HIV pre-exposure prophylaxis (PrEP) is an effective HIV prevention tool, reducing infection risk by up to 99% when used as prescribed. Despite its proven efficacy, PrEP uptake remains suboptimal, particularly among high-risk populations in Canada. Barriers to access and uptake, including stigma, financial constraints and healthcare accessibility, persist, highlighting the need for targeted interventions. The objective of this scoping review is to identify and map the extent and types of interventions, programmes, practices and policies aimed at increasing the acceptance, access, uptake and sustained use of HIV PrEP in Canada.
This review will use the Joanna Briggs Institute (JBI) Scoping Review methodology. Databases to be searched are MEDLINE, Embase, PsycINFO, Cochrane Library, CINAHL, Scopus and Web of Science from 2016 onwards. Two independent reviewers will screen studies, based on the inclusion criteria. The search results will be presented in a Preferred Reporting Items for Systematic Reviews and Meta-Analyses flow diagram. Data will be extracted from relevant studies by two independent reviewers and summarised to inform future research and policy development. This review will include studies focusing on individuals in Canada who are eligible for or using PrEP for HIV prevention. The interventions considered will address the awareness, acceptance, access, uptake and sustained use of PrEP. Studies must be set within the Canadian context, considering geographic, cultural and systemic factors. Exclusions include studies conducted outside Canada or those not addressing HIV prevention interventions.
This research will rely exclusively on previously published data and will not include human participants. Therefore, ethics approval is not required. For further clarification, please contact Stephen Hwang, Director, MAP Centre for Urban Health Solutions, Unity Health Toronto, at

Neonatal haemochromatosis, considered to be a gestational alloimmune liver disease (NH-GALD), is a rare but serious disease that results in fulminant hepatic failure. The recurrence rate of NH-GALD in a subsequent infant of a mother with an affected infant is 70%–90%. Recently, antenatal maternal high-dose intravenous immunoglobulin (IVIG) therapy has been reported as being effective for preventing recurrence of NH-GALD in a subsequent infant. However, no clinical trial has been conducted to date.
This is a multicentre open-label, single-arm study of antenatal maternal high-dose IVIG therapy in pregnant women with a history of documented NH in a previous offspring. The objective of this study is to evaluate the efficacy and safety of antenatal maternal high-dose IVIG therapy in preventing or reducing the severity of alloimmune injury to the fetal liver.
The clinical trial is being performed in accordance with the Declaration of Helsinki. The trial protocol was approved by the Clinical Research Review Board at four hospitals. Before enrolment, written informed consent would be obtained from eligible pregnant women. The results are expected to be published in a scientific journal.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a heterogeneous disease caused by multiple etiologies. It is characterized by excessive fat accumulation in the liver. Without intervention, MASLD can progress from steatosis to metabolic dysfunction-associated steatohepatitis (MASH), fibrosis and even to cirrhosis and hepatocellular carcinoma. However, the pathogenesis of MASH and the mechanism underlying the development of fibrosis remain poorly understood, posing challenges for accurate diagnosis of MASH and fibrosis. In this study, we analyzed tissue RNA-seq data and clinical information of healthy individuals and MASLD patients from multiple datasets, the key genes and pathways involved in the occurrence and progression of MASLD, MASH, and fibrosis were screened respectively. Our findings reveal that the development of MASLD, MASH and fibrosis is associated with lipid metabolism processes. Based on the RNA expression profiles of identified hub genes, we established three alternative diagnostic models for MASLD, MASH, and fibrosis. These models demonstrated excellent performance in the diagnosis of MASLD, MASH, and fibrosis, with AUC values exceeding 0.9, implicating its potential clinical values in disease diagnosis.
