Evaluation of the efficacy and safety of gravitational therapy in a cohort of patients with systemic sclerosis.

Background: The exposure to artificial gravity (AG) through human centrifugation is the basis of the treatment called gravity therapy (GT), in which the mechanical stimulation over the vessel wall, induces the synthesis and release of prostacyclin. It has been used for more than four decades in Uruguay in the treatment of different vascular-based pathologies. In patients with systemic sclerosis (SSc) it has shown good benefits and excellent safety profile over the years.

The application of artificial gravity in medicine and space.

Gravity plays a crucial role in physiology. The lack of gravity, like in long duration spaceflight missions, cause pathologies in , the musculoskeletal system, cardiovascular deconditioning, immune system deprivation or brain abnormalities, to just mention a few. The application of artificial gravity through short-arm human centrifugation (SAHC) has been studied as a possible countermeasure to treat spaceflight deconditioning.

Impact of COVID-19 outbreak on ischemic stroke admissions and in-hospital mortality in North-West Spain.

Background And Purpose: Spain has been one of the countries heavily stricken by COVID-19. But this epidemic has not affected all regions equally. We analyzed the impact of the COVID-19 pandemic on hospital stroke admissions and in-hospital mortality in tertiary referral hospitals from North-West Spain.
