Initial therapy in patients with pulmonary arterial hypertension and cardiovascular comorbidities.

Background: European guidelines recommend initial monotherapy in PAH patients with cardiovascular (CV) comorbidities based on the limited of evidence for combination therapy in this growing population.

Methods: A retrospective analysis was conducted on incident PAH patients enrolled in the French Pulmonary Hypertension Registry between 2009 and 2020. Propensity score matching was used to investigate initial dual oral combination therapy oral monotherapy in patients with at least one CV comorbidity (, hypertension, obesity, diabetes and coronary artery disease).

BTN2A1 targeting reprograms M2-like macrophages and TAMs via SYK and MAPK signaling.

Tumor-associated macrophages (TAMs), often adopting an immunosuppressive M2-like phenotype, correlate with unfavorable cancer outcomes. Our investigation unveiled elevated expression of the butyrophilin (BTN)2A1 in M2-like TAMs across diverse cancer types. We developed anti-BTN2A1 monoclonal antibodies (mAbs), and notably, one clone demonstrated a robust inhibitory effect on M2-like macrophage differentiation, inducing a shift toward an M1-like phenotype both in vitro and ex vivo in TAMs from patients with cancer.

Targeting the Hippo pathway to prevent radioresistance brain metastases from the lung (Review).

The prognosis for patients with non‑small cell lung cancer (NSCLC), a cancer type which represents 85% of all lung cancers, is poor with a 5‑year survival rate of 19%, mainly because NSCLC is diagnosed at an advanced and metastatic stage. Despite recent therapeutic advancements, ~50% of patients with NSCLC will develop brain metastases (BMs). Either surgical BM treatment alone for symptomatic patients and patients with single cerebral metastases, or in combination with stereotactic radiotherapy (RT) for patients who are not suitable for surgery or presenting with fewer than four cerebral lesions with a diameter range of 5‑30 mm, or whole‑brain RT for numerous or large BMs can be administered.

Pulmonary Artery Embolization in the Management of Hemoptysis Related to Lung Tumors.

(1) Background: Bronchial artery embolization has been shown to be effective in the management of neoplastic hemoptysis. However, knowledge of pulmonary artery embolization is lacking. The aim of this study was to evaluate the safety and efficacy of pulmonary artery embolization in patients presenting with hemoptysis related to lung tumors.
