The INCREASE trial evaluated inhaled treprostinil in patients with pulmonary hypertension associated with interstitial lung disease. The randomized, placebo-controlled study demonstrated an improvement in exercise capacity measured by the six-minute walk distance and reduced the risk of clinical worsening compared with placebo. The findings are important because pulmonary hypertension in ILD can add a major burden of symptoms and functional limitation, yet treatment options historically have been limited. The study supports the idea that pulmonary vascular disease should be actively considered when symptoms or functional decline appear disproportionate to the underlying parenchymal lung disease. This is closely aligned with the NAPCON session on screening for pulmonary hypertension in progressive ILD. For HCPs, the message is to recognize when pulmonary vascular evaluation may add diagnostic and therapeutic value rather than assuming every decline is caused by worsening fibrosis alone. The treatment studied here is specific to pulmonary hypertension associated with ILD and should not be generalized to all forms of pulmonary hypertension. The paper is especially useful for multidisciplinary care involving ILD specialists, pulmonary hypertension teams and rehabilitation services.

Recent research defines ferro-aging as a conserved iron-lipid axis driving organ decline across primates. Age-related iron dyshomeostasis stimulates ACSL4-mediated lipid peroxidation, promoting cellular senescence. Notably, vitamin C directly inhibits ACSL4, suppressing phospholipid oxidation and multi-organ decay.
