Challenges and perspectives of tobacco cessation in special groups of patients and populations.

During the first 2 years of the coronavirus disease 2019 pandemic, health systems worldwide were put under extreme pressure, and healthcare professionals had to manage unprecedented health crises as well as provide healthcare services to an increased number of patients. Therefore, public health policies with respect to smoking and education of the general population regarding the harmful effects of active and second-hand smoking may not have received adequate attention during this period. More specifically, certain subpopulations suffering from chronic diseases may not have received adequate information about the effects of smoking on the course and outcome of their disease; high-level, evidence-based pharmaceutical therapies; and the potential for follow-up. However, adequate education and awareness regarding short- and long-term health benefits from smoking cessation for the general population as well as special subgroups remains of utmost importance. Healthcare professionals should understand that it is only through high-quality evidence and results from independent studies that they will be able to provide their expertise and scientific knowledge concerning newer tobacco products and their effects on human health.

Management of COVID-19 Patients in the Emergency Department.

COVID-19 is an emerging disease of global public health concern. As the pandemic overwhelmed emergency departments (EDs), a restructuring of emergency care delivery became necessary in many hospitals. Furthermore, with more than 2000 papers being published each week, keeping up with ever-changing information has proven to be difficult for emergency physicians. The aim of the present review is to provide emergency physician with a summary of the current literature regarding the management of COVID-19 patients in the emergency department.

From Recession to Depression? Prevalence and Correlates of Depression, Anxiety, Traumatic Stress and Burnout in Healthcare Workers during the COVID-19 Pandemic in Greece: A Multi-Center, Cross-Sectional Study.

The COVID-19 pandemic has the potential to adversely affect the mental health of healthcare workers (HCWs). The public healthcare system in Greece was already facing serious challenges at the outset of the outbreak following years of austerity and an escalating refugee crisis. This multi-center, cross-sectional study aims to assess the levels and associated risk factors of anxiety, depression, traumatic stress and burnout of frontline staff in Greece. A total of 464 self-selected HCWs in six reference hospitals completed a questionnaire comprising sociodemographic and work-related information and validated psychometric scales. The proportion of HCWs with symptoms of moderate/severe depression, anxiety and traumatic stress were 30%, 25% and 33%, respectively. Burnout levels were particularly high with 65% of respondents scoring moderate/severe in emotional exhaustion, 92% severe in depersonalization and 51% low/moderate in personal accomplishment. Predictive factors of adverse psychological outcomes included fear, perceived stress, risk of infection, lack of protective equipment and low social support. The psychological burden associated with COVID-19 in healthcare professionals in Greece is considerable, with more than half experiencing at least mild mental health difficulties. Findings signal the need for immediate organizational and individually tailored interventions to enhance resilience and support wellbeing under pandemic conditions.

Device use errors among patients with asthma and COPD and the role of training: a real-life study.

Background and objectives: Administration of inhaled medication for asthma and COPD is often difficult and incorrect device use is associated with unfavorable outcomes. We aimed to evaluate device use errors in asthma and COPD patients and to associate incorrect use with the patient's characteristics and medical history.Methods: Demographics and medical history were recorded. The use of each prescribed device was evaluated according to predefined steps.Results: 607 patients (49.9% male, median age (IQR) 63 (51, 70) years performed 663 demonstrations (56 patients were using 2 different types of devices). 51.4% were treated for asthma and 48.6% for COPD. 79.6% of demonstrations were performed using DPIs. Errors were documented on 41.2% of demonstrations and were associated with the type of device, p < 0.001. Elderly patients were less frequently using their devices correctly compared to younger patients, 50.8% vs 62.2%, respectively, p = 0.007. Correct demonstrations were more among asthmatics compared to COPD patients 63.1% vs 54.5%, p = 0.024. Incorrect use was associated with more acute exacerbations in the preceding year [median(IQR), 1(0, 2) vs 1(0, 1)], for incorrect and correct use, respectively, p < 0.001. Upon demonstration, 15.5% of patients have never been trained (i.e., undergone actual demonstrations and observation while using their device) by anyone. Errors occurred more frequently among patients who reported not to be trained compared to those who were trained, 67.0% vs 14.6%, respectively, p < 0.001. The commonest error was associated with the inspiration maneuver and accounted for the 48.3% of errors in the DPIs and 53.0% of errors in the MDIs.Conclusion: Device use errors are common and associated with unfavorable outcomes. Trained patients were more likely to use the device correctly.

Critical analysis of the utility of initial pleural aspiration in the diagnosis and management of suspected malignant pleural effusion.

INTRODUCTION: Current guidelines recommend an initial pleural aspiration in the investigation and management of suspected malignant pleural effusions (MPEs) with the aim of establishing a diagnosis, identifying non-expansile lung (NEL) and, at times, providing a therapeutic procedure. A wealth of research has been published since the guidelines suggesting that results and outcomes from an aspiration may not always provide sufficient information to guide management. It is important to establish the validity of these findings in a 'real world' population. METHODS: A retrospective analysis was conducted of all patients who underwent pleural fluid (PF) sampling, in a single centre, over 3 years to determine the utility of the initial aspiration. RESULTS: A diagnosis of MPE was confirmed in 230/998 (23%) cases, a further 95/998 (9.5%) were presumed to represent MPE. Transudative biochemistry was found in 3% of cases of confirmed MPE. Positive PF cytology was only sufficient to guide management in 45/140 (32%) cases. Evidence of pleural thickening on CT was associated with both negative cytology (χ2 1df=26.27, p<0.001) and insufficient samples (χ2 1df=10.39, p=0.001). In NEL 44.4% of patients did not require further procedures after pleurodesis compared with 72.7% of those with expansile lung (χ2 1df=5.49, p=0.019). In patients who required a combined diagnostic and therapeutic aspiration 106/113 (93.8%) required further pleural procedures. CONCLUSIONS: An initial pleural aspiration does not achieve either definitive diagnosis or therapy in the majority of patients. A new pathway prioritising symptom management while reducing procedures should be considered.

Chest Drain Fall-Out Rate According to Suturing Practices: A Retrospective Direct Comparison.

BACKGROUND: Chest drains often become displaced and require replacement, adding unnecessary risks to patients. Simple measures such as suturing of the drain may reduce fall-out rates; however, there is no direct data to demonstrate this and no standardized recommended practice that is evidence based. OBJECTIVES: The study aimed to analyze the rate of chest drain fall out according to suturing practice. METHODS: Retrospective analysis of all chest drain insertions (radiology and pleural teams) in 2015-2016. Details of chest drain fall out were collected from patient electronic records. Drain "fall out" was pre-hoc defined as the drain tip becoming dislodged outside the pleural cavity unintentionally before a clinical decision was taken to remove the drain. RESULTS: A total of 369 chest drains were inserted: sutured (n = 106, 28.7%; 44 male [41.5%], median age 74 [interquartile range (IQR) 21] years), and unsutured (n = 263, 71.3%; 139 male [52.9%], median age 68 [IQR 21] years). Of the sutured drains, 7 (6.6%) fell out after a mean of 3.3 days (SD 2.6) compared to 39 (14.8%; p = 0.04) unsutured drains falling out after a mean of 2.7 days (SD 2.0; p = 0.8). CONCLUSIONS: Within the limits of this retrospective analysis, these results -suggest that suturing of drains is associated with lower fall-out rates.

The role of non-invasive modalities for assessing inflammation in patients with non-cystic fibrosis bronchiectasis.

INTRODUCTION: Bronchiectasis is a heterogeneous entity, taking into account clinical characteristics, inflammatory response, effectiveness of treatment and frequency of exacerbations. In stable state non-cystic fibrosis (non-CF) bronchiectasis, little is known about non-invasive techniques used for evaluating airway inflammation in obstructive airway diseases. OBJECTIVES: We sought to evaluate the associations between induced sputum and clinical/radiologic characteristics, and the differences between biomarkers expressing Th1 and Th2 response in patients with non-CF bronchiectasis and to compare our findings with a previously studied population of patients with asthma and COPD. METHODS: We evaluated prospectively collected data from subjects with bronchiectasis. Comparisons were made between clinical, radiographic and physiologic characteristics, as well as induced sputum markers using appropriate statistical tools. We compared the levels of sputum markers with those of a previously studied cohort of asthma and COPD patients. RESULTS: We enrolled 40 subjects (21men, mean age 63.5yrs) with bronchiectasis. Fifteen subjects (37.5%) had a neutrophilic phenotype, 7 (17.5%) had an eosinophilic phenotype, 3 (12.5%) had a mixed neutrophilic-eosinophilic phenotype and 15 (37.5%) had a paucigranulocytic phenotype. Subjects with sputum neutrophilia had more severe bronchiectasis in HRCT and higher levels of IL-8 in sputum, whereas subjects with eosinophilia had higher levels of FeNO, greater bronchodilator reversibility and higher sputum IL-13. Sputum IL-8 levels were higher in subjects exhibiting frequent exacerbations and correlated with neutrophils in sputum (r=0.799), the extent of bronchiectasis in HRCT (r=0.765) and post-bronchodilator FEV1 (r=-0.416). Sputum IL-13 levels correlated with sputum eosinophils (r=0.656) and bronchodilator reversibility (r=0.441). Neutrophilic bronchiectasis exhibited comparable IL-8 levels to COPD, whereas eosinophilic bronchiectasis showed significantly lower IL-13 levels compared to asthma. CONCLUSIONS: Sputum cell counts and IL-8 and IL-13 correlate with distinct clinical and functional measurements of disease severity and therefore may have a role for non-invasively assessing inflammation in non-cystic fibrosis bronchiectasis.

Acute effects of short term use of ecigarettes on Airways Physiology and Respiratory Symptoms in Smokers with and without Airway Obstructive Diseases and in Healthy non smokers.

BACKGROUND: Although the use of e-cigarettes is increasing worldwide, their short and long-term effects remain undefined. We aimed to study the acute effect of short-term use of e-cigarettes containing nicotine on lung function and respiratory symptoms in smokers with airways obstructive disease (COPD, asthma), "healthy" smokers, and healthy never smokers. METHODS: Respiratory symptoms, vital signs, exhaled NO, airway temperature, airway resistance (Raw), specific airway conductance (sGaw) and single nitrogen breath test were assessed before and immediately after short term use of an e-cigarette containing 11mg of nicotine among adults with COPD, asthma, "healthy" smokers, and never-smokers. The effect of the use of nicotine-free e-cigarettes among "healthy" never smokers was also studied. RESULTS: The majority of participants reported acute cough. Short term use of nicotine e-cigarettes was associated: a) with increased heart rate in all subjects except in the COPD group, b) decreased oxygen saturation in "healthy" and COPD smokers, c) increased Raw in asthmatic smokers, "healthy" smokers, and healthy never smokers, d) decreased sGaw in healthy subjects, and e) changed slope of phase III curve in asthmatic smokers. Short-term use of nicotine-free e-cigarettes increased Raw and decreased sGaw among healthy never smokers. CONCLUSIONS: Short-term use of an e-cigarette has acute effects on airways physiology and respiratory symptoms in COPD smokers, asthmatic smokers, "healthy" smokers and healthy never smokers. E-cigarette use was associated with effects in "healthy" never smokers irrespectively of nicotine concentration. More studies are needed to investigate both short and long-term effects of e-cigarette use.

Distribution of nontuberculous mycobacteria in treated patients with pulmonary disease in Greece - relation to microbiological data.

AIMS: The aim was to assess the distribution of nontuberculous mycobacteria (NTM) in treated patients with pulmonary disease (PD) in Greece. PATIENTS & METHODS: Patients treated for NTM PD at the two largest chest diseases hospitals in Greece, in the period 1990-2013 were investigated. For the years 2005-2013 data on NTM isolation frequency were recorded. RESULTS: M. avium complex (MAC) was the predominant cause of NTM PD disease followed by M. kansasii and rapid growing mycobacteria (RGM). The pathogenicity of RGM was significantly lower than this of MAC and M. kansasii. An increase was observed in the percentage of isolated NTM species that were considered clinically significant over the study period. CONCLUSIONS: The increasing number of NTM PD in Greece is a consequence of their isolation being more frequently considered as clinically relevant.

Prediction of hospitalization stay in COPD exacerbations: the AECOPD-F score.

BACKGROUND: Hospital admissions for COPD exacerbations account for 70% of total costs of COPD treatment, and the duration of hospital stay is directly related to this cost. The aim of this study was to investigate possible associations of demographic, clinical, laboratory, and functional parameters with stay of subjects admitted for COPD exacerbations and to provide a score for the prediction of the need for prolonged hospitalization. METHODS: We included 164 consecutive subjects admitted to 2 respiratory medicine departments of 2 tertiary hospitals for a COPD exacerbation, and we evaluated laboratory, clinical, and functional parameters possibly related to the duration of hospital stay. RESULTS: Seven parameters evaluated on subject admission (Antonisen type of exacerbation, number of Exacerbations in the previous year, Charlson index of comorbidities, Oxygenation, Partial pressure of P(aCO2) in arterial blood gases, Dyspnea according to the Borg dyspnea scale, and history of chronic respiratory Failure) were able to predict stay and were included in a simple score named AECOPD-F. The area under the curve of the score for the prediction of prolonged hospital stay is 0.960, and a cutoff point ≥ 3 predicts prolonged stay with a sensitivity of 84.5% and a specificity of 92.5% (95% CI 0.917-0.984). The AECOPD-F score was validated in a second group of 88 subjects admitted to the hospital for a COPD exacerbation. In the validation group, subjects with a score ≥ 3 required prolonged stay compared with those with a score < 3 (8.0 [6.0-10.0] vs 6.5 [4.0-9.0] d, respectively, P = .007). CONCLUSION: The AECOPD-F score could accurately predict stay in hospitalized COPD subjects. The implementation of this score in clinical practice could be useful in the discharge planning of such subjects.

Collateral damage: depressive symptoms in the partners of COPD patients.

BACKGROUND: Depression is a frequent comorbidity in COPD patients and is associated with greater physical impairment, increased health-care utilization, and worse outcomes. The presence of depressive symptoms in the partners of COPD patients has not been evaluated. METHODS: We evaluated the partners of 230 consecutive COPD patients included in a prospective study. Depressive symptoms were evaluated using Beck's Depression Inventory (BDI) on the first day of admission for COPD exacerbation. Patients were followed-up for 1 year. RESULTS: Significant depressive symptoms were present in 39.6 % of the COPD patients and in 40.9 % of their partners. Beck scores were higher in the partners of patients with severe airflow obstruction and in those with ≥2 exacerbations and ≥1 hospitalizations for COPD exacerbation during the 1-year follow-up. The BDI score of the patients' partners was significantly correlated with the BDI score of the COPD patients (r s = 0.422). In multivariate analysis, depressive symptoms in the COPD patients were an independent predictor of depressive symptoms in their partners (OR 4.136, 95 % CI 1.991-8.594; p < 0.001). CONCLUSIONS: A large proportion of the partners of COPD patients present significant depressive symptoms. The identification of those patients and their partners represents a possible target for intervention.

The impact of depressive symptoms on recovery and outcome of hospitalised COPD exacerbations.

The impact of depressive symptoms on outcomes of acute exacerbations of chronic obstructive pulmonary disease (AECOPD) has not been thoroughly evaluated in prospective studies. We prospectively enrolled 230 consecutive patients hospitalised for AECOPD, without previous diagnosis of depression. Depressive symptoms were evaluated with Beck's depression inventory. Pulmonary function tests, arterial blood gases, COPD assessment test (CAT) and Borg dyspnoea scale were recorded on admission and on days 3, 10 and 40. Patients were evaluated monthly for 1 year. Patients with depressive symptoms required longer hospitalisation (mean ± sd 11.6 ± 3.7 versus 5.6 ± 4.1 days, p<0.001). Clinical variables improved during the course of AECOPD, but depressive symptoms on admission had a significant impact on dyspnoea (p<0.001) and CAT score (p = 0.012) improvement. Patients with depressive symptoms presented more AECOPD (p<0.001) and more hospitalisations for AECOPD (p<0.001) in 1 year. In multivariate analysis, depressive symptoms were an independent predictor of mortality (hazard ratio 3.568, 95% CI 1.302-9.780) and risk for AECOPD (incidence rate ratio (IRR) 2.221, 95% CI 1.573-3.135) and AECOPD hospitalisations (IRR 3.589, 95% CI 2.319-5.556) in 1 year. The presence of depressive symptoms in patients admitted for AECOPD has a significant impact on recovery and is related to worse survival and increased risk for subsequent COPD exacerbations and hospitalisations in 1 year.

Comparison of two gamma interferon release assays and tuberculin skin testing for tuberculosis screening in a cohort of patients with rheumatic diseases starting anti-tumor necrosis factor therapy.

Gamma interferon release assays (IGRAs) are increasingly used for latent Mycobacterium tuberculosis infection (LTBI) screening in patients with rheumatic diseases starting anti-tumor necrosis factor (anti-TNF) therapies. We compared the performances of two IGRAs, an enzyme-linked immunospot release assay (T-SPOT.TB) and an enzyme-linked immunosorbent assay (QuantiFERON-TB Gold In Tube [QFT-GIT]), to that of tuberculin skin testing (TST) for LTBI screening of 157 consecutive rheumatic patients starting anti-TNF therapies. Among 155 patients with valid results, 58 (37%) were positive by TST, 39 (25%) by T-SPOT.TB assay, and 32 (21%) by QFT-GIT assay. IGRAs were associated more strongly with at least one risk factor for tuberculosis (TB) than TST. Risk factors for a positive assay included chest X-ray findings of old TB (TST), advanced age (both IGRAs), origin from a country with a high TB prevalence, and a positive TST (T-SPOT.TB assay). Steroid use was negatively associated with a positive QFT-GIT assay. The agreement rate between IGRAs was 81% (kappa rate = 0.47), which was much higher than that observed between an IGRA and TST. If positivity by either TST or an IGRA was required for LTBI diagnosis, then the rate of LTBI would have been 46 to 47%, while if an IGRA was performed only for TST-positive patients, the respective rate would have been 11 to 17%. In conclusion, IGRAs appear to correlate better with TB risk than TST and should be included in TB screening of patients starting anti-TNF therapies. In view of the high risk of TB in these patients, a combination of one IGRA and TST is probably more appropriate for LTBI diagnosis.
