Ventilatory efficiency in long-term dyspnoeic patients following COVID-19 pneumonia.

Background: Long COVID is defined as persistency of symptoms, such as exertional dyspnea, twelve weeks after recovery from SARS-CoV-2 infection.

Objectives: To investigate ventilatory efficiency by the use of cardiopulmonary exercise testing (CPET) in patients with exertional dyspnea despite normal basal spirometry after 18 (T) and 36 months (T) from COVID-19 pneumonia.

Methods: One hundred patients with moderate-critical COVID-19 were prospectively enrolled in our Long COVID program.

Nutritional composition of ultra-processed plant-based foods in the out-of-home environment: a multi-country survey with plant-based burgers.

Ultra-processed plant-based foods, such as plant-based burgers, have gained in popularity. Particularly in the out-of-home (OOH) environment, evidence regarding their nutritional profile and environmental sustainability is still evolving. Plant-based burgers available at selected OOH sites were randomly sampled in Amsterdam, Copenhagen, Lisbon and London.

Standardizing PaO2 for PaCO2 in P/F ratio predicts in-hospital mortality in acute respiratory failure due to Covid-19: A pilot prospective study.

Introduction: Up to fifteen percent of patients with novel pandemic coronavirus disease (Covid-19) have acute respiratory failure (ARF). Ratio between arterial partial pressure of oxygen (PaO2) and fraction of inspired oxygen (FiO2), P/F, is currently used as a marker of ARF severity in Covid-19. P/F does not reflect the respiratory efforts made by patients to maintain arterial blood oxygenation, such as tachypnea and hyperpnea, leading to hypocapnia.

Arterial involvement in Fabry disease: state of the art and future diagnostic purposes.

Anderson-Fabry disease (FD) is a rare genetic, progressive, and multi-systemic condition, with X-linked inheritance. This is caused by pathogenic variants in the GLA gene, coding for the lysosomal enzyme called alpha-galactosidase A (aGLA), responsible for the cleavage of globotriaosylceramide (Gb3). The reduced or absent activity of aGLA causes the intracellular accumulation of Gb3, particularly in smooth and endothelial muscle cells, which causes cellular dysfunction.
