Sound-based cough peak flow estimation in patients with neuromuscular disorders.

Introduction/aims: Cough impairment is common in individuals with neuromuscular disorders and is associated with respiratory infections and shorter survival. Cough strength is assessed by measuring cough peak flow (CPF) using a flow meter, but this method requires a complex device setup and trained staff. The aim of the study is to evaluate the reliability of a smartphone app to estimate CPF based on cough sounds in a cohort of individuals with neuromuscular disorders.

Ultrasonographic and manometric study of the tongue as biomarkers of dysphagia in patients with amyotrophic lateral sclerosis.

Background: The possibility of having methods to assess dysphagia in amyotrophic lateral sclerosis (ALS) patients in a minimally invasive manner could facilitate follow-up and allow performing of therapeutic interventions at earlier stages of the disease. The aim of the study was to analyze the role of tongue strength and thickness in ALS patients and their correlation with dysphagia and bulbar function.

Methods: A sample of outpatients with ALS was evaluated for demographic and clinical features.

Higher mortality and intubation rate in COVID-19 patients treated with noninvasive ventilation compared with high-flow oxygen or CPAP.

The effectiveness of noninvasive respiratory support in severe COVID-19 patients is still controversial. We aimed to compare the outcome of patients with COVID-19 pneumonia and hypoxemic respiratory failure treated with high-flow oxygen administered via nasal cannula (HFNC), continuous positive airway pressure (CPAP) or noninvasive ventilation (NIV), initiated outside the intensive care unit (ICU) in 10 university hospitals in Catalonia, Spain. We recruited 367 consecutive patients aged ≥ 18 years who were treated with HFNC (155, 42.

Respiratory and Peripheral Muscle Weakness and Body Composition Abnormalities in Non-Cystic Fibrosis Bronchiectasis Patients: Gender Differences.

As demonstrated in COPD, bronchiectasis patients may experience respiratory and peripheral muscle dysfunction. We hypothesized that respiratory and peripheral (upper and lower limbs) muscle function and nutritional status may be more significantly altered in female than in males for identical age and disease severity. In mild-to-moderate bronchiectasis patients ( = 150, 114 females) and 37 controls ( = 37, 21 females), radiological extension, maximal inspiratory and expiratory pressures (MIP and MEP), sniff nasal inspiratory pressure (SNIP), hand grip and quadriceps muscle strengths, body composition, and blood analytical biomarkers were explored.

[Respiratory physiotherapy in post-COVID-19: a decision-making algorithm for clinical practice].

The outbreak of COVID-19 has posed a great challenge for the healthcare system which has been later aggravated by the need of managing clinical manifestations and potential sequelae in COVID-19 survivors. In this context, respiratory Physiotherapy emerges as a cornerstone in the interdisciplinary management warranted in this population. Given that the implementation and resources available for the interdisciplinary therapeutic interventions in Spain is scarce, it is essential to perform a comprehensive, exhaustive and personalised assessment.

Airway Clearance and Mucoactive Therapies.

The respiratory system is constantly exposed to external pathogens but has different and effective defense systems. The pathophysiology of bronchiectasis affects the defense system considerably in that alterations occur in the airway that reduce its effectiveness in mucociliary clearance and the greater presence of mucins leads to the accumulation of more adherent and viscous mucus. One of the pillars of treatment of this disease should be improvement of mucociliary clearance and a decrease in the adherence and viscosity of the mucus.

[Could Inspiratory Muscle Function Be an Equivalent of Lung Hyperinflation in COPD Patients?].

Introduction: Chronic obstructive pulmonary disease (COPD) is the respiratory disease that causes the greatest morbidity and mortality worldwide. Lung function parameters and systemic manifestations have been defined as prognostic factors; however, they have limitations. The aim of this study was to analyze whether inspiratory muscle strength could reflect lung hyperinflation, and therefore serve as a prognostic factor in COPD patients.
