Abstract

fetched live from OpenAlex

Past decades have witnessed an increasing interest in the field of pulmonary arterial hypertension (PAH). The large number of publications related to PAH reflects this interest. As a result, in contrast to 15 yrs ago, there are now at least seven different drugs as specific therapy targeting the pulmonary circulation that are approved for use in the USA and European Union, with some of them also approved for use in Canada, Japan, Australia and in some countries in Latin America. These medications have proved to increase exercise capacity [1–5], haemodynamics [2, 3, 6], quality of life [7–9] and even survival [5]. Nevertheless, there is still room for further improvements, since the mortality rate remains significantly high [10, 11]. Haemodynamically, PAH is characterised by progressive increase in pulmonary vascular resistance, as a consequence of vascular remodelling within the pre-capillary territory, leading to right ventricular failure and, eventually, death [12]; numerically, this is translated to the presence of a mean pulmonary artery pressure >25 mmHg, with normal pulmonary artery occlusion pressure (<15 mmHg) [13]. This definition, although extremely important for the proper characterisation of a pre-capillary impairment, might be misleading when focusing on specific patients or, more properly, specific forms of PAH. The most recent published nomenclature for pulmonary hypertension date from 2003 [13], and despite the fact that it has been recently revised (at the International Symposium of Pulmonary Hypertension, held in Dana Point, CA, USA, in the first quarter of 2008) it still includes in group 1 (PAH) several diseases that share the haemodynamic profile of pre-capillary pulmonary hypertension but present a completely distinct clinical course, such as idiopathic PAH, scleroderma-associated PAH and portopulmonary hypertension [10, 14, …

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
