New markers in chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD), a global healthcare and socioeconomic burden, is a multifaceted respiratory disorder that results in substantial decline in health status and life quality. Acute exacerbations of the disease contribute significantly to increased morbidity and mortality. Consequently, the identification of reliable and effective biomarkers for rapid diagnosis, prediction, and prognosis of exacerbations is imperative.

Exploring S100A8/A9, neopterin, and MMP3 in familial Mediterranean fever.

Familial Mediterranean fever (FMF) is characterized by inflammatory attacks due to overactivation of pyrin inflammasome. This study aimed to investigate the reliability of S100A8/A9, neopterin, and matrix metalloproteinase 3 (MMP3) at monitoring subclinical inflammation and disease activity, and at differentiating FMF attacks from appendicitis, the most common misdiagnosis among FMF patients. Blood samples (n = 75), comprising from FMF patients during an attack (n = 20), the same FMF patients during the attack-free period (n = 14), patients with appendicitis (n = 24), and healthy volunteers (n = 17) were obtained.

Clinical assessment and short-term mortality prediction of older adults with altered mental status using RASS and 4AT tools.

Background: Altered mental status (AMS) in older adults is a common reason for admission to emergency departments (EDs) and usually results from delirium, stupor, or coma. It is important to proficiently identify underlying factors and anticipate clinical outcomes for those patients.

Aim: The primary objective of this study was to reveal and compare the clinical outcomes and etiologic factors of older patients with delirium, stupor, and coma.

Geriatric mortality risk factors in emergency department for non-traumatic abdominal pain.

Objectives: The study aimed to determine the factors affecting the mortality of geriatric patients presenting to the emergency department with non-traumatic abdominal pain, as well as the associations of these factors with mortality.

Background: With the increasing number of elderly patients, early recognition of patients with risk-bearing diagnoses is crucial.

Methods: This prospective cross-sectional study included 466 patients over 65 years of age who were admitted to THE emergency department of a tertiary hospital and consented to participate.

Assessment of the role of neutrophil extracellular traps in SARS-CoV-2 pneumonia.

Background: Abnormal neutrophil extracellular traps are associated with lung diseases, thrombosis, increased mucosal secretion in the airways. The aim of this study is to evaluate the possible place of the most specific NETosis marker Cit-H3 protein in diagnostic algorithms by revealing its relationship with the severity, mortality and prognosis of SARS-CoV-2 pneumonia.

Patients And Methods: Patients (n = 78) who applied to the Emergency Department between March 11, 2020 and June 10, 2020, with positive SARS-CoV-2 polymerase chain reaction (PCR) test and lung involvement were included in the prospective study.

ACE2 and ANGII levels in patients with COVID-19 based on thoracic tomography findings and PCR test results.

Introduction: Reverse transcriptase polymerase chain reaction tests and thoracic tomography have been widely employed in the diagnosis of the disease, but doubts about their sensitivity still persist. Also there are controversial results about ACE2 and AngII levels according to the severity of disease. In this study, we aimed to analyze the ACE2 and AngII levels in patients with suspected COVID-19 based on polymerase chain reaction test results and thoracic tomography findings and to examine their relationship with disease severity.

Role of plasma angiotensin II and angiotensin-converting enzyme 2 levels on prognosis and mortality in hypertensive patients with COVID-19.

SARS-CoV-2 requires angiotensin-converting enzyme 2 (ACE2) to enter the cell. In our study, we aimed to investigate the role of angiotensin-converting enzyme 2 and angiotensin II plasma levels on prognosis and mortality in patients with isolated hypertension, patients with chronic diseases in addition to hypertension and patients with COVID-19 without comorbidities, in accordance with the use of renin-angiotensin-aldosterone system inhibitor. In the study, patients diagnosed with COVID-19 were divided into three groups.

Efficacy of Serum Angiotensin II Levels in Prognosis of Patients With Coronavirus Disease 2019.

Objectives: We aimed to determine serum angiotensin II levels in patients with coronavirus disease 2019 infection and to investigate the effect of these levels on the prognosis of the disease.

Design: The study was planned prospectively and observationally.

Setting: The study was conducted in a tertiary university hospital.

Tacrolimus-Induced Vision Loss in a Renal Transplant Patient: Posterior Reversible Encephalopathy Syndrome.

Posterior reversible encephalopathy syndrome is a rare and serious neurologic adverse effect of calcineurin inhibitors. The pathophysiology of this clinical entity is still unclear. Impaired cerebral autoregulation and endothelial dysfunction are thought to be the main pathologic processes.

Bleeding Complications in Warfarin-Treated Patients Admitted to the Emergency Department.

Background: Increased use of warfarin for the treatment and prophylaxis of many diseases has increased the frequency of adverse events. Emergency departments (EDs) are the first places where early interventions for bleeding and other complaints related to warfarin use are performed. This study assessed the characteristics of patients receiving warfarin and the risk factors for bleeding complication among those admitted to the ED.
