RESUMO
Liver transplant is an important treatment option for end-stage liver disease, and living related donation is an option to shorten or eliminate the waiting period for the patients, especially when shortage of organs is of concern. It is crucial to provide optimal safety for the donors and to thoroughly examine them preoperatively in order to decrease perioperative and postoperative complications. Here, we report the case of a living donor who had undergone a left liver lobectomy and on postoperative day 2 presented with a radiologically severe pulmonary embolism, despite the absence of any risk factor for venous thromboembolism or pulmonary embolism. The patient was treated with tissue plasminogen activator and heparin infusions and was discharged 1 week later.

BACKGROUND: Adipokines play an important role in the regulation of inflammatory responses toward infections, including COVID-19. This study aimed to investigate the role of chemerin, adiponectin, and leptin in prognosis and post-COVID lung sequelae in hospitalized patients with COVID-19. METHODS: Serum levels of the three adipokines were measured upon admission of polymerase chain reaction-confirmed patients with COVID-19 who were followed up for 6 months for the clinical outcome and lung sequelae formation. RESULTS: A total of 77 patients were included in the study. Of the 77 patients, 58.4% were males, and the median age was 63.2 ± 18.3 years. Fifty-one patients (66.2%) had a good prognosis. Among adipokines, only chemerin was significantly lower in the bad prognosis group (P < 0.05), and the serum levels showed a negative correlation with age (rho = -0.238; P < 0.05). Leptin levels were negatively correlated with gamma glutamyl transferase levels, which were significantly higher in the bad prognostic group (rho = -0.240; P < 0.05). Twenty-four patients had no lung sequelae, and 20 developed sequelae within 6 months after infection. Chemerin/adiponectin ratio with a cut-off value of 0.96 and an area under the curve 0.679 (P < 0.05) might predict the sequelae formation. CONCLUSIONS: Chemerin levels are lower, especially in patients with a bad prognosis, and the chemerin/adiponectin ratio might predict the development of lung sequelae in patients with COVID-19.

Introduction: Pulmonary function tests are used in the evaluation of the respiratory system. Maneuvers during spirometry can create aerosols and spread viruses such as SARS-CoV-2. Measures due to the pandemic can negatively affect both the number and the quality of the spirometry tests. There are no comparative studies on this subject. Materials and Methods: The tests conducted in the spirometry laboratory between November 2019 and November 2021 were evaluated. Result: Four hundred forty patients were included in the study. 50.5% of the patients were male and the mean age was 61.8 ± 16.5 years. The age, gender, height, and weight of the patients were similar. 75.2% (331) of the tests were evaluated as successful. The most common errors in tests were early termination (84.1%), uncooperative patients (29%), and poor effort (22.4%). The types of errors were not different between the two periods. The median number of tests performed for each patient was six. The total number of spirometry tests performed were 262 and 178 for 2019 and 2021 (p= 0.011), but test success remained unchanged over the years (p= 0.513). There was no significant difference between the three operators and the test success (p= 0.909), which was similar for both periods. However, the number of tests performed until the successful maneuver varied significantly (p= 0.009), and fewer maneuvers were required before the pandemic. Conclusions: According to this study, the measures taken during the pandemic did not affect the quality of spirometry, but they did lead to more tests being done up until the successful maneuver was performed.

BACKGROUND: It was aimed to analyze the relationship between tuberculosis-related mortality and nitrous oxide emission levels in the world with the Environmental Kuznets Curve (EKC) Method. METHODS: WHO ICD-10 mortality list data and the World Bank Country Data (WBCD) were used between 1997 and 2017 for 12 countries. Cubic regression analysis was used for EKC Analysis. RESULTS: The difference between male and female deaths between 1996 and 1998 has increased sharply since 1999. Male deaths consistently occurred significantly more than female deaths. There was a significant and negative correlation between Nitrous oxide emissions (% change from 1990) and tuberculosis-related deaths, whereas there were significant and positive correlations between Nitrous oxide emissions in the energy sector (% of total) and tuberculosis-related deaths (p < 0.01). EKC analysis results showed that there is a U shaped between tuberculosis-related mortality and nitrous oxide emission levels in the world. DISCUSSION: Research results show that the relationship between nitrous oxide change and mortality is negative in the short term and positive in the long term. Therefore, although nitrous oxide gases cause respiratory diseases and mortality, it may be possible to transform a harmful environmental factor into a positive by developing devices or methods that will convert these gases into free radicals.

Background: Coronavirus disease 2019 (covid-19), which causes a pandemic in the world, has started to appear in turkey since march 2020. Healthcare workers are at the top of the groups most at risk for covid-19 infection, which can have a negative impact on psychological state. Objectives: It was aimed to evaluate anxiety and depression levels among healthcare workers. Methods: this cross-sectional study performed via an online survey in april 2020. Participants answered questions about sociodemographic features, personal views and experiences about covid-19 and the hospital anxiety and depression scale (hads). Results: A total of 300 healthcare workers,193 men and 107 women, participated in the survey. According to hads, 44.6% of participants scored above anxiety and 68.2% scored above depression cut-off points. Being younger than 50 and taking care of covid-19 patients in hospitals were independently associated with anxiety risk. Female gender, young age (less than 50) and having comorbidity were independent risk factors for depression. Conclusion: Healthcare workers were at high risk of anxiety and depression during covid-19 outbreak. For this reason, psychological support should be given, especially to the group with high risk.

INTRODUCTION: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), causing a global pandemic starting from December 2019, showed a course that resulted in serious mortality in the world. In order to understand SARSCoV-2 better, here we aimed to compare the similar and different characteristics of Influenza viruses occurring in the same season with SARS-CoV-2. MATERIALS AND METHODS: A total of 144 patients (31 patients with COVID-19, 62 patients with H1N1 influenza, and 51 patients with influenza B) were included in the study. Demographic findings, chronic diseases, laboratory values, chest x-ray, and chest CT findings of the patients were evaluated retrospectively. RESULT: Median age of the COVID-19 patients and rate of male patients were higher than other patient groups (55 years; p< 0.001) (61% male; p< 0.001). The most common chronic medical conditions were hypertension and diabetes. Platelet numbers and alanine aminotransferase values were significantly higher in COVID-19 patients. Radiologically, bilateral (74.2%) and nonspecific distribution (58.1%), ground-glass opacities with consolidation (51.6%), patchy image (25.8%), ground-glass opacities with interstitial changes (22.6%) and halo sign (22.6%) were quite evident than other groups in COVID-19 patients (p< 0.05). CONCLUSIONS: We suggest that due to the higher PLT values observed in COVID-19 patients, initiation of anticoagulant therapy should be considered in the early stage and routine follow-up with d-dimer and fibrinogen should be applied for suspected patients. Moreover, attention should be paid in terms of possible liver toxicity of the drugs to be used in treatment due the higher ALT values observed in COVID-19 patients. Since we did not detect SARS-CoV-2 and influenza viruses concurrently in the same patient, it may be helpful to focus on only one virus in a patient with symptoms, and radiographic differences can be used to differentiate COVID-19 from influenza.

BACKGROUND: After the first case of coronavirus disease 2019 (COVID-19) was reported in China in December 2019, it caused a global pandemic, including Turkey. OBJECTIVES: The aim of this study was to analyse the characteristics of hospitalised COVID-19 patients and assess the parameters related to severe pneumonia. METHODS: Included in the study were hospitalised COVID-19 patients with positive naso-oropharyngeal swabs. Patients' demographics, admission symptoms, laboratory and radiological findings were recorded retrospectively. RESULTS: Of 1013 patients, 583 were males (57.6%) and 430 were females (42.4%), with a mean age of 53.7 ± 17.9. More than half of the patients had at least one comorbidities, the most common of which were hypertension and diabetes mellitus. Cough (59.8%), fatigue (49.5%) and fever (41.2%) were the most common presenting symptoms. Of the hospitalised COVID-19 patients, 84.9% had pneumonia and 83.5% had typical radiological COVID-19 appearances (94.5%: ground-glass areas). The most common laboratory findings were high C-reactive protein (CRP) (73.6%) and lactate dehydrogenase (LDH) (46.2%) levels, as well as lymphopenia (30.1%). Severe pneumonia was present in 28.1% of COVID-19 patients. Multivariate logistic regression analysis indicated that advanced age, hypotension, anaemia and elevated CRP and LDH serum levels were independent risk factors for the severity of COVID-19 pneumonia (P = .011, .006, .017, .003 and .001, respectively). CONCLUSION: This study, as one of the first multicentre studies about characteristics of COVID-19 in Turkey, may guide about disease-related parameters and severity of pneumonia. Age, blood pressure, complete blood count and routine biochemical tests (including CRP and LDH) would appear to be important parameters for the evaluation of the severity of COVID-19 pneumonia.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has infected millions of people worlwide and caused a pandemic that is still ongoing. The virus can cause a disease named as COVID-19, which is composed of multi systemic manifestations with a pulmonary system predominance. As the time passes, we are dealing more and more with a wide variety of effects and complications of the disease in survivors as far as with concerns about the clinical outcome and the timeline of symptoms in different patients. Since the lungs are the most involved organs and the post-COVID prolonged and persistent effects are mainly related to the pulmonary system, it is crucial to define and predict the outcome and to determine the individuals that can progress to fibrosis and loss of function of lungs. This review summarizes the current literature regarding the pulmonary complications in post-COVID syndrome and the management of these conditions.

AIMS: This study aimed to investigate the clinical and chest computed tomography (CT) features associated with clinical parameters for coronavirus disease (COVID-19) in the capital of Turkey, Ankara. MATERIALS AND METHODS: Epidemiological, clinical features, laboratory findings and radiological characteristics of 1563 hospitalised patients with COVID-19 in Ankara were collected, reviewed and analysed in this study. The risk factors associated with disease severity were investigated. RESULTS: Non-severe (1214; 77.7%) and severe cases (349; 22.3%) were enrolled in the study. Compared with the non-severe group, the severe group were significantly older and had more comorbidities (ie, hypertension, diabetes mellitus, cardiovascular disease and chronic kidney disease). Smoking was more common in the severe group. Severe patients had higher respiratory rates and higher incidences of cough and dyspnoea compared with non-severe patients. Compared with the non-severe patients, the severe patients had increased C-reactive protein (CRP), procalcitonin, neutrophil to lymphocyte ratio (NLR) and CRP/albumin ratio and decreased albumin. The occurrence rates of consolidation, subpleural sparing, crazy-paving pattern, cavity, halo sign, reversed halo sign, air bronchogram, pleural thickening, micronodule, subpleural curvilinear line and multilobar and bilateral involvement in the CT finding of the severe patients were significantly higher than those of the non-severe patients. CONCLUSIONS: Many factors are related to the severity of COVID-19, which can help clinicians judge the severity of the patient and evaluate the prognosis. This cohort study revealed that male sex, age (≥55 years), patients with any comorbidities, especially those with cardiovascular disease, dyspnoea, increased CRP, D-dimer and NLR, and decreased lymphocyte count and CT findings of consolidation and multilobar involvement were predictors of severe COVID-19.

INTRODUCTION: In this retrospective study, the aim is to determine the sensitivity of maximum intensity projection (MIP) technique to 3 mm-thick axial sections in patients with small pulmonary nodules identified via examination using computed tomography (CT), and to identify whether this technique provides significant reduction in duration of nodule evaluation. MATERIALS AND METHODS: A total of 69 patients (339 nodules) who underwent thoracic tomography due to various complaints and in whom pulmonary nodules were identified as a result of the examination were included in the study. Their axial sections that are 3 mm-thick and MIP sections obtained in the axial plane were evaluated by two different radiologists at different times by keeping time. The dimensions and evaluation times of the nodules were recorded separately for each method. RESULT: Evaluation compatibility between the radiologists was found to be 86.8% and it was considered to be perfectly compatible. Sensitivity of the 1st radiologist in the detection of nodules with MIP was 81.4%, whereas the sensitivity of the 2nd radiologist was 83.4%. In the evaluation for the reporting periods, when the duration of evaluation of MIP images were compared with the gold standard, a statistically significant reduction was found in the reporting times of both radiologists (p< 0.01). CONCLUSIONS: It was found that utilization of MIP images as an alternative method to detect pulmonary modules reduces the duration of evaluation significantly and provides the ability to detect nodules with high sensitivity. According to these data, MIP imaging may be preferred as an adjunct method in the evaluation of lung nodules as it provides fast and reliable information besides classical axial sections.

OBJECTIVES: Since many similar mechanisms may play a role in the pathophysiology of sarcoidosis and atherosclerosis, the risk of subclinical atherosclerosis may be increased in patients with sarcoidosis. The aim of this study was to evaluate known markers of subclinical atherosclerosis, namely epicardial fat thickness (EFT) and carotid intima-media thickness (CIMT) in patients with sarcoidosis. MATERIALS AND METHODS: This cross-sectional study included a total of 183 subjects, including 94 patients with sarcoidosis (patient group) and a control group of 89 healthy individuals. Measurements of EFT and CIMT were taken from all subjects and recorded. The groups were compared, and differences were analyzed statistically. RESULTS: EFT was higher in patients than in control subjects (6.42±1.12 mm vs 7.13±1.41 mm, p<0.001). CIMT was higher in patients than in control subjects (0.51±0.02 mm vs 0.52±0.02 mm, p=0.003). CONCLUSION: EFT and CIMT were found to be higher in patients with sarcoidosis than in healthy people. These results indicate that the risk of subclinical atherosclerosis might be increased in these patients.
RESUMO
OBJECTIVES: COVID-19 is a great threat to the modern world and significant threat to immunocompromised patients, including patients with chronic renal failure. We evaluated COVID-19 incidence among our hemodialysis patients and investigated the most probable immune mechanisms against COVID-19. MATERIALS AND METHODS: Baskent University has 21 dialysis centers across Turkey, with 2420 patients on hemodialysis and 30 on peritoneal dialysis. Among these, we retrospectively evaluated 602 patients (257 female/345 male) with chronic renal failure receiving hemodialysis as renal replacement therapy; 7 patients (1.1%) were infected with SARS-CoV-2. We retrospectively collected patient demographic characteristics, clinical data, and immunological factors affecting the clinical course of the disease. We divided patients into groups and included 2 control groups (individuals with normal renal functions): group I included COVID-19-positive patients with normal renal function, group II included COVID-19-positive hemodialysis patients, group III included COVID-19-negative hemodialysis patients, and group IV included COVID-19-negative patients with normal renal function. Lymphocyte subsets in peripheral blood and typing of human leukocyte antigens were analyzed in all groups, with killer cell immunoglobulin like receptor genes analyzed only in COVID-19-positive patients and healthy controls. RESULTS: No deaths occurred among the 7 COVID-19-positive hemodialysis patients. Group I patients were significantly older than patients in groups II and III (P = .039, P = .030, respectively) but not significantly different from group IV (P = .060). Absolute counts of natural killer cells in healthy controls were higherthan in other groups (but not significantly). ActivatedT cells were significantly increased in both COVID-19-positive groups versus COVID-19-negative groups. Groups showed significant differences in C and DQ loci with respect to distribution of alleles in both HLA classes. CONCLUSIONS: Although immunocompromised patients are at greater risk for COVID-19, we found lower COVID-19 incidence in our hemodialysis patients, which should be further investigated in in vitro and molecular studies.

COVID-19 pneumonia has high mortality rates. The symptoms are undiagnostic, the results of viral nucleic acid detection method (PCR) can delay, so that chest computerized tomography is often key diagnostic test in patients with possible COVID-19 pneumonia. In this review, we discussed the main radiological findings of this infection.

OBJECTIVES: We evaluated the frequency and cause of acute respiratory failure in renal transplant recipients. MATERIALS AND METHODS: Our single-center retrospective observational study included consecutive renal transplant recipients who were admitted to an intensive care unit for acute respiratory failure between 2011 and 2017. Acute respiratory failure was defined as oxygen saturation < 92% or partial pressure of oxygen in arterial blood < 60 mm Hg on room air and/or requirement of noninvasive or invasive mechanical ventilation. RESULTS: Of 187 renal transplant recipients, 35 (18.71%) required intensive care unit admission; 11 of these patients (31.4%) were admitted to the intensive care unit with acute respiratory failure. Six of these patients (54.5%) had pneumonia and had shown infiltrates on chest radiography, which were shown in a minimum of 3 zones of the lung (2 with Klebsiella pneumonia, 1 with Acinetobacter species, 1 with Proteus mirabilis, 2 with no microorganisms). The other reasons for acute respiratory failure were cardiogenic pulmonary edema (2 patients), acute respiratory distress syndrome (2 patients, due to acute pancreatitis and acute cerebrovascular thromboembolism), and exacerbation of chronic obstructive pulmonary disease (1 patient). Six patients (54.5%) needed invasive mechanical ventilation because of pneumonia (3 patients), cardiogenic pulmonary edema (2 patients), and cerebrovascular thromboembolism (1 patient). Hemodialysis was administered in 5 patients (45%). Six of 11 patients died due to pneumonia (3 p atients), cardiogenic pulmonary edema (2 patients), and cerebrovascular thromboembolism (1 patient). Among the 5 survivors, 3 (60%) had recovered previous graft function. CONCLUSIONS: Acute respiratory failure is associated with high mortality and morbidity in renal transplant recipients. Main causes of acute respiratory failure were bacterial pneumonia and cardiogenic pulmonary edema in our study population. Extended chemoprophylaxis for bacterial and fungal infection and early intensive care unit admission of patients with acute respiratory failure may improve outcomes.

OBJECTIVES: Obesity is a risk factor defined in recent years for asthma. It is associated not only with asthma but also with many cardiovascular diseases. Visceral obesity is a more significant risk factor than general obesity in cardiovascular diseases. Although the association of visceral obesity with cardiovascular diseases is well known, the relationship in patients with asthma is not fully understood. The aim of the present study was to investigate whether there is a relationship between asthma and visceral fat by using epicardial fat thickness (EFT) measurement. MATERIALS AND METHODS: A total of 401 subjects (229 patients with persistent asthma and 172 controls) were enrolled in the study. In our study, EFT was measured, recorded by echocardiography, and was evaluated whether there was a statistical significant difference between the two groups. RESULTS: The mean EFT was 5.84±0.79 mm in the patient group and 5.71±0.93 mm in the control group. There was no statistically significant difference between the groups (p=0.145). Similarly, when we compared control and asthma severity subgroups, we did not find statistically significant differences (control group mean 5.71±0.93 mm, mild group mean 5.86±0.81 mm, moderate group mean 5.8±0.84 mm, and severe group mean 5.83±0.67 mm, p=0.505). CONCLUSION: In the present study, we observed that the EFT did not increase in patients with asthma compared with the normal population. Based on our results, we suggest that visceral obesity may not be a significant risk factor for asthma.
RESUMO
Invasive pulmonary aspergillosis is an infection seen in patients receiving intensive immunosuppressive regimens, such as transplant recipients. Some risk factors that increase the incidence of infection have been determined, and patients defined as having high risk are recommended to take antifungal prophylaxis and be monitored closely. Here, we present a liver transplant patient with mild respiratory symptoms and a normal chest radiography on day 26 posttransplant. However, he had acute renal failure and underwent hemodialysis, which are both defined to increase significantly the risk of aspergillosis. Although the radiographic scan was initially normal, thorax tomography and later bronchoscopy showed findings compatible with pulmonary aspergillosis, and the patient was started on antifungal treatment. The nonspecific mild symptoms and an initial normal radiology can make diagnosis of invasive fungal infections difficult; thus caution and close follow-up of high-risk patients should be performed.

OBJECTIVES: Pulmonary infections are a significant cause of morbidity and mortality in solid-organ transplant recipients despite enhanced facilities for perioperative care. The aim of this study was to evaluate the demographic characteristics, clinical course, and outcomes of renal transplant recipients with pneumonia. MATERIALS AND METHODS: The medical records of all renal transplant recipients from January 2010 to December 2014 were retrospectively reviewed, and patients diagnosed with pneumonia according to Centers for Disease Control and Prevention criteria were evaluated. Pneumonia was classified as community acquired or nosocomial. Patient demographics, microbiologic findings, need for intensive care/mechanical ventilation over the course of treatment, and information about clinical follow-up and mortality were all recorded. RESULTS: Eighteen (13.4%) of 134 renal transplant recipients had 25 pneumonia episodes within the study period. More than half (56%) of the pneumonia episodes developed within the first 6 months of transplant, whereas 44% developed after 6 months (all > 1 year). Eight cases (32%) were considered nosocomial pneumonia, and 17 (68%) were considered community-acquired pneumonia. Bacteria were the most common cause of pneumonia (28%), and fungi ranked second (8%). No viral or mycobacterial agents were detected. No patients required prolonged mechanical ventilation. No statistically significant difference was found in the need for intensive care or regarding mortality between patients with nosocomial and community-acquired pneumonia. Two patients (11%) died, and all remaining patients recovered. CONCLUSIONS: The present study confirmed that pneumonia after renal transplant is not a rare complication but a significant cause of morbidity. Long-term and close follow-up for pneumonia is necessary after renal transplant.

Hydrothorax occurs frequently in patients with endstage liver disease and usually requires drainage of pulmonary effusion during the hepatectomy phase of liver transplant. Reexpansion pulmonary edema is a rare but potentially fatal complication seen after rapid reexpansion of the collapsed lung following thoracentesis of pleural fluid or tube drainage of pneumothorax. This condition, which manifests with various degrees of clinical severity, is rarely reported following liver transplantation. Herein, we present a 62-year-old male patient who developed reexpansion pulmonary edema after drainage of massive pleural effusion, which caused a total collapse in the right hemithorax during liver transplant. Six hours after pleural fluid drainage, the patient developed a nonproductive cough, mild tachypnea, shortness of breath, and low oxygen saturation (88%). His chest radiograph showed diffuse heterogeneous opacities in the right hemithorax. Computed tomography of the thorax revealed consolidations containing air bronchograms and ground glass opacities in the parenchyma of the right lung; these findings did not extend to the periphery and were observed less frequently in the inferoposterior left lung. These symptoms and radiologic findings were diagnosed as reexpansion pulmonary edema. Complete clinical and radiologic improvements were achieved within 72 hours of mechanical ventilatory support.
