As the value of organs increases, people have a greater incentive to sell and trade.
Every extra organ available for donation is potentially lifesaving. And it can be done safely and ethically.
Biased algorithms in health care can lead to inaccurate diagnoses and delayed treatment. Deciding which variables to include to achieve fair health outcomes depends on how you approach fairness.
Liver transplant waitlists can range from 30 days to over five years. Developing treatments that spur liver regeneration could help reduce demand for scarce organs.
From next year, uterus transplants are being trialled in Australia. But it’s likely to be a while before they becomes mainstream clinical treatment.
China’s industrial-scale organ trafficking practice has been executing prisoners of conscience and using their organs for transplantation for decades. This is known as forced organ harvesting.
Patients with blood cancer undergoing stem cell transplantation have a high risk of complications. The bacteria in their gut, however, can help their immune system recover and fight infections.
The heart used in the first pig-human transplant was infected with a pig virus. This reveals that using other species as organ donors may not provide a solution for organ shortages.
Recent successes putting genetically modified pig organs into people have brought xenotransplantation back into the spotlight.
New developments in organ transplants from animals show promise. However, there has been no public engagement about a potential risk. It may streamline a pathway to humans for new zoonotic diseases.
David Bennett owes a debt of gratitude, not only to the surgeon’s who saved his life but to Peter Medawar, the person who discovered why organs are rejected.
People with weakened immune systems are at a high risk of severe and prolonged COVID-19 infections. An extra vaccine dose can bolster protection.
‘Chimera’ creatures with human organs could be medically useful – but can we really treat them like other animals?
Printing organs could reduce the need for human donor organs. And 3D printed organs using a patient’s own cells would increase successful organ transplants by reducing the risk of rejection.
Deemed consent organ donation means that everyone is assumed to be an organ donor unless they opt out, but assuming consent raises some ethical issues.
New strategy helps build synthetic organs from scratch. This enabled the researchers to grow functioning liver tissue in the lab that could be transplanted into mice with liver disease.
From expanding children’s coverage to reducing surprise bills, Biden and lawmakers may be able to broaden health care access.
As policymakers weigh financial aid for the airline industry, they have an opportunity to help make the US organ transplantation system more equitable at the same time.
Thousands of Canadians are on waiting lists for life-saving organ transplants. An opt-out organ donor system, like the one Nova Scotia is implementing, could reduce avoidable deaths and suffering.
