The researchers said the results “suggest that YKL-40 has potential as a biomarker, with its…

Complication rates for elective surgeries in people with inherited bleeding disorders like hemophilia are low in Australia, reflecting good safety in their performance despite guidelines not always being followed, a study reported. Use of a specialty hemophilia treatment center (HTC) for surgery, and use of factor replacement therapy were among guidelines sometimes…

The teenage years are tough for most children but for those living with a chronic bleeding disorder, these years can be extra stressful. When they’re young, most of a hemophilia patient’s needs are met by their parents and they can be suitably supervised to ensure they come to no harm. However,…
