Sex Differences in Pulmonary Hypertension
Abstract
Pulmonary hypertension (PH) includes multiple diseases that share as common characteristic an elevated pulmonary artery pressure and right ventricular involvement. Sex differences are observed in practically all causes of PH. The most studied type is pulmonary arterial hypertension (PAH) which presents a gender bias regarding its prevalence, prognosis, and response to treatment. Although this disease is more frequent in women, once affected they present a better prognosis compared to men. Even if estrogens seem to be the key to understand these differences, animal models have shown contradictory results leading to the birth of the estrogen paradox. In this review we will summarize the evidence regarding sex differences in experimental animal models and, very specially, in patients suffering from PAH or PH from other etiologies.

- Links Fusarial mycotoxins and behaviour: possible implications for psychiatric disorder. • Schoental R. Man and animals are sporadically exposed to mycotoxins (the secondary metabolites of moulds), which include those produced in damp and cool environment by the almost ubiquitous soil-microfungi, the Fusaria. Perinatal exposure to the mycotoxins may cause damage to many organs, including the CNS and those which are targets for oestrogenic agents. Depending on the levels of the mycotoxins and the time of their action, the effects may manifest themselves as neonatal abnormalities, or as neurological and behavioural anomalies and chronic disorders later in life. The relationship between the anatomical and behavioural development of individuals and their perinatal exposure to fusarial mycotoxins requires further investigation · 4 shared tags
