Cetaceans are highly adapted marine mammals whose survival depends on precise auditory and echolocation systems. Therefore, disease processes affecting these systems, including parasitic infections pose significant morbidity and may result in stranding and death. Here, we describe the pathologic and parasitological findings in an adult, male melon-headed whale ( Peponocephala electra ) stranded dead on the Brazilian coast. The...

Pulmonary arterial hypertension (PAH) is a progressive disease characterised by systemic oxidative stress and inflammation that extends beyond the pulmonary vasculature to the musculoskeletal system. Combined exercise training (ET), incorporating aerobic and resistance components, is a promising non-pharmacological intervention, but its effects on musculoskeletal oxidative stress and inflammation remain unclear. To evaluate th...

The six-minute walk test (6MWT) is a common method to assess submaximal exercise capacity in children and adults with pulmonary arterial hypertension (PAH) and other chronic diseases. There is no guideline specifically for 6MWT in children. In this observational pilot study, we evaluated the impact of procedural variations on the outcome of the 6MWT in the real-world clinical setting at pediatric PAH programs. We collected 6MW...
