: Hereditary angioedema (HAE) is characterized by unpredictable skin and mucosal angioedema attacks. We aimed to find the frequency of sexual-activity-triggered attacks (STAs) and understand how the sexual life of HAE with C1-inhibitor deficiency (HAE-C1INH) patients is affected. : Adult HAE-C1INH patients were included in this cross-sectional study, which started in March 2020.

Background: Hereditary angioedema is a rare disorder characterized by episodic, potentially life-threatening swelling caused by kallikrein-kinin dysregulation. Long-term prophylaxis can stabilize this system. Donidalorsen, an antisense oligonucleotide, specifically reduces prekallikrein expression.

Background Although there are many studies on violence against physicians in the literature, there are few studies on violence against physicians working in intensive care units (ICUs). We aimed to investigate the frequency, type and underlying factors of violence against physicians working in ICUs in Turkey in the past 1 year. Methods We collected data by sending a questionnaire about violence against physicians working in ICUs via e-mail and WhatsApp between 1 and 15 May 2022.

For patients monitored in intensive care units in the aftermath of a cardiac arrest, one of the well-established difficulties of care after resuscitation is the ability to perform the necessary prognostic assessments as accurately and early as possible. Although current guidelines include algorithms to determine prognosis, there are still missing links and uncertainties. Biomarkers obtained from peripheral blood are generally non-invasive and easy to obtain.

Background/aim: This study aimed to investigate the effects of oxygen therapy using a high flow nasal cannula (HFNC) on patients diagnosed with COVID-19 Acute Respiratory Distress Syndrome (C-ARDS) by utilizing electrical impedance tomography (EIT)-based parameters.

Materials And Methods: Oxygen therapy was administered to the patients at two different flow rates and two different positions: T0-baseline measurements were taken in the supine position before any therapy was initiated. T1-HFNC was administered in the supine position with a flow rate of 30 L/min.

Background: Hereditary angioedema with C1 inhibitor deficiency (HAE-C1INH) is caused by dysfunctional C1-INH protein due to mutations in the SERPING1 gene encoding C1-INH. Marfan syndrome is a genetic connective tissue disease that affects the cardiovascular and ocular systems along with the skeletal system. In this case, we present the successful treatment of post-pericardiotomy syndrome unresponsive to classical therapy, which has not been described in the literature.

Aim Of The Study: To investigate the disease-specific score and improve the existing scores to better determine the prognosis of patients after liver transplantation (LT). For this purpose, we evaluated the relationship of prognostic scores with 30-day mortality after LT. In addition, we planned to investigate whether the mean platelet volume/platelet count (MPR) would contribute to score improvement.

This retrospective cohort study deals with evaluating severity of COVID-19 cases on the first symptoms and blood-test results of infected patients admitted to Emergency Department of Koc University Hospital (Istanbul, Turkey). To figure out remarkable hematological characteristics and risk factors in the prognosis evaluation of COVID-19 cases, the hybrid machine learning (ML) approaches integrated with feature selection procedure based Genetic Algorithms and information complexity were used in addition to the multivariate statistical analysis. Specifically, COVID-19 dataset includes demographic features, symptoms, blood test results and disease histories of total 166 inpatients with different age and gender groups.

Objective: To determine the prevalence of and the risk factors for Potentially Inappropriate Medication (PIM), the drug groups most commonly evaluated as PIMs in elderly patients in the ICUs by using 2019 Beers Criteria, STOPP version 2 (v2) Criteria and EU(7)-PIM List. The relation between mortality rate and length of ICU stay with PIMs was also examined.

Methods: This was a cross sectional study conducted on patients aged ≥65 years, treated in ICUs (n = 139) between June 8, 2020, and January 11, 2021.

Article Synopsis
  • - The study aimed to gather data on the characteristics of intensive care units (ICUs) in Turkey through a nationwide point prevalence survey conducted by the Turkish Thoracic Society.
  • - Data from 67 ICUs revealed that 76.1% operated under a closed system, with 35.8% classified as Level of Care (LOC) 2 and 64.2% as LOC 3, indicating a range of critical care capacity.
  • - The findings highlighted a significant need for more specialized physicians and nurses in ICUs, particularly during nighttime, although the percentage of certified ICU nurses was seen as relatively adequate, with aspirations for full certification.
