Severe pulmonary arterial hypertension and cardiogenic shock in acute systemic lupus erythematosus.
BMJ Case Rep
January 2025
Department of Allergy, Immunology and Respiratory Medicine, Alfred Hospital, Melbourne, Victoria, Australia.
We describe a woman in her late 20s with newly diagnosed systemic lupus erythematosus (SLE), who presented with fulminant pulmonary arterial hypertension (PAH) requiring inotropic and extracorporeal support. She was established on triple pulmonary vasodilator therapy with concurrent aggressive immunosuppression; however, treatment was complicated by infection and diffuse alveolar haemorrhage, necessitating delays in immunosuppression and withdrawal of epoprostenol. Despite this, with ongoing suppression of her SLE, her pulmonary haemodynamics improved, with normal pressures on right heart catheterisation several months later allowing stepdown to sildenafil monotherapy.

Background: Viremia has been detected in a significant proportion of patients with acute respiratory viral infection, yet its clinical value remains underappreciated.
Objectives: This study synthesized available evidence to comprehensively assess the prevalence of viremia and its impact on clinical outcomes.
Data Sources: Data were retrieved from Medline (via Ovid), Embase, and the WHO COVID-19 database.
Radiation exposure in neurosurgical intensive care unit patients: Balancing diagnostic benefits and long-term risks.
Life Sci
January 2025
Department of Neurosurgery, Philipps University of Marburg, Baldingerstraße, 35033 Marburg, Germany; Center for Mind, Brain and Behavior (CMBB), 35043 Marburg, Germany.
Background: X-ray, computed tomography (CT), and digital subtraction angiography (DSA) techniques are indispensable in managing critically ill neurosurgical patients. However, repeated diagnostic imaging leads to cumulative radiation exposure, raising concerns about long-term risks such as malignancies. This study evaluates the frequency, dosage, and implications of radiation exposure in a neurosurgical intensive care unit (NICU) patient cohort.

Pulmonology
December 2025
Department of Emergency and Intensive Care, Fondazione IRCCS San Gerardo dei tintori, Monza, Italy.
Background: Non-invasive helmet respiratory support is suitable for several clinical conditions. Continuous-flow helmet CPAP systems equipped with HEPA filters have become popular during the recent Coronavirus pandemic. However, HEPA filters generate an overpressure above the set PEEP.

December 2025
Alma Mater Studiorum, Department of Medical and Surgical Sciences (DIMEC), University of Bologna, Bologna, Italy.
Nasal high flow (NHF) therapy is an established form of non invasive respiratory support used in acute and chronic care. Recently, a new high flow nasal cannula with asymmetric prongs was approved for clinical use. The clinical benefits of the new cannula have not yet been defined and no evidence are available on the use of asymmetric NHF support in patient with Chronic Obstructive Pulmonary Disease (COPD).
