Priority actions for elevating liver health in Canada: A call to action
02/02/2023
Chronic liver disease and its complications impart tremendous patient and health system burdens that are largely preventable in Canada. In addition to crystallized efforts to eliminate viral hepatitis, prevention and early case-finding of patients at risk of ALD and NAFLD along with fibrosis detection offer opportunities to interrupt the disease process and extend survival. National policy and organizational support of care teams will be critical to the successful control of this silent epidemic in Canada.

Screening Patterns of Nonalcoholic Fatty Liver Disease in Children with Obesity in Canadian Primary Care: A Cross-Sectional Study
24/12/2022
In our study, we examined the proportion of childhood NAFLD screening in a large national multicenter database and identified very low screening rates (8.7% in the past year and 23.6% ever screened). Among the children with suspected NAFLD, many had associated comorbidities, including depression, hypertension, and dyslipidemia. As a result of its silent nature, it is likely that patients with NASH cirrhosis may develop the disease as youths and remain undiagnosed until they have reached adulthood [25], highlighting the importance of early detection and intervention. There is a critical need for PCPs and pediatric specialists to work together toward establishing a clinical referral pathway to address the identified gaps in screening and management of pediatric NAFLD in Canadian primary care.
