Associations of diagnostic awareness with psychosocial symptoms and survival time in patients with advanced lung cancer.

Objective: Disclosing the diagnosis of lung cancer to patients is an issue, especially in the Middle East where cultural factors may prohibit disclosure from being done. The psychosocial consequences of diagnostic awareness and its impact on life expectancy of disclosure are an important issue that may influence this decision. The present study evaluated the effects of diagnostic awareness on psychosocial symptomatology and survival time in advanced lung cancer patients in Turkey.

Diagnostic and prognostic values of serum Selenoprotein P and soluble St2 levels in pulmonary embolism.

Aim: Pulmonary Thromboembolism (PTE) occurs as a result of occlusion of one or more of the pulmonary artery branches by thrombus and is an important cause of right heart failure and pulmonary hypertension. Selenoprotein P (SePP) and soluble suppression of tumorigenicity 2 protein (sST2) are two new biomarkers that have previously been the subject of various studies in heart failure. The aim of this study was to determine the diagnostic and prognostic potential of SePP and soluble sST2 levels in patients with acute PTE.

Analysis of post-COVID symptoms and predisposing factors for chronic post-COVID syndrome.

Introduction: While there is sufficient information about acute COVID-19, which can cause a multisystemic and fatal disease, post-COVID syndrome and risk factors for this condition remain poorly known. We aimed to identify postCOVID symptoms and risk factors for chronic post-COVID syndrome through this study.

Materials And Methods: This prospective cross-sectional study was conducted on 254 out of 384 COVID-19 patients admitted to our COVID-19 polyclinic between February and April 2021.

A rare case of rapidly progressive Tracheobronchopathia Osteochondroplastica.

Tracheobronchopathia Osteochondroplastica (TO) is a rare benign disorder that is seldom progressive. Here, we report a case diagnosed with TO in our hospital. Bronchoscopy revealed multiple cartilaginous and ossifying nodules that are diagnostic for TO.

A rare case series of HIV-negative patients with early relapsing cervical tuberculosis lymphadenitis.

Most patients with early recurrent tuberculous lymphadenitis (RTL) can be overlooked due to the paucibacillary character of Mycobacterium tuberculosis complex (MTBC) causing difficulty in the differential diagnosis. Here, we present three cases with early RTL that occurred after completing pulmonary tuberculosis (TB) therapy with a cure, and that improved by early diagnosis and therapy. A 30-year-old migrant male, HIV-negative patient, who had used immunosuppressive drugs for Crohn's disease presented to the TB outpatient clinic with a new anterior cervical lymph node enlargement.

Prognostic predictors for mortality of patients with COVID-19 in an intensive care unit.

Introduction: Fatality due to COVID-19 continues to be a challenge. Timely identification of critical COVID-19 patients is crucial for their close clinical follow-up and treatment. We aimed to identify the mortality predictors of critical COVID-19 patients.

Broncholithiasis mimicking lung cancer.

A 64-year-old female patient was admitted to our outpatient clinic with pleuritic chest pain, non-productive cough, and dyspnea. She expectorated three stones (lithoptysis) before bronchoscopy. She underwent positron emission tomography-computed tomography, which revealed a hyper metabolic mass in the right upper lobe of her lung.

Coexistence of Multiple Pulmonary Sclerosing Pneumocytoma and Scleroderma-Rheumatoid Arthritis Overlap Syndrome: A Case Report.

Pulmonary sclerosing pneumocytoma is a rare, low-grade pulmonary tumor observed as unilateral or bilateral multiple nodules at a rate of 4%-5%. Among the autoimmune connective tissue disorders, those most commonly associated with lung malignancies are sclero- derma and rheumatoid arthritis. In this study, we report a rare case of a 55-year-old middle-aged Asian woman with slow-growing bilat- eral multiple pulmonary sclerosing pneumocytoma and scleroderma-rheumatoid arthritis overlap syndrome.

Lifestyle Changes and Exacerbation Frequency of COPD in Times of the Pandemic.

Objective: The objective of this study is to analyze chronic obstructive pulmonary disease exacerbation rates and the effect of patients' behavioral changes on the exacerbations during the pandemic.

Material And Methods: This study was conducted in a reference hospital for chest diseases and patients who were hospitalized with an exacerbation of chronic obstructive pulmonary disease between March 11, 2019, and March 11, 2020, were designated. Patients' chronic obstructive pulmonary disease exacerbations requiring emergency department visits and/or hospitalization were com- pared between the pre-pandemic and pandemic periods.

Hyponatremia is an independent predictor of emergency department revisits in acute exacerbation of COPD.

Introduction: Hyponatremia is shown to prolong hospitalization and increase mortality. The role of hyponatremia in chronic obstructive pulmonary disease is widely studied with a focus on hospitalized patients.

Objectives: To investigate whether hyponatremia increases the probability of re-exacerbations in non-hospitalized patients with acute exacerbations of chronic obstructive pulmonary disease (AECOPD).

Prognostic significance of ERCC1 expression in resected non small cell lung carcinoma.

Background And Aim: The effects of DNA repair pathway on survival were assessed by measuring the tumoral excision repair cross complementation 1 (ERCC1) expression in patients with resected non-small cell lung carcinoma (NSCLC). We aimed to determine the prognostic and predictive significance of ERCC1 in patients with completely resected NSCLC.

Methods: Immunohistochemistry (IHC) was used to assess the expression of ERCC1 in resected lung tumor samples obtained from 98 patients untreated without pre- or post-operative chemotherapy and/or radiotherapy.

Prognostic value of epidermal growth factor receptor expression in operable non-small cell lung carcinoma.

Background And Aim: Increased expression of the epidermal growth factor receptor (EGFR) in non-small cell lung cancer (NSCLC), supporting the tumor growth by a possible endocrine mechanism, affects patient survival negatively. We designed a study to test EGFR expression by immunohistochemistry (IHC) in resected stage I-II NSCLC and to correlate its overexpression with survival.

Methods: EGFR expression was evaluated in 98 consecutive NSCLC patients after complete resection (53 squamous cell carcinomas, 40 adenocarcinomas, 5 large cell carcinomas: stage I, 57 (58%) and stage II, 41 (42%).
