia, LT-NIV can improve long-term survival in eligible COPD patients.

Although most COPD exacerbations are neutrophilic, approximately 10%–25% of exacerbations are eosinophilic.Aim: We aimed to evaluate mortality and outcomes of eosinophilic and non-eosinophilic COPD exacerbations and identify new biomarkers that predict survival.Methods: A retrospective observational cohort study was carried out in a tertiary teaching hospital from January 1, 2014 to November 1, 2014. All COPD patients hospitalized with exacerbations were enrolled in the study at their initial hospitalization and followed-up for 6months after discharge. Electronic data were collected from the hospital database. Subjects’ characteristics, hemogram parameters, CRP levels, neutrophil-to-lymphocyte ratio (NLR), platelet-to-mean platelet volume ratio on admission and discharge, length of hospital stay (days), readmissions, and mortality were recorded. Patients were grouped according to peripheral blood eosinophil (PBE) levels: Group 1, >2% PBE, eosinophilic; Group 2, non-eosinophilic ≤2%. Patient survival after hospital discharge was evaluated by Kaplan–Meier survival analysis.Results: A total of 1,704 patients hospitalized with COPD exacerbation were included. Approximately 20% were classified as eosinophilic. Six-month mortality was similar in eosinophilic and non-eosinophilic groups (14.2% and 15.2%, respectively); however, the hospital stay length and readmission rate were longer and higher in the non-eosinophilic group (P
