Cardiopulmonary complications are infrequent in patients with ventriculoatrial shunts (VAS). We report the case of an 18-year-old man with congenital hydrocephalus who developed pulmonary arterial hypertension (PAH) in the long-term follow-up after a VAS procedure. He presented with progressive exertional dyspnea, stabbing chest pain and acral cyanosis. Echocardiography showed severe PAH and a digitiform mass adhered to the distal catheter. A ventilation/perfusion scan suggested chronic pulmonary embolisms. Anticoagulation with intravenous heparin was started and thrombus resolution was achieved, but PAH remained. It is necessary to bear in mind complications linked to VAS when treating a patient with this device.

Background: Currently, there is a deficiency in nomograms specifically designed for predicting the failure of high-flow nasal cannula (HFNC) oxygen therapy in patients with hypercapnic acute respiratory failure (hypercapnic ARF). The aim of this retrospective study is to develop and evaluate a nomogram that assesses the risk of HFNC failure in this patient population.
Methods: Patients with ARF and hypercapnia (PaCO ≥ 45 mmHg in the initial arterial blood gas) who received HFNC in the intensive care unit (ICU) from January 1, 2020 to December 31, 2023 were enrolled in this study.
EULAR recommendations for the treatment of systemic sclerosis: 2023 update.

Objectives: To update the 2017 European Alliance of Associations for Rheumatology (EULAR) recommendations for treatment of systemic sclerosis (SSc), incorporating new evidence and therapies.
Methods: An international task force was convened in line with EULAR standard operating procedures. A nominal group technique exercise was performed in two rounds to define questions underpinning a subsequent systematic literature review.

Atherosclerosis is one of the leading causes of ischemic cardiovascular disease worldwide. Recent studies indicated that vascular smooth muscle cells (VSMCs) play an indispensable role in the progression of atherosclerosis. Exosomes derived from mesenchymal stem cells (MSCs) have demonstrated promising clinical applications in the treatment of atherosclerosis.

This study investigated the sexual dimorphism in right ventricle (RV) remodeling in right heart failure susceptible Fischer CDF rats using the pulmonary artery banding (PAB) model. Echocardiography and hemodynamic measurements were performed in adult male and female Fischer CDF rats at 1- or 2-weeks post-PAB. RV systolic pressure and RV hypertrophy were significantly elevated in PAB rats compared to sham control at 1- and 2-weeks post-PAB; however, no differences were observed between male and female rats.

Hepatopulmonary syndrome (HPS) and portopulmonary hypertension (POPH) are two distinct pulmonary vascular complications seen in patients with liver disease and/or portal hypertension. HPS is characterized by disturbed gas exchange and hypoxemia because of intrapulmonary vascular dilatations. POPH is defined by pulmonary arterial hypertension, which might lead to right heart failure.
