Previous studies have suggested that systemic viral infections may increase risks of dementia. Whether this holds true for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus infections is unknown. Determining this is important for anticipating the potential future incidence of dementia.

Background: Although extracorporeal membrane oxygenation (ECMO) is an effective technique for life support, the incidence of acute kidney injury (AKI) during ECMO support remains high. Dexmedetomidine (DEX), which has been widely used for sedation during ECMO, possesses several properties that help reduce the occurrence of AKI. This study aimed to investigate the protective effect of DEX on kidney function during ECMO.

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: Patients presenting to the emergency department (ED) with chest pain often have abnormal high-sensitivity troponin (hsTn). However, only about 5% have an acute coronary syndrome. We aimed to assess the safety, feasibility and utility of a clinical disposition protocol including outpatient observation with stress cardiac-magnetic-resonance (CMR) in intermediate-risk patients with abnormal hsTn of unclear etiology.

Background: Ultrasound-assisted catheter-directed thrombolysis (USAT) is nowadays available as an alternative reperfusion approach for acute pulmonary embolism (PE). The lytic agent recombinant tissue-type plasminogen activator (rt-PA) activates the effector protease plasmin to induce fibrinolysis. The aim of this study was to identify predictive markers for the efficacy of USAT in patients with acute PE.
