- Abstract
Introduction: Partial carbondioxide pressure of the arterial blood (PaCO2) is used to evaluate alveolar ventilation. Transcutaneous carbon dioxide pressure (TcCO2) monitoring has been developed as a non-invasive (NIV) alternative to arterial blood gas analysis (ABG). Studies have shown that decreased tissue perfusion leads to increased carbondioxide (CO2). The use of transcutaneous capnometry may be unreliable in patients with perfusion abnormalities. In this study, we aimed to evaluate the relation between TcCO2-PaCO2 and lactate level which is recognized as a marker of hypoperfusion., Materials and Methods: In this prospective cohort study in critical care patients with hypercapnic respiratory failure (PaCO2 ≥45 mmHg) who received NIV between April 2019 and January 2020 in the intensive care unit were enrolled in the study. Patients' simultaneously measured TcCO2 and PaCO2 values of hypercapnic patients were recorded. Each paired measurement was categorized into two groups; normal lactate (<2 mmol/L) and increased lactate (≥2 mmol/L)., Result: A total of 116 paired TcCO2 and PaCO2 measurements of 29 patients were recorded. Bland-Altman analysis showed the mean bias between the TcCO2 and PaCO2 and 95% limits of agreement (LOA) in all measurements (1.75 mmHg 95% LOA -3.67 to 7.17); in the normal lactate group (0.66 mmHg 95% LOA -1.71 to 3.03); and in the increased lactate group (5.17 mmHg 95% LOA -1.63 to 11.97). The analysis showed a correlation between lactate level and the difference between TcCO2 and PaCO2 (r= 0.79, p< 0.001) and a negative correlation between mean blood pressure and the difference between TcCO2 and PaCO2 (r= -0.54, p= 0.001). Multiple regression analysis results showed that lactate level was independently associated with increased differences between TcCO2 and PaCO2 (Beta= 0.875, p< 0.001)., Conclusions: TcCO2 monitoring may not be reliable in patients with increased lactate levels. TcCO2 levels should be checked by ABG analysis in these patients.

- Abstract
Introduction: Lung cancer is the most common solid organ malignancy requiring intensive care unit (ICU) admission. For many years, lung cancer patients were not considered in the priority patient category for admission to ICU because of their high mortality rate and poor response to therapy. Considering the developments in treatment modalities, we aimed to reevaluate the prognosis of patients with lung cancer in the ICU., Materials and Methods: Patients characteristics, date of diagnosis, the reason for ICU admission, the stage of cancer, histopathological type, history of chemotherapy, radiotherapy, or surgery for cancer, and APACHE-II and Charlson comorbidity index (CCI) were recorded retrospectively., Result: A total of 100 patients had a mean age of 69.7 ± 9.0 years. Among these patients, 18% had small cell lung cancer, while 82% had non-small cell lung cancer. The in-hospital mortality rate was 69% for all patients, while among those discharged from the ICU, the first 6-month mortality rate was 58.1%. The median survival time was 8.2 months. Advanced age, the need for mechanical ventilation, the need for vasopressors, a high APACHE -II, and the CCI all reduced survival in multivariate analysis, whereas chemotherapy and surgical history improved survival., Conclusions: Patients admitted to the ICU with lung cancer continue to experience a high mortality rate. However, identifying the factors that are associated with survival can be crucial in establishing care plans and prioritizing ICU admission for further therapy.

- Abstract
Introduction: Although thorax ultrasound has been used to diagnose pneumonia in recent years, the role of ultrasonic diaphragm evaluation in the prognosis of pneumonia is unknown. This study aimed to assess the impact of diaphragmatic excursion (Dex) measured by ultrasound on the prognosis of severe pneumonia in critical care patients., Materials and Methods: We prospectively recruited patients with severe pneumonia who were admitted to the intensive care unit (ICU) between January 2019 and July 2021. Patients' Dex values, vital signs, clinical features, laboratory parameters, APACHE-II scores on the first admission day of ICU, mortality and respiratory support status at follow-up were recorded., Result: There were 39 patients enrolled in the study. Mean Dex of the study patients was 30.66 ± 12.17 mm. Mean Dex was significantly lower in deceased patients than survivors (18.37 ± 8.12 vs 34.90 ± 10.36 p< 0.001). Dex was lower in patients who required invasive mechanical ventilation than those not (24.90 ± 10.93 vs 34.26 ± 11.70, p= 0.017). The cut-off value of Dex was found 19.0 mm for significantly predicted (p≤ 0.001) survival with the sensitivity of 96.6% and specificity of 70%. Among the study group, diaphragm excursion was negatively correlated with APACHE-II score (r= -0.688, p≤ 0.001) and respiratory rate (r= -0.531, p= 0.001)., Conclusions: Dex measured on the day of ICU admission can be used to evaluate the prognosis of patients with severe pneumonia.

- Abstract
Introduction: Acute pulmonary thromboembolism (PTE) is a common cause of cardiovascular mortality. Right ventricular (RV) dysfunction is the most important cause of mortality. Computed Tomography Pulmonary Angiography (CTPA) can detect right ventricular enlargement which is an indicator of RV dysfunction at the time of diagnosis. This study aimed to determine the parameters indicating RV dysfunction in CTPA and correlation of early mortality findings., Materials and Methods: In this retrospective study, electronic files of patients diagnosed PTE with CTPA between January 2012 and December 2017 were evaluated. Measurements of heart chambers, IVC reflux, and IVS morphology were calculated. In-hospital mortality of the patients after acute PTE diagnosis was evaluated., Result: There were 206 eligible patients. Among the evaluated radiological parameters, right atrium (RA) size (p= 0.002), PA size (p= 0.003), Ao size (p= 0.006), and the presence of IVC reflux (p= 0.001) were associated with mortality. No significant relationship was found between RV/LV ≥1 and mortality (p= 0.908). All patients with PTE-related mortality had RV/LV ratio ≥1 in CTPA and had IVC reflux. Patients with an RV/LV ratio of ≥1 had statistically significantly higher troponin levels (p= 0.004) and IVC reflux (p= 0.025) compared to patients with an RV/LV ratio of <1., Conclusions: In conclusion, RV/LV ratio should be evaluated together with cardiac biomarkers to define mortality risk.

- Abstract
Introduction: The patients in the intensive care unit have a higher risk of infections because of the poor general condition of these patients and the frequent application of invasive procedures with longer hospitalization length. Also, this group of patients tend to have resistant infections due to empirically widespread and uncontrolled use of broad-spectrum antibiotics. Hence, data are needed to determine appropriate empirical antibiotic therapy in intensive care patients. In this study, it was aimed to assess the distribution of microorganisms and antibiotic resistance profile from the samples taken from the patients in the intensive care unit., Materials and Methods: Patients who were hospitalized in Ankara University Faculty of Medicine Chest Diseases Intensive Care Unit for more than 24 hours between December 2016 and December 2017 were included in our study. Demographic characteristics, comorbid diseases, clinical findings, results of sputum, tracheal aspirate, blood, urine, gaita and pus culture samples and antibiotic susceptibility test results were recorded prospectively., Result: A total of 287 patients, 150 males and 137 females, were included in the study. The mean age of all patients was 69.96 ± 14.4 years. Two hundred twenty-three positive cultures were detected in 1053 samples taken from 287 patients. Gram-negative bacilli constituted 55.1% of the 223 positive cultures. The most common microorganisms were Acinetobacter (16.6%), Staphylococcus (14.8%) and Klebsiella (10.8%). Colistin resistance was found to be 8.3% in the Acinetobacter strains and resistance rates of 97-100% were observed to other antibiotic groups. Thirty-three staphylococcus were isolated, 17 were S. aureus and 16 were coagulase-negative Staphylococcus. While 29.4% of S. aureus were resistant to methicillin (MRSA), vancomycin resistance was not detected. Meanwhile, the MRSA ratio was 62.5%, there was no vancomycin resistance among the coagulase-negative Staphylococcus. Klebsiella was the third most common microorganism and beta-lactamase producing Klebsiella strain was 62.5%. Gentamycin was found to be the most susceptible antibiotic in Klebsiella strains with a resistance rate of 20.8%. Pseudomonas aeruginosa constituted 9.4% of the cultures. While the resistance to colistin was not detected, resistance to piperacillin/tazobactam 42.8%, tobramycin, imipenem and meropenem 50% and ceftazidime 61.9%. The duration of hospitalization in patients with Acinetobacter isolated (23 [10-34] days vs 12.5 [5-24] days, p= 0.011) and the mortality rate (62.5% vs 37.5%, p= 0.008) were significantly higher than those who were not Acinetobacter isolated., Conclusions: In conclusion, gram-negative bacilli constitute the majority of the patients in intensive care unit. Acinetobacter, the most common microorganism, has a high resistance rate and has been associated with prolonged hospitalization and mortality.

- Abstract
Coronavirus disease 2019 (COVID-19) has been demonstrated to be the cause of emerging atypical pneumonia. In patients with tracheostomy, coronavirus hypothetically coexists with well-known bacterial agents. A 61-year-old male patient with tracheostomy was admitted to the hospital with dyspnea, fever and increased tracheal secretions. Laboratory findings revealed lymphopenia and elevated C-reactive protein and procalcitonin levels. Chest computed tomography showed consolidation areas and ground-glass opacities more prominent in subpleural areas. Although; two consecutive RT-PCR analyses of combined nasopharengeal/oropharengeal swabs were found to be negative for SARS-CoV-2 RNA, positivity was reported for endotracheal aspirate (ETA) sample. Significant growth of Pseudomonas aeruginosa and Stenotrophomonas maltophilia was detected in the bacterial culture of ETA sample. In conclusion, clinical samples for SARS-CoV-2 should be obtained through the lower respiratory tract, if possible and if upper airway samples are negative. To the best our knowledge, our paper is the first report of the patient with tracheostomy who was treated successfully for COVID-19.

- Abstract
Prone positioning is a well-known supportive maneuver to improve oxygenation for patients with moderate to severe acute respiratory distress syndrome (ARDS). Although this technique is usually performed to sedated patients on invasive mechanical ventilation, it has been used in non-intubated patients frequently during the coronavirus diseases-2019 (COVID-19) pandemic. Favorable outcomes have been reported mainly in combining the prone positioning with high flow nasal cannula (HFNC) or non-invasive ventilation (NIV). Due to limited data, a standard approach for the awake prone positioning has not yet been defined. In this manuscript, we reviewed the literature data about prone positioning in non-intubated patients with COVID-19. According to available literature data, we concluded that prone positioning in non-intubated COVID-19 patients may improve oxygenation and prevent the need for invasive mechanical ventilation. But the efficacy is still controversial in the early stage of the disease due to pulmonary mechanics. Further studies are needed to the defined optimal approach of awake prone positioning in COVID-19 patients with hypoxemic respiratory failure.

- Abstract
In recent years, high flow nasal cannula (HFNC) is a respiratory support system that has become prominent in the treatment of respiratory failure. HFNC provides higher concentration and flow of oxygen, resulting in decreasing anatomic dead space by preventing rebreathing and ensure positive end-expiratory. However, in COVID-19, the usage of HFNC is much controversial due to concerns about the benefits and risk of aerosol-dispersion. Considering the debates about the use of HFNC, we reviewed the literature related to the usage of HFNC in COVID-19. The available reports suggest that HFNC provides high concentrations of oxygen to the patients, who can not reach with conventional devices. HFNC can reduce the requiring of intubation in patients with COVID-19, and it can decrease the length of intensive care unit stay, and complications related to mechanical ventilation. Also HFNC can in achieving apneic oxygenation in patients during airway management. Besides that, the use of high-flow oxygen cannulas can produce aerosols. So, HFNC treatment should be carried out in a negative pressure room; when it is not possible, devices should be undertaken in a single room.

- Abstract
Introduction: Sleep quality is known to be associated with the distressing symptoms of cancer. The purpose of this study was to analyze the impact of cancer symptoms on insomnia and the prevalence of sleep-related problems reported by the patients with lung cancer in Turkey., Materials and Methods: Assesment of Palliative Care in Lung Cancer in Turkey (ASPECT) study, a prospective multicenter study conducted in Turkey with the participation of 26 centers and included all patients with lung cancer, was re-evaluated in terms of sleep problems, insomnia and possible association with the cancer symptoms. Demographic characteristics of patients and information about disease were recorded for each patient by physicians via face-to-face interviews, and using hospital records. Patients who have difficulty initiating or maintaining sleep (DIMS) is associated with daytime sleepiness/fatigue were diagnosed as having insomnia. Daytime sleepiness, fatigue and lung cancer symptoms were recorded and graded using the Edmonton Symptom Assessment Scale., Result: Among 1245 cases, 48.4% reported DIMS, 60.8% reported daytime sleepiness and 82.1% reported fatigue. The prevalence of insomnia was 44.7%. Female gender, patients with stage 3-4 disease, patients with metastases, with comorbidities, and with weight loss > 5 kg had higher rates of insomnia. Also, patients with insomnia had significantly higher rates of pain, nausea, dyspnea, and anxiety. Multivariate logistic regression analysis showed that patients with moderate to severe pain and dyspnea and severe anxiety had 2-3 times higher rates of insomnia., Conclusions: In conclusion, our results showed a clear association between sleep disturbances and cancer symptoms. Because of that, adequate symptom control is essential to maintain sleep quality in patients with lung cancer.

- Abstract
Pleural empyema is a rare and serious complication of pneumonia. Although it is frequently seen in children, there are only a few reports about pleural empyema in newborn infants. Here we report a case of early onset neonatal pneumonia complicated with pleural empyema. The causal microorganism was group A beta-hemolytic streptococci (GAS or Streptococcus pyogenes) presumably originating from the mother, who had a puerperal infection. The mother had fever, pelvic pain, and abnormal vaginal discharge two days after delivery and subsequent increase in the antistreptolysin O titer, suggesting streptococcus infection. The patient was successfully treated by pleural drainage in addition to synergistic antimicrobial therapy.

- Abstract
Lung cancer in women is increasing in worldwide. This process beginning with the difference on the susceptibility of lung cancer in women smokers may be different from men in the prognosis. In this study, it was aimed to evaluate the clinical features, and prognostic factors of female patients with lung cancer diagnosed between January 2000-December 2005. The data of 109 patients data was evaluated. The mean age was 59.40 +/- 11.56 and 17 (15.6%) patients were smokers. In 20 patients (18.3%) having a family history of cancer, 55% of them had a relative with lung cancer. In admission, cough (81.7%), dyspnea (78.9%), chest pain (40.3%) were the most frequent presenting symptoms. The most common site of tumoral lesion in bronchoscopy were right upper lobe (16.5%). In the study group histopathological diagnosis were as follows; adenocarcinoma (44.9%), small cell lung cancer (SCLC) (19.3%), squamous cell (10.1%), non-small cell lung cancer (NSCLC) --undefined (22.0%), carsinoid tumors (2.8%), in non-smokers adenocarcinoma was significantly higher than smokers (44.9%/17.7%) (p< 0.001). 61.9% of NSCLC patients and 57.1% of SCLC patients had a stage IV disease at the initial evaluation. The most common sites of metastasis were bone (28.4%), liver (22.9%), and brain (11.9%), there were multiple metastasis in 10 patients. Median survival time was found as 288 days. In univariate analysis, comorbidity, primary tumor stage, bone metastasis, advanced disease stage, ECOG performance score >or= 2 and supportive care alone were poor prognostic factors. In multivariate analysis, poor performance status (p= 0.003), advanced disease stage (p= 0.002) and bone metastasis (p= 0.04) were negatively related to survival. In women, the definition of the clinical features, disease course and survival related factors may contribute to our future treatment approaches based on our national data.
