Black and Asian patients here are forced to wait a year longer on average because of the low proportion of donors from similar backgrounds.
The number of Londoners turning to food banks increased by more than 120% between 2013 and 2014.
The father of a baby who died after getting an infection from a contaminated drip says he hopes his son's death will save other children.
It's been revealed more people in the capital have signed up to donate stem cells than anywhere else in the country.
The blood cancer charity Anthony Nolan has mapped its bone marrow register for the first time, showing the proportion of people in each region who are signed up to the bone marrow register.
The charity said that more than 80,000 people in the capital are now signed up to the register - 0.97% of London's population.
Speaking to ITV News, Yousef's father Raaid Hassan Sakkijha said the family had received excellent care from St Thomas's Hospital, but had become victims of an "unlucky incident".
The father of Yousef al-Kharboush, the 9-day-old poisoned at St Thomas Hospital in London, told an inquest hearing today:
"My son has just died. I don't want more children to. If you looked at Yousef, he was dying because of this product. He was suffering. He died because of this."
As 18 babies have been struck down with blood poisoning after contracting an infection from a suspected contaminated drip, here is what the intravenous fluid is thought to have been contaminated with:
- Bacillus cereus is a bacterium found in dust, soil and vegetation.
- It produces very hardy spores which in the right conditions can grow and create a toxin which causes illness.
- It is likely to be on most surfaces.
- These toxins can cause two types of illness: one type characterised by diarrhoea, and the other, by nausea and vomiting.
- The duration of the illness can last about a day.
- The symptoms can begin to show after six hours.
There is more to be done over patient safety, the Health Secretary has said, after a batch of a food supplement was "strongly linked" to the death of one baby and the illness of 17 others.
Speaking at the NHS Confederation's annual conference in Liverpool, Jeremy Hunt said: "The truth is that we have come a long way (in patient safety) but we have a lot further to go.
"Today's story about the tragic blood poisoning of 18 children shows we can never take safety for granted. It also shows the importance of prompt and early identification of problems".
Three more cases of blood poisoning linked to a batch of intravenous liquid given to babies have been identified by health officials.
Public Health England (PHE) said yesterday that a batch of a food supplement was "strongly linked" to the death of one baby and the illness of 14 others.
PHE officials have now identified three further cases of septicaemia in babies being treated in neonatal units in hospitals in England - bringing the total number of cases to 18.
One case was confirmed at Peterborough City Hospital in Cambridgeshire and two probable cases have been identified at Southend University Hospital and Basildon University Hospital, both in Essex, she said.
ITV News understands that up to 400 units of the ITH Pharma product are distributed to 30-40 hospitals every day.
The big question is: if health officials were so quick to identify a particular incident at the plant which potentially led to a contamination, why didn't the firm identify and deal with the incident itself?
The reassurance we can give is that any potentially-contaminated product should have expired on Monday and so should not be on any hospital shelf now.
