Primary endpoint

Introduction Airway pressure in the first 100ms of an occluded inspiration (P0.1) evaluates the respiratory center activity, increasing in the presence of respiratory muscle weakness. It is uncertain if its activity can compensate for respiratory muscles weakness in amyotrophic lateral sclerosis (ALS). Methods: Consecutive ALS patients with P0.1 evaluated at first visit were included. Depending on

Introduction Amyotrophic lateral sclerosis (ALS) has a reported incidence of 1–2/100,000 person-years. It is estimated that there are 5000 people with ALS in the UK at any one time; however, the true figure and geographical distribution, are unknown. In this study, we describe the establishment of a population register for England, Wales, and Northern Ireland and report-estimated incidence. Methods:

Interleukin-6 (IL6) expression increases in atrophying muscles and lung tissue during compromised function. Considering ALS patients undergo these same pathological changes, IL6 levels may be relevant for prognostication and treatment. The amount of soluble IL6 receptor, dictated by the IL6R358Ala variant, and local tissue environment in which IL6 signaling occurs is known to influence the ultimate

We describe the telemedicine experience of an Italian ALS tertiary Center during COVID-19 pandemic. A total of 144 visits were scheduled between 6th March and 6th April 2020.
