Balloon pulmonary angioplasty in patients with chronic thromboembolic pulmonary hypertension: short- and long-term results from a cohort in Brazil.
J Bras Pneumol
January 2025
Objective: A significant number of patients with chronic thromboembolic pulmonary hypertension (CTEPH) are not eligible for pulmonary endarterectomy and may be treated with balloon pulmonary angioplasty (BPA). Although BPA programs have recently been developed in Brazil, no results have yet been published. The objective of this study was to assess the clinical and hemodynamic progression of the first patients treated with BPA at our center.

These complications, potentially related to dose, young age, and concomitant high doses of adrenocorticotropic hormone and/or prednisolone, can lead to neurological symptoms. Upon withdrawal or dose reduction, symptoms and imaging changes tend to resolve.

Methods: This retrospective single-center analysis included all adults with ATAAD from 2011 to 2023. Patients were stratified into RF and no RF groups.
Article Synopsis
- Post-consumer waste management is currently ineffective, prompting the need for innovative methods like chemical recycling to handle materials such as PET and WCO.
- The study explored how co-pyrolysis of different ratios of PET and WCO could enhance energy efficiency and liquid product yields, significantly reducing the activation energy required for thermal degradation.
- Results indicated that this process not only increases the yield of valuable compounds like terephthalic acid but also suggests an effective approach for managing waste while producing chemical inputs.
Article Synopsis
- Paropsisterna bimaculata is a harmful pest for eucalyptus trees, leading to significant defoliation and even tree death in Tasmanian plantations, impacting wood production.
- The study focused on creating an ecoclimatic index model using CLIMEX software to predict where this pest might spread globally, identifying high-risk areas for eucalyptus crops.
- Results indicated that regions with temperate climates across Asia, Africa, Europe, Oceania, and America are especially vulnerable, with a notable risk present in Brazil's southern and southeastern areas, guiding prevention strategies.
