Contrasting Weather and Stocking Effects on Initial Coppice Response in Brazil.

In plantations, coppice rotations often yield less than initial rotations. The TECHS project (Tolerance of Clones to Hydric, Thermal and Biotic Stresses) studied short rotation coppicing across a 3000 km gradient. The main objective of this work was to compare the survival, sprouting, and initial growth of clones managed and to examine factors that might influence the productivity of the coppice rotation: climate, genotypes, and stocking.

Coronary angiography and percutaneous coronary intervention after transcatheter aortic valve replacement: Feasibility in clinical practice.

Introduction And Objective: Coronary artery disease is highly prevalent among patients with severe aortic stenosis who undergo transcatheter aortic valve replacement (TAVR). As indications for TAVR are now expanding to younger and lower-risk patients, the need for coronary angiography (CA) and percutaneous coronary intervention (PCI) during their lifetime is expected to increase. The objective of our study was to assess the need for CA and the feasibility of re-engaging the coronary ostia after TAVR.

Staging cardiac damage in patients with aortic regurgitation.

The impact of "downstream" pathophysiological cardiac consequences in aortic regurgitation patients were not well established. The aim of our study was to validate a staging system built for severe aortic stenosis in a large real-world cohort of aortic regurgitation (AR) patients, evaluating the prevalence of different stages of cardiac damage and assess its prognostic impact. Clinical, echocardiographic and outcome data of patients with moderate-severe AR who underwent transthoracic echocardiography between January/2014 and September/2019 were retrospectively analysed.

Higher coronary artery calcium score is associated with increased risk of atrial fibrillation recurrence after catheter ablation.

Background: Coronary artery calcium score (CACS) is associated with an increased risk of atrial fibrillation (AF) development, but scarce data are available regarding the impact on AF recurrence. This study aims to assess the impact of CACS on AF recurrence following catheter ablation.

Methods: Retrospective study of patients with AF undergoing cardiac computed tomography (CCT) before ablation (2017-2019).

Clinical relevance of the blanking period on late recurrence after catheter ablation of atrial fibrillation.

Introduction: Recurrence of atrial fibrillation (AF) within the blanking period after catheter ablation (CA) is traditionally classified as a transient and benign event. However, recent findings suggest that early recurrence (ER) is associated with late recurrence (LR), challenging the predefined "blanking period". We aimed to determine the clinical and procedural predictors of ER and LR after CA and establish the risk of LR in patients who experience ER.

Catastrophic presentation of peripartum cardiomyopathy: a case report of a challenging diagnosis.

Background: Peripartum cardiomyopathy (PPCM) usually affects women in the last month of pregnancy or in the first months following delivery and typically presents with signs and symptoms of heart failure (HF), although catastrophic presentations may be the initial manifestation.

Case Summary: A 36-year-old woman reported intense fatigue that began after delivery. Three months following delivery, she suffered a cardiac arrest at home, in shockable rhythm, with a total estimated time of 70 min before return of spontaneous circulation.

The First Optimization Process from Cultivation to Flavonoid-Rich Extract from Lam. Leaves in Brazil.

Flavonoids are significant antioxidant and anti-inflammatory agents and have multiple potential health applications. is globally recognized for its nutritional and pharmacological properties, correlated to the high flavonoid content in its leaves. However, the bioactive compounds found in plants may vary according to the cultivation, origin, season, and extraction process used, making it difficult to extract reliable raw material.

Fighting the pandemic with collaboration at heart: Report from cardiologists in a COVID-19-dedicated Portuguese intensive care unit.

Introduction And Objectives: The coronavirus disease 2019 (COVID-19) spread quickly around the world. Although mainly a respiratory illness, there is growing interest in non-respiratory manifestations, particularly cardiovascular ones. At our center, mobilization of cardiologists with intensive care training was needed.

Incessant Atrial Tachycardia: Problem Solving With Minimally Invasive Surgery.

A 35-year-old female with sarcoidosis sought medical attention due to palpitations. The ECG showed an atrial tachycardia (AT), apparently originating in the left atrium. A 24-hour Holter monitoring revealed AT to be present during the entire day.

COAPT-Like Profile Predicts Long-Term Outcomes in Patients With Secondary Mitral Regurgitation Undergoing MitraClip Implantation.

Objectives: The aim of this study was to evaluate whether fulfilling COAPT (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients With Functional Mitral Regurgitation) criteria identifies patients with better outcomes after MitraClip treatment for secondary mitral regurgitation (SMR).

Background: To date, COAPT is the only trial showing a prognostic benefit of MitraClip implantation compared with conservative management.

Methods: Three hundred four patients with SMR undergoing MitraClip placement in addition to optimal medical therapy at 3 European centers were analyzed.
