RESUMO
OBJECTIVE: Prognostic models aid clinical practice with decision-making on treatment and hospitalization in exacerbation of chronic obstructive lung disease (ECOPD). Although there are many studies with prognostic models, diagnostic accuracy is variable within and between models. SUBJECTS AND METHODS: We compared the prognostic performance of the BAP65 score, DECAF score, PEARL score, and modified early warning score (MEWS) in hospitalized patients with ECOPD, to estimate ventilatory support need. RESULTS: This cross-sectional study consisted of 139 patients. Patients in need of noninvasive or invasive mechanical ventilation support are grouped as ventilatory support groups (n = 54). Comparison between receiver operating characteristic curves revealed that the DECAF score is significantly superior to the PEARL score (p = 0.04) in discriminating patients in need of ventilatory support. DECAF score with a cutoff value of 1 presented the highest sensitivity and BAP65 score with a cutoff value of 2 presented the highest specificity in predicting ventilatory support need. Multivariable analysis revealed that gender played a significant role in COPD exacerbation outcome, and arterial pCO2 and RDW measurements were also predictors of ventilatory support need. Within severity indexes, only the DECAF score was independently associated with the outcome. One-point increase in DECAF score created a 1.43 times higher risk of ventilatory support need. All severity indexes showed a correlation with age, comorbidity index, and dyspnea. BAP65 and DECAF scores also showed a correlation with length of stay. CONCLUSION: Objective and practical classifications are needed by clinicians to assess prognosis and initiate treatment accordingly. DECAF score is a strong candidate among severity indexes.
RESUMO
Introduction: In a resource-constrained situation, a clinical risk stratification system can assist in identifying individuals who are at higher risk and should be tested for COVID-19. This study aims to find a predictive scoring model to estimate the COVID-19 diagnosis." Materials: Patients who applied to the emergency pandemic clinic between April 2020 and March 2021 were enrolled in this retrospective study. At admission, demographic characteristics, symptoms, comorbid diseases, chest computed tomography (CT), and laboratory findings were all recorded. Development and validation datasets were created. The scoring system was performed using the coefficients of the odds ratios obtained from the multivariable logistic regression analysis." Result: Among 1187 patients admitted to the hospital, the median age was 58 years old (22-96), and 52.7% were male. In a multivariable analysis, typical radiological findings (OR= 8.47, CI= 5.48-13.10, p< 0.001) and dyspnea (OR= 2.85, CI= 1.71-4.74, p< 0.001) were found to be the two important risk actors for COVID-19 diagnosis, followed by myalgia (OR= 1.80, CI= 1.08- 2.99, p= 0.023), cough (OR= 1.65, CI= 1.16-2.26, p= 0.006) and fatigue symptoms (OR= 1.57, CI= 1.06-2.30, p= 0.023). In our scoring system, dyspnea was scored as 2 points, cough as 1 point, fatigue as 1 point, myalgia as 1 point, and typical radiological findings were scored as 5 points. This scoring system had a sensitivity of 71% and a specificity of 76.3% for a cut-off value of >2, with a total score of 10 (p< 0.001). Conclusions: The predictive scoring system could accurately predict the diagnosis of COVID-19 infection, which gave clinicians a theoretical basis for devising immediate treatment options. An evaluation of the predictive efficacy of the scoring system necessitates a multi-center investigation.

BACKGROUND: Laboratory biomarkers to estimate the severity of coronavirus disease 2019 (COVID-19) are crucial during the pandemic since resource allocation must be carefully planned. AIMS: To evaluate the effects of basal serum total immunoglobulin E (IgE) levels and changes in inflammatory parameters on the clinical progression of patients hospitalised with COVID-19. METHODS: Patients hospitalised with confirmed COVID-19 were included in the study. Laboratory data and total IgE levels were measured on admission. Lymphocyte, eosinophil, ferritin, d-dimer and C-reactive protein parameters were recorded at baseline and on the 3rd and 14th days of hospitalisation. RESULTS: The study enrolled 202 patients, of which 102 (50.5%) were males. The average age was 50.17 ± 19.68 years. Of the COVID-19 patients, 41 (20.3%) showed clinical progression. Serum total IgE concentrations were markedly higher (172.90 (0-2124) vs 38.70 (0-912); P < 0.001) and serum eosinophil levels were significantly lower (0.015 (0-1.200) vs 0.040 (0-1.360); P = 0.002) in clinically worsened COVID-19 patients when compared with stable patients. The optimal cut-off for predicting clinical worsening was 105.2 ng/L, with 61% sensitivity, 82% specificity, 46.3% positive predictive value and 89.2% negative predictive value (area under the curve = 0.729). Multivariable analysis to define risk factors for disease progression identified higher total IgE and C-reactive protein levels as independent predictors. CONCLUSIONS: Our single-centre pilot study determined that total IgE levels may be a negative prognostic factor for clinical progression in patients hospitalised due to COVID-19 infection. Future studies are required to determine the impact of individuals' underlying immune predispositions on outcomes of COVID-19 infections.

Introduction: Noninvasive ventilation (NIV) for acute hypercapnic respiratory failure (AHRF) is an established treatment modality. Current evidence does not conclude any superiority between fixed pressure support (PS) and average volume-assured pressure support (AVAPS) modes. However, given the ability of rapid PaCO2 decline in AVAPS mode, we hypothesized that COPD patients with AHRF who did not show the desired reduction in PaCO2 with fixed-level PS-NIV might benefit from the AVAPS mode. Materials and Methods: Patients admitted to the non-ICU pulmonary ward with acute exacerbation of COPD (AECOPD) and AHRF were included consecutively in this observational study. Patients with hypercapnic respiratory failure due to obesity-hypoventilation, neurological diseases, or chest wall deformities were excluded. All patients started NIV treatment with fixed pressure support (PS) and patients who did not reach clinical and laboratory stability under PS-NIV treatment were switched to the average volume-assured pressure support (AVAPS) mode of NIV. Result: Thirty-five COPD patients with hypercapnic respiratory failure were included. Under PS-NIV treatment, 14 (40%) patients showed a 17.9 (-0.0-29.2) percent change in terms of PaCO2, meaning no improvement or worsening. Therefore, these patients were treated with AVAPS mode. Arterial PaCO2 and pH levels significantly improved after AVAPS-NIV administration. AVAPS-NIV treatment created a significantly better PaCO2 change rate than using PS-NIV [-11.4 (-22.0 - -0.5) vs 8.2 (-5.3-19.5), p= 0.02]. Independent predictors of AVAPS mode requirement were higher Charlson Comorbidity Index [OR= 1.74 (95% CI= 1.02-2.97)] and higher PaCO2 upon admission [OR= 1.18 (95% CI= 1.03-1.35)]. Thirteen (92.8%) patients reaching significant clinical stability with AVAPS-NIV were able to return to fixed-level PS-NIV and maintain acceptable PaCO2 levels. Conclusions: Our study demonstrated that patients can benefit from AVAPSNIV despite insufficient response to fixed-level PS-NIV.

INTRODUCTION: Tobacco-free college campuses refer to colleges and universities that have implemented policies prohibiting the use of tobacco products at all indoor and outdoor campus locations. We aimed to evaluate university students' smoking behaviors and their attitudes towards "Tobacco-Free Campus Policy". MATERIALS AND METHODS: A total of 10,383 university students were included in this cross-sectional study. The questionnaire was sent via web-based student information system. Demographical variables, the frequency of tobacco use, the addiction levels of the smoker students, and their perspective on the Tobacco-Free Campus Policy were evaluated. RESULT: The study population consisted of 5461 (52.6%) males and their mean age was 22.1 ± 3.9 years. Among the students, 3992 (38.4%) were current smokers and the age of first smoking was 16.5 ± 2.78 years. According to FTND scores, 15.1% of participants have high dependence, and 7.5% of them have very high dependence. There was a significant difference among participants who finds unacceptable "Tobacco-Free Campus Policy" in terms of gender (70.7% males vs. 29.3% females, p<0.001) and smoking habit (7% never smoker, 4.1% ex-smoker, 88.9% current smoker, p<0.001). CONCLUSIONS: The Tobacco-Free Campus Policy is important to fight against the tobacco industry in order to protect the right to health of all tobacco users and those who do not use it and should be considered as a goal to be achieved in order to live in a healthy environment.

INTRODUCTION: Chronic Obstructive Pulmonary Disease (COPD) exacerbations contribute to the overall severity in individual patients because they are associated with airway inflammation, pulmonary function loss, decreased quality of life and increased mortality. Although, identifying frequent exacerbator patients is important due to severe outcomes associated with frequent exacerbator phenotype in COPD patients there is no single biomarker which can differentiate this phenotype. Iron responding protein-2 (IRP2) is the protein product of IREB2 gene, which is a COPD susceptibility gene that regulates cellular iron homeostasis and has a key role in hypoxic conditions. Previous research indicates that IREB2 expression in lung tissue is associated with spirometric measurements and emphysema in COPD. In this study, our aim was to investigate whether serum IRP2 levels were associated with frequent exacerbator phenotype, to evaluate whether IRP2 levels in serum are associated with pulmonary functions and selected systemic inflammation biomarkers. MATERIALS AND METHODS: Designed as a single tertiary care center based, crosssectional study, included high risk (GOLD C, D) COPD patients who admitted to outpatient clinic consecutively between December 2015 and July 2016. RESULT: The study included 80 COPD patients. Serum IRP2 levels were negatively correlated with FEV1 ml (r= -0.25, p= 0.02) and body weight (r= -0.35, p= 0.002) but not with markers of systemic inflammation. COPD patients with at least one exacerbation history in the last year tended to have higher IRP2 levels than patients without any exacerbation [12.3 (IQR 25-75: 10.4- 17.1) vs 10.5 (IQR 25-75: 8.8-18.5), p= 0.06]. CONCLUSIONS: Serum IRP2 level is significantly correlated with FEV1 mL but not with FEV1 % predicted and cannot be used to differentiate frequent exacer bator patients. Although IREB2 gene expressions in lung tissue and bronchoalveolar lavage results have significant associations with emphysema and FEV1/FVC, FEV1 %predicted in COPD patients, our results suggests serum IRP2 level is not as promising.

OBJECTIVE: This study aimed to evaluate the factors that affect asthma control and adherence to treatment in newly diagnosed elderly asthmatics in Turkey compared with younger patients. METHODS: This real-life prospective observational cohort study was conducted at 136 centers. A web-based questionnaire was administered to the patients who were followed up for 12 months. RESULTS: Analysis included 1037 young adult asthma patients (age <65 years) and 79 elderly asthma patients (age ≥65 years). The percentage of patients with total control in the elderly and young groups were 33.9% and 37.1% at visit 1, 20.0% and 42.1% (p = 0.012) at visit 2, and 50.0% and 49.8% at visit 3, respectively. Adherence to treatment was similar for both groups. Visit compliance was better in the elderly group than in the young group at visit 1 (72.2% vs. 60.8%, p = 0.045), visit 2 (51.9% vs. 34.9%, p = 0.002), and visit 3 (32.9% vs. 19.4%, p = 0.004). Adherence to treatment increased with asthma control in both groups (both p < 0.001) but decreased with the presence of gastritis/ulcer, gastroesophageal reflux, and coronary artery disease in the elderly. CONCLUSIONS: Asthma control and adherence to treatment were similar for the elderly and young asthma patients, though the follow-up rate was lower in young patients. The presence of gastritis/ulcer, gastroesophageal reflux and coronary artery disease had negative impacts on the adherence to treatment in elderly adult patients.

INTRODUCTION: Despite the presentation of similar symptoms, the airway diseases have different underlying pathophysiological processes and must be distinguished to enable the administration of appropriate treatment. In several studies the clinician- and patient-related causes of poor compliance to treatment in asthma/chronic obstructive pulmonary disease (COPD) patients have been evaluated. This study aimed to determine the clinical and sociodemographic characteristics of newly diagnosed treatment-naïve asthma and COPD patients in Turkey. MATERIALS AND METHODS: This national, multicentre, prospective, observational study was conducted in 122 centres. A questionnaire including items related to demographic, clinical, laboratory parameters was applied. All patients were intended to be followed-up for 12 months. RESULT: 1892 adult patients (1116 asthma and 776 COPD) from 122 centres were enrolled. Overall 95%, 86% and 65% of intermittent, mild persistent and moderate persistent asthma patients were over-treated. Among COPD patients, the percentages of over-treated patients were 66%, 79% and 82% for those with GOLD stage A, B and C. Physicians' adherence to guidelines was appropriate in 93% of severe persistent asthma patients and 89% of GOLD stage D COPD patients. Among patients with high compliance to treatment, proportion of asthma patients with total control was 44% and that of COPD patients at GOLD stage A was 41%. In consecutive two visits, this figure increased to 52% and 63% in asthma patients and 54% and 50% in COPD patients. CONCLUSIONS: The main findings are: (a) patients are frequently over-treated and (b) patients do not adhere to visits as expected, in both asthma and COPD.

Chronic obstructive pulmonary disease (COPD) is a complex disease that is associated with devastating outcomes resulting from lung involvement and several comorbidities. Comorbidities could impact on symptomology, quality of life, the complications, the management, economic burden and the mortality of the disease. The importance of comorbidities originates from their impact on the outcome of COPD. The most frequent comorbidities in COPD are cardiovascular, endocrinological, musculoskeletal, phycological disorders and lung cancer. Almost 50% of the COPD patients have 3 or more comorbidities. The recent Global Initiative of Obstructive Lung Disease (GOLD) Guideline suggested proactive search and the treatment of the comorbidities. However, there is no certain evidence demonstrating that active treatment of comorbidities improve the outcomes of COPD. However, it is well known that several comorbidities such as cardiovascular disease and lung cancer have greater impact on mortality caused by COPD. Several studies have shown that Charlson Comorbidity index or more recenty COPD Specific Comorbidity Index (COTE) has been found to be related with mortality of COPD. This concise review intended to summarize the most frequent comorbidities in association with their impact on COPD.

INTRODUCTION: Pneumocystis pneumonia (PCP) which is caused by Pneumocystis jirovecii is usually seen in the patients whose immune system is supressed. It is seriously seen an opportunist infection. In our study; totally 100 bronchoalveolar lavage (BAL) and bronchial washing samples collected by pulmonary disease department. Which belong to the patients in the clinics, and out patient clinic of the bronchoscopy material were evaluated. MATERIALS AND METHODS: The BAL and bronchial washing were evaluated by the help of methenamine silver stain (Gomori/Grocott), toluidine blue O stain, Wright-Giemsa stain, immun fluorescent antibody (IFA) stain, nested polymerase chain reaction (PCR). RESULTS: In the BAL and bronchial washing samples the agent couldn't be shown by the help of methenamine silver (Gomori/Grocott), toluidine blue O, Wright-Giemsa staining. In 13 patients with IFA test the cysts of P. jirovecii were determined. In 16 patients with nested PCR; the DNA of P. jirovecii were determined. In 8 patients by using PCR and IFA test P. jirovecii was determined. When the samples which had P. jirovecii were analyzed; 13 of them were BAL and 8 of them were bronchial washing. When the phenomenon groups were evaluated according to age, gender, smoking, hypertension, diabetes mellitus, chronic obstructive pulmonary disease (COPD), cerebrovascular accident (CVA), congestive cardiac failure (CCF), staying in the hospital in the last three months, using antibiotics and radiological findings; there wasn't a statistical meaningful relation between P. jirovecii positivity and these situations. When the phenomenon groups were evaluated according to PCR and IFA positivity; in IFA and PCR positive patients for immunosupressive there was a meaningful differances (p= 0.003). The positive 28.6 % of cases were immunosuppressed and the 3.8% of PCR or IFA negative cases were immunosupressed. When PCR method was compared with IFA which is called gold standard for sensitivity and specificity; sensitivity was found 61.5% and specificity was found 90.8%. IFA and PCR diagnosis test results were compatible (With McNemar test p= 0.581). CONCLUSION: Diagnostic sensitivity of staining methods for P. jirovecii in immunocompromised HIV negative patients are found to be low and it was shown that IFA and nested PCR methods have not parallel results.

The population of the Region (Central Europe, Eastern Europe, and Israel) is ageing, necessitating preventative programmes to maintain a healthy and active lifestyle in older age groups. Invasive pneumococcal disease (including bacteremic pneumonia, bacteremia without a focus, and meningitis) has higher incidence, morbidity and mortality in older adults and is a substantial public health burden in the ageing population. Surveillance in the Region establishes a significant burden in older adults of invasive pneumococcal disease (IPD), which still appears to be under-estimated as compared with other countries, and this warrants an improvement in surveillance systems. The largest proportion of IPD in adults is bacteremic pneumonia. Community-acquired pneumonia (CAP), largely attributable to S. pneumoniae, can be bacteremic or non-bacteremic; the non-bacteremic forms of CAP also represent a significant burden in the Region. The burden of pneumococcal disease can be reduced with programmes of effective vaccination. Recommendations on pneumococcal vaccination in adults vary widely across the Region. The main barrier to implementation of vaccination programmes is low awareness among healthcare professionals on serious heatlh consequences of adult pneumococcal disease and of vaccination options. The Expert Panel calls on healthcare providers in the Region to improve pneumococcal surveillance, optimize and disseminate recommendations for adult vaccination, and support awareness and education programmes about adult pneumococcal disease.

INTRODUCTION: Etiology of sarcoidosis is unknown but the prevalence of disease in different ethnic groups and identical twins, family characteristics indicate that genetic predisposition is a possible factor. The angiotensin-converting enzyme (ACE) has been implicated in the pahophysiology of sarcoidosis. The aim of this study is to investigate the influence of a polymorphism in I/D (Insertion/Deletion) of the ACE gene on the susceptibility to sarcoidosis. PATIENTS AND METHODS: Our study included 70 Turkish patients who had histopathological diagnosis of sarcoidosis and 69 healthy age and sex matched control subjects. Polymerase chain reaction was used for analysing an I/D polymorphism in the gene coding for ACE. Genotyping was done according to bands that were formed on the agarose gel electrophoresis. Chi-square test was used for statistical analysis and p< 0.05 was accepted as significance. RESULTS: Although the D allele was more frequent in the sarcoidosis patients group, the frequency of the D allele was 67% and 54% respectively in the sarcoidosis and the control group. No significant difference in allele frequencies of I/I, I/D, D/D polymorphisms was observed between the sarcoidosis and control group (p> 0.05). Similarly allele frequencies of I/I, I/D, D/D polymorphisms was not different between sarcoidosis patients with extrapulmonary involvement and sarcoidosis patients without extrapulmonary involvement (p> 0.05). CONCLUSION: Our findings have showed that contribution of ACE gene polymorphisms to susceptibility of disease development in Turkish sarcoidosis patients is not different from the healthy control subjects.

INTRODUCTION: Eosinophilic airway inflammation is a recognized inflammatory pattern in subgroups of patients with chronic obstructive pulmonary disease (COPD). However, there are still conflicting results between various studies concerning the effect of eosinophils in COPD patients. Our aim with this study was to evaluate eosinophilic inflammation and its relation to the clinical characteristics in a group of COPD patients. METHODS: Stable COPD patients with FEV1 % predicted < 50 or with ≥ 1 exacerbation leading to hospital admission or ≥2 moderate or severe exacerbation history were consecutively enrolled from outpatient clinics. RESULTS: We included 90 male COPD patients, with a mean age of 63.3 ± 9.2. Mean FEV1 % predicted was 35.9 ± 11.3. Eosinophilic inflammation (eosinophil percentage ≥2%) was evident in 54 (60%) of the patients. Participants with eosinophilic inflammation were significantly older and had better FEV1 predicted % values. Eosinophilic COPD patients were characterized with better quality of life and fewer symptoms. COPD patients with noneosinophilic inflammation used supplemental long-term oxygen therapy (LTOT) more frequently compared to patients with eosinophilic inflammation (36.1% vs. 14.8%, p = 0.01). Eosinophilic inflammation is associated with less dyspnea severity measured by mMRC (OR: 0.542 95% CI: 0.342-0.859, p = 0.009) and less LTOT use (OR: 0.334 95% CI: 0.115-0.968, p = 0.04) regardless of age, severity of airflow limitation, and having frequent exacerbation phenotype. CONCLUSION: Our study supports the growing evidence for a potential role of eosinophilic inflammation phenotype in COPD with distinctive clinical characteristics. Eosinophilic inflammation is inversely associated with dyspnea severity measured by mMRC and LTOT use independently from age, total number of exacerbations, St. George Respiratory Questionnaire (SGRQ) total score and FEV1 % predicted.

Background Combined pulmonary fibrosis and emphysema (CPFE) has been recognised as a phenotype of pulmonary fibrosis. We aimed to compare serum surfactant protein-A (SP-A), surfactant protein-D (SP-D) and Krebs von den Lungen-6 (KL-6) levels, functional parameters, in CPFE and IPF (idiopathic pulmonary fibrosis) patients. Methods Patients diagnosed with 'CPFE' and 'IPF' were consecutively included in 6 months as two groups. The patients with connective tissue diseases are excluded. Results In this study, 47 patients (41 males, 6 females) with CPFE (n = 21) and IPF (n = 26) with a mean age of 70.12 ± 8.75 were evaluated. CPFE patients were older, had more intense smoking history, had lower DLCO/VA, lower FVC, and worse six-minute walking distance than the IPF group (p=0.005, p=0.027, p=0.02, p<0.001, p=0.001, respectively). Serum KL-6 levels were higher in CPFE group compared to IPF group [264.70 U/ml (228.90-786) vs 233.60 (101.8-425.4), p<0.001]. Serum KL-6 levels of 245.4 U/ml and higher have 81% sensitivity and 73% specificity for the discrimination of CPFE from IPF. Conclusions Our study has shown that serum KL-6 level is a promising biomarker to differentiate CPFE from IPF. In CPFE cases respiratory and functional parameters are worse than those of pure fibrosis cases.
RESUMO
Tobacco addiction, which causes the death of more than 8.5 million people in the world every year, is a preventable global public health problem. There are 1.1 billion adult smokers worldwide and 60% of them desire or intend to quit but unfortunately, the tobacco industry continues to profit at the expense of people's lives by marketing electronic cigarettes and heated tobacco products as a smoking cessation method and they continue to poison young people with new threat tobacco products, promising a "smoke-free future" Turkish Thoracic Society is actively involved in the implementation of the National Tobacco Control Program to protect public health and has warned and raised awareness of new threats to the youth, such as electronic cigarettes and heated tobacco products. The purpose of this report is to provide information about electronic cigarettes and heated tobacco products and to present TTJ's position on the subject.
RESUMO
BACKGROUND: The potential role of interleukin-6 (IL-6) in coronavirus disease 2019 (COVID-19) pneumonia provides the rationale for investigating IL-6 signaling inhibitors. OBJECTIVES: To evaluate and report treatment responses to tocilizumab (TCZ) in COVID-19 patients and compare mortality outcomes with those of standard care. MATERIAL AND METHODS: Patients hospitalized with a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, diagnosed with reverse transcription polymerase chain reaction (RT-PCR) between March 2020 and April 2021, were enrolled in this single-center retrospective cohort study. Propensity score matching was performed in order to reduce confounding effects secondary to imbalances in receiving TCZ treatment. RESULTS: A total of 364 patients were included in this study. Two hundred thirty-six patients received standard care, while 128 patients were treated with TCZ in addition to standard care (26 (20.3%) patients received a dose of 400 mg intravenously once, while 102 (79.7%) patients received a total dose of 800 mg intravenously). In the propensity score-matched population, less noninvasive mechanical ventilation (p = 0.041) and mechanical ventilation support (p = 0.015), and fewer deaths (p = 0.008) were observed among the TCZ-treated patients. The multivariate adjusted Cox regression model showed a significantly higher survival rate among TCZ patients compared to controls (hazard ratio (HR): 0.157, 95% confidence interval (95% CI): 0.026-0.951; p = 0.044). The hazard ratio for mortality in the TCZ group was 0.098 (95% CI: 0.030-0.318; p = 0.0001 using log-rank test). CONCLUSIONS: This study determined that TCZ treatment in COVID-19 patients was associated with better survival, reduced need for mechanical ventilation and reduced hospital-associated mortality.

INTRODUCTION: Determining prognostic factors in patients with coronavirus disease (COVID-19) can have great impact on treatment planning and follow-up strategies. Herein, we aimed to evaluate prognostic factors and clinical scores for confirmed COVID-19 patients in a tertiary-care hospital in the Bursa region of Turkey. METHODOLOGY: Patients who had been diagnosed with COVID-19 microbiologically and/or radiologically between March and October 2020 in a tertiary-care university hospital were enrolled retrospectively. Adult patients (≥ 18 years) with a clinical spectrum of moderate, severe, or critical illness were included. The dependent variable was 30-day mortality and logistic regression analysis was used to evaluate any variables with a significant p value (< 0.05) in univariate analysis. RESULTS: A total of 257 patients were included in the study. The mortality rate (30-day) was 14.4%. In logistic regression analysis, higher scores on sequential organ failure assessment (SOFA) (p < 0.001, odds ratio (OR) = 1.86, 95% CI = 1.42-2.45) and CURB-65 pneumonia severity criteria (p = 0.001, OR = 2.60, 95% CI = 1.47-4.57) were found to be significant in predicting mortality at admission. In deceased patients, there were also significant differences between the baseline, day-3, day-7, and day-14 results of D-dimer (p = 0.01), ferritin (p = 0.042), leukocyte (p = 0.019), and neutrophil (p = 0.007) counts. CONCLUSIONS: In our study of COVID-19 patients, we found that high SOFA and CURB-65 scores on admission were associated with increased mortality. In addition, D-dimer, ferritin, leukocyte and neutrophil counts significantly increased after admission in patients who died.

OBJECTIVE: This study aimed to evaluate attitude and practice toward use of regular tobacco cigarettes and electronic cigarettes among pregnant women. MATERIAL AND METHODS: A total of 1123 pregnant women participated on a voluntary basis in this questionnaire survey. Maternal characteristics, cigarette consumption parameters, and personal opinions regarding the adverse effects of smoking during pregnancy were evaluated. RESULTS: Active smokers composed 12.4% (9.4%: regular tobacco cigarettes, 3.0%: electronic cigarettes) of the study population. Smoking during the current pregnancy, particularly via regular tobacco cigarettes, was more likely for women with smoking during previous pregnancies (56.0% vs. 7.8%, P < .001), previous history of low birth weight infant delivery (16.1% vs. 8.6%, P = .013), premature delivery (16.7% vs. 7.0%, P < .001), and stillbirth (22.8% vs. 11.7%, P = .002). The presence versus absence of smoking during pregnancy was associated with a lower likelihood of being a housewife (70.5% vs. 80.5%, P = .010) and a higher likelihood of having an actively smoking mother (25.9% vs. 11.2%, P < .001) or partner (65.7% vs. 46.9%, P < .001). Regular tobacco cigarette users considered electronic cigarettes to have a higher risk of adverse impacts (11.1% vs. 2.9%, P = .012), while electronic cigarette users considered regular cigarettes to have a higher risk of nicotine exposure (55.9% vs. 13.0%, P < .001). CONCLUSION: Our findings indicate being employed, having an actively smoking mother or partner, as well as smoking in previous pregnancies, to be the risk factors for increased likelihood of smoking during pregnancy.
RESUMO
INTRODUCTION: Our knowledge has gaps regarding severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) replication levels and its association to severity of Coronavirus disease 2019 (COVID-19). The aim of this study was to investigate the association of SARS-CoV-2 viral load with disease severity and serum biomarkers in COVID-19 patients. METHODOLOGY: Viral load was determined via cycle threshold (Ct) values of SARS-CoV-2 real-time reverse transcriptase-polymerase chain reaction (RT-PCR) in 214 adult patients. Ct values were compared with clinical severity, biochemical and hematological biomarkers. RESULTS: Clinical course of the disease was mild (49.1%), moderate (40.2%), and severe (10.7%). Median Ct value was 28.2 (IQR: 22.2-33.8) during the first week of the disease. Ct values were lower within five days after symptom onset [lowest Ct value on the third day (median: 24, IQR: 20.6-32.3)], but they increased significantly during the second and third weeks. No association was detected between admission Ct values and disease severity. Gender, age, co-morbidity, and mortality did not differ significantly in patients with low (≤ 25) and high (> 25) Ct values. White blood cell, neutrophil, platelet, and especially lymphocyte counts, were significantly lower in patients with low Ct values. CONCLUSIONS: No definitive/clear correlation between SARS-CoV-2 viral load and severity and mortality was found in the studied COVID-19 patients. However, neutrophil, platelet, and especially lymphocyte count were significantly lower in patients with a high viral load.

BACKGROUND AND OBJECTIVE: Extrapulmonary sarcoidosis is common, and is almost always associated with concomitant thoracic involvement. Extrapulmonary manifestations vary on the basis of gender, age at presentation and ethnicity. The aim of this study was to investigate extrapulmonary involvement in patients with sarcoidosis in Turkey. METHODS: This study was conducted by Turkish Thoracic Society Clinical Problems Study Group. New cases of sarcoidosis between 1 June 2004 and 31 May 2006 were recorded on electronic case record forms sent to all potential investigators and information about extrapulmonary involvement was collected. RESULTS: One hundred and nineteen of 293 patients (83 female, 36 male, mean age = 45 ± 12 years) had extrapulmonary involvement in this study (40.6%). The median time to diagnosis was 6 months and this was longer than patients with just thoracic sarcoidosis (P = 0.001). Extrapulmonary symptoms were present in 181 (61.8%) patients, and skin lesions, arthralgia and back pain were the commonest (33.4%, 20.8% and 16.4%, respectively). Incidence of organ involvement was independent of age with the exception of ocular involvement, which was higher in those under the age of 40 years (P = 0.007). CONCLUSIONS: Skin and peripheral lymph node involvement were the most common sites of extrapulmonary involvement and ocular involvement was more common in those under the age of 40 years in patients with sarcoidosis in a Turkish population.
