Dr. Pui studies health behaviors and medical treatments related to children's health. He works on programs that teach health and safety to children, especially those from minority backgrounds and special needs. One of his notable projects, called SEED, has led to significant improvements in the quality of life and emotional well-being for participants. Additionally, he investigates the risks associated with child neglect and online exploitation, emphasizing the urgent need to protect vulnerable children. His work also extends to innovative treatments for serious health conditions like non-Hodgkin lymphoma and knee replacement surgeries.
Key findings
After the SEED program, 526 children reported significant improvements in quality of life, emotional regulation, and resilience, with benefits lasting for at least six months.
Neglected children are 11 times more likely to experience contact childhood sexual abuse and 3.5 times more likely to engage in risky online behaviors.
41% of patients using a new knee implant design were able to bend their knees more than 130 degrees compared to only 19% with the older design.
Out of 22 children with recurrent non-Hodgkin lymphoma treated with intensive chemotherapy, 10 achieved lasting health improvements.

Plain English This study examined the link between child neglect and childhood sexual abuse (CSA) in Hong Kong, focusing on how online behaviors may contribute to this issue. It found that neglected children are 11 times more likely to experience contact CSA and 3.5 times more likely to engage in risky online behaviors. These risky behaviors can lead to further online exploitation, which increases the chances of experiencing offline abuse. Addressing child neglect is crucial to preventing CSA.
Who this helps: This helps children at risk of abuse and the professionals working to protect them.

Plain English This study looked at a new design for knee replacement implants to see if it could help patients move their knees better and feel less pain after surgery. Researchers found that 41% of patients with the new implant could bend their knees more than 130 degrees, compared to just 19% of those with the older design. Additionally, there were fewer complications with the new design, such as the need for more surgeries or manipulations.
Who this helps: This benefits knee replacement patients by potentially improving their recovery and mobility.

Plain English This study looked at how intensive chemotherapy combined with stem-cell support can help children with hard-to-treat non-Hodgkin lymphoma (NHL). Out of 22 children treated, 10 of the 19 who had a positive response to earlier chemotherapy became healthy and stayed that way, while 9 children died from their disease or complications after treatment. This research matters because it shows that high-intensity treatments can significantly improve outcomes for children with certain types of recurrent NHL, making it a promising option for those with responsive disease.
Who this helps: This benefits children with recurrent non-Hodgkin lymphoma and their families.
