State of the art modelling for the Black Sea ecosystem to support European policies.

The Black Sea is affected by numerous anthropogenic pressures, such as eutrophication and pollution through coastal and river discharges, fisheries overexploitation, species invasions, and the impacts of climate change. Growing concerns regarding the cumulative effects of these pressures have necessitated the need for an ecosystem approach to assessing the state of this basin. In recent years, the European Commission-JRC has developed a scientific and modelling tool, the Blue2 Modelling Framework with the aim of exploring the consequences of EU management and policy options on marine ecosystems.

A retrospective analysis of patients who underwent tracheal resection and end-to-end anastomosis surgery for benign tracheal stenosis, over a 10-year period.

Introduction: Laryngotracheal stenosis encompasses a diverse range of diagnoses, encompassing complete or partial narrowing of various subgroups of the upper airways, including the laryngeal structures and trachea, due to pathological scar formation. This increasingly prevalent pathology is of significant importance due to its potential for life-threatening consequences. Among the defined treatment modalities, tracheal resection and end-to-side anastomosis remain a valuable therapeutic alternative in appropriate indications.

Comparison of Early Warning Scores in Determining the Prognosis of COVID-19 Patients.

Objective:  To compare the effectiveness of early warning score systems in predicting 30-day poor outcomes in Coronavirus Disease (COVID-19) patients admitted to the emergency department.

Study Design: Descriptive study. Place and and Duration of the Study: Fatih Sultan Mehmet Education and Research Hospital, Istanbul, Turkiye, from March 2020 to March 2021.

Ecological indicators reveal historical regime shifts in the Black Sea ecosystem.

Background: The Black Sea is one of the most anthropogenically disturbed marine ecosystems in the world because of introduced species, fisheries overexploitation, nutrient enrichment pollution through river discharge, and the impacts of climate change. It has undergone significant ecosystem transformations since the 1960s. The infamous anchovy and alien warty comb jelly shift that occurred in 1989 is the most well-known example of the drastic extent of anthropogenic disturbance in the Black Sea.

Uncovering ecological regime shifts in the Sea of Marmara and reconsidering management strategies.

Ecosystem regime shifts can alter ecosystem services, affect human well-being, and trigger policy conflicts due to economic losses and reductions in societal and environmental benefits. Intensive anthropogenic activities make the Sea of Marmara ecosystem suffer from nearly all existing available types of ecosystem pressures such as biological degradation, exposure to hydrological processes, nutrient and organic matter enrichment, plastic pollution, ocean warming, resulting in deterioration of habitats. In this study, using an integrated ecosystem assessment, we investigated for the first time the historical development and ecosystem state of the Sea of Marmara.
