Abstract
Abstract
Background and purpose
Women at increased surgical risk have been shown to have better outcomes with transcatheter aortic valve implantation (TAVI) as compared to surgical valve replacement (SAVR). With the scope of TAVI moving into low-surgical risk patients we aimed to update the current literature to include the new low-risk randomized controlled trial data in investigating outcomes by sex.
Methods
We systematically searched MedlineOVID, PubMed, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov and reference lists for relevant randomised controlled trials (RCTs) comparing TAVI to SAVR published prior to October 7th 2019. Data extraction was performed by two independent authors and included trial design details, baseline characteristics and outcome data stratified by sex. Risk of bias was assessed using the Cochrane Risk of Bias 2 tool. Quantitative synthesis of pooled data was performed using Mantel-Haenszel fixed or random effects model. Q-statistic and the I2 test were used for assessment of heterogeneity.
Results
Our search yielded eight RCTs included in the final quantitative synthesis. The overall pooled cohort was 8,040, of whom 41.4% were female. Women had significantly lower rates of one-year all-cause mortality and one-year composite endpoint with TAVI as compared to SAVR. The selective mortality benefit with TAVI over SAVR in women did not persist to five-years. At 30-days, women demonstrated lower rates of major bleeding and acute kidney injury following TAVI compared to SAVR. For men, these outcomes were similar regardless of type of intervention. Both sexes were at increased risk of major vascular complications with TAVI as compared to SAVR, however women demonstrated nearly double the odds of major vascular complication with TAVI compared to men.
Conclusion
Our updated meta-analysis demonstrates that at one-year women undergoing TAVI have significantly lower mortality and better safety outcomes compared to those undergoing SAVR. These benefits are not seen in men. In the new low-risk era, these results are ever more important for guiding appropriate patient selection.
Composite endpoint at one-year

Abstract
The global coronavirus disease (COVID-19) pandemic poses an unprecedented stress on healthcare systems internationally. These Health system-wide demands call for efficient utilisation of resources at this time in a fair, consistent, ethical and efficient manner would improve our ability to treat patients. Excellent co-operation between hospital units (especially intensive care unit [ICU], emergency department [ED] and cardiology) is critical in ensuring optimal patient outcomes. The purpose of this document is to provide practical guidelines for the effective use of interventional cardiology services in Australia and New Zealand. The document will be updated regularly as new evidence and knowledge is gained with time. Goals Considerations.

Abstract
Nd-Fe-B permanent magnets are a strategic material for a number of emerging technologies. They are a key component in the most energy efficient electric motors and generators, thus, they are vital for energy technologies, industrial applications and automation, and future forms of mobility. Rare earth elements (REEs) such as neodymium, dysprosium and praseodymium are also found in waste electrical and electronic equipment (WEEE) in volumes that grow with the technological evolution, and are marked as critical elements by the European Commission due to their high economic importance combined with significant supply risks. Recycling could be a good approach to compensate for the lack of rare earths (REs) on the market. However, less than 1% of REs are currently being recycled, mainly because of non-existing collection logistics, lack of information about the quantity of RE materials available for recycling and recycling-unfriendly product designs. To improve these lack of information, different waste streams of electrical and electronic equipment from an industrial recycling plant were analyzed in order to localize, identify and collect RE permanent magnets of the Nd-Fe-B type. This particular type of magnets were mainly found in hard disk drives (HDDs) from laptops and desktop computers, as well as in loudspeakers from compact products such as flat screen TVs, PC screens, and laptops. Since HDDs have been investigated thoroughly by many authors, this study focusses on other potential Nd-Fe-B resources in electronic waste. The study includes a systematic survey of the chemical composition of the Nd-Fe-B magnets found in the selected waste streams, which illustrates the evolution of the Nd-Fe-B alloys over the years. The study also provides an overview over the types of magnets integrated in different waste electric and electronic equipment.
