Article Synopsis
- The study investigates the effects of red blood cell (RBC) transfusion on short-term mortality in patients undergoing transapical transcatheter aortic valve implantation (TA-TAVI), where bleeding is common.
- Out of 11,265 TAVI participants, 548 had TA-TAVI, with 209 receiving RBC transfusions, and the study found a significant association between transfusion and increased 30-day mortality.
- The research concluded that RBC transfusion independently predicts higher short-term mortality in TA-TAVI patients, regardless of other factors like major bleeding and kidney injury.
Article Synopsis
- Dialysis is a serious but rare complication following transcatheter aortic valve replacement, and researchers analyzed the TRITAVI registry to develop a clinical score for assessing this risk.
- They identified various preprocedural factors (like male sex, diabetes, and anemia) and procedural features (like contrast volume and need for transfusion) that contribute to the risk, resulting in two scoring systems (TRITAVIpre and TRITAVIpost) which demonstrated strong predictive power.
- The study confirmed that the need for dialysis significantly increases mortality rates, emphasizing the importance of the developed scores in predicting dialysis risk before the procedure.
Aim: to compare a conventional primary reperfusion strategy with a primary unloading approach before reperfusion in preclinical studies. Methods: we performed a meta-analysis of preclinical studies. The primary endpoint was infarct size (IS).

However, it remains unclear how this phenomenon differentially affects particular targets expressing specific drinking responses depending on the perinatal conditions. The main goal of the present study was to compare the dipsogenic responses induced by different thirst models as a function of two perinatal manipulation models, defined by the maternal free access to hypertonic sodium solution and a partial aortic ligation (PAL-W/Na) or a sham-ligation (Sham-W/Na).

This study aimed to translate and confirm the factor structure of the Evidence-Based Practice Attitude Scale (EBPAS-15) survey in Brazilian Portuguese with the goal of examining providers' perspective about EBPIs.
Methods: We translated and back translated the EBPAS-15 from English to Brazilian Portuguese.
