Barbara Natterson-Horowitz, Professor of Medicine in the Division of Cardiology at UCLA Medical School, offered an unusual perspective on how human patients, including those suffering from mental illnesses, can be helped by applying insights from animal health. We caught up with Barbara to learn more about how her Zoobiquity idea improves understanding of ourselves and the natural world.
What motivated you to speak at TEDMED?
After 20 years of practicing cardiology taking care of patients with heart attacks and high cholesterol, I was thrust into the world of veterinary medicine. Seeing my human patients as human-animal patients completely changed how I practice medicine and understand health and disease. Insights from this species-spanning approach to medicine can benefit human and animal practitioners and patients alike. It’s thrilling to introduce this approach to physicians, psychologists, dentists, nurses, etc. and watch their viewpoints transform; the exposure at TEDMED led to a collaboration between a celebrated human breast cancer physician studying a mutation that causes breast cancer in women with a veterinary oncologist working on the same mutation that causes breast cancer in jaguars and other animals!
Why does this talk matter now?
Animals and humans get basically the same diseases. From heart failure, diabetes and brain tumors to anxiety disorders and compulsions, the challenges we face aren’t uniquely human. Discovering why, where, and how non-human animals get sick reveals crucial but hidden clues to human health and illness. For instance:
Breast cancer: When beluga whales began dying of breast and colon cancer in the St. Lawrence estuary, a parallel epidemic of breast cancers in women was discovered in the same region. This species-spanning breast cancer outbreak was ultimately linked to toxins from local aluminum smelting plants.
Obesity: Medical insights into obesity — which challenges physicians and veterinarians alike as animal and human patients are becoming more fat — are generated by a zoobiquitous approach. Awareness of worsening obesity in domestic and wild animal populations challenges us to consider environmental factors including endocrine disrupting chemicals, antibiotics, and even climate change as contributors to the “plurality of obesity epidemics.”
Infectious disease: The majority of infections that could create human pandemics come from animal communities. From Ebola to West Nile Virus, SARS to H1N1, some of most worrisome threats to human health and survival are encountered first by veterinarians and animal experts. If we fail to pay attention to these experts and miss out on the opportunity to collaborate, we lose crucial information and increase unnecessary risk for human populations.
How do you see your work fitting into species-survival, wildlife preservation and conservation?
Zoobiquity emphasizes the interconnectedness of animal and human lives and ecosystems. Animals can be sentinels of disease in humans. When horses in Venezuela start to die, it can mean equine encephalitis may threaten local human populations. When cormorants and crows get sick with West Nile virus in Queens and the Bronx, elderly and immunocompromised patients may also be at risk for the virus. On the other hand, humans can be sentinels of disease in animals. Human outbreaks of Brucellosis often lead to identification of sick and suffering animals. The detection of lead poisoning in a child often leads to exposure and disease in local wildlife. Bringing practitioners of animal and human health together encourages the transfer of information from the world of human medicine that is vitally relevant and important to wild animal populations.
What do you hope for the legacy of Zoobiquity?
Zoobiquity Conferences have now been held across the US and internationally. At these events human health practitioners including physicians, nurses, dentists, psychologists and others come together with animal health practitioners including veterinarians, behaviorists, nutritionists and others to discuss the shared diseases of their different species. I’ve heard some veterinarians joke, “real doctors take care of many species.” Bringing the comparative approach to the human medical community has the power to transform how physicians, nurses, psychotherapists and others understand disease, their patients and the environmental and evolutionary factors that link us all together. I hope Zoobiquity is successful in bridging the worlds of animal and human health, ecology and evolutionary biology.
