Pulmonary hypertension is a rare disease that affects lung arteries causing their progressive narrowing. Diagnosis generally occurs late, when treatment options are less, because there are not any diagnostic tools for early detection. On the occasion of the World Pulmonary Hypertension Day on May 5th, the Fundación Contra la Hipertensión Pulmonar (FCHP), a foundation against pulmonary hypertension, has launched a crowd funding platform to sponsor a research project called Enpathy; its main objectives are to facilitate early diagnoses and to find a definitive cure. The project involves scientists from several Spanish hospitals and universities, the Universidad de Valladolid, for instance.

A research team at the Ibiomed (an institute of biomedicine at the Universidad de León, Spain) has collaborated in an article recently published in Gaceta Sanitaria, a journal edited by the Sespas (a Spanish body of public healthcare and health management); the article analyzes levels of nitrate and other elements in bottled and municipal water in Spain. The study concludes that the amount of nitrate in municipal water does not exceed legal levels but differs depending on regions; and trace elements such as arsenic, nickel and cadmium are present in such small amounts that are unquantifiable in almost all samples, for both running water and bottled water.
