RESUMO
Introduction: Tuberculosis (TB) is an infectious disease that can be fatal if left untreated or poorly treated, and it is associated with many morbidities. Deaths may provide better understanding of the associated factors and help guide interventions to reduce mortality. In this study, it was aimed to reveal some of the features that predict hospital mortality in patients with TB and to present some alarming findings for clinicians. Materials and Methods: Patients who had been hospitalized with the diagnosis of TB between January 2008 and December 2018 were included and analyzed retrospectively. In-hospital mortality because of any TB disease after the initiation of treatment in patients admitted to the TB Ward and the primary cause of mortality were taken as endpoint. Result: A total of 1321 patients with a mean age of 50.1 years were examined. Total mortality was 39.4% (521 deaths) and 13.1% were in-hospital deaths (173 deaths). Of the deaths, 61.8% (n= 107) occurred during the first month after TB treatment were started. On univariate analysis, age over 48.5 years, Charlson comorbidity index, extension of radiological involvement, hypoalbuminemia and lymphopenia were most predictive variables with higher odds ratios (respectively, p<0.001 for all). Conclusions: In-hospital tuberculosis disease mortality is related with older age, cavitary or extensive pulmonary involvement, low albumin levels, unemployment, cigarette smoking and especially those with concomitant malignancy and chronic pulmonary disease.

ABSTRACT Objective: Various studies have shown that diabetes mellitus (DM) increases the risk of thrombosis in the venous system as well as in the arterial system. In this study, it was aimed to evaluate the association between admission blood glucose levels and clinical severity, recurrence, and mortality in pulmonary embolism in patients with DM. Materials and methods: This study was designed as a retrospective cross-sectional study. Patients with DM who were admitted to a tertiary care hospital due to pulmonary embolism (PE) between 2014 and 2019 were included. Demographic characteristics, radiological findings, clinical class of embolism, and mortality data were retrieved from hospital records. Patients with and without recurrent disease, as well as patients who survived and died, were compared. Also, patients were classified according to quartiles of admission blood glucose levels. The quartiles were compared in terms of mortality, clinical, class, and recurrence. Results: Two hundred ninety-three patients with DM and PE were included in the study. Patients with adverse outcome had significantly higher admission blood glucose levels (respectively, 197.9 ± 96.30 mg/dL vs. 170.7 ± 74.26 mg/dL; p = 0.03). Patients in the third and fourth quartile of admission blood glucose levels (>152 mg/dL) had significantly more severe disease with a higher proportion of massive and sub-massive PE and higher pro-BNP levels (respectively, p = 0.01 and 0.02). Conclusion: Non-survived patients and recurrent disease were associated with higher admission blood glucose levels. Also, patients with admission blood glucose levels higher than 152 mg/dL tend to have clinically more severe diseases.
RESUMO
Protein-inorganic hybrid nanoflowers are new multifunctional materials shown enhanced catalytic performance. Specially, they are used as catalyst and dye decolorizer via Fenton reaction. In this study, the Myoglobin-Zn (II) assisted hybrid nanoflowers (MbNFs@Zn) were fabricated by using myoglobin and zinc (II) ions in different synthesis conditions. The optimum morphology was characterized SEM, TEM, EDX, XRD, and FT-IR. The hemisphere and uniform morphology was obtained at pHâ 6 and 0.1â mg mL-1 . The size of MbNFs@Zn are 5-6â µm. The encapsulation yield was â¼95 %. In the presence of H2 O2 , the peroxidase mimic activity of MbNFs@Zn was spectrophotometrically investigated in the different pH values (4-9). The highest peroxidase mimic activity was found as 3.378â EU/mg at pHâ 4. MbNFs@Zn was exhibited 0.28â EU/mg after eight cycles. MbNFs@Zn has lost about 92 % of its activity. The usability of MbNFs@Zn for decolorization of azo dyes such as Congo red (CR), and Evans blue (EB) was researched at different times, temperatures and concentrations. The decolorization efficiency was found maximum as 92.3 % and 88.4 % for EB and CR dyes, respectively. MbNFs@Zn has perfect properties such as enhanced catalytic performance, high decolorization efficiency, stability and reusability, and can be excellent potential materials for many industrial applications.

Although Cushing's Syndrome (CS) is usually caused by pituitary/adrenal adenomas, in the remaining few cases, Adrenocorticotrophic hormone (ACTH) is secreted by extrapituitary neuroendocrine tumors (NET). In typical pulmonary / bronchial carcinoid tumors leading to ectopic ACTH syndrome (EAS). The main principle of treatment is the localization of the ACTH-secreting tumor and its surgical removal. In this case report, we aimed to present two typical carcinoid cases, whose ACTH and cortisol levels returned to normal after lung surgery for ectopic ACTH. One of the cases, a 32-year-old female patient with CS symptoms and signs, was referred to our department after detecting a lesion in the left lower lobe in the thorax CT, which did not show an obvious focus on cranial MRI. The other patient, a 36-year-old male, had previously undergone adrenalectomy for Cushing's syndrome and was admitted to the emergency department due to adrenal insufficiency. The lesion seen in the right lower lobe on thorax CT was evaluated as an ectopic ACTH focus. After the tumors of the patients were resected according to surgical principles, CS clinic regressed, and ACTH and cortisol values returned to normal. Pathological examinations of the surgically resected tumors were reported as typical carcinoid. With surgically removed typical carcinoids tumors, excellent longterm survival results can be achieved and hypercortisolism can be controlled.

OBJECTIVES: In recent years, a correlation between prognosis of various cancers and inflammation has been emphasized in many studies. Uric acid which is a purine metabolite is one of the serum inflammation markers. Albumin is a major component of serum protein and it is used as a parameter reflecting nutritional status and cancer aggressiveness. Here, we have investigated whether preoperative serum uric acid levels, albumin levels, and uric acid to albumin ratio predict lymph node metastasis in non-small cell lung cancer treated surgically by VATS. METHODS: The medical records of patients underwent VATS lobectomy-segmentectomy for non-small cell lung cancer between January 2015 and December 2020, were reviewed retrospectively. Cut-off values of preoperative serum uric acid, albumin and uric acid to albumin ratio were determined by Receiver Operating Characteristics (ROC) analysis. Groups with and without lymph node metastasis were created according to hilar and/or mediastinal lymph node metastasis. In addition, high and low groups were created according to preoperative uric acid levels and uric acid to albumin ratio. Pearson chi-square test was used investigate whether any significant correlation between the groups. RESULTS: A total of 115 patients were included in the study. Lymph node metastasis in N1 and N2 stations was detected in 11 and 18 patients, respectively. Cut-off values for uric acid and uric acid to albumin ratio were 5.97 mg/dL and 1.28x10-3, respectively. There was a statistically significant correlation between lymph node metastasis and high uric acid levels (p=0.008, OR: 3.2) and high uric acid to albumin ratio (p=0.03, OR: 2.6). CONCLUSION: Preoperative serum uric acid and uric acid to albumin ratio can predict the lymph node metastasis in non-small cell lung cancer treated surgically by video assisted thoracic surgery.

Objectives: Regular follow-up of patients with lung cancer treated surgically is crucial to detect local recurrence or distant metastasis of the tumor. Postoperative follow-ups are performed with thorax computed tomography (CT) and, if necessary, positron emission tomography (PET)/CT. Sometimes, inflammatory tissue reactions due to the materials used during the surgery for hemostasis may cause the appearance of tumor recurrence in imaging modalities. In this study, we presented that oxidized regenerated cellulose (ORC) used intraoperatively may cause false tumor recurrence on PET/CT. Methods: The records of patients who had local tumor recurrence after lung cancer surgery was reviewed retrospectively. Inclusion criteria were the presence of local recurrence of cancer on PET/CT, specification of using ORC in the surgical notes, and histopathological diagnosis of the recurrence site of tumor was reported as a foreign body reaction. Data of patients were collected according to age, gender, surgery performed, adjuvant therapy status, resolution status and time ORC, and standard uptake value of 18F-fluorodeoxyglucose on PET/CT. Results: Eleven patients (1 female, 10 males) who met the criteria were included in the study. The median age was 64. Histopathological results of all patients were reported as foreign body reactions. The median detection time of PET/CT positivity after surgery was 139 days (range: 52-208 days). False tumor recurrence was resolved in 8 patients (72.7%) in their control radiological examinations and median resolution time was 334 days (range: 222-762 days). The median maximum standard uptake value of the lesions was 6.2 (1.7-11) on the PET/CT. Conclusion: ORC used intraoperatively in patients undergoing surgery for lung cancer may cause false tumor recurrence in imaging modalities in postsurgical follow-ups. When tumor recurrence is suspected in the follow-up of these patients, histopathological confirmation is necessary to prevent unnecessary operations and treatments.

Background: Malignant pleural mesothelioma (MPM) is an aggressive pleural malignancy, and despite all multimodal treatment modalities, the 5-year overall survival rate of patients with MPM is less than 20%. In the present study, we aimed to analyze the surgical and prognostic outcomes of patients with MPM who received multimodal treatment. Methods: In this retrospective, single-center study, the records of patients who underwent surgery for MPM between January 2010 and December 2020 at our department were reviewed retrospectively. Results: Sixty-four patients were included in the study, of whom 23 (35.9%) were women and 41 (64.1%) were men. Extrapleural pneumonectomy, pleurectomy/decortication, and extended pleurectomy/decortication procedures were performed in 34.4%, 45.3%, and 20.3% of patients, respectively. The median survival of patients was 21 months, and the 5-year survival rate was 20.2%. Advanced tumor stage (hazard ratio [HR], 1.8; p=0.04), right-sided extrapleural pneumonectomy (HR, 3.1; p=0.02), lymph node metastasis (HR, 1.8; p=0.04), and incomplete multimodal therapy (HR, 1.9; p=0.03) were poor prognostic factors. There was no significant survival difference according to surgical type or histopathological subtype. Conclusion: Multimodal therapy can offer an acceptable survival rate in patients with MPM. Despite its poor reputation in the literature, the survival rate after extrapleural pneumonectomy, especially left-sided, was not as poor as might be expected.
RESUMO
BACKGROUND: Coronavirus disease 2019 (COVID-19) related chronic lung changes secondary to severe disease have become well known. The aim of this study was to determine the risk factors that affect the development of interstitial lung disease in subjects with COVID-19 pneumonia who were hospitalized. METHODS: Patients hospitalized with COVID-19 pneumonia between June 2020 and March 2021 were retrospectively analyzed. Smoking histories, comorbidities, reverse transcriptase polymerase chain reaction test results, laboratory parameters at the time of the diagnosis, oxygen support, the use of corticosteroids with dosage and duration data, the need for ICU care were recorded. High-resolution computed tomographies (HRCT) were obtained for study population in their 3-6 months follow-up visit. The subjects were classified as having residual parenchymal lung disease if a follow-up HRCT revealed parenchymal abnormalities except pure ground-glass opacities (the residual disease group). The control group consisted of the subjects with normal chest radiograph or HRCT in their follow-up visit or the presence of pure ground-glass opacities. Two groups were compared for their demographic and clinical abnormalities, laboratory parameters, treatment regimens, and the need for ICU care. RESULTS: The study included 446 subjects. The mean ± SD age was 58.4 ± 13.87 years, with 257 men (57.6%). Although 55 subjects had normal HRCT features on their follow-up HRCT, 157 had abnormal lung parenchymal findings. Univariate logistic regression analysis revealed statistically significant results for age, sex, corticosteroid treatment, and the need for ICU care for predicting interstitial lung disease development (P < .001, P = .003, P < .001, and P < .001, respectively). Also, the residual disease group had significantly higher leukocyte and neutrophil counts and lower lymphocyte counts (P < .001, P < .001, P = .004, respectively). Correlated with these findings, neutrophil-to-lymphocyte ratios and platelet-to-lymphocyte ratios were significantly higher in the residual disease group (P < .001 and P = .008, respectively). CONCLUSIONS: Residual parenchymal disease was observed 3-6 months after discharge in one third of the subjects hospitalized with COVID-19 pneumonia. It was observed that interstitial lung disease developed more frequently in older men and in those subjects with more-severe disease parameters.

Background Mediastinal cysts are benign lesions that may be seen in adulthood as well as in childhood. Mostly congenital lesions constitute 20 to 32% of lesions located in the mediastinum. The main cystic masses are congenital benign cysts (bronchogenic, esophageal replications, neuroenteric, pericardial and thymic cysts), meningocele, mature cystic teratoma, and lymphangioma. In this study, we aimed to analyze the mediastinal cysts operated in our clinic according to the histopathological type, surgical type, morbidity rates and to contribute to the literature on these rare lesions. Methods The records of patients with mediastinal cysts who were operated in Gazi University Faculty of Medicine Department of Thoracic Surgery, between January 2013 and June 2021, were reviewed retrospectively. Results A total of 32 patients were included the study. Thirteen (40.6%) of the patients were male and 19 (59.4%) were female. The mean age was 45 (range: 12-71). The most common symptom in patients was chest pain with 12 patients. Histopathologically, the most common subtype was thymic cyst. Video-assisted thoracic surgery was applied in 19 patients (59.3%), thoracotomy in 8 patients (25%), and sternotomy in 5 patients (15.63%). There was no mortality. Conclusion In patients with mediastinal cysts, the prognosis after complete excision is excellent and rates of morbidity and mortality associated with surgery are low.
RESUMO
BACKGROUND: The COVID-19 pandemic, which first appeared in Wuhan, China, in December 2019 and spread rapidly around the globe, continues to be a serious threat today. Rapid and accurate diagnostic methods are needed to identify, isolate and treat patients as soon as possible because of the rapid contagion of COVID-19. In the present study, the relation of the semi-quantitative scoring method with computed tomography in the diagnosis of COVID-19 in determining the severity of the disease with clinical and laboratory parameters and survival of the patients were investigated along with its value in prognostic prediction. MATERIAL AND METHOD: A total of 277 adult patients who were followed up in the chest diseases clinic because of COVID-19 pneumonia between 11.03.2020 and 31.05.2020 were evaluated retrospectively in the present study. Both lungs were divided into five regions in line with their anatomical structures, and semiquantitative radiological scoring was made between 0 and 25 points according to the distribution of lesions in each region. The relations between semiquantitative radiological score and age, gender, comorbidity, and clinical and laboratory parameters were examined. RESULTS: A significant correlation was detected between advanced age, lymphopenia, low oxygen saturation, high ferritin, D-dimer, and radiological score in the univariate analysis performed in the present study. The cut-off value of the semiquantitative radiology score was found to be 15 (AUC: 0.615, 95% CI: 0.554-0.617, p = 0.106) in ROC analysis. The survival was found to be better in cases with a radiology score below 15, in Kaplan-Meier analysis (HR: 4.71, 95% CI: 1.43-15.46, p < 0.01). In the radiological score and nonparametric correlation analyses, positive correlations were detected between CRP, D-dimer, AST, LDH, ferritin, and pro-BNP, and a negative correlation was found between partial oxygen pressure and oxygen saturation (p = 0.01, r = 0.321/0.313/0.362/0.343/0.313/0.333/-0.235/-0.231, respectively) CONCLUSION: It was found that the scoring system that was calculated quantitatively in thorax HRCTs in Covid-19 patients is a predictive actor in determining the severity and prognosis of the disease in correlation with clinical and laboratory parameters. Considering patients who have a score of 15 and above with semiquantitative scoring risky in terms of poor prognosis and short survival and close follow-up and early treatment may be effective to reduce mortality rates.

Protein-inorganic hybrid nanoflowers have tremendous potential in bionanotechnology due to their simple method of preparation, high stability and superior properties. Considering these features, the present study was designed to investigate the artificial blood substitution potentials of hemoglobin-inorganic hybrid nanoflowers. In this context, hemoglobin-inorganic hybrid nanoflowers (Cu-NF, Co-NF and Zn-NF) were synthesized using with different metal ions (copper, cobalt and zinc), then their oxygen carrying capacity, the hemolytic studies, inâ vitro oxidant/antioxidant capacity levels and oxidative stress index were reported for the first time. The present findings have revealed that Zn-NF had significant oxygen content and artificial oxygen carriers (AOC), as well as a significantly low percent hemolysis rate and a safe standard value. Also, hemolysis rate decreased along with the increases in hemoglobin content coupled with increments in nanoflower concentrations. The percentage hemolysis rate was lower than all nanoflowers at low free hemoglobin concentration, but hemolysis rates also increased with increments in concentration. The results showed that in general, Zn-NF stands out with its high total antioxidant capacity and low total oxidant capacity and oxidative stress index. The obtained results showed that Cu-NF and Co-NF, especially Zn-NF might be considered as a potential superior artificial oxygen carrier. Therefore, this nanoflower system might be act as an efficient material as a blood substitute in the near future.

BACKGROUND: To detect the extent to which physical impairments are observed in patients with lung cancer awaiting lung surgery, exercise capacity, muscle strength, physical activity, dyspnea, and quality of life (QOL) were objectively compared between the patients and healthy individuals in current study. METHODS: Patients with lung cancer (n = 26) and healthy individuals (n = 21) were included. Exercise capacity, respiratory (maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP)) and quadriceps femoris muscle strength, physical activity, dyspnea and QOL were evaluated using 6-min walk test (6-MWT), a mouth pressure device, a hand-held dynamometer, a metabolic holter device, Modified Medical Research Council dyspnea scale and European Organization for Research and Treatment of Cancer QOL Questionnaire C30 version 3.0, respectively. RESULTS: The 6-MWT distance (mean difference: 78.97 m), percentages of predicted MIP and MEP values, physical activity parameters (energy expenditures, physical activity duration, average metabolic equivalent and number of steps) and QOL subscales scores (functional, social function and global health status) were significantly lower in the patients than healthy individuals (p < 0.05). Dyspnea perception and other QOL subscales scores (symptom and fatigue) were significantly higher in patients than healthy individuals (p < 0.05). No significant difference was prevalent in quadriceps femoris muscle strength (p > 0.05). Sixteen (66.7%) patients were sedentary. DISCUSSION: Severe reductions in exercise capacity, respiratory muscle strength, and physical activity level, poorer QOL and evident dyspnea exist in preoperative patients with lung cancer. Therefore, patients should be included in early protective rehabilitation program including aerobic exercise, respiratory muscle training and physical activity counseling before lung surgery.

Background/aim: As the number of case reports related to the new type of coronavirus (COVID-19) increases, knowledge of and experience with the virus and its complications also increase. Pleural complications are one relevant issue. We aimed in this study to analyze pleural complications, such as pneumothorax, pneumomediastinum, and empyema, in patients hospitalized with the diagnosis of COVID-19 pneumonia. Materials and methods: The files of patients who have pleural complications of COVID-19 pneumonia and were consulted about thoracic surgery between March 2020 and December 2020 were retrospectively reviewed. The data of the patients were analyzed according to age, sex, length of stay, treatment method for pleural complications, mortality, severity of COVID-19 pneumonia, tube thoracostomy duration, and presence of a mechanical ventilator. Results: A total of 31 patients fulfilling the inclusion criteria were included in the study. There were 11 female (35.5%) and 20 male (65.5%) patients. The most common complication was pneumothorax in 20 patients (65%). The median duration of hospitalization was 22 days and the mortality rate was 71%. Mortality was significantly higher in patients on mechanical ventilation (p = 0.04). Conclusion: The mortality rate is very high in patients with pleural complications of COVID-19 pneumonia. Pneumothorax is a fatal complication in critically ill patients with COVID-19 pneumonia.

The increasing number of studies published on coronavirus disease 2019 (COVID-19) pneumonia has improved our knowledge of the disease itself and its complications. Despite a considerable number of publications on COVID-19 pneumonia-associated pneumothorax, no article on spontaneous hemopneumothorax has been found in the English-language literature. According to published case reports, pneumothorax generally occurs in hospitalized patients during treatment, whereas cases that arise in the late period after discharge are exceptional. Herein, we present a case of spontaneous hemopneumothorax occurring as a late complication of COVID-19 pneumonia on day 17 after discharge.
RESUMO
Objectives: The major scores associated with the mortality after COPD exacerbations were; DECAF, CURB-65, PSI and BAP-65 scores. We aimed to compare these scores in predicting 30- and 90-day mortality in patients hospitalized with exacerbation of COPD.Methods: The data of 141 patients who were hospitalized with the diagnosis of COPD exacerbation between January 2018 and March 2019 and accepted to participate in the study were prospectively recorded.Results: Age, mean modified-medical-research-council (mMRC) dyspnea score, pleural effusion, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), presence of atrial fibrillation (AF), PaCO2 pressure values were found to be significantly higher at both 30 and 90-days deceased group, while hemoglobin, albumin and pH values were significantly lower (all p < 0.05). DECAF, CURB-65, PSI and BAP-65 scores were significantly higher for both 30 and 90-days mortality (all p < 0.05). DECAF, CURB-65, PSI, BAP-65 scores, PLR, NLR predicted to 30 day and 90 day mortality. But, CURB-65 found (OR 2.968 and 2.284, respectively) superior to others in predicting 30 and 90-days mortality.Conclusions: CURB-65 score is a significant, simple and feasible score for predicting 30 and 90 days mortality in COPD exacerbation and may be routinely used in all patients hospitalized with COPD exacerbation.

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.
RESUMO
BACKGROUND: This study aims to identify the prognostic factors in Stage IIIA non-small cell lung cancer and to investigate whether there was a significant difference in terms of overall survival and diseasefree survival among the subgroups belonging to this disease stage. METHODS: Between January 2010 and December 2018, a total of 144 patients (125 males, 19 females; median age 60 years; range, 41 to 80 years) who were operated for non-small cell lung cancer in our clinic and whose pathological stage was reported as IIIA were retrospectively analyzed. Data including demographic and clinical characteristics of the patients, histopathological diagnosis, the standardized uptake value of the mass on positron emission tomography-computed tomography, tumor diameter, type of surgery, lymph node metastasis status, visceral pleural invasion, and overall and disease-free survival rates were recorded. RESULTS: The median survival was 39 (range, 27.8 to 46.1) months and the five-year overall survival rate was 28%. The mean tumor diameter was 4.3±2.7 cm. The median disease-free survival was 37 (range, 28.1 to 48.6) months and the five-year disease-free survival rate was 26.9%. In the multivariate analysis, overall survival and disease-free survival in T2N2M0 subgroup were significantly worse than the other subgroups. The other poor prognostic factors of survival were the standardized uptake value of the tumor, pneumonectomy, and histopathological subtypes other than squamous cell carcinoma and adenocarcinoma. Parietal pleural invasion was significantly associated with worse disease-free survival rates. CONCLUSION: Our results showed that there may be significant survival differences between subgroups created by tumor histopathology, lymph node invasion and the type of surgery in a heterogeneous lung cancer stage.
