This fatty diet provided the necessary calories to develop bigger brains, contradicting the widely held view that meat consumption was crucial for human evolution.
A new Yale study found that adults tend to underestimate the pain experienced by girls, attributing this to culturally ingrained myths about boys being more stoic and girls being more emotive. The researchers hope their findings will lead to further investigation into biases in pain assessment and health care.
A recent study published in JAMA Internal Medicine found that prescribed opioids increase the risk of pneumonia in individuals with and without HIV. Patients taking medium or high doses of opioid painkillers were at greater risk for pneumonia, particularly those with immunosuppressive properties.
The opioid crisis roadmap neglects significant data on sex and gender differences, which are crucial for developing effective interventions. Women experience distinct pain and addiction patterns compared to men, and are more likely to relapse and face greater functional impairment.
