In this article, Early Career Task Force Group members of the Turkish Thoracic Society summarize the European Respiratory Society 2020 virtual congress. Current developments in the field of respiratory diseases were compiled with the addition of sessions specific to coronavirus disease 2019 this year. Almost all of the congress sessions were examined, and the important and striking results of the congress were highlighted. Congress sessions were attended by expert researchers, and the prominent messages of each session were highlighted in short summaries. They were then grouped under relevant titles and ranked in order of meaning and relation. It was finalized by a team of researchers.

Is the Perioperative Period No Longer a Problem for Adult Asthmatics under Control?-OPERA Study.

OBJECTIVES: Asthma is a global problem and chronic condition that persists through patient's entire life, during which the possibility of a surgical procedure is common. An accurate clinical and functional evaluation of respiratory functions and asthma control is needed in patients undergoing surgical procedures and requiring general anesthesia. The aim of this study was to disclose any possible relation between postoperative complications and some pre- and postoperative factors. MATERIALS AND METHODS: In this prospective cross-sectional study, randomly selected 111 asthmatic patients who presented to 10 different tertiary centers were included. The patients were evaluated at three different periods; any day between 1-7 days before surgery, and postoperative third and seventh to tenth days. RESULTS: Among the patients included in the study, 86 (77.5%) were women and mean age was 52.2±13.8 years. General anesthesia was the most common anesthesia type (89.2%), and 33.3% of patients had had a thoracoabdominal surgery. There was a statistically significant difference between pre- and postoperative third-day values, including ACT scores (22.2±3.16 and 21.59±3.84, respectively; p<0.001); forced expiratory volume during the first second (84.92±19.12 and 78.26±18.47, respectively; p<0.001); peak flow rate (79.51±21.12 and 70.01±19.72, respectively; p<0.001); and SaO2 (96.95±1.82 and 95.8±3.32, respectively; p<0.001). Bronchospasm and pain were the most common complications during the postoperative period. CONCLUSION: Controlled asthma under treatment steps 1-2-3 does not cause any serious postoperative pulmonary complications (PPCs). Therefore, achieving an optimal control level of asthma during the preoperative period must be considered the "gold standard" to reduce the risk of PPCs in asthmatic patients.

What We Learned about COVID-19 So Far? Notes from Underground.

The novel coronavirus pandemic poses a major global threat to public health. Our knowledge concerning every aspect of COVID-19 is evolving rapidly, given the increasing data from all over the world. In this narrative review, the Turkish Thoracic Society Early Career Taskforce members aimed to provide a summary on recent literature regarding epidemiology, clinical findings, diagnosis, treatment, prevention, and control of COVID-19. Studies revealed that the genetic sequence of the novel coronavirus showed significant identity to SARS-CoV and MERS-CoV. Angiotensin-converting enzyme 2 receptor is an important target of the SARS-CoV-2 while entering an organism. Smokers were more likely to develop the disease and have a higher risk for ICU admission. The mean incubation period was 6.4 days, whereas asymptomatic transmission was reported up to 25 days after infection. Fever and cough were the most common symptoms, and cardiovascular diseases and hypertension were reported to be the most common comorbidities among patients. Clinical manifestations range from asymptomatic and mild disease to severe acute respiratory distress syndrome. Several patients showed typical symptoms and radiological changes with negative RT-PCR but positive IgG and IgM antibodies. Although radiological findings may vary, bilateral, peripherally distributed, ground-glass opacities were typical of COVID-19. Poor prognosis was associated with older age, higher Sequential Organ Failure Assessment score, and high D-dimer level. Chloroquine was found to be effective in reducing viral replication in vitro. Likewise, protease inhibitors, including lopinavir/ritonavir, favipiravir, and nucleoside analogue remdesivir were proposed to be the potential drug candidates in COVID-19 management. Despite these efforts, we still have much to learn regarding the transmission, treatment, and prevention of COVID-19.

Frequency of Exacerbations and Hospitalizations in COPD Patients Who Continue to Smoke.

We evaluated the frequency of exacerbations and hospitalizations in chronic obstructive pulmonary disease (COPD) patients who continue to smoke.: We retrospectively analyzed the medical records of the COPD patients treated in Chest Diseases Clinic of Kocaeli University School of Medicine in 2007-2013. Their demographic characteristics, smoking status (non-smoker, current smoker, ex-smoker), Charlson Comorbidity Index (CCI), and history of COPD exacerbation and hospitalizations were evaluated. The cases of 120 patients (11 females, 9.2%; 109 males, 90.8%) were analyzed. Sixteen (13.3%) of the patients were current smokers, and 104 patients were ex-smokers (n=99) or non-smokers (n=5). The mean age was 69.7±7.9 years in the ex-smokers and 62.94±6.8 years in the current smokers. There were no significant differences between the current and ex-smokers regarding smoking history, FEV1 value, frequencies of exacerbations and hospitalization per year, or duration of follow-up. The initial stage of the COPD and the frequency of exacerbations were significantly correlated (p=0.003). The CCI values were significantly higher in the ex-smokers compared to current smokers (p=0.02). A correlation analysis of age, hospitalization and CCI revealed that age was significantly correlated with the hospitalization rate (p=0.02). Older age and the presence of comorbidities in ex-smokers might explain the similar rates of exacerbation and hospitalization between these current and ex-smokers.

The effect of positive airway pressure therapy on neurocognitive functions, depression and anxiety in obesity hypoventilation syndrome.

BACKGROUND: The aim of this study is to evaluate the presence of neurocognitive dysfunctions, depression and anxiety and the effect of positive airway pressure (PAP) therapy on these alterations in Obesity Hypoventilation Syndrome (OHS) patients. METHODS: Ten healthy normal and obese controls, 10 OHS and 10 OSAS patients were included in the study. Short form-36, Beck Depression Scale and State-Trade Anxiety Inventory (STAI 1-2) were performed. Wisconsin Card Sorting Test (WCST), Montreal Cognitive Assessment Scale (MOCA), Enhanced Cued Recall (ECR) and Mini Mental Test (MMT) were used for neurocognitive evaluation. All tests were repeated after one night PAP therapy in OHS and OSAS groups. RESULTS: OHS patients had the lowest scores of physical (PF) and social functioning (SF) in SF-36. The total number of persistent errors and incorrect answers were the highest in OHS group in WCST. The scores of MOCA, ECR and MMT were lower; depression and anxiety scores were higher in OHS group than in controls (p = 0,00). There was a significant increase in the completed categories in OHS after PAP therapy (p = 0,03). There were also significant increases in MOCA, ECR and MMT scores and significant decreases in depression and anxiety scores with respect to PAP therapy. CONCLUSIONS: Cognitive dysfunction, depression and anxiety are important under-recognized comorbidities in OHS. It is suggested that short term PAP therapy had positive effects on neurocognitive functions, depression and anxiety but further multicentre, prospective studies with large number of cases are needed to evaluate the effect of long term PAP therapy on these parameters.

Endobronchial Tuberculosis Mimicking Asthma.

Endobronchial tuberculosis (EBTB) is defined as tuberculosis infection of the tracheobronchial tree with microbial and histopathological evidence. The clinical symptoms of the diseases are nonspecific. Chronic cough is the major symptom of the disease. The diagnosis is often delayed due to its nonspecific presentation and misdiagnosed as bronchial asthma. This case is presented to recall the notion that the endobronchial tuberculosis can mimic asthma and the importance of bronchoscopic evaluation in a patient with chronic cough and treatment resistant asthma.
