A Comparative Study of Ultrasonography and CT Venography in the Diagnosis of Budd‐Chiari Syndrome

Journal of Clinical Ultrasound, EarlyView.
Budd‐Chiari syndrome (BCS) is characterized by hepatic venous outflow obstruction from the hepatic veins to the junction of the inferior vena cava (IVC) and right atrium. Ultrasound (US) and CT venography (CTV) are used as imaging techniques for the diagnosis of BCS, and We compared the diagnostic efficacy of the two modalities. The results showed that

Pre‐operative transcranial Doppler ultrasound assessment of cerebral collateral circulation in children undergoing veno‐arterial extracorporeal membrane oxygenation or cardiac surgery

Journal of Medical Radiation Sciences, EarlyView.
A pre‐cannulation survey of the circle of Willis (CoW) using transcranial Doppler (TCD) ultrasound was implemented to assess cerebral collateral circulation in children undergoing VA ECMO or cardiac surgery with cervical cannulation. The technique, in use since 2019, employs high‐end ultrasound platforms to assess brain morphology, haemorrhage and ...

Peri‐implant hypoxia as a potential barrier against ferroptotic mechanisms during peri‐implant diseases: A cross‐sectional study

Journal of Periodontology, EarlyView.
Abstract Background Hypoxia modulates inflammation and oxidative stress through hypoxia‐inducible factor‐1α (HIF‐1α). Ferroptosis, an iron‐dependent cell death process, is regulated by glutathione peroxidase‐4 (GPX4) and involves lipid peroxidation markers like malondialdehyde (MDA).

Robotic arm‐assisted total knee arthroplasty reduces postoperative inflammatory response and blood loss compared to manual total knee arthroplasty: A matched‐pairs analysis of 688 patients

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Robotic arm‐assisted total knee arthroplasty (raTKA) has demonstrated several advantages over manual TKA (mTKA), including enhanced early recovery. Reduced soft tissue trauma and avoidance of femoral intramedullary canal opening have been hypothesised to lower the systemic inflammatory response.
