Assessment regarding intramyocardial hemorrhage together with dark-blood T2*-weighted cardio magnet resonance.
It represents a significant evolution in the field and is expected to have broad application in clinical practice and research. In this review article we present the limitations of standalone intravascular imaging techniques, summarise the data supporting the value of multimodality imaging in clinical practice and research, describe the Novasight Hybrid IVUS-OCT system and highlight the potential utility of this technology in coronary intervention and in the study of atherosclerosis.For many decades, the severity of coronary artery disease (CAD) and the indication to proceed with either percutaneous coronary intervention (PCI) or surgical revascularization has been based on anatomically derived parameters of vessel stenosis, and typically on the percentage of lumen diameter stenosis (DS%) as determined by invasive coronary angiography (CA). However, it is currently a well-accepted concept that pre-specified thresholds of DS% have a weak correlation with the ischaemic and functional potential of an epicardial coronary stenosis. In this regard, the introduction of fractional-flow reserve (FFR) has represented a paradigm-shift in the understanding, diagnosis, and treatment of CAD, but the adoption of FFR into the clinical practice remains surprisingly limited and sub-standard, probably because of the inherent drawbacks of pressure-wirebased technology such as additional costs, prolonged procedural time, invasive instrumentation of the target vessel, and use of vaso-dilatory agents causing side effects for patients. For this reason, new modalities are under development or validation to derive FFR from computational fluid dynamics (CFD) applied to a three-dimensional model (3D) of the target vessel obtained from CA, intravascular imaging, or coronary computed tomography angiography. The purpose of this review is to describe the technical details of these anatomy-derived indices of coronary physiology with a special focus on summarizing their workflow, available evidence, and future perspectives about their application in the clinical practice.
Distal transradial access (dTRA) has been recently proposed as an innovative access for coronary procedures and a valuable alternative to conventional transradial access (cTRA). The aim of this study was to assess the safety of dTRA versus cTRA in patients undergoing percutaneous coronary angiography and intervention.

In this single-center randomized trial, consecutive patients admitted for stable cardiac condition or acute coronary syndrome (ACS) were assigned to dTRA or cTRA. The primary endpoint was an early discharge after transradial stenting of coronary arteries (EASY) grade ≥II access-site hematoma (ASH). Vascular access failure, radial artery occlusion (RAO) at hospital discharge , 30-day rates of death, myocardial infarction, stroke and bleeding not related to coronary artery bypass grafting were considered as secondary endpoints.

A total of 204 patients were included and randomized to dTRA (n=100) or cTRA (n=104). The two populations were similar, except for a higher percentage of ACS in the dTRA than in the cTRA group (38% versus 24%, P=0.022). The rate of EASY grade ≥II ASH was lower in dTRA than in cTRA patients, but the difference was not statistically significant (4% versus 8.4%, respectively, P=0.25). Vascular access failure was more frequent in dTRA patients than in cTRA patients (34% versus 8.7%, P<0.0001). We detected no case of RAO at hospital discharge and similar rates of 30-day adverse events in both groups.

DTRA is safe and feasible. When compared to cTRA, dTRA is technically more demanding and limited by more frequent crossover to an alternative vascular access.

north of Italy has been one of the most affected area in the world by the novel Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV2). The healthcare system has been overwhelmed by the huge number of patients in need of mechanical ventilation or intensive care, resulting in a delay of treatment of patients with acute coronary syndrome (ACS), due to a crash in STEMI networks and closure of a certain number of hub centers, and to a delay in patients' seeking for medical evaluation for chest pain or angina-equivalent symptoms.

in the Trentino region, a mountainous area with about 500,000 inhabitants, very close to Lombardy that was the epicenter of the pandemic in Italy, to avoid these dramatic consequences, we developed a new protocol tailored to our specificity to keep our institution, and above all the cath-lab, clean from the SARS-CoV-2 infection, to ensure full operativity for cardiologic emergencies.

Applying this protocol during the two months of the peak of the infection in Italy no one of the staff members of the cath-lab, the ICCU or the cardiology ward tested positive to nasal swab for SARS-CoV-2 and the same result was obtained for all the patients admitted to our units.

our real world experience shows that during the COVID-19 pandemic, quick activation of an appropriate protocol defining specific pathways for patients with a medical urgency is effective in minimizing healthcare personnel exposure and to preserve full operativity of the hub centers. This issue will be of a crucial importance, now that we are facing the second wave of the pandemic.

Left atrial appendage (LAA) closure represents a novel therapeutic chance for patients with contraindications to long-term anticoagulation therapy, such as those affected by Hereditary Hemorrhagic Telangiectasia (HHT) and atrial fibrillation (AF). Nevertheless, current experts' indications suggest the post-procedural administration of antithrombotic therapies to minimize the residual thromboembolic risk due to AF and to the need for device endothelialization. The aim of our study was to investigate the safety and effectiveness of LAA closure in preventing arterial thromboembolism in a very high-bleeding risk group, such as HHT patients, who are at risk not to tolerate even the mild post-procedural antithrombotic therapy usually recommended.

Eight HHT-affected patients with non-valvular AF, high-bleeding risk and/or known intolerance to antiplatelet and anticoagulant therapy were treated with interventional LAA occlusion with the Amplatzer™ Cardiac Plug™ and Amplatzer™ Amulet™ devices. Device implantation ntially life-saving alternative to lifelong anticoagulant therapy in HHT, as in other very high-bleeding risk patients.
Our study suggests that the percutaneous LAA closure in HHT patients with AF could be safe and effective in preventing arterial systemic thromboembolism, also in the presence of reduced or absent post-interventional antithrombotic treatment. LAA occluder implantation can represent a valid and potentially life-saving alternative to lifelong anticoagulant therapy in HHT, as in other very high-bleeding risk patients.
To determine whether renin-angiotensin system inhibitor (RASI) prescription is associated with better survival after transcatheter aortic valve implantation (TAVI), we performed the first meta-analysis of currently available studies.

To identify all studies reporting impact of RASI prescription on survival after TAVI, we searched PubMed, Web of Science, and Google Scholar through October 2019 We extracted adjusted (if unavailable, unadjusted) hazard ratios (HRs) with their confidence interval (CIs) of midterm (up to ≥6-month) allcause for RASI prescription from each study and combined study-specific estimates using inverse variance-weighted averages of logarithmic HRs in the random-effects model.

We identified 13 eligible studies with a total of 26,132 TAVI patients and included them in the present meta-analysis. None was a randomized controlled trial, 5 were observational studies comparing patients with versus without RASI prescription (including 3 propensity score matched studies), and 8 were observational studies investigating RASI prescription as one of covariates. The primary meta-analysis of all studies demonstrated that RASI prescription was associated with significantly lower midterm mortality (HR, 0.83; 95% CI, 0.76 to 0.92; P = 0.0002). Although we identified significant funnel plot asymmetry (P = 0.036 by the rank correlation test) suggesting publication bias, correcting for it using the trim-and-fill method did not substantially alter the result favoring RASI prescription (corrected HR, 0.85; 95% CI, 0.76 to 0.95; P = 0.004).

RASI prescription may be associated with better midterm survival after TAVI.

As a symptom is a subjective perception of patients, good symptom management requires the patients to actively talk to clinicians about their symptom experience and to effectively express concerns about treatment. It has been found that the patients displayed poor communication behaviors and lacked communication knowledge and skills in the oncology ward of a tertiary hospital in PR China, indicating the need for improvement. This project aimed to promote the cancer patients' symptom-related communication with clinicians in this hospital setting.

A baseline audit against six evidence-based audit criteria derived from best practice recommendations was conducted, utilizing the JBI Practical Application of Clinical Evidence System tool. Identification of facilitators and barriers to best practice was then carried out and strategies were implemented to overcome identified barriers. A postimplementation audit was undertaken to assess any improvement in practice.

The baseline audit showed that the nurses' compliance with best practice recommendations was unsatisfactory, with five out of six criteria recording 0% compliance. Strategies including nurse education, patient symptom assessment, patient education and use of communication tools were implemented. selleck kinase inhibitor The postimplementation audit showed significantly improved compliance in the nurses' practice with all best practice recommendations, with all audit criteria achieving at least 69% compliance.

The project achieved improved practice in patient communication promotion across all six audit criteria. However, further effort is needed to strengthen and maintain best practice. Patient symptom-related communication behavior should be measured in the future.

Oat has been widely accepted as a key food for human health. It is becoming increasingly evident that individual differences in metabolism determine how different individuals benefit from diet. Both host genetics and the gut microbiota play important roles on the metabolism and function of dietary compounds.

To investigate the mechanism of individual variations in response to whole-grain (WG) oat intake.

We used the combination of in vitro incubation assays with human gut microbiota, mouse and human S9 fractions, chemical analyses, germ-free (GF) mice, 16S rRNA sequencing, gnotobiotic techniques, and a human feeding study.

Avenanthramides (AVAs), the signature bioactive polyphenols of WG oat, were not metabolized into their dihydro forms, dihydro-AVAs (DH-AVAs), by both human and mouse S9 fractions. DH-AVAs were detected in the colon and the distal regions but not in the proximal and middle regions of the perfused mouse intestine, and were in specific pathogen-free (SPF) mice but not in GF mice. A kinetic study of humans fed oat bran showed that DH-AVAs reached their maximal concentrations at much later time points than their corresponding AVAs (10.
