AI Article Synopsis
- The study examined lung biopsy and autopsy specimens from 20 cases that could cause pulmonary hypertension, using the Edward and Heath classification system.
- Medial hypertrophy, which is thickening of the muscle layer in blood vessels, was identified as the most common and earliest change across all cases, regardless of the underlying cause of the condition.
- Additionally, the research observed specific changes related to different types of blood vessel diseases (arteriopathies/vasculopathies) present in the samples.
Article Abstract
The pulmonary vasculature was studied in lung biopsy/autopsy specimens of 20 cases, in conditions likely to lead to pulmonary hypertension. The changes were classified as per Edward and Heath classification and morphometric measurements to gauge medial and intimai hypertrophy were done. Medial hypertrophy was found to be the earliest and commonest change in all cases, irrespective of the pathogenic mechanism of pulmonary hypertension. Variable changes specific to various arteriopathies/vasculopathies were noted.

Monocytes and interstitial macrophages contribute to hypoxic pulmonary hypertension.
J Clin Invest

Department of Medicine, University of California San Francisco, San Francisco, United States of America.
Hypoxia is a major cause of pulmonary hypertension (PH) worldwide, and it is likely that interstitial pulmonary macrophages contribute to this vascular pathology. We observed in hypoxia-exposed mice an increase in resident interstitial macrophages, which expanded through proliferation and expressed the monocyte recruitment ligand CCL2. We also observed an increase in CCR2+ macrophages through recruitment, which express the protein thrombospondin-1 that functionally activates TGF-beta to cause vascular disease.

Background And Objective: PARP inhibitor (PARPi) treatment is an effective option for patients with metastatic castration-resistant prostate cancer (mCRPC). There are few data on the cardiovascular and thromboembolic safety of these agents in mCRPC, as cardiovascular and thromboembolic adverse events (AEs) are uncommon. Our aim was to analyze the incidence and risk of major adverse cardiovascular events (MACEs), thromboembolic events, and hypertension with PARPi therapy in mCRPC.

Mid-trimester preterm premature rupture of membranes is a rare complication of pregnancy associated with significant maternal and fetal risks. The ensuing prolonged oligohydramnios can lead to fetal pulmonary hypoplasia. In addition, there is an increased risk of miscarriage, preterm birth, and chorioamnionitis, contributing to septic morbidity in the mother-baby dyad.

The inflammatory response of lung tissue and abnormal proliferation of pulmonary artery smooth muscle cells are involved in the pathogenesis of high-altitude pulmonary hypertension (HAPH). Halofuginone (HF), an active ingredient derivative of Chang Shan (Dichroa febrifuga Lour. [Hydrangeaceae]), has antiproliferative, antihypertrophic, antifibrotic, and other effects, but its protective effects on HAPH remains unclear.
