Association between History of Pregnancy and Liver Fibrosis Using Fibrosis-4 Index in Korean Postmenopausal Women: A Nationwide Population-Based Study.

Background: The association between a history of pregnancy and liver fibrosis remains unclear. Herein, we investigated the association between reproductive factors, including a history of pregnancy and liver fibrosis, in postmenopausal Korean women.

Methods: This study used nationally representative, population-based data collected from the Korea National Health and Nutrition Examination Survey 2008-2017.

Effectiveness of Retrobulbar Hyaluronidase Injection in an Iatrogenic Blindness Rabbit Model Using Hyaluronic Acid Filler Injection.

Background: Blindness caused by soft-tissue filler injection is the most tragic complication, with no standard treatments until recently. Retrobulbar hyaluronidase injection has been proposed as the treatment, but its effectiveness in visual compromise remains to be determined. The authors aimed to determine the effectiveness of retrobulbar hyaluronidase using soft-tissue filler in an iatrogenic blindness animal model.

Hyperdilution of CaHA fillers for the improvement of age and hereditary volume deficits in East Asian patients.

With their high elasticity and viscosity, calcium hydroxylapatite (CaHA) fillers are now widely used to treat age-related or hereditary facial soft tissue volume deficits. CaHA filler volume augmentation is further enhanced by its ability to stimulate neocollagenesis and improve skin quality. However, its high viscosity and cohesivity may hinder its spread and distribution, while its injection by cannula or needle may require moderate extrusion force and lead to uneven distribution or focal accumulation in tissues.
