Stanford A aortic dissection 40 years after aortic valve replacement with a Starr-Edwards caged-ball prosthesis: a case report.

Stanford A aortic dissection is one of the most devastating acute medical conditions due to its high morbidity and mortality. We describe a 77-year-old male patient with a medical history of surgical aortic valve replacement with a still functioning Starr-Edwards caged-ball valve 40 years prior. The patient was promptly diagnosed with an ascending aortic aneurysm and dissection, and an emergency Bentall procedure in deep hypothermic circulatory arrest was performed.

Multi-Center Fetal Brain Tissue Annotation (FeTA) Challenge 2022 Results.

Segmentation is a critical step in analyzing the developing human fetal brain. There have been vast improvements in automatic segmentation methods in the past several years, and the Fetal Brain Tissue Annotation (FeTA) Challenge 2021 helped to establish an excellent standard of fetal brain segmentation. However, FeTA 2021 was a single center study, limiting real-world clinical applicability and acceptance.

Long-Term Self-Management of Vaginal Cube Pessaries Can Improve Sexual Life in Patients with Pelvic Organ Prolapse, Results from a Secondary Analysis.

Introduction And Hypothesis: Currently, little is known about how daily self-management of cube pessaries influences sexual function. We hypothesized that removing the cube pessary prior to sexual activity did not negatively influence the sexual function, and pessary self-care did not lead to a deterioration of sexual wellbeing.

Methods: We conducted a planned secondary analysis of a prospective cohort study in which 214 patients with symptomatic pelvic organ prolapse (stage 2+) were enrolled (2015).

Socioeconomic determinants of environmental efficiency: the case of the European Union.

The study's main objective is to assess and evaluate the models of socioeconomic determinants of environmental efficiency in the European Union countries from 2010 to 2018. The two-step data envelopment analysis is implemented, using both constant and variable returns to scale assumption. Moreover, the results of the model of environmental efficiency determinants from four areas-tourism, circular economy, energy and resources use and quality of life-are presented.

Return to the New Normal: Empirical Analysis of Changes in E-Consumer Behavior during the COVID-19 Pandemic.

The global pandemic caused by the new coronavirus has largely changed established business practices. The aim of this study is to present the results of eighteen months of intensive research into the effects of the pandemic on e-consumer behavior. In one of the most active e-commerce markets in Europe, the Czech Republic, we analyzed a sample of more than one and a half million Facebook users in terms of their C2B interactions on the B2C activities of the five major e-commerce market players.
