Article Synopsis
- The COVID-19 pandemic led to significant treatment delays for patients needing transcatheter aortic valve replacement (TAVR), with a marked decrease in procedure volumes during the first two waves of the pandemic.
- The study analyzed TAVR case data from 130 centers in 61 countries, finding a 15% drop in cases during the first wave and 7% in the second, particularly affecting regions like Africa, Central-South America, and Asia.
- Factors such as hospital type (private vs public), urban vs rural location, low procedure volumes, a country's socioeconomic status, and stringent public health measures contributed to these reductions, highlighting the need for improved public health policies for future health crises.
Inland waters are important components of the global carbon cycle as they regulate the flow of terrestrial carbon to the oceans. In this context, remote monitoring of Colored Dissolved Organic Matter (CDOM) allows for analyzing the carbon content in aquatic systems. In this study, we develop semi-empirical models for remote estimation of the CDOM absorption coefficient at 400 nm (a) in a tropical estuarine-lagunar productive system using spectral reflectance data.

However, limb recipients have a 6-fold greater rejection rate than solid organ transplant recipients, related in part to greater immunogenicity of the skin. Here, we report a detailed immunological and molecular characterization of individuals who underwent bilateral limb transplantation at our institution.

Introduction: Most patients with chronic cardiomyopathy of Chagas disease (CCCD) harbor a secondary cause of coronary microvascular dysfunction (CMD), for which there is no evidence-based therapy. We evaluated the impact of verapamil plus aspirin on symptoms and perfusion abnormalities in patients with CCCD and CMD.
Methods: Consecutive patients with angina pectoris, who had neither coronary artery obstructions nor moderate-severe left ventricular dysfunction (left ventricular ejection fraction > 40%) despite showing wall motion abnormalities on ventriculography, were referred for invasive angiography and tested for Chagas disease.
