Artificial Intelligence Prediction Model of Occurrence of Cerebral Vasospasms Based on Machine Learning.

Background:  Symptomatic cerebral vasospasms are deleterious complication of the rupture of a cerebral aneurysm and potentially lethal. The existing scales used to classify the initial presentation of a subarachnoid hemorrhage (SAH) offer a blink of the outcome and the possibility of occurrence of symptomatic cerebral vasospasms. Altogether, neither are they sufficient to predict outcome or occurrence of events reliably nor do they offer a united front.

Technical and Clinical Outcomes After Transcatheter Edge-to-Edge Repair of Mitral Regurgitation in Male and Female Patients: Is Equality Achieved?

Background: Currently, no clear impact of sex on short- and long-term survival following transcatheter edge-to-edge mitral valve repair (TEER) is evident, although no data are available on postprocedural life expectancy. Our aim was to assess sex-specific differences in outcomes of patients with mitral regurgitation (MR) treated by TEER.

Methods And Results: Short-term and 5-year outcomes in men and women undergoing TEER between 2011 and 2018 who were included in the large, multicenter, real-world MitraSwiss registry were analyzed.

Restoration of Life Expectancy After Transcatheter Edge-to-Edge Mitral Valve Repair.

Background: Survival data after mitral transcatheter edge-to-edge repair (TEER) are scarce, and its impact on predicted life expectancy is unknown.

Objectives: The aim of this study was to estimate the impact of TEER on postprocedural life expectancy among patients enrolled in the MitraSwiss registry through a relative survival (RS) analysis.

Methods: Consecutive TEER patients 60 to 89 years of age enrolled between 2011 and 2018 (N = 1140) were evaluated.

Transcatheter Aortic Valve Implantation by Intercostal Access: Initial Experience with a No-Touch Technique.

Background: Transcatheter aortic valve implantation (TAVI) is now a well-established therapeutic option in an elderly high-risk patient cohort with aortic valve disease. Although most commonly performed via a transfemoral route, alternative approaches for TAVI are constantly being improved. Instead of the classical mini-sternotomy, it is possible to achieve a transaortic access via a right anterior mini-thoracotomy in the second intercostal space.

Transcriptome signatures of wastewater effluent exposure in larval zebrafish vary with seasonal mixture composition in an effluent-dominated stream.

Wastewater treatment plant (WWTP) effluent-dominated streams provide critical habitat for aquatic and terrestrial organisms but also continually expose them to complex mixtures of pharmaceuticals that can potentially impair growth, behavior, and reproduction. Currently, few biomarkers are available that relate to pharmaceutical-specific mechanisms of action. In the experiment reported in this paper, zebrafish (Danio rerio) embryos at two developmental stages were exposed to water samples from three sampling sites (0.
