    (2022-01-01) KOCAKAYA, DERYA; OLGUN YILDIZELİ, ŞEHNAZ; ERYÜKSEL, SEMİHA EMEL; CEYHAN, BERRİN; CEYHAN B., Bekir M., KOCAKAYA D., OLGUN YILDIZELİ Ş., ERYÜKSEL S. E.
    OBJECTIVE: Bronchiectasis is a chronic suppurative lung disease that significantly impacts the patients\" quality of life. The aim of this study is to evaluate the relationship between quality of life and patient\"s psychological status and bronchiectasis disease severity indexes in patients with non-cystic fibrosis bronchiectasis. We also aimed to investigate the validity and reliability of Turkish version of Quality of Life Questionnaire-Bronchiectasis (V3.1) in Turkish adult bronchiectatic patients.

    © 2023 The Author(s)Objectives: The underlying mechanisms for the development of chronic thromboembolic pulmonary hypertension and prognostic biomarkers are not clear yet. Thus, our aim is to assess and identify new biomarkers for the expression of 84 key genes linked to angiogenesis. Methods: Patients who had levels more than 1000 dynes·sec·cm−5 were included in the test group, and the other patients were included in the control group. Twelve specimens were taken from the patients. RT2 Profiler PCR Array (Qiagen) was used to quantify the expression of the 84 key genes. Results: Eight patients (6 male, 2 female, median age 54.4 ± 13.1 years) who underwent pulmonary endarterectomy were included. Pulmonary vascular resistance improved significantly from 811 ± 390 dyn/s/cm−5 to 413.3 ± 144.9 dyn/s/cm−5 (P .005) after surgery. Median length of hospital stay was 11.62 ± 2.97 days. The test group had a distinct pattern of impaired angiogenic and antiangiogenic genes. The expression levels of TGFA, TGFB1, THBS2, THBS1, TGFBR1, SERPINE1, SERPINF1, TGFB2, TIMP2, VEGFC, IFNA1, TNF, CXCL10, NOS3, IGF1, and MMP14 were downregulated in the specimens from the patients who had higher pulmonary vascular resistance values, whereas some genes, including PDGFA, showed upregulation that was statistically nonsignificant in the same group. Conclusions: These results can lead to the development of new markers that could predict adverse outcomes of patients with CTEPH. Identification of new markers that are related to worse outcomes would enable screening patients for early diagnosis and treatment.

    Amaç: Malign melanoma melanositlerin malign transfomayonu sonucu gelişir.Pulmoner metastazını pulmoner arterlere ulaşan tümör embolileri yoluyla yapar.Endobronşial yayılımlı malign melonom vakaları sınırlı sayıdadır. Gereç ve Yöntem: Nadir görülen endobronşial yayılım yapmış bronkoskopi ile tanı koyduğumuz vakamızı sunduk. Bulgular: 42 yaşında bayan hasta nefes darlığı şikaye ile başvurdu. 2006 da tanı konan sır a konjenital dev nevüs tanısı mevcu u.5 paket/yıl sigara hikayesi mevcu u. Fizik muayenede bel bölgesinde 25x15 cm boyularında yaklaşık tüm lumbar bölgeyi kaplayan gluteal bölgeye de yayılan dev nevüsü mevcu u. Vücu a özellikle sır a ve saçlı deride birden fazla çok sayıda nevüsler izlendi. Nevüslerde renk değişikliği tariflemiyordu. Sır aki dev nevüste kalınlaşma belir yordu. Solunum sistemi muayenesi doğaldı.Aksiller ele gelen 1x2 cm lik lenfadenopa si mevcu u. PA akciğer grafisinde sol hilar bölgede düzensizlik ve dansite ar şı mevcu u.

    Increased D-dimer is associated with disease progression and increased mortality in Turkish COVID-19 patients
    (2023-05-31) MERCANCI, ZEYNEP; ILGIN, CAN; OLGUN YILDIZELİ, ŞEHNAZ; KOCAKAYA, DERYA; BALCAN, MEHMET BARAN; KARAKURT, SAİT; ERYÜKSEL, SEMİHA EMEL; Mercanci Z., ILGIN C., Yildizeli S. O., KOCAKAYA D., Balcan B., Sengel B. E., KARAKURT S., Eryuksel E.
    Objective: Coagulopathy is thought to play an important role in the development of severe COVID-19. High D-dimer levels have been reported in Chinese cohort studies. However, ethnicity has significant implications for thrombotic risk. Our aim in this study is to determine the effect of D-dimer measurements on disease prognosis and mortality in Turkish patients with COVID-19. Patients and Methods: The study was designed retrospectively. Patients over the age of 18 who were admitted to our hospital were included in the study. Results: The study included 226 patients. According to the World Health Organization staging, 75(33.2%) patients, according to the staging of Siddiqi et al., 67 (29.7%) patients progressed. In the ROC analysis performed to predict mortality, AUC value for D-dimer was found to be 82.25% (95%CI 74.8%-89.71%). When the cut-off value for D-dimer was accepted as ≥3.25mg/L, specificity was 94.15%, correctly classified rate 88.5%, positive likelihood ratio as (LR):5.69, negative LR:0.71. Conclusion: As a result, similar to the Chinese cohorts, elevated D-dimer measurements increase disease progression and mortality in Turkish patients with COVID-19. D-dimer levels of 3.25 mg/L and above, strongly determine the risk of increased mortality in the Turkish Caucasian ethnic group.
