Impact of Pacemaker Implantation After Transcatheter Aortic Valve Replacement on Long-Term Survival in Patients With Bicuspid Aortic Valve.

Limited data are available about the impact of permanent pacemaker (PPM) implantation on long-term survival in patients with a bicuspid aortic valve (BAV) and severe aortic stenosis (AS) treated with transcatheter aortic valve replacement (TAVR). We aimed to evaluate the long-term clinical outcomes of patients with BAV with AS who underwent periprocedural PPM implantation after TAVR with a self-expandable prosthesis. Data from patients with BAV and severe AS who underwent TAVR between April 2009 and January 2022 and followed in the framework of the One Hospital ClinicalService-CoreValve Project were collected.

Non-pegylated liposomal doxorubicin in older adjuvant early breast cancer patients: cardiac safety analysis and final results of the COLTONE study.

Aims: To explore the cardiac safety of adjuvant Non-Pegylated Liposomal Doxorubicin (NPL-DOX) plus Cyclophosphamide (CTX) followed by weekly Paclitaxel, in elderly women (≥ 65 years) with high-risk breast cancer. Previously, we described no symptomatic cardiac events within the first 12 months from starting treatment. We now reported the updated results after a median follow-up 76 months.

Outcomes of Patients With Very Severe Aortic Stenosis Treated With Transcatheter Aortic Valve Implantation.

Symptoms of aortic stenosis (AS) are not proportional to its severity and patients with very severe AS (VSAS) remain asymptomatic for a long time. The appropriate time for intervention in patients with VSAS and the effects of transcatheter aortic valve implantation (TAVI) on left ventricular hypertrophy (LVH) remain debated. Our aim was to compare the procedural and 30-day outcomes of TAVI between patients with VSAS and patients with severe AS (SAS) and the changes in LVH.

Post-anesthetic CPS and EQUUS-FAP scores in surgical and non-surgical equine patients: an observational study.

Background: Equine pain scoring may be affected by the residual effect of anesthetic drugs.

Objectives: To compare pain scores in the hours immediately following anesthetic recovery to baseline pre-anesthetic scores in equine patients undergoing surgical and non-surgical procedures.

Study Design: Clinical observational study.

Prognostic Significance of Flail Mitral Leaflet in Transcatheter Edge-to-Edge Repair for Primary Mitral Regurgitation.

Despite the growing experience with MitraClip in the broad spectrum of mitral regurgitation (MR), limited data are available regarding the independent prognostic role on survival of different mitral regurgitation etiology subtypes. We sought to evaluate the impact of flail leaflet etiology in a large series of patients with primary MR (PMR) who underwent MitraClip treatment. The study included 588 patients with significant PMR from the multicenter GIOTTO (Italian Society of Interventional Cardiology [GIse] registry Of Transcatheter treatment of mitral valve regurgitaTiOn), stratified into 2 groups according to MR etiology: flail (n = 300) and flail (n = 288).

Evaluation of wave configurations in corrugated boards by experimental analysis (EA) and finite element modeling (FEM): the role of the micro-wave in packaging design.

The aim of this paper is to study the mechanical behavior of corrugated board boxes, focusing attention on the strength that the boxes are able to offer in compression under stacking conditions. A preliminary design of the corrugated cardboard structures starting from the definition of each individual layer, namely the outer liners and the innermost flute, was carried out. For this purpose, three distinct types of corrugated board structures that include flutes with different characteristics, namely the high wave (C), the medium wave (B), and even the micro-wave (E), were comparatively evaluated.

Animals: 29 healthy dogs.

Procedures: Dogs in the experimental group (n = 8) and dogs in the control group (21) were connected to an HHBC and a conventional rebreathing circuit, respectively.

Coenzyme Q10 + alpha lipoic acid for chronic COVID syndrome.

Chronic COVID syndrome is characterized by chronic fatigue, myalgia, depression and sleep disturbances, similar to chronic fatigue syndrome (CFS) and fibromyalgia syndrome.

A pharmacogenetic interaction analysis of bevacizumab with paclitaxel in advanced breast cancer patients.

To investigate pharmacogenetic interactions among VEGF-A, VEGFR-2, IL-8, HIF-1α, EPAS-1, and TSP-1 SNPs and their role on progression-free survival (PFS) in metastatic breast cancer (MBC) patients treated with bevacizumab plus first-line paclitaxel or with paclitaxel alone. Analyses were performed on germline DNA, and SNPs were investigated by real-time PCR technique. The multifactor dimensionality reduction (MDR) methodology was applied to investigate the interaction between SNPs.

Comparison of Traditional Lecture-Based Learning versus Interactive Electronic Book Learning in Veterinary Student Comprehension of Inhalant Anesthetic Administration, Uptake, and Elimination.

The administration, uptake, and elimination of inhalant anesthetics is a challenging topic in the veterinary curriculum, and lecture-based learning is often insufficient to ensure that students understand these concepts. We hypothesized that the use of an interactive electronic book (e-book) would enhance student comprehension of the material. Two sequential Doctorate of Veterinary Medicine student cohorts participated in a prospective controlled study.

Analysis of changes of cavity volumes in predefined directions of protein motions and cavity flexibility.

Dynamics of protein cavities associated with protein fluctuations and conformational plasticity is essential for their biological function. NMR ensembles, molecular dynamics (MD) simulations, and normal mode analysis (NMA) provide appropriate frameworks to explore functionally relevant protein dynamics and cavity changes relationships. Within this context, we have recently developed analysis of null areas (ANA), an efficient method to calculate cavity volumes.
