PainRelief.com: What is the background for this study?

Response: It is estimated that chronic pain can affect up to 20% of children undergoing surgery.  We know that alterations in sensory input during critical periods of development can have lasting effects on normal sensory processing later in life.  The developing peripheral nervous system undergoes substantial changes in function during the neonatal period as it receives information from the external environment.  Injuries, including surgery, that occur during this early developmental window can change the way a patient responds to re-injury in adolescence and young adulthood, a phenomenon called neonatal nociceptive priming. 

         At the same neonatal time, the immune system is also developing and responding to changes in the body.  Surgery is known to cause an immune response that is normally activated to facilitate wound healing and regulate acute pain so that the tissues can undergo proper repair after damage.  However, it was not clear how early life surgery could affect the developing immune system to influence pain responses later in life. 

         Since we knew that one particular type of immune cell, the macrophage (which regulates inflammation and tissue repair in addition to acute pain), can play a role in long term responses to surgery, we investigated how this cell type may play a role in the transition from acute post-surgical pain in neonates to prolonged responses to reinjury later in adolescence.

PainRelief.com: What are the main findings of the study?

Response: We examined 10 movies and the first seasons of 6 TV Netflix shows based on popularity among adolescents.  

Across the 616 scenes showing painful events, the majority showed violence and injuries and not the kinds of pain kids experience in real life (e.g., medical procedures, chronic pain. Characters from marginalized (gender diverse, girls) and minoritized groups (individuals with racialized identities) were underrepresented.

Overall, there was an overwhelming LACK of empathy shown to characters observing others in pain. The media perpetuated gender and racialized stereotypes.
