Abstract
Objectives The authors aimed to evaluate the characteristics and management outcomes of patients who developed tracheal stenosis after invasive mechanical ventilation (IMV) due to COVID-19. Design, Setting, and Participants The data of 7 patients with tracheal stenosis and 201 patients without tracheal stenosis after IMV due to COVID-19 between March 2020 and October 2021 were retrospectively analyzed. Interventions Flexible bronchoscopy was performed for the diagnosis of tracheal stenosis and the evaluation of the treatment's effectiveness, and rigid bronchoscopy was applied for the dilatation of tracheal stenosis. Measurements and Main Results In the follow-up period, tracheal stenosis was observed in 7 of 208 patients (2 women, 5 men; 3.3%). The patients were divided into 2 groups as patients with tracheal stenosis (n = 7) and patients without tracheal stenosis (n = 201). There were no statistically significant differences between the 2 groups in terms of age, sex, body mass index, and comorbidities (p > 0.05). The mean duration of IMV of the patients with tracheal stenosis was longer than patients without tracheal stenosis (27.9 ± 13 v 11.2 ± 9 days, p < 0.0001, respectively). Three (43%) of the stenoses were web-like and 4 (57%) of them were complex-type stenosis. The mean length of the stenoses was 1.81 ± 0.82 cm. Three of the patients were treated successfully with bronchoscopic dilatation, and 4 of them were treated with tracheal resection. Conclusions Tracheal stenosis developed in 7 of 208 (3.3%) patients with COVID-19 who were treated with IMV. The most important characteristic of patients with tracheal stenosis was prolonged IMV support.

Abstract
Background Currently there is no proven medical treatment for COVID-19. We aimed to determine the factors affecting mortality and changes in clinical and laboratory findings in patients with severe COVID-19 pneumonia treated with lopinavir/ritonavir (Lpv/r). Methods Data of survivor and non-survivor severe COVID-19 pneumonia patients treated with Lpv/r were analysed retrospectively. Results A total of 73 patients, 26 (35.6%) females and 47 (64.4%) males were included in the study. The mean age of non-survivor and survivor patients was 64.3 ± 12 and 52.6 ± 12.2, respectively (p < 0.0001). Frequency of smoking and comorbid diseases was higher in non-survivor patients than in survivor patients (37% vs. 8.7% p = 0.003 and 92.6% vs. 28.3%, p < 0.0001, respectively). Age (Odds ratio [OR] 1.09, 95% confidence interval [95% CI] 1.03–1.14), smoking (OR 6.18, 1.7–22.42), presence of comorbid disease (OR 31.73, 6.26–153.56), coronary artery disease (OR 9.26, 1.79–47.77), arrhythmia (OR 13.8, 1.56–122.22), hypertension (OR 14, 4.28–45.74), diabetes (OR 7.22, 2–25.99) and congestive heart failure (OR 10.22, 1.13–92.93) were statistically associated with increased mortality (p < 0.05). Also increased neutrophil (OR 1.26, 1.08–1.46), C-reactive protein (CRP) (OR 1.01, 1.003–0.02), lactate dehydrogenase (LDH), (OR 1.002, 1.001–1.004), D-dimer (OR 1.001, 1.002–1.003), and aspartate transaminase (AST) levels (OR 1.05, 1.02–1.08 were associated with increased mortality. Conclusion The presence of advanced age, active smoking, comorbidity, especially hypertension, diabetes, arrhythmia, coronary artery disease, congestive heart failure and neutrophil, C-reactive protein, lactate dehydrogenase, D-dimer and aspartate transaminase were associated with mortality. The efficacy of Lpv/r, warrants further verification in future studies.

Abstract
Background : Postoperative bronchopleural fistula (BPF) remains a serious complication due to its high morbidity and mortality. Although various endoscopic techniques have been defined for the closure of BPF previously, no standard algorithm yet exists. Aims To study the effectiveness and safety of various endoscopic procedures in an interventional pulmonology unit. Materials and Methods The medical data of 15 postoperative BPF patients, who were undergone endoscopic intervention were retrospectively investigated. Results The mean size of the fistulas determined by bronchoscopic evaluation was 7.93 ± 3.26 mm (range 3-15 mm). Applied procedures were as follows: stent implantation (n: 8, 53.3%), stent implantation and polidocanol application (n: 4, 26.7%), only Argon Plasma Coagulation (APC) application (n: 2,13.3%), polidocanol application (n: 1,6.7%). Complete fistula closure was achieved in three of the 15 patients (20%). The procedures were partly successful in five (33.3%) patients and failed to be successful in seven (46.6%) patients. Survival rates in regard to procedural success were determined and a statistically significant difference was found in five-year survival rates (P = 0.027, P < 0.05). Conclusion Our results demonstrated that bronchoscopic procedures can be safely and effectively performed in patients who were not eligible for surgery for various reasons.

Abstract
The COVID-19 pandemic has brought countries’ health services into sharp focus. It was drawn to our group’s attention that healthcare workers (HCWs) had a lower mortality rate against higher COVID-19 incidence compared to the general population in Turkey. Since risk of exposure to tuberculosis bacillus among healthcare workers are higher than the population, we aimed to investigate if there is a relationship between BCG and Mycobacterium tuberculosis exposure history with COVID-19 severity in infected HCWs. This study was conducted with 465 infected HCWs from thirty-three hospitals to assess the relationship between COVID-19 severity (according to their hospitalization status and the presence of radiological pneumonia) and BCG and Mycobacterium tuberculosis exposure history. HCWs who required hospital admission had significantly higher rates of chronic diseases, radiological pneumonia, and longer working hours in the clinics. Higher rates of history of contact and care to tuberculosis patients, history of tuberculosis, and BCG vaccine were observed in hospitalized HCWs. HCWs who had radiological pneumonia had a significantly increased ratio of history of care to tuberculosis patients and a higher family history of tuberculosis. The findings from our study suggest that the lower mortality rate despite the more severe disease course seen in infected HCWs might be due to frequent exposure to tuberculosis bacillus and the mortality-reducing effects of the BCG vaccine.

Abstract
Objective This study aimed to compare the pulmonary embolism (PE) location and clot burden on computed tomography pulmonary angiography (CTPA), the degree of right ventricular dysfunction (RVD), D-dimer, and cardiac troponin I (cTnI) levels, and the presence of a lower extremity deep venous thrombosis (DVT) in patients with and without cancer diagnosed with a non high risk pulmonary embolism (PE). Method We calculated Miller score for each patient for clot burden. The location of PE was also evaluated at CTPA. D-dimer and cardiac cTnI levels were measured. Patients had echocardiography for RVD and lower extremity color flow Doppler ultrasonography for DVT. Results The study included 71 patients with PE. The patients were divided into two groups according to the presence of cancer. There was no statistically significant difference for D-dimer levels (P=0.15), PE location (p=0.67), clot burden (P=0.34), RVD (P=0.28) and DVT (P=0.33) between groups (P=0.15). Cancer patients diagnosed as PE had statistically significantly higher levels of cTnI than those who were diagnosed as PE without cancer (P=0.03). Conclusion There was no significant difference between patients diagnosed as PE with and without cancer in terms of D-dimer levels, clot burden and emboli location, RVD and DVT. cTnI levels were higher in non-high risk PE patients with cancer than these patients without cancer.

Abstract
Sarcoidosis is a multisystemic granulomatous disease of unknown etiology. Renal involvement in sarcoidosis patients is occurred, but the incidence and prevalence is uncertain. The most common renal involvement of systemic sarcoidosis is nephrocalcinosis and interstitial nephritis. After sarcoidosis was diagnosed in a 31-year-old male patient, we performed a renal biopsy because of nephrotic range proteinuria and renal dysfunction. The collapsing variant of focal segmental glomerulosclerosis (FSGS) secondary to sarcoidosis was diagnosed by kidney biopsy.

Abstract
OBJECTIVE The role of Angiopoietin 2 (Ang 2), which is necessary for tumor growth, extension, and metastasis is not fully elucidated. The presented study aimed to investigate the relationship between Ang 2 staining intensity, expression rate in tumor tissue, and the stage of lung cancer. MATERIALS AND METHODS Fifty cases of lung cancer (34 non-small and 16 small cell cases) were included in the study. Immunohistochemistry was done to evaluate Ang 2 staining intensity and expression rate in tumor and stromal cells of lung cancer tissue. RESULTS Ang 2 was positive for 45 (90%) cases and negative for five (10%) cases (P = 0.04). There was a significant correlation between Ang 2 expression rate of expression and the histologic type of lung cancer (P = 0.033). Ang 2 expression rate in tumor cells of cancer tissues diagnosed with adenocarcinoma was low. There was a significant correlation between Ang 2 expression rate in stromal cells of cancer tissue and the type of lung cancer (P = 0.021). Stromal cell expression rate of Ang 2 in adenocarcinoma was found to be low. CONCLUSIONS As a result, the relationship between lung cancer stage and Ang 2 was documented with this study and the expression rate was found to be lower in adenocarcinomas. By this analysis, we can suggest that angiopoietins may be used as an option for targeted treatment in lung cancer.

Abstract
AIM Bronchiectasis develops as a result of genetic and environmental factors and its etiopathogenesis is not still clear. Recent studies have revealed that inflammatory cytokines, which are formed as a result of chronic infection and inflammation, play a role in the pathogenesis of bronchiectasis. For this purpose, the level of inflammatory cytokines in bronchiectasis and the presence or absence of a genetic predisposition with the gene polymorphism of these cytokines was investigated. MATERIAL AND METHODS A total of 60 patients, 40 study cases and 20 controls, which were monitored with the diagnosis of bronchiectasis were included in the study. In these individuals, cytokine levels [interleukin (IL)-6, IL-8, IL-10, and tumor necrosis factor (TNF)-α] in serum and bronchoalveolar lavage (BAL) fluid, along with the routine blood tests, were determined. Furthermore, the polymorphism in IL-6, IL-8, IL-10, and TNF-α cytokine genes and its frequency were studied in the obtained DNA by the automatic sequence analysis method and the results were compared. FINDINGS It was found that in serum and BAL fluid of the patient group, the IL-8 level was high, whereas the IL-10 level was low (P<0.05). No significant difference was detected in the other cytokines (P>0.05). It was found that in cytokine gene polymorphisms IL-8 -251 A/T, IL-10 -592 A/C, and IL-10 -819 T/C genotypes are associated with increased risk of bronchiectasis. It was detected that the IL-8 -251 A/T genotype increased the risk of having the disease by 4.19 fold. (OR =4.19, 95% CI =1.24-14.17, P=0.021). The IL-10 -592 C/A genotype increased the risk of having the disease by 5.71 fold (OR = 5.71, 95% CI =1.35-24.06, P=0.017) and the IL-10 -819 T/C genotype increased the risk of having the disease by 5.06 fold (OR =5.06, 95% CI =1.20-21.27, P=0.048). No significant correlation was found between the other polymorphisms and bronchiectasis. CONCLUSIONS The IL-8, IL-10 levels and the gene polymorphism of these cytokines differ. In addition to detecting higher levels of pro-inflammatory IL-8 and lower levels of anti-inflammatory IL-10, detection of gene polymorphism related to these two cytokines in bronchiectasis gives rise to the thought that cytokines may have role in a predisposition to bronchiectasis. However, as the number of patients is small, precise remarks could not be made on this subject. There is need for further studies include a larger number of patients.

Abstract
BACKGROUND Angiopoietin 2 (Ang-2) has an important role in tumor angiogenesis. In this study, Ang-2 levels of serum and bronchioloalveolar lavage fluids (BALF) in patients with lung cancer were measured and correlated with clinical and biochemical parameters. METHODS Thirty-five cases newly diagnosed with lung cancer and 18 controls with non-cancerous lung diseases were included in the study. Tumor histology, staging, metastasis, tumor markers, biochemical and clinical parameters were all recorded. RESULTS Serum Ang-2 levels were significantly higher in the lung cancer group compared to the control (lung cancer median: 2.42 ng/mL [2.19-2.98], control 0.67 [0.31-1.10]; P < 0.001), whereas Ang-2 levels in BALF were lower in the lung cancer group compared to the control (lung cancer median 0.41 ng/mL [0.22-0.79], control 0.67 [0.46-1.03]; P = 0.02). In the cancer group, higher serum Ang-2 levels (r = 0.52, P < 0.001) were associated with the stage of cancer. No significant correlation was observed between BALF Ang-2 levels and non-small cell lung cancer stages and small-cell lung cancer advanced stage (P = 0.793, r = 0.07). Serum Ang-2 levels were significantly higher in distant metastasis (M1) versus no distant metastasis (M0) (M1: 2.57 ng/mL [2.38-2.87], M0: 2.22 [1.49-2.40], P = 0.01). No significant correlation was observed between BALF Ang-2 levels and M1 (r = 0.11, P = 0.53). CONCLUSIONS Serum Ang-2 levels were significantly higher in lung cancer patients and positive correlations were observed between serum Ang-2, tumor stage, and metastasis.
