Öğe Antibiotic resistance rates and penicillin MIC distribution in patients with streptococcal pneumonia between 2013-2019, and use of antibiotics in clinical practice(Elsevier, 2022) Anar, Ceyda; Bicmen, Can; Guldaval, Filiz; Atay, Tuba; Gayaf, Mine; Balci, Gunseli; Alici, Ibrahim Onur; Doğan, Betül İkbal; Büyükşirin, Melih; Ayrancı, Aysu; Karadeniz, Gülistan; Polat, GülruPurpose: The purpose of the present study is to investigate the antibiotic resistance rates and use of antibiotics in patients with streptococcal pneumonia in a reference tertiary care hospital for pulmonary diseases in Izmir, Turkey.Methods: A total of 1224 cases with streptococcal pneumonia between 2013 and 2019 were included in the study, retrospectively. Drug susceptibility testing for penicillin and other antibiotics were performed according to the recommendations of EUCAST criteria. Clinical data and general characteristics were collected and evaluated for each patient in accordance with the susceptibility testing report.Results: Totally, resistance rates for trimethophrim-sulfamethoxazole, penicillin (oxacillin), erythromycin, tetra-cycline, clindamycin and levofloxacin resistance were 63.5%, 39.8%, 37.7%, 37.6%, 28.8%, and 4.8%, respec-tively. Antibiotic resistance was not detected against vancomycin,teicoplanin and linezolid. Multidrug resistance rate was found to be 27.1%. It was observed that there was a statistically significant decrease in trimethophrim-sulfamethoxazole, penicillin (oxacillin), erythromycin, clindamycin and levofloxacin resistance rates by years (p: 0.000, 0.004, 0.000, 0.001, 0.010, respectively). The penicillin MIC distribution was higher at the range of 0.12-2 mu g/mL and there was statistical difference among the ranges of MIC values for the representative years (p:0.033). Among the antibiotics investigated, the most commonly used antibiotic was moxifloxacin.Conclusions: Trimethophrim-sulfamethoxazole resistance rate has been found higher than other antibiotics. As penicillin MIC values were at the range of 0.12-2 mu g/mL frequently, high doses of penicillin treatment might be required in some patients. It is noteworthy that significant decrease in resistance rates in penicillin, erythromycin, clindamycin and tetracycline could be due to the vaccination programme carried out since 2008 in Turkey. As the empiric use of quinolones is high it would be more appropriate to use it according to the susceptibility testing. It is important to determine the regional antimicrobial susceptibility for Streptococcus pneumoniae to select appropriate empirical antimicrobials in the clinical practice.Öğe Clinical effects of T790M mutation in EGFR tyrosine kinase inhibitor resistant NSCLC patients(2021) Anar, Ceyda; Kömürcüoğlu, Berna; Polat, Gülru; Büyükşirin, Melih; Batum, Özgür; Erdoğan, Kadri Murat; Güldaval, FilizINTRODUCTION: To compare patient characteristics between the T790M-positive and T790M-negative populations, and to analyze the post-progression survival (PPS) after initial tyrosine kinase inhibitor (TKI) failure in order to investigate the prognosis in patients undergoing rebiopsy. METHODS: We investigated the patient characteristics, including the initial EGFR-TKI response and T790M status at the time of rebiopsy or liquid biopsy, subsequent treatment after resistance to the initial EGFR-TKI (the presence of EGFR-TKI re-challenge), treatment just before biopsy and/or rebiopsy (EGFR-TKIs or chemotherapy), the timing of the rebiopsy (just after the initial EGFR-TKI failure or others). RESULTS: No difference was found between the two groups with T790M mutation positive and negative in terms of age, gender, and metastasis location. Only patients with positive T790M mutation had higher progression after TKI use compared to negative ones (p: 0.000). The progression-free median survival in patients using TKI was 19.33 months in the group with T790M mutation and 22.25 months in the negative group. Overall survival was found to be 75 months and 27.5 months in the T790M positive and negative group, respectively, and this was statistically significant. (p: 0.009). DISCUSSION AND CONCLUSION: Overall survival was significantly longer in the T790M positive group than in the T790M negative group. In addition, liquid biopsy can be performed several times for patients with progression after EGFR-TKI use and who do not want to undergo tissue biopsyÖğe COVID-19 sonrası devam eden semptomlar, interstisyel akciğer hastalığı oluşumu ve takip süreci(2021) Yavuz, Melike Yüksel; Anar, CeydaAralık 2019’da Çin’in Wuhan eyaletinden severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2)’ye bağlı ciddi akut solunum hastalıkları bildirildi. Koronavirüs hastalığı- 2019 (COVID-19) ilişkili semptomlar hafif üst solunum yolu infeksiyonundan akut solunum sıkıntısı sendromu (ARDS)’na kadar çeşitli klinik farklılık gösterir. Taburculuk sonrası bazı hastalarda semptomların ve radyolojik bulguların devam ettiği görülmüştür. Hipertansiyon ve diyabet gibi komorbiditeler, erkek cinsiyet ve ileri yaş gibi risk faktörleri ciddi COVID-19 ve idiopatik pulmoner fibrosis (İPF) için ortak risk faktörleridir. Bununla birlikte, SARS-CoV-2 infeksiyonuna yakalanan İPF hastalarında, antifibrotik tedavinin rolü ve bunların devamı veya kesilmesi için bilimsel mantık tam olarak tanımlanmamıştır. COVID-19 pandemisinden edinilen veriler ile şiddetli akut solunum sendromu (SARS) ve Ortadoğu solunum sendromu (MERS) gibi önceki koronavirüs infeksiyonlarından elde edilen veriler, SARS-CoV-2 infeksiyonunu takiben önemli fibrotik değişiklikler olabileceğini düşündürmektedir. Bu makalede, COVID-19 pnömonisi sonrası devam eden semptomların sıklığı ve ortaya çıkabilecek interstisyel akciğer hastalığı sıklığından söz edildi. Ayrıca başta pulmoner fibrosis olmak üzere akciğerde meydana gelen interstisyel değişikliklerin önlenmesi ve solunum fonksiyonlarında azalma literatür ışığında tartışılmıştır.Öğe Diagnostic value of pleural fluid lactate dehydrogenase/adenosine deaminase ratio in differentiating parapneumonic effusion from tuberculous pleurisy(Wolters Kluwer Medknow Publications, 2021) Anar, Ceyda; Yavuz, Melike Yuksel; Alici, Ibrahim Onur; Guldaval, Filiz; Buyuksirin, MelihObjective The purpose of this study was to determine the diagnostic value of pleural fluid lactate dehydrogenase (LDH)/pleural fluid adenosine deaminase (ADA) ratio in differentiating pleural effusions owing to tuberculous pleurisy (TBP) and parapneumonic effusion (PPE). Patients and methods The data of 272 patients (140 patients with TBP and 132 patients with PPE) between January 2012 and October 2018 were analyzed retrospectively. Demographic data of all patients; concurrent serum glucose, albumin, protein, and LDH values; and pleural fluid pH, glucose, albumin, protein, and ADA results have been reviewed. Results Pleural fluid ADA values were statistically significantly higher in the TBP group than PPE (P<0.001). The median values of pleural fluid LDH/ADA ratio between TBP and PPE groups were 16.10 (12.53) and 32.90 (34.45), respectively, which was found to be significantly lower in TBP group (P<0.001). Pleural fluid LDH/ADA ratio's sensitivity, specificity, positive predictive value, and negative predictive value were 90, 59.85, 70.4, and 84.9%, respectively, in the diagnosis of TBP for values less than 28 (P<0.001). Conclusion The ratio of pleural fluid LDH/ADA determined from routine biochemical analysis predicts TBP at value of 28. Measurement of this parameter may help clinicians distinguish between TBP and PPE.Öğe Effect of host risk factors in identifying mortality in COVID-19 pneumonia and a new COVID-19 mortality index: Co-AMSCA(Kare Publ, 2022) Gayaf, Mine; Anar, Ceyda; Polat, Gülru; Ayrancı, Aysu; Güldaval, Filiz; Karadeniz, Gülistan; Batum, ÖzgürBACKGROUND AND AIM: The purpose of the study was to examine the host risk factors related to mortality in patients hospitalized with coronavirus disease 2019 (COVID-19) pneumonia and to find a COVID-19 mortality score based on these factors. METHODS: Subjects hospitalized with COVID-19 pneumonia between March 11, 2020, and October 1, 2020, were retrospectively analyzed. The age, gender, smoking status, body mass index, blood group, severity of pneumonia, comorbidity, reverse transcriptase-polymerase chain reaction positivity, use of angiotensin-converting enzyme (ACE) inhibitors, radiological changes, and mortality rates of the patients who had proven COVID-19 pneumonia were recorded. Patients were divided into two groups according to mortality status, and the two groups were compared. The cutoff values, sensitivity and specificity values, and odds ratios were calculated to predict mortality of the new scoring system. RESULTS: A total of 422 patients (51 mortal and 371 nonmortal) participated in the study. The univariate regression analysis showed that age, male gender, smoking, comorbidity, and using ACE inhibitors were prognostic host risk factors for COVID-19-related mortality. A new scoring model with the combination of risk factors named Co-AMSCA was created in the study. The cutoff value of the system was found to be 3.5 with 88.4% sensitivity and 65.5% specificity. The mortality risk in patients with a Co-AMSCA mortality score above 3.5 points was 7.8 times higher than that in patients whose score was lower than 3.5 points. In multivariate logistic regression analysis, older age and smoking were significant risk factors for mortality. CONCLUSIONS: A mortality score was created based on host risk factors, which are easy to calculate and do not need laboratory tests and do not waste the time of the clinicians. This study showed that by using Co-AMSCA scoring model, it is possible to achieve a mortality prediction in COVID-19 patients who are hospitalized due to pneumonia.Öğe Evaluation of whether smoking cessation among advanced lung cancer patients has a significant effect on anxiety and depressive symptoms(Kare Publ, 2023) Guldaval, Filiz; Polat, Gulru; Anar, Ceyda; Ayranci, Aysu; Karadeniz, Gulistan; Gayaf, Mine; Turk, Merve AyikBACKGROUND AND AIM: Continued smoking has a detrimental effect on lung cancer patients, which may already be associated with anxiety and depression. There is a belief among some that smoking cessation will further increase anxiety and depression in these patients, reducing their quality of life. In this study, we aimed to determine whether there was a difference in anxiety, depression, and quality of life scores between ex-smokers after the diagnosis of lung cancer and current smokers.METHODS: One hundred patients with advanced lung cancer were included in the study. Demographic characteristics were recorded, and the smoking status of patients was questioned. The Hospital Anxiety and Depression Scale and European Organization for Research and Treatment of Cancer Quality of Life tests were performed to evaluate anxiety, depression, and quality of life.RESULTS: The mean age was 61 & PLUSMN;8 years. Adenocarcinoma was the most common type of cancer, and 64% of the cases were at stage 4. Of the total 100 patients, 8 had never smoked, 23 were smokers, and 69 were ex-smokers. After the diagnosis of lung cancer, 17 patients quit smoking. No statistically significant difference was found between smoking status and anxiety or depression and quality of life scores (p>0.05). There was no difference between anxiety or depression and quality of life scores between patients who quit smoking after the diagnosis and those who continued (p>0.05).CONCLUSIONS: Patients with lung cancer should not be abstained from smoking cessation because of the possibility of increased anxiety or depression; rather, patients should be supported for smoking cessation at any stage.Öğe Göğüs hastalıkları onkolojik acillerin değerlendirilmesi(2020) Tatar, Dursun; Anar, Ceyda; Özdoğan, Yasemin; Yalnız, Enver; Çırak, Ali Kadri; Erbaycu, Ahmet EminAmaç: Göğüs hastalıkları hastanesi acil servisine başvuran onkoloji hastalarının genel özelliklerini ortaya koymak amaçlandı.

We investigated the clinical impact of NLR as a prognostic factor in malign pleural effusion (MPE) and sNLR on prognosis in MPE. Method: We retrospectively reviewed all of the patients who were diagnosed MPE. The relationship between sNLR and neutrophil-to-lymphocyte ratio in the malign pleural effusion (mNLR) value, age, Eastern Cooperative Oncology Group (ECOG), histopathologic type, serum albumin and lactate dehydrogenase (LDH) with survival were investigated. Results: A total of 222 patients with a mean age of 65.7±11.5 were included in the study. Patients with a mNLR value ?0.42 and a serum NLR value ?4.75 had a shorter survival (p: 0.000). Multivariate analysis, which showed that survival was significantly related mNLR value > 0.42 and/or sNLR value > 4.75 (Odds Ratio (OR): 2.66, %95 CI, 1,65-4,3 p: 0.001), serum LDH > 210 (OR = 1.8, %95 CI, 1,33-2,46 p: 0.001) and age > 65 (OR = 1.9, %95 CI, 1,41-2,55 p = 0.001). Conclusion: sNLR and mNLR may act as a simple, useful, and cost-effective prognostic factor in patients with MPE. Furthermore, these results may serve as the cornerstone of further research into the mNLR in the future. Although further studies are required to generalize our results, this information will benefit clinicians and patients in determining the most appropriate therapy for patients with MPE.Öğe What are the differences between smoker and non-smoker COPD cases? is it a different phenotype?(2021) Güldaval, Filiz; Polat, Gülru; Doruk, Sibel; Karadeniz, Gülistan; Ayrancı, Aysu; Türk, Merve; Anar, CeydaOBJECTIVE: The most important risk factor for chronic obstructive pulmonary disease (COPD) is smoking. However, more than 25% of patients do not have a history of smoking. The intent of this study is to identify characteristics of COPD patients that are non-smokers.MATERIAL AND METHODS: The records of patients with COPD were retrospectively reviewed. Smoking history, comorbidities, exacerbations, biomass, and environmental tobacco smoke (ETS) exposures were identified. Also, age, gender, pulmonary function test (PFT) values, modified Medical Research Council (mMRC) dyspnea scores were recorded. Non-smokers exposed to any of the COPD risk factors above were grouped and the data were analyzed to determine the specific characteristics of COPD that applied to them.RESULTS: A total of 706 COPD patients were analyzed with a mean age of 67.2 ± 9.4. Of these patients, 93 (13.2%) were female and 613 (86.8%) were male. Of the 706 patients, 128 (18.1%) were non-smokers. The percentage of male patients having COPD was significantly lower in the non-smoker group (P < .001). However, biomass, ETS exposure in childhood, and a history of previous respiratory infection were significantly higher in the non-smoker group (P < .001). The mean body mass index (BMI) was greater in non-smokers than smokers.CONCLUSION: Non-smokers with COPD have more biomass, ETS exposure, and infection history in childhood. They also have less impairment of airflow limitation, better symptom scores, and greater BMIs. Smoking history can be used to determine a different phenotype.
