Objective:  Latent tuberculosis infection (LTBI) screening is strongly recommended in the pre-transplant evaluation of solid organ transplant (SOT) recipients, although it remains inadequate in many transplant centers. We decided to investigate pre-transplant TB risk assessment, LTBI treatment, and registry rates in Turkey., Material and Methods:  Adult SOT recipients who underwent tuberculin skin test (TST) and/or interferon-gamma release test (IGRA) from 14 centers between 2015 and 2019 were included in the study. An induration of ≥5 mm on TST and/or probable/positive IGRA (QuantiFERON-TB) was considered positive for LTBI. Demographic features, LTBI screening and treatment, and pre-/post-transplant TB history were recorded from the electronic database of transplantation units across the country and pooled at a single center for a unified database., Results:  TST and/or IGRA were performed in 766 (33.8%) of 2266 screened patients most of whom were kidney transplant recipients (n = 485, 63.4%). LTBI screening test was positive in 359 (46.9%) patients, and isoniazid was given to 203 (56.5%) patients. Of the patients treated for LTBI, 112 (55.2%) were registered in the national registry, and 82 (73.2%) completed the treatment. Tuberculosis developed in 6 (1.06%) of 563 patients who were not offered LTBI treatment., Conclusion:  We determined that overall, only one-third of SOT recipients in our country were evaluated in terms of TB risk, only 1 of the 2 SOT recipients with LTBI received treatment, and half were registered. Therefore, we want to emphasize the critical importance of pretransplant TB risk stratification and registration, guided by revised national guidelines.

Chronic obstructive pulmonary disease (COPD) that is the third leading cause of death in the world is one of the main economic burden. The cost is primarily due to COPD exacerbations and hospitalizations. We aimed to determine the factors associated with increasing costs in severe COPD exacerbation. It was a multicenter and prospective observational recording study. 294 patients who severe COPD exacerbation were included in the study. An amount of more than 429.58 euros was accepted as increasing costs (IC). Factors associated with IC were determined by regression analysis. Mean age was 69.90 ± 9.79/years (minimum: 40 maximum: 95), mean costs were 594.9 ± 70.9 euros. About 83.7% of the patients were male, 24.1% (71) were active smokers, and 81% (238) had at least 1 comorbidity. Factors associated with IC in the regression analysis were delay of discharge (due to prolonged consultation), antibiotic use longer than 7 days, need to enteral/parenteral feeding, application of pulmonary rehabilitation (physiotherapy) at hospitalization, and refusal to be discharged. The increasing costs in severe COPD exacerbation depends not only treatment but also the patient's social status and hospital-related factors. We think that the cost of severe COPD exacerbation can be reduced by interventions on interchangeable factors such as patient's social status and hospital-related factors.

Background: : Transbronchial lung cryobiopsy (TBLC) is a minimally invasive technique of the diagnosis of diffuse parenchymal lung diseases (DPLD). The aim of this study is to determine the clinical-radiological and histopathological characteristics of patients in whom cryobiopsy contributes to the diagnosis., Methods: : In this retrospective study, we searched for the medical records of patients who underwent TBLC from July 2015 to March 2020 at the pulmonology department of our university hospital clinic. Radiological images were evaluated by a chest radiologist experienced in DPLD. Prediagnosis was indicated by clinical-radiological findings. The final diagnosis was determined by the contribution of histopathological diagnosis. The agreement of pretest/posttest diagnosis and the diagnostic yield of TBLC were calculated., Results: Sixty-one patients with female predominance (59.0%) and current or ex-smoker (49.2%) made up the study population. We found the diagnostic yield of TBLC 88.5%. The most common radiological and clinical-radiological diagnosis was idiopathic pulmonary fibrosis (IPF) (n = 12, 19.6%) while the most common multidisciplinary final diagnosis was cryptogenic organizing pneumonia (COP) (n = 14, %22.9). The concordance of pre/posttests was significant (p < 0.001) with a kappa agreement = 0.485. The usual interstitial pneumonia (UIP) diagnosis was detected in six patients among 12 who were prediagnosed as IPF having also a suspicion of other DPLD by clinical-radiological evaluation (p < 0.001). After the contribution of TBLC, the multidisciplinary final diagnosis of 22(36.1) patients changed. The histopathological diagnosis in which the clinical-radiological diagnosis changed the most was nonspecific interstitial pneumonia (NSIP)., Discussion: We found the overall diagnostic yield of TBLC high. The pretest clinical-radiological diagnosis was often compatible with the multidisciplinary final diagnosis. However, TBLC is useful for the confirmation of clinical radiological diagnosis as well as clinical entities such as NSIP which is difficult to diagnose clinical-radiological. We also suggest that TBLC should be considered in patients whose clinicopathological IPF diagnosis is not precise.

Introduction: Anthracosis is a kind of pneumoconiosis that may cause parenchymal and bronchiolar injury and mediastinal lymphadenopathy. In this study, we aimed to investigate F-18 fluorodeoxyglucose (FDG) positron emission tomography/computerized tomography (PET/CT) findings of patients who had anthracosis diagnosis with endobronchial ultrasonography (EBUS)., Materials and Methods: The patients who underwent EBUS-transbronchial needle aspiration (TBNA) and were diagnosed with anthracosis in a five year period were included in the study. The diagnosis was confirmed by surgery/ radiological stability. Demographic characteristics such as age, sex, smoking status, and occupational and environmental exposures were recorded. The characteristics: diameter (short axis), shape, central hilar structure, necrosis sign, echogenicity, and margins measured by EBUS, and maximum standardized uptake value (SUV max value) by PET/CT of the lymph node stations were evaluated., Result: One hundred thirty-three patients with 239 lymph node stations were investigated. Biomass exposure was detected in nearly half of the patients (n= 55, 41.4%) and occupational exposure was detected in 32 (24.1%) patients. Eighty-six (64.7%) patients had more than 20 packs/years of smoking history. Most of the lymph nodes (80.8%) have a higher PET/CT SUV max value than 2.5. The mean diameter of the lymph nodes measured by thorax CT (16.2 ± 6.5 mm) and EBUS (12.7 ± 5.6 mm) did not show any difference according to PET/CT SUV max value of ≥2.5 or not (p> 0.05). Subcarinal lymph nodes were significantly larger than the other lymph node stations. The lymph nodes with necrosis sign (p= 0.028), absence of central hilar structure (p= 0.013), and heterogeneous echogenicity (p= 0.008) were statistically significantly related to higher SUV max value., Conclusions: Anthracosis should be considered as a cause of false-positive PET/CT results for mediastinal lymph nodes, especially in patients with a history of occupational and environmental exposure including biomass and smoking.

Background: Supervised high-intensity interval training (HIIT) has been proposed to be more effective than moderate-intensity continuous training (MICT) for improving exercise capacity, but there are not sufficient information effects of home-based HIIT and MICT in patients with myocardial infarction (MI)., Aims: To compare the effects of home-based HIIT and MICT in patients with MI., Methods: Twenty-one patients with MI were randomly assigned to one of two home-based exercise modes: HIIT group and MICT group. Home-based HIIT and MICT were performed twice a week for 12 weeks with an exercise intensity of 85-95% of heart rate (HR) reserve and 70-75% HR reserve, respectively. The primary outcome measure was functional capacity. Secondary outcomes included resting blood pressure and HR, peripheral oxygen saturation, pulmonary function and respiratory muscle strength, dyspnea severity, body composition (body fat%, body mass ındex (BMI), fat free muscle), peripheral muscle strength, and health-related quality of life (HRQoL)., Results: Functional capacity, measured by 6-minute walk test, increased in HIIT and MICT group (p < 0.05). Resting BP and HR, body fat%, and BMI were significantly decreased, and pulmonary functions, respiratory-peripheral muscle strength, and HRQoL were significantly increased in the both groups (p < 0.05). Home-based HIIT was more effective than MICT in improving pulmonary functions and lower extremity muscle strength (p < 0.05)., Conclusions: This study suggests that HIIT and MICT can be applied at home-based in patients with MI and play an important role in improving functional capacity, health outcomes, and HRQoL., Trial Registration: Clinical Trials Number: NCT04407624., (© 2021.

Background: In patients with coronavirus disease 2019, the gastrointestinal symptoms have been reported increasingly in addition to the respiratory system symptoms. The studies show that the prevalence of gastrointestinal system symptoms and how the gastrointestinal system contributes to the severity and prognosis of the disease is still not clear. This study aims to find the prevalence of gastrointestinal symptoms and the correlation between the gastrointestinal symptoms and the clinical results in hospitalized patients diagnosed with coronavirus disease 2019., Methods: This study retrospectively analyzes patients diagnosed with coronavirus disease 2019 and hospitalized in the pandemic unit between March 2020 and August 2020 and compares their demographic and clinical characteristics, laboratory and radiologic findings, coronavirus disease 2019 treatments received, the clinical course of the disease, and the gastrointestinal symptoms., Results: In our study, we included 322 patients diagnosed with coronavirus disease 2019 and hospitalized; 39 patients (12.1%) were admitted to the hospital with at least one gastrointestinal symptom (nausea and vomiting, diarrhea, abdominal pain, and the loss of taste). Nausea and vomiting are the most common gastrointestinal symptoms with a prevalence of 7.1%, followed by diarrhea with 2.8%, the loss of taste with 2.2%, and abdominal pain with 1.5%. The mean age and D-dimer levels of the patients showing gastrointestinal symptoms were lower than those who did not have any gastrointestinal symptoms. We did not find a significant correlation between the presence of the gastrointestinal symptoms and the severity of the disease, treatment received, risk of acute respiratory distress syndrome and septic shock, admission to the intensive care unit, the need for mechanical ventilation, the mortality rate or the length of hospitalization in the medical floor or the intensive care unit., Conclusion: In this study, we observed that 12.1% of coronavirus disease 2019 patients apply to the hospital due to gastrointestinal symptoms. Furthermore, the gastrointestinal symptoms do not seem to affect the severity and the course of the disease, it is important to identify coronavirus disease 2019 patients showing unusual symptoms such as the gastrointestinal symptoms at an early stage to protect healthcare professionals from infection risk.

Introduction: Tuberculosis (TB) mastitis is a rare form of granulomatous mastitis. We aimed to evaluate the clinical characteristics and prognosis of patients diagnosed with TB mastitis., Materials and Methods: A descriptive study was carried out on patients who were reported to national tuberculosis control authorities as having TB mastitis between 2003 and 2021. Demographic, histopathological, and radiological data including mammography, ultrasonography (US), and magnetic resonance imaging (MRI) were reviewed. All were followed up to 24 months and prognosis was also evaluated., Result: This study identified 29 TB mastitis patients who had been diagnosed using excisional biopsies. The mean age was 33.5 ± 10.1, all were premenopausal women. The most common symptom was breast mass (n= 24, %82.8), nearly half of the patients also had ipsilateral axillary lymphadenopathy (n= 14, 48.3). One-fourth of the patients had bilateral involvement (n= 7, 24.1%), and half of the patients (n= 16, 55.2%) presented with multiple masses. One patient had co-existing pulmonary TB. Predisposing factors for TB were not identified in any of the patients. Nearly half of the patients received prior mastitis treatment. The most common radiological finding was mass in both mammography and US. All patients received anti-tuberculosis treatment of a standard regimen for six to 21 months, three patients had a relapse but were finally cured., Conclusions: TB mastitis should be suspected in young and premenopausal women presenting with a breast mass and axillary lymphadenopathy in an endemic region. Radiological findings could not identify the diagnosis. A multidisciplinary approach including bacteriology and histopathology should be performed. Anti-tuberculosis treatment can be implemented successfully.

Background: Disease and aging-related factors may predispose chronic obstructive pulmonary disease (COPD) patients to impaired balance, although the underlying determinants of impaired balance in COPD patients are still unknown. The purpose of this study was to identify the determinants of impaired balance in COPD patients. Also, we aimed to determine which balance measures (clinical or laboratory tests) are more indicative in determining balance impairment in these patients., Methods: This cross-sectional study recruited 24 patients with moderate to severe COPD and 24 age-matched healthy subjects. Participants were evaluated regarding demographic and clinical data, previous falls history, lower limb muscle strength, exercise capacity, physical activity and balance level., Results: COPD patients exhibited significantly a longer test duration on timed up and go test, a higher sway index on the postural stability and lower directional control score on the limit of stability of Biodex balance system (all, p < 0.001) compared to healthy controls, whereas there was no difference in Berg balance scale score between groups (p > 0.05). Balance impairment of the patient group was significantly associated with nonpulmonary conditions, such as physical activity level, exercise capacity, lower limb muscle strength, and with fall history. Also, COPD patients represented significantly lower physical activity level and exercise capacity, weaker lower limb muscle strength than healthy controls (all, p < 0.001)., Conclusions: Patients with moderate to severe COPD exhibit apparently important reductions in balance control that is directly associated with nonpulmonary consequences and fall history. These results may be extremely important to fall prevention and to guide the development of interventions for this population., (© 2021. Springer-Verlag GmbH Austria, part of Springer Nature.)

Chronic obstructive pulmonary disease (COPD) is an important public health problem that manifests with exacerbations and causes serious mortality and morbidity in both developed and developing countries. COPD exacerbations usually present to emergency departments, where these patients are diagnosed and treated. Therefore, the Emergency Medicine Association of Turkey and the Turkish Thoracic Society jointly wanted to implement a guideline that evaluates the management of COPD exacerbations according to the current literature and provides evidence-based recommendations. In the management of COPD exacerbations, we aim to support the decision-making process of clinicians dealing with these patients in the emergency setting., (Copyright: © 2021 Turkish Journal of Emergency Medicine.)

Objectives: Management of chronic obstructive pulmonary disease (COPD) includes interventions such as improving skills in coping with the disease. We aimed to examine the effect of self-management training on the quality of life and functional parameters in patients with moderate to severe COPD., Materials and Methods: Sixty-one consecutive patients with COPD were recruited in the study prospectively. The patients were randomized into two groups: self-management training (n=31) and standard care (n=30). Each patient was evaluated by spirometry, COPD assessment test (CAT), St George's respiratory questionnaire (SGRQ), hospital anxiety and depression scale (HADS), modified British Medical Research Council (mMRC) dyspnea scale, and short form-36 (SF-36). A team of physiotherapists, psychologists, pulmonary disease specialists, and dietitians provided self-management training and biweekly counseling via phone. At the end of three months, both the groups were re-evaluated using the same assessment parameters., Results: We found no significant difference between the baseline demographic characteristics of the self-management training and standard care groups. We observed a reduction in CAT (p<0.001), SGRQ impact (p=0.013), activity subscales (p<0.001) and the total scores (p=0.020), and HADS anxiety (p=0.012) and depression (p=0.014) scores in the self-management training group after the education session. A significant increase in SF-36 physical function score was also observed (p=0.008). No significant improvement in the functional parameters was observed in either group; however, the change in FEV1 was more pronounced in the self-management training group than in the control group (p=0.017). The hospital readmissions and 1-year survival rates were similar for both the groups after receiving education (p>0.05)., Conclusion: Our results suggest that the self-management training of the patients with COPD improves the quality of life and reduces the symptoms of depression and anxiety. Therefore, at the least, self-management training should be done as the first step of pulmonary rehabilitation in patients with COPD who cannot access pulmonary rehabilitation facilities.

Introduction: Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are acute onset syndromes affecting the lungs, which develop for several reasons and are characterized by hypoxemia and diffuse lung infiltration. The activity of thymoquinone (TQ) is known in acute lung injury. It is considered that it could be effective in ALI/ARDS treatment by ensuring possible COX-2 inhibition., Aim: By this study was to show the protective activity of TQ in lipopolysaccharide (LPS) induced acute lung injury.Material and methods: A total of 28 BALB/c male mice were randomized to 4 groups of 7 as the Control group, TQ group (3 mg/kg), LPS group (5 mg/kg) and TQ treatment group. TQ was administered intraperitoneally 1 hour before the intratracheal administration of LPS (5 mg/kg). The mice were sacrificed 6 hours after the LPS administration and the lungs were extracted for histopathological examination. All experimental procedures complied with the requirements of the Animal Care and Ethics Committee of Dokuz Eylul University., Results: When all the study groups were compared, significant differences were found between the groups in terms of the degrees of neutrophil migration ( p = 0.042), intra-alveolar hemorrhage ( p = 0.004) and alveolar destruction ( p < 0.0006). A significant recovery was observed in the lung histopathological changes (neutrophil migration, intra-alveolar hemorrhage and alveolar destruction) in the TQ treatment group., Conclusions: The results of this study showed that TQ may have a protective effect against LPS-induced acute lung injury. The possible mechanism could be considered to be cyclooxygenase 2 (COX-2) inhibition., Competing Interests: Authors report no conflict of interest., (Copyright © 2020 Polish Society of Cardiothoracic Surgeons (Polskie Towarzystwo KardioTorakochirurgów) and the editors of the Polish Journal of Cardio-Thoracic Surgery (Kardiochirurgia i Torakochirurgia Polska).)

Introduction: In this study it is aimed to evaluate the prevalence of smoking, factors affecting smoking status, and the attitudes of the elementary school students towards the smoking prohibition law which was approved in July 2009, in city., Materials and Methods: The universe of this descriptive study was 6th-7th-8th class, 8236 urban and 4937 semi-urban, total 13.173 elementary schools students in city center. Study population was determined on the basis of a previous study in which the smoking trial prevalence was found 17.5%, 831 students in 6 urban 3 semi-urban, total 9 schools were chosen randomly. A questionnaire was prepared investigating smoking status, the effects of smoking and family history. Among the 9 chosen schools, the questionnaire was applied to 615 students. SPSS 14.0 statistical package was used., Result: Forty-seven percentages of the students were female. Prevalence of smoking trial was found 23.5% (16% in urban, 35% in semi-urban schools) while the prevalence of smoking was 7.1% (1.7% in urban, 15.7% in semi-urban schools). Mean age of first smoking trial was 10.04 ± 2.3. The smoking prohibition law was supported by 86.6% of the students, the warnings on the cigarette package was thought to be effective by 43.3% students and 35.2% of the students were exposed to passive smoke. Male gender, social status, education level of the family, smoker family member or close friends were found to be important risk factors for smoking prevalence of the students., Conclusions: The early onset of smoking should guide the smoking struggle be concentrated in elementary school especially in semi-urban areas where the smoking prevalence is high.

Introduction: Amyotrophic lateral sclerosis (ALS) is a progressive neuromuscular disease with devastating and fatal respiratory complications. Diaphragm pacing stimulation (DPS) is a treatment option in diaphragm insufficient ALS patients. Ventilatory insufficiency depending on diaphragmatic failure is treated by the present study aimed to investigate prognostic value of preoperative clinical and functional characteristics of ALS patients undergoing implantation of a DPS system and to determine appropriate indications for the DPS system., Methods: The study included 34 ALS patients implanted with DPS system. All patients underwent multidisciplinary and laboratory evaluations before the surgery. The laboratory examinations included pulmonary function tests and arterial blood gas analysis. Survival rates were recorded in a 2-year follow-up after the surgery., Results: Twenty-eight of 34 patients with ALS survived after a 2-year follow-up. These patients were younger than those who died and had the disease for a longer time; however, the differences were not significant. Both right and left hemidiaghragms were thicker in the survived patients ( P < 0.0001 for each). Pulmonary function tests revealed no significant differences between the patients who survived. Arterial blood gas analysis demonstrated lower partial pressure of carbon dioxide in the survived patients ( P = 0.025)., Conclusions: DPS implantation was more efficacious in ALS patients with mild respiratory failure and thicker diaphragm. Predictors of long-term effectiveness of DPS system are needed to be addressed by large-scale studies., Competing Interests: There are no conflicts of interest.

Objectives: This study aimed to investigate the additional diagnostic value of endobronchial biopsy (EBB) in the diagnosis of pulmonary sarcoidosis., Materials and Methods: This retrospective cross-sectional study included 59 patients with a preliminary diagnosis of sarcoidosis who were admitted to the Pulmonary Diseases Outpatient Clinic of a tertiary healthcare center between January 2005 and October 2012. The socio-demographic characteristics of the patients as well as clinical and radiological findings were recorded. All patients, irrespective of the presence of an endobronchial lesion (EBL), underwent fiberoptic bronchoscopy (FOB); two to four specimens were taken using EBB from the carina of the right middle lobe in the patients with EBL., Results: Of the patients, 39 (66.1%) had normal bronchoscopic findings, while 5 had EBL. Diagnosis was based on EBB in 11 patients (18.6%). Six patients (15.3%) with normal bronchial mucosae were pathologically diagnosed by EBB. There was no statistically significant relationship between the diagnostic ratio of EBB and disease stage, extrapulmonary involvement, FOB findings, elevated lymphocyte rate in bronchoalveolar lavage (≥ 13%), a CD4/CD8 ratio of ≥ 3.5, and serum angiotensin-converting enzyme (ACE) level (p> 0.05)., Conclusion: EBB not only offers the advantage of a high diagnostic ratio in patients with mucosal abnormalities but also contributes to pathological diagnosis in patients with normal mucosa. We recommend using EBB to support diagnosis with a low complication rate for patients undergoing FOB with a preliminary diagnosis of sarcoidosis in healthcare centers, where endobronchial ultrasound (EBUS) is unavailable., Competing Interests: Conflict of Interest: No conflict of interest was declared by the authors.

Pneumocystis pneumonia (PCP) caused by Pneumocystis jirovecii (P. jirovecii) is an opportunistic pulmonary infection that occurs in immunocompromised patients. Here, a 49-year-old female patient who was admitted to our hospital with respiratuary distress and whose bronchoalveolar lavage (BAL) fluid specimens had P. jirovecii and Aspegillus fumigatus was presented. She had been treated with corticosteroids because of interstisial lung disease and she was also diabetic. It is important to define the coinfection developed in the presence of immunosuppression.
