Systematic Review and Meta-analysis of Pirfenidone, Nintedanib, and Pamrevlumab for the Treatment of Idiopathic Pulmonary Fibrosis.
2020
Background: The comparative efficacy of pirfenidone, nintedanib, and pamrevlumab in slowing the rate of forced vital capacity (FVC) decline and mortality in patients with idiopathic pulmonary fibrosis (IPF) is unknown. Objective: To perform a systematic review and meta-analysis (MA) of these drugs for IPF. Methods: We searched CENTRAL, PubMed, EMBASE, ClincalTrials.gov, and the World Health Organization’s registry databases up to March 2020. Phase II/III randomized controlled trials in adults with IPF were eligible. The random-effect model was implemented calculating the effect size and respective 95% CI as Cohen’s d for change from baseline FVC (in percentage predicted and liters) and odds…
Inspiratory and Lower-Limb Strength Importance in Mountain Ultramarathon Running. Sex Differences and Relationship with Performance
2020
The study was aimed at comparing lower-limb strength and respiratory parameters between male and female athletes and their interaction with performance in a 107 km mountain ultramarathon. Forty seven runners (29 males and 18 females

Noninvasive Positive Pressure Ventilation in Amyotrophic Lateral Sclerosis
2010
Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease of unknown origin that affects approximately 1.5 individuals per 100,000 every year; usually, these individuals are between 55 and 75 years of age [1]. ALS causes progressive weakness of voluntary muscle groups, including respiratory ones, and respiratory failure or pneumonia related to respiratory muscle weakness is the most frequent cause of death.
Clinical Development of Mepolizumab for the Treatment of Severe Eosinophilic Asthma: On the Path to Personalized Medicine.
2021
The development of mepolizumab, an anti-IL-5 monoclonal antibody for the treatment of severe eosinophilic asthma, is an example of a clinical development program that evolved over time based on sound, basic scientific principles. Initial clinical data on the effects of mepolizumab on lung function in a general asthmatic population were disappointing. However, it became clear that mepolizumab may be more effective against other clinical endpoints, particularly asthma exacerbations, in patients with more severe disease. Furthermore, a developing understanding of asthma disease pathobiology led to the identification of an appropriate target population and predictive biomarker for mepolizumab t…
Influence of Antisynthetase Antibodies Specificities on Antisynthetase Syndrome Clinical Spectrum Time Course
2019
Antisynthetase syndrome (ASSD) is a rare clinical condition that is characterized by the occurrence of a classic clinical triad, encompassing myositis, arthritis, and interstitial lung disease (ILD), along with specific autoantibodies that are addressed to different aminoacyl tRNA synthetases (ARS). Until now, it has been unknown whether the presence of a different ARS might affect the clinical presentation, evolution, and outcome of ASSD. In this study, we retrospectively recorded the time of onset, characteristics, clustering of triad findings, and survival of 828 ASSD patients (593 anti-Jo1, 95 anti-PL7, 84 anti-PL12, 38 anti-EJ, and 18 anti-OJ), referring to AENEAS (American and Europea…
Activation of Astrocytes in the Persistence of Post-hypoxic Respiratory Augmentation
2021
Acute hypoxia increases ventilation. After cessation of hypoxia loading, ventilation decreases but remains above the pre-exposure baseline level for a time. However, the mechanism of this post-hypoxic persistent respiratory augmentation (PHRA), which is a short-term potentiation of breathing, has not been elucidated. We aimed to test the hypothesis that astrocytes are involved in PHRA. To this end, we investigated hypoxic ventilatory responses by whole-body plethysmography in unanesthetized adult mice. The animals breathed room air, hypoxic gas mixture (7% O2, 93% N2) for 2min, and again room air for 10min before and after i.p. administration of low (100mg/kg) and high (300mg/kg) doses of a…
Trends in pregnancy outcomes in patients with pulmonary hypertension: still a long way to go

Mild obstructive sleep apnoea (OSA) and arterial hypertension in the EuropeanSleep Apnoea Database (ESADA) cohort study.
2018
Background: Mild obstructive sleep apnoea (OSA) is highly prevalent, however its association with important clinical outcomes like arterial hypertension remains unknown. Aims and Objectives: To investigate the association between mild OSA and arterial hypertension in the European Sleep Apnoea Database (ESADA) cohort after adjusting for relevant confounding factors. Methods: A multicentric sample of 4974 adults from the ESADA cohort who showed simple snoring or mild OSA at cardiorespiratory polygraphy was studied. We compared the predictive value of mild OSA (AHI 5- Results: Arterial hypertension prevalence was 37% in mild OSA patients (n=2457) compared to 20% in non-apnoeic snorers (n=2517,…
Resumption of Ventilation at the End of Obstructive Sleep Apneas is not Determined by Diaphragmatic Fatigue
1988
In patients affected by obstructive sleep apnea syndrome (OSAS) a progressive increase of the force developed by the respiratory muscles is usually observed during the occlusive phase before upper airway patency is resumed (Onal and Lopata, 1986).
