Decriminalisation of abortion in the UK
On
Tuesday 23 October, yet another Ten-Minute Rule Bill on
this topic was debated at Westminster, this time in the
name of Diana Johnson MP. Though her Bill appeared
to be about bringing abortion access to Northern
Ireland, in reality it would remove most of the legal
safeguards around current abortion practice in Wales,
Northern Ireland and England. This is a step too
far. Such a radical proposal has no place in the
UK. While Ten-Minute Rule Bills are unlikely to
become law, they can, especially if they go to a vote,
have an important symbolic significance. And so it
came to pass that at 12.39 on Monday 23 October 2018,
Diana Johnson MP spoke. Then Fiona Bruce MP
responded. Then at 12.59 the House voted – the
Ayes, 208 and the Noes 123. Oh no! How could
that be? The Second reading of this Abortion Bill
will take place on Friday 23 November. [update: As expected, a number of MPs
objected to the Bill, so it failed to pass at Second
reading on 23 November. It is therefore very
unlikely to progress any further in the current
Parliamentary session, though officially the Bill is
to be read a Second time on Friday 25 January 2019.]
The very next day, Wednesday 24 October, an
amendment, tabled by Stella Creasy MP and Conor McGinn
MP, to the Northern Ireland (Executive Formation and
Exercise of Functions) Bill, which would have
fast-tracked abortion and same-sex ‘marriage’ in
Northern Ireland, was abandoned. Instead, MPs were
presented with a ‘new clause 7’, which stated that
current laws preventing abortion and same-sex 'marriage'
in Northern Ireland are incompatible with human rights
legislation. This was approved by 207 vs. 117 and
added to the Bill as clause 4. The entire Bill was
then overwhelmingly approved (344 vs. 26) to be read a
Third time. It now passes to the House of Lords to
be debated on Tuesday 30 October.
On 30 October, the
Northern Ireland Bill duly entered the House of Lords. Its primary
purpose has always been to seek plans to restore the
power-sharing Executive in Northern Ireland,
clarifying the role of civil servants. During its
Committee stage, peers debated the Bill and notably
Lord Adonis tabled Amendment 10, ‘The guidance may
direct departments after 1 May 2019 not to enforce
sections 58 and 59 of the Offences against the Person
Act 1861’ and Amendment 11, which would have legalised
same-sex ‘marriage’ in the Province. In the
event, Amendment 10 was withdrawn and 11 was not
moved. During that Tuesday night, the
House completed the Second reading, Committee and
Report stages, as well as the Third reading. The Bill was
finally passed and, as both Houses had agreed the
text, it received Royal Ascent on Thursday 1 November.
Neither
of these Bills changes current abortion law. The
second Bill requires the Secretary of State for Northern
Ireland to provide guidance to civil servants and to
produce quarterly reports to Parliament on the supposed
incompatibility between human rights law and Northern
Ireland law on abortion and same-sex ‘marriage’.
The government is now under considerable pressure to
act. This is despite a recent ComRes poll of 1,863
people in England and Wales which revealed that when
offered the choice of either the status quo, tighter
restrictions on abortion, or making abortion available
on demand, or for any reason up to 24 weeks, just 21% of
women and only 26% of men would support the latter
option. Significantly, a total of 67% of women
favoured either the status quo, or a more restrictive
abortion regime. The Westminster Bills are
therefore out of step with the general public’s
thinking. In other words, the people don’t want
abortion to be decriminalised. But make no
mistake, the pro-abortionists are on a roll.
Abortion
law in Northern Ireland
The
1967 Abortion Act does not apply to Northern Ireland. In effect,
abortions in the Province are illegal in all but
exceptional medical and mental health circumstances. That
restriction sticks in the craw of many, including Sarah
Ewart. In
early October, she applied for a judicial review,
seeking a declaration of incompatibility with human
rights law in cases of fatal foetal abnormalities.
In
June, a majority of Supreme Court judges said the
Northern Ireland ban on terminations in cases of rape,
incest or fatal foetal abnormality needed ‘radical
reconsideration’ because the current legal framework was
incompatible with human rights laws. However, the
Supreme Court dismissed the legal challenge by the
Northern Ireland Human Rights Commission by a narrow
majority over a seeming technicality because it said it
had no jurisdiction to consider the case because there
was no actual or potential victim of an unlawful act
involved in it.
It
was 5 years ago, that Ms Ewart travelled from Northern
Ireland for a termination in England after a 20-week
scan revealed that her baby had anencephaly, meaning
that the brain was not developing normally and that the
baby would either die before being born, or shortly
afterwards. Ms
Ewart attended the Belfast High Court on Monday 1
October to seek leave to apply for a judicial review of
the current laws. There
are four respondents in the case, Northern Ireland’s
Secretary of State Karen Bradley, Northern Ireland’s
Department of Justice, the Department of Health and the
Executive Committee.
This ongoing case is being heard by Mr Justice
McCloskey.
Abortion
reversal
The two-pill medical abortion
method means that women, up to 10 weeks into their
pregnancies, first, take a dose of mifepristone, which
blocks the ‘pregnancy hormone’, progesterone. This is then
followed within 48 hours by a dose of misoprostol, a
prostaglandin that causes cervical dilation and
uterine contractions, leading to expulsion of the dead
embryo or foetus.
But what happens if a woman changes her mind
after taking the first pill? Can she
rescue her pregnancy?
Evidence
from the US suggests that many ongoing medical abortions
can be reversed. This
is controversial stuff.
Currently, four States – Arkansas, Idaho, South
Dakota, and Utah – require abortion providers to tell
their patients about reversal treatment which involves
administering repeated doses of progesterone, either
orally or intramuscularly.
The
man behind the reversal procedure is a San Diego doctor,
George Delgado. Until
recently the only supporting evidence for reversal was
his 2012 paper which documented its effectiveness in
only seven pregnancies.
In April, Delgado and six collaborators published
more results as Delgado et al.,
(2018) ‘A case series detailing the successful
reversal of the effects of mifepristone using
progesterone’ in Issues
in Law and Medicine 33: 3-14. It reports on
754 women who requested the treatment in the US between
2012 and 2016. After
a number of exclusions for various reasons (lost
contact, changed minds, and so on) there were 547
patients who had 257 births. So, the
overall rate of a pregnancy continuing rate was 47%. Not
overwhelmingly successful, but better that the 25% of
women who have been reported to give birth if they do
nothing following the administration of mifepristone
alone.
The
procedure has not gone unchallenged. Abortionists
complain about the safety and efficacy of the treatment
and about a lack of research evidence. Of course, at
this early stage, the work depends on observational case
studies rather than a rigorous randomized
placebo-controlled trial, which would, in any case, be
unethical. Essentially,
critics say, it encourages women to use ‘an unproven and
experimental therapy’ in an unmonitored research
experiment. And
they also maintain that State laws which mandate doctors
to inform their patients about the reversal procedure
are creating ‘a disturbing intrusion into the
relationship between physicians and their patients.’ Some even carp
that the journal, Issues
in Law and Medicine, has
ties with an anti-abortion group.
Delgado and his co-authors
conclude that the reversal procedure ‘appears
to be both safe and effective.’ Their 2018
paper closes with a look ahead, ‘We propose that further
research employing randomized controlled trials
comparing progesterone doses and routes of
administration are needed to confirm which mode of
delivery, dose and duration of progesterone therapy is
most efficacious and carries the least burden for the
patient.’ This
story will run and run.
Abortion pills at home
In
August, the UK Government agreed that women in England
could take the second abortion pill, misoprostol, at home. Some described
the move as ‘risky and reckless’. The change
follows considerable pressure from a number of medical
bodies, such as the Royal College of Obstetricians and
Gynaecologists (RCOG) and groups like the British
Pregnancy Advisory Service (BPAS). The Scottish
government approved a similar measure in October 2017,
and the Welsh government followed suit in June 2018.
Section
1 (3) of the 1967 Abortion Act requires that treatment
for abortion can take place only in an NHS hospital or
approved independent sector place. NHS guidance
says the courts have decided this means that both
abortion pills must be taken in hospital or at an
approved clinic where medical supervision is available. However, the
Government has now decided that the second pill can be
taken at home, without proper medical supervision. This is seen
as merely another step towards abortion without any
restrictions.
So
now what happens when things go wrong? Medical help
will not be readily available. Frightened
girls may not follow the packet’s instructions
correctly. And
the problem of disposal of the embryo or foetus still
exists. Is
this a good move for women’s welfare, or is it a cheaper
scheme for the NHS, and a victory for pro-abortionists?
Banning NIPT results
Can medical results
be vetoed? Many
are calling
for
a ban so that parents-to-be cannot be told the sex of
their baby after early blood tests, amid fears they
may lead to abortions of girls. The
relatively new non-invasive prenatal test (NIPT) is
used by the NHS to search for genetic conditions, such
as Down’s syndrome.
However, the test can also determine gender,
though NHS doctors are not meant to reveal this. Moreover,
people can pay around £150 to £200 for a NIPT
privately to discover their baby's gender. All that is
required is a drop of the woman’s blood to be sent in
the post. The
clinic then analyses DNA derived from the baby and the
results can be sent back in a matter of a few days.
The Labour MP Naz Shah, the shadow
women and equalities minister, has said it is morally
wrong for people to use the test to abort pregnancies
based on the outcome.
Yet thousands of British women are using an
online forum to discuss the use of NIPT to determine
gender. Even
so, Ms Shah has clearly stated that cultural practices
in some groupings, like the South Asian community,
have a preference for boys. The
Department of Health said it would continue to review
the evidence.
Buffer zones and abortion clinics
Women’s
groups and some MPs have been calling for protection
around abortion clinics because anti-abortion protesters
have been accused of harassing and intimidating staff
and patients. But
in September, the home secretary, Sajid Javid, ruled out
the need for so-called ‘buffer zones’. He maintained
the move was not necessary because protests took place
at only a small number of facilities – about 36 of the
363 hospitals and clinics in England and Wales have
reported demonstrations outside their facilities. And because
there was little evidence of harassment – gatherings,
where protestors mostly prayed and handed out leaflets, were
small, and displays of graphic images or blocking
patients’ paths were not common. He therefore
concluded that ‘introducing national buffer
zones would not be a proportionate response.’
Abortion moratorium in Russia
During this summer, hospitals in several
Russian regions imposed a moratorium on abortions
during the annual pro-life campaign run by Svetlana
Medvedeva, the wife of the current Russian Prime
Minister and former President, Dmitry Medvedev. Faced
with the lowest birth rate for a decade, the Russian
government is seeking to reverse the county’s
demographic crisis with a $8.6 billion plan to
encourage Russians to have more babies by offering
mortgage subsidies and other social programs.
The short-term abortion ban was not universally
observed across Russia, but it did take place in the
Far Eastern regions of Primorye and Sakha, as well as
Ryazan in central Russia, during the ‘Give Me Life’
campaign, which aims to ‘protect unborn children and
promote family values’.
Nearer to Moscow, the temporary ban was linked
to Russia’s Day of Family, Love and Fidelity. A Ryazan
health department press release stated that, ‘It is
sad to see a woman voluntarily deprive herself of the
joy of motherhood.
No abortions will be carried out in hospitals
during this period [between July 9 and July 15].’ The practice
of placing a moratorium on abortions for two to seven
days – named the
‘days of silence’ – has
been in place since 2011. Seven days
free of abortion is better than none.
Decriminalisation of abortion in
Queensland
After
two days of debate in mid-October, Queensland has become
the latest Australian State to decriminalise abortion. MPs voted 50
to 41 to make the current legislation more permissive
for supporters of abortion and more restrictive for its
opponents. The
Termination of Pregnancy Bill
removes the procedure from the criminal code and allows
abortion on request up to 22 weeks. After 22 weeks
an abortion can be performed with the approval of two
doctors. The
new law forces conscientious objectors to refer women to
a doctor who will perform an abortion. It also
mandates bubble zones of 150 metres around clinics to
protect clients from harassment. New South
Wales is now the only Australian jurisdiction where
abortion is a criminal offence.
Jackie
Trad, the Deputy Premier, welcomed the new law. ‘The right of
women to control their own reproduction, their own
bodies, is such an important part of equality in our
society,’ she said.
‘To prioritise the rights of a foetus above that
of a woman is something that I find offensive.’ Nick Dametto
MP said that his wife fell pregnant while the couple
were in high school and unmarried. ‘It would have
been easier to abort – no one would ever have known. It would have
changed our lives and we would be in a completely
different place today.’
However, he added that he would not be able to
live with the ‘killing of our unborn son or daughter’ on
his conscience. Another
MP, Ted Sorensen, declared that he was a ‘survivor’ of
an unwanted pregnancy.
‘If this law were present in those days, I would
not be alive to speak on behalf of all of the babies who
have the right to live – and I believe that I had the
right to live,’ Mr Sorensen said. ‘I still
believe that.’
Amnesty International and abortion
Amnesty
International delegates from around the world gathered
at a conference in Warsaw between 6 and 8 July. They adopted
new proposals to tackle what they called, ‘the
devastating human rights consequences of misguided
attempts by countries to criminalise and restrict
abortion and to punish people for using drugs.’ Tawanda
Mutasah, Amnesty International’s Senior Director for Law
and Policy, declared, ‘We want to make sure we are well
placed to fight for the human rights of millions of
people whose lives are impacted by how governments
criminalise or restrict access to abortion.’
Representatives
voted to adopt an updated position on abortion that
calls on states not just to decriminalise abortion, but
to guarantee access to safe and legal abortion in a
broad way that fully respects the rights of all women,
girls and people who can get pregnant. It will
replace Amnesty International’s current position on
abortion, which calls for the decriminalisation of
abortion, and access to abortion in a limited set of
cases, which was adopted in 2007. Amnesty
International has declared abortion to be ‘a human
right’ – the organisation is now one of the biggest
promoters of abortion in the world. ‘How,’ you
may ask, ‘can Amnesty claim to be a protector of human
rights while supporting abortion?’ Does Amnesty
not regard unborn children as human?
Robert Winston on IVF
On the 40th anniversary of the birth of Louise Brown, the world’s first IVF baby, on 25 July this year, Professor Lord Robert Winston, the IVF pioneer, gave an interview to The Irish Times (28 October 2018). As ever, he was forthright. He began, ‘The 40th anniversary is a time to celebrate the great happiness of millions of couples. But this achievement … is also a moment for most serious reflection.’
He described a ‘major problem’ with private clinics ‘selling the dream’ to desperate couples, leading people to believe they are much more likely to get pregnant than they really are. ‘The NHS and the HFEA websites are quite self-congratulatory if you look at them, but the reality is, people are being sucked into IVF without a full recognition of exactly how low the success rate is. He believes that, ‘people don't always understand that the chance of getting pregnant from an individual IVF cycle in the UK still only stands at about 21% if you're under the age of 35 – the chances are even lower if you're older.’ Moreover, he maintained that the private sector is on a ‘gravy train’ with IVF with some clinics charging up to £8,000 for a single cycle of treatment. He described the combination of ‘desperation’ from couples and ‘avarice’ from private practices as a ‘dangerous combination’. He went on, ‘The HFEA records success rate per embryo transfer, but that in itself is misleading, because a large number of women start a cycle but never get to the embryo transfer stage, either because their ovaries don't respond or because the eggs don't fertilise.’
‘The first thing we need to change, which is
something we're not doing in reproductive medicine, is
to regard infertility as a symptom. Right now,
we regard it as a diagnosis and it's fundamentally
wrong to offer a treatment on the basis of symptoms –
because the underlying cause of the symptom will
vary…’ ‘In
many cases, in-vitro fertilisation is not the best
[treatment] – but it's the most profit. Unexplained
infertility is a nonsense; it's a failure to make a
diagnosis. People
are reluctant to go through with investigations, which
in my view are justified, because at the moment, so
many patients are failing to get pregnant with an IVF
cycle and then get pregnant after the IVF has
finished.’ And,
‘One of the important issues is making a diagnosis and
finding other more effective simpler remedies, but
most clinics are now geared up to do IVF, so they
don't actually treat the underlying issue.’ Winston
considers that, ‘one of the most common causes of
infertility in women is a hormone deficiency, which is
usually better treated by drugs – yet few clinics
offer this. He
therefore believes it's time to make a change.
The
list of adverse outcomes for children conceived by ARTs
is growing. The
latest comes from a Swiss study entitled, ‘Association
of Assisted Reproductive Technologies With Arterial
Hypertension During Adolescence’ by Journal
of the American College of Cardiology (2018), 72:
1267-1274.
Another almost inconceivable IVF
story
In
September this bizarre case was reported in the media. You couldn’t
make it up. A
wealthy British unnamed couple, described as ‘very rich
and from a notable family’ have created a ‘designer
grandson’ using sperm taken from their dead son. They wanted an
heir and a grandson after their unmarried son, aged 26,
tragically died in a motorbike accident. His body lay
undiscovered for two days after which a urologist
retrieved some sperm and immediately froze it. Nearly a year
passed before the sperm sample was flown to the USA by a
specialist medical courier to an IVF clinic in
California, run by David B. Smotrich MD, FACOG, an
obstetrician and gynaecologist and the founder and
medical director of La Jolla IVF.
Using an American
ova donor and a surrogate mother, a boy was born in
2015. Gender-selection
techniques,
which are not permitted in the UK, were used to
ensure a male heir. The
British couple, who were named as the legal parents,
were present for the birth. According to Dr
Smotrich, the three-year-old is now living in the UK
with his grandparents, who are believed to be in their
fifties. It
is estimated that the procedure, including hospital
fees and payments to the American ova donor and
surrogate, would have cost between £60,000 and
£100,000.
Dr Smotrich said he understood that the
couple’s son had not given formal consent to the
extraction and use of his sperm in the event of his
death, suggesting that those involved in the UK may
have committed a criminal act and could face
prosecution. Moreover,
he stated that the couple had been ‘very specific’
about the type and calibre of the ova donor and the
surrogate, insisting on subjects who matched the kind
of woman they believed their son would have married in
terms of physical looks, intellect and education. Dr Smotrich
said he had no ethical objections to helping the
British couple and confirmed that the remaining sperm
and three more embryos were in cryogenic storage. And though he
knew that gender selection is banned in the UK, he
maintained, ‘It was a privilege to be able to help
them.’ Apparently,
he still receives Christmas cards from the family.
Born to female-only parents
The
rules of mammalian reproduction have apparently been
rewritten – and males can now be written out. For the first
time Chinese researchers have used the DNA of two female
mice to create apparently healthy pups, some of which
matured and produced their own offspring. Baby mice
derived from the combined genetic material of two
fathers were also produced, but these pups lived for
only 48 hours after birth.
The work was carried out by Qi Zhou and his team
at the Chinese Academy of Sciences in Beijing and
published in Cell
Stem Cell, under the title, ‘Generation of
Bimaternal and Bipaternal Mice from Hypomethylated
Haploid ESCs with Imprinting Region Deletions’ by Li et al., (2018)
23: 1-12.
The
headline-grabbing news was that 29 mice were
successfully born to same-sex (bimaternal) female
parents. The
more scientifically-oriented news was that the team
identified, and overcame, factors that makes joint
male-female involvement in reproduction essential for
humans. In
other words, single-sex humans might be able reproduce
in the future, but not any time soon. Females of
other species, such as some birds, reptiles, fish and
amphibians can reproduce alone, but this is a first for
mammals which customarily use sexual reproduction,
namely, when a female ovum is fertilised by male sperm.
The Chinese team set out
to identify the genetic process that takes place at the
point of mammalian conception that demands genes from
both sexes. They
focused on a phenomenon known as ‘genomic imprinting’, a
mechanism that requires mammalian DNA from male and
female and whereby small chemical tags attach to DNA and
turn off certain genes. They
found roughly 100 such genetic tags. Many genes
that are tagged in one sex are untagged in the opposite
sex. In
other words, while mammals receive a full copy of
genetic material from each parent there are some genes
where only a copy from a particular parent will do –
this is said to be imprinted. Combining two
of the same imprinted tagged genes sequences, as would
occur with same-sex parents, would lead to the death of
the embryo. To
overcome this limitation, lab-grown embryonic stem cells
were derived from both murine sperm and ova. These cells
have only one set of chromosomes and, like most cells,
contain genetic regions that can produce the chemical
tags. Using
the process of trial and error, the researchers used the
CRISPR-Cas9 protocol to snip out a single letter of
genetic code from three imprinted genetic regions of the
female haploid embryonic stem cells (which like sperm
and ova contain only one copy of each chromosome), in
batches, searching for groups that could be removed
without stopping the production of a healthy embryo. They then
imitated fertilisation by combining an edited stem cell
from a female mouse with the ovum from another female to
create pups from two mothers. They also took
a stem cell from a male mouse and injected it, along
with another male’s sperm, into a denucleated ovum to
create offspring from two fathers. As a result of
deleting just 3 regions, the scientists managed to
produce 210 embryos which led to the birth of 29 live
bimaternal mice, 7 of which went on to have their own
pups. The
process was more difficult with male mice because 7
regions had to be deleted before they were able to
produce 477 embryos which resulted in only 12 bimaternal
pups, of which only 2 survived for up to 2 days.
This work
demonstrated a new and clear way to produce offspring
between same-sex mammals. And it
revealed some of the most important genetic regions
that prevent mammals from reproducing without the need
for two individuals of the opposite sex. The
co-senior author of the study, Qi Zhou, said, ‘We saw
that the defects in bimaternal mice can be eliminated
and that bipaternal reproduction barriers in mammals
can also be crossed through imprinting modification.’ However,
most of the embryos produced were abnormal and only a
14% bimaternal success rate and a 2.5% bipaternal rate
were achieved. And
there was no convincing long-term evidence that the
mice were ‘normal’.
Yet others said, ‘Creating genetic offspring
from two mice of the same sex is an exciting
achievement.’ Others
said, ‘There is a chance in the long run that the
technique could be developed to apply to humans.’ Others
warned that, ‘The scientific challenges and legal
barriers that would need to be to overcome to make
this possible in humans are huge.’ Significant
ethical and safety concerns would need to be
overcome.’ And
others said, ‘We should start discussing whether this
is a noble endeavour.’
Towards artificial ovaries
In a bid to enable women to have children after
fertility-damaging treatments, a research team led by
Susanne Pors at the
Rigshospitalet in Copenhagen has created an
artificial ovary from human tissue and ova. These
bio-engineered ovaries were shown to keep ova alive
for a few weeks.
Such a strategy raises the possibility that
such ovaries, when transplanted, could recover
fertility in women who have undergone treatment by
chemo- and radiotherapy as well as those suffering
from multiple sclerosis, beta thalassaemia, or even
early menopause.
The work was presented at the 34th
Annual Meeting of the European Society of Human
Reproduction and Embryology in Barcelona in July.
It was entitled,
‘Early-Stage Research Shows Potential of Artificial
Ovary for Fertility Preservation Without the Risk of
Reintroducing Malignancy.’
Women with a cancer
diagnosis can already have ovarian tissue removed and
frozen and then transplanted once their treatments are
over. Thus
their fertility is safely restored. But for some
high-risk patients, ovarian cancer or leukaemia can
permanently damage their ovaries. The use of
artificial ovaries could be a safer option. The protocol
involves stripping ovarian tissue of cells to create a
scaffold. This
is then seeded with 20 human follicles, the sacs that
contain immature ova.
Such an artificial ovary implanted in a mouse
enabled 25% of the follicles to survive for at least
three weeks, by which time blood vessels had started
to infuse the ovary, the researchers called
this ‘the point of biofunctionality’. Although this study confirms
a proof of concept, scientists reckon it will be
another 5 to 10 years before human trials can be
undertaken. It
could also obviate IVF.
You read it here first.
Saviour siblings
It is
a long time since saviour siblings were in the news
headlines. In
mid-August, the news that an Australian couple, who
genetically engineered their baby to become a
bone-marrow donor for one of their other five children,
has prompted renewed debate about designer babies. Olivia and
Andrew Densley from Melbourne spent A$100,000 (£57,000)
on repeated IVF treatments before obtaining a matching
embryo to save their fifth child, Fletcher, aged four,
who suffers from the potentially deadly illness known as
Wiskott-Aldrich syndrome.
This condition is characterised by a deficient
immune system and an inability to form blood clots,
causing dangerous bleeding.
A bone marrow transplant offered the only hope of cure. The Densley family undertook a worldwide search for a matching bone marrow donor – it proved to be fruitless. The couple then decided to create their own compatible saviour sibling. In mid-August, their daughter, Lilliahna, was born. The life-saving bone marrow for Fletcher will be extracted from her when she reaches 22 lb in weight. Oh, the problems of consent, Lilliahna’s possible resentment concerning her utility, the eugenic nature of IVF-PGD and its destruction of ‘unsuitable’ embryos, the knowledge that Mrs Densley already suffered from Wiskott-Aldrich syndrome, and so on, and so on. If you want to discuss a contentious bioethical topic, try saviour siblings.
Genetic Engineering
The Nuffield Council on Bioethics
Report
Should
we,
or should we not, be allowed to modify human DNA in
future children? On
17 July, the UK’s influential Nuffield Council on
Bioethics said yes by implicitly endorsing (p. 75)
‘heritable genome editing interventions’. It declared
(p. 96) the practice of altering the DNA of a human
embryo as ‘morally permissible’ ‘in certain
circumstances’ (p.158).
After 20 months of consultation with many experts
in the UK and beyond, the Council’s 183-page Report,
‘Genome editing and human reproduction: social and
ethical issues’ [see here],
has been published.
Its main conclusion (p. 154) is, ‘We can, indeed,
envisage circumstances in which heritable genome editing
interventions should be permitted.’
The
Council
had four terms of reference (p. iv). First, ‘To
identify and define ethical questions raised by recent
developments in biological and medical research that
concern, or are likely to concern, the public interest.’ Second, ‘To
make arrangements for the independent examination of
such questions with appropriate involvement of relevant
stakeholders.’ Third,
‘To inform and engage in policy and media debates about
those ethical questions and provide informed comment on
emerging issues related to or derived from its published
or ongoing work.’ Fourth,
‘To make policy recommendations to Government or other
relevant bodies and to disseminate its work through
published reports, briefings and other appropriate
outputs.’
The
Report
recommends (p. vii) that two overarching principles
should guide the use of ‘heritable genome editing
interventions’ for them to be ethically acceptable. First, ‘that
such interventions are intended to secure, and are
consistent with, the welfare of a person who may be born
as a consequence.’
Second, ‘that any such interventions would uphold
principles of social justice and solidarity – by this we
mean that such interventions should not produce or
exacerbate social division, or marginalise or
disadvantage groups in society.’
The
Report
further recommends that heritable genome editing
interventions should be permitted only when three
conditions have been satisfied. First (p.
135), ‘there should be sufficient opportunity for a
broad and inclusive societal debate.’ Second (p. 159),
‘research to establish the clinical safety and
feasibility of genome editing.’ Third (p.
100), ‘measures to monitor the social consequences and
to mitigate any adverse effects are in place.’
Overall,
the
Report states (p. xviii) that if ‘heritable germline
genome editing’ were to be permitted, it should be under
three controls. First,
‘not be permitted until risks of adverse outcomes have
been thoroughly assessed, and then only on a
case-by-case basis.’
Second, ‘licensed and regulated under the system
currently overseen by the HFEA.’ And third,
‘within the context of a carefully monitored study, with
comprehensive follow-up arrangements in place.’
The
Report
has not gone unnoticed.
Its endorsement of human genome editing has drawn
fire from several experts – including at least one who
consulted on the Council's previous 2016 Report. Critics, for
example, include Stuart A. Newman, Professor of Cell
Biology and Anatomy at New York Medical College, who
said, ‘I'm very troubled by it. I think it's
very irresponsible of them to make that pronouncement. I think that
these methods are dangerous and in fact, there is no
child there, there is basically a fertilized egg and
they're saying that the child has an interest and the
interest is to be experimented on. These
experiments are very chancy and there is really no
guarantee that the developing embryo won't turn out more
impaired than the way it started. I really don't
understand the rationale at all.’
And
Dr David King, Director of Human Genetics Alert,
claimed, ‘This is an absolute disgrace. We have had
international bans on eugenic genetic engineering for 30
years. But
this group of scientists thinks it knows better, even
though there is absolutely no medical benefit to this
whatever. The
Nuffield Council doesn't even bother to say no to
outright designer babies.
The people of Britain decided 15 years ago that
they don't want GM food.
Do you suppose they want GM babies?’ And Marcy
Darnovsky of the Center for Genetics
and Society in California, commented that the Report
acknowledged that if reproductive gene editing were
permitted, it would be used for enhancement and cosmetic
purposes. ‘They
dispense with the usual pretence that this could – or,
in their estimation, should – be prevented. They
acknowledge that this may worsen inequality and social
division, but don’t believe that should stand in the
way. In
practical terms, they have thrown down a red carpet for
unrestricted use of inheritable genetic engineering, and
a gilded age in which some are treated as genetic
“haves” and the rest of us as “have-nots”. The bottom
line is all too clear.
Sadly, the Nuffield Council on Bioethics has
given its blessing to an unneeded and societally
dangerous biotechnology, one that could be leveraged by
privileged elites seeking purported genetic improvements
to ensure that their children are treated as superior to
the rest of us.’
For
many
critics, the big issue is one of burdening future
generations with possibly dangerous genomic alterations
without their consent.
This they say is unconscionable. And there is
also that most vexed question about genome modification
that is not for therapeutic reasons – to eliminate genes
causing disorders – but for enhancement – attempting to
improve a child’s intelligence or physical appearance. Can these
issues be bioethically justified?
While the Nuffield Report is
purely advisory, most of its recommendations on
similar topics have eventually become law in the UK. For this
reason, its advice to the British government is of
global significance.
Germline engineering, as this technique
is sometimes called, was for a long time the red line in
biology. Any changes made would become part of the
genome of the individual, to be passed on to future
generations. The uncertainties and risks were
deemed so great that it should never be attempted.
How times have changed! Are we in danger of creating
a eugenic mentality that aims to improve the gene
pool, but instead creates social stigmas and social
privileges for people with certain genetic qualities?
Base editing (BE)
Gene
editing
is currently most commonly undertaken using the
CRISPR-Cas9 technique.
Base editing (dCas9) represents a different
approach. Instead
of inducing a snip in DNA at the desired site, as Cas9
does, and then allowing the cell's natural repair
mechanisms to re-join the DNA with random edits, dCas9
changes a single target letter without causing a break. This is
thought to result in fewer off-target effects, which
could improve clinical safety.
BE
was
developed in 2016 by David Liu at Harvard University in
Cambridge, Massachusetts.
He explained that, 'Most human genetic variants
that cause disease are point mutations –
a
single base-pair that, for whatever reason, has been
changed to a different base-pair. So we set out
to take a new approach to genome editing that would be
especially good at correcting point mutations.’ BE using
CRISPR-dCas9 can be likened to a scalpel, whereas gene
editing using CRISPR-Cas9 is more like an axe.
Base editing in action
Marfan syndrome is an
autosomal dominant disorder with a wide range of
symptoms, including heart problems and those affected
are typically abnormally tall and slender. It is thought
to be caused by a single base change in the patient’s
DNA – from a 'healthy' T to a pathogenic C in a gene
known as FBN1.
FBN1 codes a protein called fibrillin,
which is a key component of connective tissues. Without
fibrillin these tissues do not form properly.
A team of researchers from Shanghai
Tech University and elsewhere in China have
reported the successful correction of this mutation
responsible for Marfan syndrome in viable human embryos
by base editing. The
study was published in the journal Molecular Therapy (2018, 26: 1-7) under the title, ‘Correction
of the Marfan Syndrome Pathogenic FBN1 Mutation
by Base Editing in Human Cells and Heterozygous Embryos’
by Yanting Zeng et
al.
Healthy donor ova were
fertilised by IVF with sperm from a man known to have
the disease. A
total of 18 resulting embryos were injected with
base-editing CRISPR-dCas9 components. This procedure
accomplished the required T-to-C change. All of the
treated embryos exhibited a change at the target site. In 16 out of
18 instances the change was a reversion of the C back to
a T, while the other two were changed, but incorrectly. No adverse
off-target effects were recorded and the editing efficiency
rate was about 89%. This
apparently safe and efficient work is regarded as a
pilot study providing proof of concept rather than as a
clinical treatment for Marfan – that will be many years
away. Meanwhile
bioethical problems abound – this study used IVF and resulted in ‘heritable
germline genome editing’.
Who owns CRISPR-Cas9?
We’ve
been
here before. Way
back in 2012, Jennifer Doudna and Emmanuelle
Charpentier, researchers at the University of
California, Berkeley (UC), filed a patent for their
discovery of CRISPR-Cas9 and its ability to edit DNA. Subsequently,
Feng Zhang's team at the Broad Institute in Cambridge,
Massachusetts used CRISPR-Cas9 to edit the genomes of
eukaryotic cells and applied for a fast-tracked patent
application, which was processed before UC's. Enter the
lawyers.
This
situation
sparked a long-running dispute, which has probably been
settled on 10 September in favour of the Broad
Institute. The
Court of Appeals for the Federal Circuit in Washington
issued the ruling after hearing arguments in April. UC brought the
case, appealing the 2017 decision of the US Patent Trial
and Appeal Board (PTAB) to award a patent to the Broad
Institute. The
quarrel centred on who had the rights to charge fees for
the use of this technology, which has an extremely high
commercial value. As
an indication of the latter, it is thought that Broad’s
legal fees have already exceeded US$10 million.
Is CRISPR-Cas9 editing safe?
Scientists from the Wellcome
Sanger Institute at Cambridge have reported that in
three cell types, derived from mice and humans,
CRISPR/Cas9 can frequently cause extensive mutations. Published in
Nature Biotechnology
(2018, 36: 765-771)
the study, ‘Repair
of double-strand breaks induced by CRISPR–Cas9 leads
to large deletions and complex rearrangements’ by
Kosicki et al.,
found that many of the cells had large genetic
rearrangements, such as DNA deletions – often several
thousand DNA letters long – and insertions – complex
rearrangements of DNA sequences – equivalent to damage far greater than
previously reported.
In addition, some of these
changes were too far away from the target site to be
seen with standard genotyping methods. The
researchers stressed that standard tests for detecting
DNA changes may miss finding these sites of genetic
damage. Obviously,
such unexpected damage could lead to dangerous changes
in some cells which would have safety implications for
future gene therapies using CRISPR/Cas9. As the
researchers warn, ‘The observed genomic damage in
mitotically active cells caused by CRISPR–Cas9 editing
may have pathogenic consequences.’ Clearly,
these unwanted edits are a problem and their cause
deserves more attention.
Polygenic scores
Here’s something new. For the last
20 or so years, researchers
have struggled to explain numerically how likely we are
to suffer from heritable conditions, such as heart
disease, diabetes and schizophrenia. Polygenic
scores add together the infinitesimal contributions of
tens of millions of locations, or spots, on our genome
to create some of the most powerful genetic diagnostics
to date. Or,
at least, that is the hope.
One of the maestros behind
this innovative science is Sekar Kathiresan,
a
geneticist at the Massachusetts General Hospital in
Boston. The
polygenic risk scores he has developed are part of a
cutting-edge approach in the hunt for the genetic
contributors to common diseases. He has been known to
look at as many as 6.6 million spots to calculate a
person’s risk of developing, for example, coronary
artery disease. Kathiresan
has found that combinations of single DNA-letter
differences from person to person in these locations can
help to predict whether someone will succumb to one of
the leading causes of death worldwide. It is
needle-in-a-haystack science, and it is anyone’s guess
what the majority of all those As, Cs, Ts and Gs are
doing. Nevertheless,
Kathiresan maintains that, ‘you can stratify people into
clear trajectories for heart attack, based on something
they have fixed from birth.’
This is big data science. Large data
repositories, such as the UK Biobank, already contain
vast quantities of health information alongside DNA data
from hundreds of thousands of people. Now such data
have been analysed from more than a million participants
with the aim of detecting tiny, tiny differences and
effects. Supporters
say that polygenic scores could be the next great stride
in genomic medicine, but the approach has generated
considerable debate.
How might the scores be used, advantageously and
disadvantageously?
How will participants interpret the complex and
sometimes equivocal results? Are the
databases too limited in ethnicity and geographical
diversity?
Whatever
the
bioethical quandaries, the science is already out of the
lab and into the home – at least one US company is
offering consumer testing.
At the end of December 2017, Myriad Genetics
became the first large diagnostics company to introduce
a polygenic risk test to the US market. Called
riskScore, it measures 86 DNA variants and combines them
with a person's family and medical history, to determine
a woman's five-year and lifetime risk of breast cancer.
So,
here
is the new term to learn.
It is called ‘genome-wide association study’, or
GWAS for short. GWAS
has two main applications.
First, it can help understand the underlying
biological architecture of disease and human variation.
Second, it
can predict who is most at risk of developing
conditions, like heart disease and diabetes, potentially
even before birth. And
currently all that is required is a cheek swab. So GWAS is
'hot-button' science.
In 2007, there were 240 published research papers
that mentioned GWAS, in 2017, the figure was more than
3,800.
Gene editing of human embryos
Japan
is
set to allow the gene editing of human embryos. An expert
panel, representing the country’s health and science
ministries, released new guidelines in September. Although the
country regulates the use of human
embryos for research, until now there have been no
specific guidelines on using novel tools, such as
CRISPR–Cas9, capable of making precise DNA
modifications.
The new guidelines
will allow for research to be carried out on
early-stage embryos, with scientists hoping to gain
insight into early human development and perhaps
eventually fix genetic mutations that cause inherited
diseases. As
ever, bioethicists are concerned that the technique
could be used to alter the embryos for non-medical
reasons. While
the guidelines would ban the manipulation of human
embryos for reproduction, they will not be legally
binding. Currently
these proposed guidelines are open for public
consultation and their implementation is expected in
early 2019.
It
was
in April 2015, that researchers in China first reported
using CRISPR-Cas9 to edit human embryos. Such editing is still banned in most
countries, though China,
the United States, Sweden and the UK sanction it – restrictions
in the latter were relaxed in February 2016.
Gene-editing human sperm
Would it be more
bioethically acceptable to gene edit reproductive cells,
namely, sperm and ova, rather than human embryos? If so, then
there should be encouragement for the recent work
published by Diane Choi and her team at Weill Cornell
Medicine in New York City.
In a poster (P-794) entitled, ‘Feasibility of
CRISPR-Cas9 on the human sperm cell’ and presented at
the annual meeting of the European Society of Human
Reproduction and Embryology during July 2018 in
Barcelona, the US scientists used
CRISPR-Cas9
editing to directly target a gene associated with male
infertility in mature sperm cells. They found
that a single 1100-volt electrical pulse, for just 50ms
duration allowed the CRISPR components to break through
the tough exterior of the sperm cells without killing
them. Although
sperm motility was reduced by half, as the strongest and
healthiest sperm had been selected, their swimming
ability was still efficient enough to be able to
fertilise an ovum without the need for ICSI.
In theory, all
single gene disorders transmittable by the male could be
treated if CRISPR-Cas9 could be successfully used on
sperm. An
additional advantage of targeting sperm rather than
embryos is that the cells of the latter are dividing
rapidly so that the editing process may be incomplete
leading to mosaicism.
Moreover, if successful, this approach could lead
to treating genetic diseases passed on by fathers, such
as cystic fibrosis, sickle cell anaemia and muscular
dystrophy.
Stem–cell
Technologies
California dreamin’
The
Mamas and the Papas recorded a song with this title in
1965 – yes, I’m a true child of the Sixties. But now, in
2018, California has been caught dreamin’ in another
context.
Back
in 2004, the Californian dreamers voted 59% to 41% for
Proposition 71, an amendment to the State constitution
that created the California Institute for Regenerative
Medicine (CIRM). It
would cost the Sunshine State taxpayers US$3 billion
with another $3 billion in interest. But the dreamers
were promised stem-cell treatments, especially those
using embryonic stem cells, beyond their wildest dreams. Now the CIRM’s
funding has nearly run out and its supporters plan to
ask voters to authorise another $5 billion in funding in
2020.
OK, so the money
has been mostly spent.
On what? And
what about those promises? The
easily-led Californians were told that new, life-changing
therapies would emerge in just a few years. And the
project would create thousands of jobs and return
the State's investment more than seven times over. Maybe. But, of
course, it has not happened that way. Instead no
federally-approved treatments have been produced. And without
marketable therapies, the scheme will be a financial
disaster. CIRM
has funded nearly 50 clinical trials, but just four
have so far been completed. The expected
$1.1 billion in royalties within 35 years has amounted
to just one single payment of $190,000. So what went
wrong? In
short, embryonic stem-cell research was over-hyped. It did not
deliver, it never would, and it never will. Other
approaches, using adult and induced pluripotent stem
(iPS) cells have been so much more promising and
therapeutic. The
Californians made the wrong choice. They
believed the propaganda.
They expected a rich return and rapid remedies. Their dreams
have not come true.
They are not dreamin’ so much now!
Parkinson’s and iPS cells
At the end of July,
researchers in Japan
announced the launch of a clinical trial to treat
Parkinson’s disease with neurological material
derived from induced pluripotent stem (iPS) cells. Parkinson’s
disease results from the death of specialized cells
in the brain that produce the neurotransmitter,
dopamine. A
lack of dopamine leads to a decline in motor skills,
resulting in difficulty walking and involuntary
trembling. As
the disease progresses it can lead to dementia.
The
trial strategy is to derive dopaminergic progenitors
from iPS cells and inject them into the putamen, a
round structure located at the base of the forebrain.
Surgeons
will drill two small holes through the patient’s skull
and use a specialized device to inject roughly 5
million reprogrammed cells. The trial is
being led by Jun Takahashi, a neurosurgeon at Kyoto
University's Center for iPS Cell Research and
Application (CiRA), in cooperation with Kyoto
University Hospital.
Studies with animals have shown that the
progenitors can differentiate into dopaminergic
neurons inside the body and then engraft into the
brain. Takahashi’s group reported last year that
monkeys with Parkinson’s had shown significant
improvements with this treatment, lasting for at least
2 years. The
team plans to recruit seven human patients and follow
them for 2 years post-injection.
This
is the third human trial using iPS cells approved in
Japan. The
first, using retinal cells derived from iPS cells to
replace eye tissue damaged by age-related macular
degeneration (AMD), was launched in 2014 and is being
led by Masayo Takahashi of the RIKEN Center for
Developmental Biology in Kobe, who just happens to be
Jun Takahashi’s wife. The
AMD treatment was initially reported to be safe,
though there has been one reported adverse
event. Earlier this year, a team at Osaka
University in Japan won conditional approval for an
iPS cell-based study for ischaemic heart disease.
Blindness and iPS cells
Scientists have reversed congenital blindness in mice by reprogramming supportive cells in the retina, called Müller glia, into rod photoreceptors. Enabling the eyes to regain their self-healing properties could produce regenerative therapies for blinding diseases, such as age-related macular degeneration and retinitis pigmentosa – it could give hope to millions suffering from vision impairment.
Researchers have
long studied the regenerative potential of Müller glia
because in other species, such as zebrafish, they can
divide in response to injury and turn into
photoreceptors and other retinal neurons. Zebrafish,
because they retain their retinal stem-cell population
so, unlike mammals, they can regain vision after
severe retinal injury. In
the laboratory, scientists plan to coax mammalian
Müller glia to regain their cell repair machinery to
behave more like fish. But
it first requires injuring the tissue, a rather
counterproductive procedure.
There are many different kinds of genetic
disease that cause blindness, each requiring its own
treatment. Although
it remains a long way from human trials the scientists
behind the latest research, published in Nature (2018,
560: 484–488) by Yao et al., and
entitled, ‘Restoration of vision after de novo genesis
of rod photoreceptors in mammalian retinas’, believe
their technique could
provide a more general way of restoring sight,
irrespective of the cause of blindness.
This latest work
was led by Bo Chen, director of the Ocular Stem Cell
Program at the Icahn School of Medicine at Mount
Sinai, New York.
His team showed that by transferring a gene into the
retinal cells and then reprogramming them, they were
able to restore lost photoreceptors in blind mice,
which regained their vision after about six weeks. They only
restored rods, which are responsible for vision in low
light. But
they believe that keeping rods will also help protect
cones, the other important type of retinal cell.
Humans have the same retinal machinery, but do
not have this ability to use it – for some reason it is inhibited. If the
technique could turn on this human stem-cell repair
function, it could help reverse the damage done by
conditions like, for example, macular degeneration,
which affects about half a million people in the UK.
According
to
Thomas Greenwell, of the US National Eye Institute,
‘This is the first report of scientists reprogramming
Müller glia to become functional rod photoreceptors in
the mammalian retina.
If rods can be regenerated from inside the eye,
this might be a strategy for treating diseases of the
eye that affect photoreceptors.’ Helen Lee,
from the Royal National Institute of Blind People, said,
‘Clearly it is still at a very early stage, but at some
point in the future stem-cell treatment may become part
of the armoury of treatments for sight-threatening eye
conditions.’
A new method for iPS cells
The addition of so-called Yamanaka
factors, critical genes, has been the means of
reprogramming a variety of cells into induced
pluripotent stem cells (iPS cells). For the
first time, a group of scientists from Finland, Sweden
and England have succeeded in converting human skin
cells into pluripotent stem cells by activating the
cell's own genes.
The
work entitled, ‘Human pluripotent
reprogramming with CRISPR activators’ was published in
Nature
Communications (2018,
9: 2643) by
Weltner
et al.
This
was achieved by using CRISPR-Cas9-based gene activation
(known as CRISPRa) and a blunted version of the Cas9
'gene scissors' that does not cut DNA and can therefore
be used to activate gene expression without mutating the
genome. In
addition, multiple genes can be targeted at the same
time. So
reprogramming based on activation of endogenous genes,
as opposed to Yamanaka exogenous factors, rather than
overexpression of transgenes is also theoretically a
more physiological way of controlling cell fate and may
result in more normal cells. Reprogramming
efficiency was improved by additionally targeting a
conserved Alu-motif enriched near genes involved in
embryo genome activation (EEA-motif) – this is a genetic
element found to regulate the earliest steps of human
embryo development after fertilization.
Stem cells from umbilical cord
blood
It
has long been known that human umbilical cord blood
(hUCB) is rich in stem cells. Researchers
from the Stowers Institute for Medical Research
in Kansas City, Missouri and their
collaborators from elsewhere have identified a way to
expand the numbers of blood-forming, adult stem cells
from hUCB. This
could make these cells available to more people, and
be more readily accepted in those who undergo adult
stem-cell treatments for conditions, such as
leukaemia, blood disorders, immune system diseases and
other types of cancers, but who cannot obtain an
appropriate and available bone marrow match.
Life-saving bone
marrow transplants have been the common practice for
decades, but they do not work for everybody. Only 30% of
patients have a bone marrow donor match available in
their families. Moreover
at least 170,000 people in the USA are expected to be
diagnosed during each year with a blood cancer, such
as leukaemia, lymphoma and myeloma. Adult stem
cells from umbilical cords are more likely to be a
match for more people because there are fewer
compatibility requirements than for a bone marrow
transplant. But
adult patients need two cords' worth of blood per
treatment, and there are not enough cord units
available for everyone who needs the treatment. Hence the
drive to expand the stock.
The
study in question is ‘Suppression of m6A reader Ythdf2
promotes hematopoietic stem cell’ by Zhenrui Li et al., and
published in Cell
Research (2018, 28: 904–917).
Bio-engineering an oesophagus
Around one in 3,000
babies is born each year with abnormalities of the
oesophagus, usually involving either a gap between the
upper and lower section, or where it does not connect
with the stomach.
Scientists at Great Ormond Street
Hospital (GOSH) and the Francis Crick Institute in
London have grown a bio-engineered oesophagus which was
successfully implanted into mice. The work was
published in
Nature Communications (2018, 9:
4286) under the title ‘Multi-stage bioengineering of a
layered oesophagus with in vitro expanded muscle and
epithelial adult progenitors’ by Luca Urbani et al.
The
team used a rat oesophagus, which they first stripped of
its cells, leaving behind a collagen scaffold. Then they
seeded it with stem cells obtained from early-stage
muscle and connective tissue from mice and humans, and
other early rat cells, which went on to form the lining
on the inside of the organ. This use of
stem cells from different species would enable the
researchers to differentiate between the origins of each
tissue type which developed. Finally, 2 cm
sections of the oesophagus were implanted into the
abdomen of mice.
Paola Bonfanti, the
group leader, said, ‘We were amazed to see that our
engineered tissue had both the structure and function
of a healthy oesophagus, and hooked up with nearby
blood vessels within a week of transplantation.’ The sections
of oesophagus were capable of muscle contraction,
which is needed to move food down to the stomach. Paolo De
Coppi, co-author commented, ‘This is a major step
forward for regenerative medicine, bringing us ever
closer to treatment that goes beyond repairing damaged
tissue and offers the possibility of rejection-free
organs and tissues for transplant.' The eventual
aim would be to create bio-engineered organs from a
pig oesophagus, which would be injected with a
patient's own stem cells, in order to minimise the
risk of rejection.
This field of
bio-engineered organ transplants suffered a major
setback in 2016 when a surgeon in Sweden, Paolo
Macchiarini, was accused of falsifying
his research. Of nine of his
patients, who received a synthetic windpipe, seven
died, and the two survivors had the organ replaced
with a donor trachea.
The London team say that scandal reinforced
their determination to proceed cautiously.
Disgraced stem-cell researchers
What’s up with
stem-cell researchers?
Are they a cohort prone to cheating? Does their
research have such potent potential that they are
easily distracted by dreaming of huge grants and Nobel
Prizes? Whatever
the reasons they do seem to have an extraordinary
number of retractions of their research papers.
For
example, Ole Petter Ottersen, the president of the
Karolinska Institute in Sweden has recently ruled that
seven of its researchers, including the now disgraced
surgeon Paolo Macchiarini, were ‘guilty of scientific
misconduct’. In
2017, Ottersen was given the task of cleaning up the
famed Institute after a scandal over bio-engineered
implants damaged its reputation. He has asked
for six articles to be retracted, including two
published in the Lancet. Controversially,
he included in his list one of Macchiarini’s co-workers,
Karl-Henrik Grinnemo, who had initially alerted the
Institute to defects in the articles as long ago as
2014. In
his retraction request for the 2011 paper in the Lancet (2011,
378:1997-2004),
‘Tracheobronchial
transplantation with a stem-cell-seeded
bioartificial nanocomposite: a proof-of-concept
study’, Ottersen
stated that, ‘No ethical permit had been obtained for
the underlying research.
The research was carried out without sufficient
support by preclinical data, and the paper presents its
data in a way that is unduly positive and uncritical. The clinical
findings reported are not supported by source data.’ Macchiarini’s
three co-authors of the Review paper, ‘Engineered whole
organs and complex tissues’ published in the Lancet (2012, 379:
943-952), were found not blameworthy and not
guilty of misconduct.
Yet
another example of stem cell cheating has been
attributed to a world-renown cardiac researcher, Piero
Anversa. He rose to prominence for his work on the
regeneration of heart tissue by stem cells. He
appeared to show that the heart’s capacity for
self-repair was generally underestimated. Yet some
of his critics said that the idea of regenerative stem
cells existing in the heart was implausible. Now,
officials from his previous places of work, Harvard
Medical School and the Brigham and Women’s Hospital in
Boston, have asked that 31 of his papers be retracted
from journals. The papers in question, ‘included
falsified and/or fabricated data.’ In addition,
the New England Journal of Medicine has
retracted one paper of Anversa’s papers and issued an
‘expression of concern’ about two others. The NEJM
retracted paper was the 2011 study, ‘Evidence for human
lung stem cells’ (2011, 364: 1795-1806).
Now comes news (The
Daily
Telegraph, 31 October 2018) of a cover-up by
stem-cell scientists based at University College London
(UCL). The
team, led by Professor Martin Birchall, was proposing to
conduct a multi-million pound clinical trial using
tracheas, bio-engineered with stem cells, to treat
patients with failing windpipes. Their grant
application was based on their experience with this
novel surgery. But
they failed to disclose that two of their previous
patients had died soon afterwards. Miss Shorten,
a 19-year-old, had the operation in 2010 at the Careggi
Hospital in Florence, but her new trachea collapsed, she
spent 6 months in intensive care and was given a plastic
trachea, but she died four months later. Miss Davison,
aged 15, had undergone a tracheal transplant in 2012 at
Great Ormond Street Hospital (GOSH), but it too
collapsed, she suffocated and suffered irreversible
brain damage and died 13 days later. Neither of
these deaths was mentioned in the grant application, in
fact they were described as ‘successful’ in promotional
literature. The
team’s promised £4.7m of UK funding has been withdrawn
and an additional £6m EU-backed trial is now unlikely to
go ahead. How
did these deceitful research workers ever receive
approval for their project? Professor
Patricia Murray, a stem-cell biologist from Liverpool
University, has taken a great interest in this story. She said, ‘The
reason is because they basically lied about patient
outcomes and omitted adverse outcomes. If they had
been accurate about what happened and told the truth, I
don’t think they would have got the funding.’ Various
investigations into these matters are ongoing.
It is to be hoped that this sad litany of stem cell
dishonesty has come to an end. But that
seems a somewhat forlorn hope. Scientists,
like many others, can be driven people, and both
internal and external pressures to continually produce
astounding results, to win prizes and to secure
grants, can make ‘cutting corners’ very tempting. And cutting
corners can so easily grow into bold-faced cheating. When science
becomes fraudulent, we all suffer.
Euthanasia
and
Assisted Suicide
Clinically-assisted nutrition and
hydration (CANH)
On Monday 30 July, Lady Black delivered a
landmark judgement of the Supreme Court with profound
implications on how we value human life. It removed
the previous requirement to obtain legal sanction for
every decision to withdraw clinically-assisted
nutrition and hydration (CANH) from people who lack
capacity through ‘prolonged disorders of
consciousness’ (PDOC).
Prior to
this ruling, based on the 1993 case of Anthony Bland,
brain-damaged patients in a persistent vegetative
state (PVS) or a minimally conscious state (MCS) were
able to have their cases heard by the Court of
Protection. This
sensible pathway was enshrined in the 2005 Mental
Capacity Act. PVS
and MCS patients are typically regarded as unaware,
though they can breathe without the use of a
ventilator and they require food and fluids to be
administered by tube, known as CANH. If CANH and
good care are provided PVS and MCS patients may live
for many years. Some
patients may even regain a degree of awareness. This new
Supreme Court ruling effectively deprives these
patients of the opportunity to recover and sets a
dangerous precedent.
It is
difficult to understand how the best interests of the
patient can be served by withdrawing CANH. Yet the
Supreme Court has now said that it is acceptable for
the patient to ultimately die as a result of
starvation and dehydration, crucially, without
applying to the Court of Protection. In other
words, it will not be their underlying condition which
would be the cause of death. Yet, in
welcoming the move, the
British Medical
Journal stated, ‘This represents the culmination
of a paradigm shift over the past six years, moving
from a focus on a patient’s diagnosis and level of
awareness to a focus on the patient’s best interests.
In effect
it returns clinical decision-making to the clinical
team and patients’ families.’
The judgment confirms that there is now, ‘no
requirement in domestic law for an application to the
court’ and that, ‘the combined effect of the 2005
Mental Capacity Act, the Mental Capacity Act Code, and
the professional guidance, particularly that emanating
from the General Medical Council’ provides a sound,
protective regulatory framework. Lady Justice
Black concluded that, ‘Existing law and guidance are
sufficient to ensure good practice, primarily through
using the best interests process.’
Starving and dehydrating patients for a week or
two until they die – can that really be
in anyone’s best interests? And it is
estimated that there are around 24,000 people
in the UK in PVS and MCS. Some will see
this ruling as compassionate and humane, others as the
removing of a vital legal safeguard for a highly
vulnerable group.
The case of Mr Y
The Supreme Court
ruling, discussed above, was triggered by an appeal on
behalf of Mr Y, a banker. The
following is verbatim from the Press Summary published
by the Supreme Court on 30 July 2018.
‘The question in
this appeal is whether a court order must always be
obtained before clinically assisted nutrition and
hydration (“CANH”), which is keeping a person with a
prolonged disorder of consciousness (“PDOC”) alive,
can be withdrawn, or whether, in some circumstances,
this can occur without court involvement.’
‘In June 2017 Mr Y,
an active man in his fifties, suffered a cardiac
arrest which consequently led to extensive brain
damage due to lack of oxygen. He never
regained consciousness following the cardiac arrest
and required CANH to keep him alive. His treating
physician concluded that, even if he regained
consciousness, he would have profound disability and
would be dependent on others to care for him for his
remaining life. A
second opinion from a consultant and professor in
Neurological Rehabilitation considered Mr Y to be in a
vegetative state without prospect of improvement. Mrs Y and
their children believed that he would not wish to be
kept alive given the doctors’ views about his
prognosis. The
clinical team and the family agreed that it would be
in Mr Y’s best interests for CANH to be withdrawn,
which would result in his death within two to three
weeks.’
‘On 1 November
2017, the NHS Trust sought a declaration in the High
Court that it was not mandatory to seek the court’s
approval for the withdrawal of CANH from a patient
with PDOC when the clinical team and the patient’s
family agreed that it was not in the patient’s best
interests to continue treatment and that no civil or
criminal liability would result if CANH were
withdrawn.’
‘The High Court
granted a declaration that it was not mandatory to
seek court approval for withdrawal of CANH from Mr Y
where the clinical team and Mr Y’s family were in
agreement that continued treatment was not in his best
interests. The
judge granted permission to appeal directly to the
Supreme Court. In the intervening period Mr Y died but
the Supreme Court determined that the appeal should go
ahead because of the general importance of the issues
raised by the case.’
‘The Supreme Court
unanimously dismisses the appeal. Lady Black gives the
sole judgment with which the other Justices agree.’
Backdoor euthanasia in UK
The
British Medical Association (BMA) is studying whether
doctors should be allowed to ‘pull the plug’ on patients
with severe dementia or other degenerative diseases. Confidential
draft guidelines, detailed in a 77-page document, have
been circulated after the recent Supreme Court ruling
that NHS staff and officials no longer need a court's
permission to withdraw CANH (clinically-assisted
nutrition and hydration) from a patient who is
incapacitated and unable to speak or feed themselves,
but who are not imminently dying.
Furthermore,
the BMA is suggesting that doctors should be able to end
the lives not only of patients in vegetative or
minimally conscious states (VS or MCS), but also of
those with common degenerative conditions, like advanced
dementia, provided that it is in the patient’s best
interest. Other
patients who could have CANH withdrawn would include
stroke patients and patients with ‘rapidly progressing
brain injury’. The
proposed guidelines would include, ‘… those
patients who have a recognised degenerative condition –
such as advanced dementia, Parkinson's or Huntington's
disease – that is likely to result in the patient being
unable to take sufficient nutrition orally.’ The consultation
also states, ‘Due to the degenerative nature of their
condition, these patients are on an expected downward
trajectory and will inevitably die, usually as a result
of their underlying condition, although perhaps not
imminently and could, potentially, go on living for many
years.’
This
smells like euthanasia by the backdoor. UK parliaments
have consistently refused to legalise euthanasia or
assisted suicide for people with such conditions. But now the
BMA is considering that ending these lives by starvation
and dehydration, rather than blatantly with a lethal
injection or by drinking poison, is perfectly
acceptable. How
is this different from up-front euthanasia? It is thought
that these guidelines will not be open for public
consultation before their publication in the autumn. If you can’t
feed yourself, you could be in real trouble.
The case of Niall McGrath
In March 1989,
Niall McGrath incurred massive brain injuries as he
allegedly fell down steps in a London pub. Six
operations and ten days later, a week before his 21st
birthday, doctors pronounced him ‘clinically dead’. Sandy, his
sister, said, ‘They actually withdrew him off
life-support three times. He was a
write-off.’ But
instead of rapidly wasting away, Niall began to
breathe. He
was moved to the National Rehabilitation Centre in Dun
Laoghaire and later to St Joseph’s Care Home in
Longford, Ireland, where he has remained ever since.
Up until 8 years ago, Niall could not speak or
move. Then
in 2010 he stunned doctors when he came out of his
coma. He
has since been steadily recovering. Now the
50-year-old is making massive strides. He is able
to stand up for 25 minutes and he can transfer himself
from the wheelchair to the bed. He also uses
an iPad, and attends speech therapy. His sister calls on him every
lunchtime and brings Niall’s 73-year-old mother, Mary,
to visit him every evening. Sandy is
concerned that people like Niall could die under
legislation passed by the UK’s Supreme Court in July
allowing medical teams and families to withdraw life
support without applying to the courts. She fears
similar laws may be introduced into Ireland.
Euthanasia numbers from Belgium
Every
two years the Belgium Federal Commission on the
Control and Evaluation of Euthanasia presents a report
detailing statistics and developments in the practice
of euthanasia in Belgium. Here are
some of the latest data, which relate mostly to a
12-month period between 2016 and 2017.
Deaths by legal
euthanasia have increased nearly tenfold (982%) from
235 in 2003 – the first full year of legalisation – to
2,309 in 2017. From
2016 to 2017 alone the increase was 13.8%. Officially
reported euthanasia accounted for 2.1% of all
deaths in Belgium during 2017. Organ donation
couples with euthanasia (ODE) was reported in 8 patients
– the majority of them were female, Dutch speakers, aged
50 to 69 and with their deaths imminently expected.
There
were 375 cases of reported euthanasia of people whose
deaths were not expected in the near future. They
represented 16.2% of all cases of reported euthanasia. There were 181
cases of reported euthanasia for ‘polypathology’, where
two or more conditions exist, but none of which is a
sufficient ground for euthanasia – this
represents a 69.1% increase in just two years from 2015. In 27 (7.2%)
of these cases the mandatory one-month waiting period
between the written request for euthanasia and its
execution was not complied with, yet the Commission took
no action on these cases other than sending the
offending physician ‘a didactic letter to remind the
doctor of the procedure to be followed in cases of
unexpected death in the short term.’ A further 87
cases involved no physical suffering at all. This included
14 people with cancer, 15 with physical illness, 18 of
‘polypathology’ and 40 of mental ill health. There were
also 3 children killed between 2016 and 2017. These were a
17-year-old child, who was suffering from muscular
dystrophy; a 9-year-old child, who had a brain tumour,
and an 11-year-old child with cystic fibrosis.
What
to conclude? There
is no doubt that euthanasia practice in Belgium is
continuing on a dicey pathway of normalising the
practice. It
has been 16 years of slippery slope. It is
becoming the go-to response to an ever-increasing
range of circumstances, medical, physical and
psychiatric, and including children. Moreover,
there is good evidence that the law is being
repeatedly flouted and the authorities are turning a
blind eye.
AAFP goes ‘neutral'
In
early October, the American Academy of Family Physicians
(AAFP), one of largest medical associations in the US,
with over 131,000 members who specialise in family
medicine, dropped its long-standing opposition to
euthanasia. Instead,
it voted at the Academy’s 2018 Congress of Delegates in
New Orleans to adopt a position of ‘engaged neutrality
toward medical aid in dying as a personal end-of-life
decision in the context of the physician-patient
relationship.’ Whatever
does that mean? Over
two-thirds of delegates voted to change the position. Several
representatives gave emotionally-charged speeches about
how the availability of euthanasia could help ease the
suffering of patients.
The
new resolution passed by the delegates also calls on the
AAFP to reject use of the phrases ‘assisted suicide’ or
‘physician-assisted suicide’ in its own formal
communications and instead use the term ‘medical aid in
dying’. This
is reminiscent of the term ‘medical assistance in dying’
(MAID) favoured in euthanasia-ridden Canada. While some
delegates were very disappointed by the decision, their
consolation is that the AAFP did not endorse euthanasia,
at least, not for the moment.
But
is ‘neutrality’ a viable stance? The American
Medical Association (AMA), an umbrella organisation, of
which the AAFP is one of dozens of medical associations,
opposes ‘aid in dying’.
Its
official position is that, ‘Physician-assisted
suicide is fundamentally incompatible with the
physician’s role as healer, would be difficult or
impossible to control, and would pose serious societal
risks.’ Must
the AAFP now quit the AMA?
Canada slips down the slope
Euthanasia
enthusiasts are never satisfied. Once they get
the practice onto the Statute Book they always want to
widen and deepen the eligibility criteria. And so it has
come to pass in Canada.
In 2015, the Supreme Court of Canada decided to
decriminalise medical assistance in dying for patients
who are experiencing ‘grievous and irremediable’
suffering. The next year, the Canadian government
passed legislation that permits doctors to hasten the
death of a patient. So why not couple one wish
with another and combine euthanasia with organ donation?
This
would be ‘a good thing’ according to an opinion piece by
Ball, Sibbald and Truog in the New England Journal
of Medicine (2018) 379: 909-911
and entitled, ‘Voluntary Euthanasia –
Implications for Organ Donation.’ These two
physicians and a bioethicist state that, ‘Canada now
permits physicians to hasten the death of a patient by
means of physician-assisted suicide or voluntary
euthanasia.’ And
they go further, ‘This development creates a new pathway
for organ donation.’
They
believe that euthanasia offers significant advantages
for organ transplant surgeons. The normal
organ donation protocol is to wait for a couple of
minutes after blood circulation ceases in the dead
donor. But
even in that brief space of time the quality of the
organs declines. If
they were removed in a coordinated operation from a
euthanasia patient, they would be as fresh as possible. This macabre
scenario is already practised in Belgium and the
Netherlands as organ donation euthanasia (ODE). The current
authors recognise that the Canadian medical system would
first need to be tweaked – ICU staff
would need training to keep people alive. They would
actually have to kill patients for their organs. And
conscientious objectors could pose an obstacle. But hey, who
cares about such niceties?
The entrée consists of a happy death and nice
warm organs. Who
could possibly object?
Euthanasia in Australia
In
August, Australia’s
Senate voted down a Bill that would have
allowed the country’s two territories – the
Australian Capital Territory (ACT) and the Northern
Territory –
to legalise euthanasia.
The Senate narrowly rejected the Bill by 36 votes
to 34 after several days of debate. The Bill was
sponsored by an independent, Senator David Leyonhjelm,
and was widely supported by the Australian Labor Party
senators and senators from smaller parties. Most members of
the government, however, opposed the legislation.
If
successful, the Bill would have overturned the
Euthanasia Laws Act 1997, a law that removed the power
of the ACT and Northern Territory to legislate on
euthanasia. That
law was introduced in response to the Northern
Territory’s legalisation
of
euthanasia in 1995, but which was repealed the
following year. This
latest development in the Australian euthanasia debate
is particularly significant, as euthanasia legislation
would likely have had strong support in both the ACT and
Northern Territory.
Euthanasia in Spain
Las
malas noticias! Last year, a
poll found that 84% of Spaniards supported euthanasia
for people with incurable conditions. Now
Spain has taken a step towards becoming the first Roman
Catholic country in southern Europe to legalise
euthanasia by passing a draft law giving its citizens
the right to die. There
is overwhelming support for decriminalising euthanasia
and the legislation could make it available through
public healthcare. The
Bill, proposed by the new Socialist administration, was
backed by the centre-right Citizen’s party, Podemos on
the far left, and regional parties from the Basque
Country and Catalonia. The
conservative Popular Party (PP) opposed the Bill but it
still passed by 208 votes to 133.
The
proposal will now be debated before it returns for a
final vote and could be law next year, making Spain the
seventh country to legalise ending life. The draft law
stipulates that a person can choose to die if they have
a serious and terminal illness, or a chronic and severe
disability. They
must be Spanish or legally resident, meaning that
British expatriates might also be eligible. A request to
die must be made in writing, without pressure, and
repeated after 15 days.
Adriana Lastra, a
Socialist MP, said that her party had modelled the
Bill on legislation in Holland, Belgium and
Luxembourg. She
said, ‘We present this law with respect for
dignity [and] liberty and respect for people whose only
possibility is to suffer; we want to put an end to this
hell. It is
their last desire, their last right, their last freedom:
to die well. Pilar
Cortés, a PP MP, responded, ‘To talk about euthanasia is
to talk about failure, to admit a political,
professional and medical defeat.’
USA and
Elsewhere
Brett Michael Kavanaugh
So
Donald Trump’s controversial nominee finally got his
seat on the SCOTUS, the Supreme Court of the United
States. Justice
Kavanaugh is a 53-year-old Roman Catholic, who is
married to Ashley with whom he has two daughters. On the evening
of 6 October, he was sworn in at a private ceremony
after weeks of acrimonious debate. The Senate had
earlier backed his nomination by 50 votes to 48. All this
followed four days of questioning by the Senate
Judiciary Committee, a bitter battle over claims of
sexual assault (which he vigorously denied), an
additional investigation by the FBI, several excoriating
articles in the media, and numerous protest marches by
feminists and others.
Why
all the bluster? First,
there were the assault claims that reached back to the
1980s. Second,
there was Mr Kavanaugh's record of previous legal
opinions – he is considered to be conservative and
therefore, because he is replacing the liberal Justice
Anthony Kennedy, he will likely tilt the balance of the
SCOTUS to 5 vs. 4 in opposition to issues like abortion
and same-sex ‘marriage’. Many
consider that the colossus of Roe vs. Wade could now be
under threat. His
appointment is for life and the US pro-life constituency
is generally delighted, maybe even thrilled.
Donald Trump on evangelicals
In
late August, a dinner was held at the White House
attended by leading evangelical Christians. Donald Trump
recognised the support he had received from them to
secure the presidency, ‘But I really don't feel guilty
because I have given you a lot back, just about
everything I promised.’
He pointed to moves by his administration to stem
the flow of federal funding to abortion clinics and his
work to secure the freedom of imprisoned church leaders
around the world.
Mr
Trump welcomed several high-profile Christian figures
for the formal occasion, including Rev Franklin Graham,
the president of the Christian university Liberty, Jerry
Falwell Jr. and James Dobson from Focus on the Family. The US
President also said that ‘attacks’ on faith communities
throughout the US were ‘over’, citing his efforts to
protect freedom of conscience and religious liberty. He added,
‘Unlike some before us, we are protecting your religious
liberty. We're
standing for religious believers, because we know that
faith and family, not government and bureaucracy, are
the centre of American life. And we know
that freedom is a gift from our Creator.’
It is now said
that there are more evangelical Christians in the
Trump government than ever before. And there
are Bible studies in the White House, and there is
more prayer in that building than since America’s
early history.
Chelsea Clinton on abortion
The daughter of
former US President Bill Clinton was interviewed by
the satellite radio station, SiriusXM, in September. She
suggested that it would go against Christian values
for the United States to revert to a time before Roe
vs. Wade. She
talked about her efforts to keep abortion legal in the
US and said, ‘Every day I make the moral choice to be
optimistic that my efforts and my energies,
particularly when I'm fortunate enough to be in
partnership with fellow travellers, hopefully will
make a difference.’
Asked about a possible repeal of Roe vs. Wade,
she replied, ‘That's unconscionable to me, and also,
I'm sure that this will unleash another wave of hate
in my direction, but as a deeply religious person,
it's also unchristian to me.’ OK, her
views are ditzy, but she does have political ambitions
and so her views are noteworthy (and worrying).
Foetal
parts for sale
In
July, the US Food and Drug Administration (FDA) had
awarded a one-year contract to spend taxpayer’s money to
buy aborted foetal parts for experiments to breed
‘humanized mice’ in order to evaluate the safety and
efficacy of various drugs.
Advanced Bioscience Resources Inc. (ABR), a
California-based company, would supply ‘fresh’ and
‘human fetal tissue’.
According to ABR such tissue is obtained from
first or second trimester abortions, as well as
full-term stillbirths.
ABR has previously admitted to Congress that it
obtained tissue by collecting human foetal remains from
abortion clinics, paying $60 per ‘single aborted fetus’
and then upselling the unborn child’s body parts
separately to researchers for $325 per ‘specimen’ –
brain, eyes, liver, thymus and lungs.
The
pro-life lobby was outraged. Marjorie
Dannenfelser, president of the pro-life Susan B. Anthony
List group, said, ‘Under no circumstances should the US
government be contracting with baby-parts dealers like
ABR – who have partnered with abortion giant Planned
Parenthood – or taxpayers be forced to fund such
atrocities. We
call on Congress to … stop taxpayer funding of these
repugnant practices and act swiftly to ban them
altogether.’
Meanwhile, the US
Department of Health and Human Services (HHS), which
oversees the FDA, had been reviewing ‘all research
involving fetal tissue’ and ‘all acquisitions
involving human fetal tissue.’ On 24
September, it cancelled this $15,900 contract with
ABR. According
to the HHS it ‘was not sufficiently assured that the
contract included the appropriate protections
applicable to fetal tissue research or met all other
procurement requirements.’ The
government’s action comes after 85 members of the US
House of Representatives sent a letter to the FDA on
17 September, saying that the
purchasing of aborted fetal tissue for use in
research is ‘abhorrent’ and must stop, and claiming
that ABR might have violated federal law by selling
‘the body parts of children’ for a profit.
Some
think that the Trump administration will introduce a
ban or heavy restrictions on federally-funded
experiments with fetal tissues. Others think
that if you’re going to throw away the aborted tissue
anyway, can you not at least donate it to important
medical research?
The world and euthanasia
During
the first week of October, the World Medical Association
(WMA) held its annual medical ethics conference and
annual general meeting in Reykjavik. Euthanasia was
on the agenda. The
pro-euthanasia Canadian Medical Association (CMA) and
the Dutch Medical Association (KNMG) prepared a
resolution in a bid to change the position of the WMA’s
opposition to euthanasia.
In the event, it was withdrawn because of lack of
support.
Meanwhile,
the August edition of the WMA's World Medical
Journal
contained reports from doctors around the world who had
debated end-of-life care issues. In Brazil, WMA
members declared that, ‘if the doctor is prepared not
only to cure but also to kill, the ethics of medical
practice and the trust that the patient must have in his
doctor will be very battered.’ Furthermore, all
of the medical associations in Israel, Australia, New
Zealand, Japan and China were opposed to euthanasia. Similarly, those
in Africa, were ‘unanimously opposed to euthanasia and
physician-assisted suicide in any form.’ At one of the
symposia of the WMA conference, the majority of
participants rejected euthanasia ‘as being diametrically
opposed to the ethical principles of medicine and
expressed concern that they could lead to misuse or
abuse.’
Abortion in South Korea
Abortion
is illegal in South Korea except for cases of rape,
incest, genetic disorders, or where the pregnancy would
threaten a woman’s health.
Yet it is also commonplace with about 340,000
technically-illegal terminations performed annually. In August, the
government issued regulations that threatened to ban
doctors from practice for a month if they were found to
have performed an illegal abortion. The new rules
have included abortion among a list of ‘immoral medical
actions’.
In
September, almost two thousand South Korean obstetrics
and gynaecology doctors protested against these new
Ministry of Health and Welfare abortion regulations by
refusing to perform abortions for women. The Korean
College of Obstetrics & Gynecologists issued a
statement, ‘We flatly refuse to carry out abortions,
which the government has defined as an immoral medical
action.’ Lee
Young-Kyu, vice-chairman of the Korean College of
Obstetrics & Gynecologists, said that the ban was
‘simply appalling’. ‘Patients,
who seek abortions, were often poor or underage’, she
said, adding that, ‘If women were forced to give birth
in these circumstances, it puts a question mark on
whether that is moral.’
Meanwhile, the country’s Constitutional Court is
reviewing the near total ban on abortion, and is
expected to make a ruling later this year.
Abortion in Argentina
Currently abortion in Argentina is allowed only
in cases of rape, or if the mother's health is in
danger. In
August, Argentina’s
Senate rejected a Bill, which would have legalised
abortion in the first 14 weeks of pregnancy, by 38
votes to 31. After
a marathon session that lasted 17 hours, senators
voted against the Bill that had already been narrowly
approved by the Lower House. Argentine
president Mauricio Macri confirmed that he would have
signed the Bill if it was approved by the Senate,
despite his personal misgivings.
Pro-life activists were jubilant at the
outcome. One
said, ‘It's a joy to see that our society can be based
on such an important principle as the defence of the
most defenceless, the child.’ Camila Duro, from
the pro-life organisation, Frente Joven, said, ‘The
message that we wanted to put across is that abortion
equals social failure. For
a woman to resort to it, many other things need to
have failed first.’
‘Abortion always kills a child and it doesn't
solve the woman's problem. We believe
that this is never the solution. Faced with an
unexpected pregnancy abortion is never the solution. There are
always other solutions,’ said pro-life campaigner, Maria Castillo. Nevertheless,
pro-choice campaigners say they are not
giving up. Some
started fires and lobbed missiles at police after the
vote.
IVF boost in China
China
is in trouble. The
most populous country in the world is on a pathway to
demographic disaster.
The population is aging and there are not enough
babies being born to ensure a stable society. By 2050, it is
estimated that China will have 487 million people who
are 60 or older, while the labour force will have shrunk
to 424 million – last year it was 776 million. The National
Health and Family Planning Commission, China’s top
health authority, is therefore considering a change in
the law to encourage more women to have children.
For
example, it may allow single women to access IVF
programmes. At
present, any woman seeking fertility treatments in China
must first produce a marriage licence, so single women
have no choice but to go abroad to freeze their eggs or
have IVF or sperm donation. Li Jun, a
Shanghai-based lawyer, has objected, ‘When you demand a
woman to get married before she can have a child, that’s
curbing one’s human rights.’ It is clear
that Chinese women are choosing career over children. So, for
example, Ctrip, China’s largest travel agency, is
offering its female employees, those in middle to senior
management roles, from 100,000 yuan to 2 million yuan
(£11,000 to £230,000) to spend on freezing their
ova. It is a scheme that Ctrip executives hope
will enable women to stay in employment and to postpone
having children for a little longer. While it may
be in the spirit of the government’s drive, it also has
a practical advantage for the company.
In
2016, China loosened its notorious one-child policy,
but, so far, there have been too few couples prepared to
have extra children to make any real difference – the
one-child family appears to have become a stubborn
societal norm.
Miscellaneous
A shorter story
One
of my favourite quotations is that attributed to Blaise
Pascal, ‘Je n'ai fait celle-ci plus longue que parce que
je n'ai pas eu le loisir de la faire plus courte.’
It translates as, ‘I would have written a shorter letter, but I did
not have the time.’
It is recorded as number 16 of his ‘Provincial
Letters’ written by Pascal to a group of Jesuits on 4
December 1656 protesting about the practical morals of
the Roman Catholic Church.
Then
again, I have heard [far too many] sermons that could
have been cut, even slashed, without detriment. Moreover,
every piece of writing can be improved by editing,
despite the usual protestations of prolix authors. More’s the
pity that a growing number of publishers no longer
employ copy editors with their blue pens and scissors. And by editing
is invariably meant shortening. So, how about
not just shortening an article, but going for the
ultimate and creating an entire story in just a few,
say, six words? In
the truncated world of Twitter that ought to be simple.
But
can this fabled example, often ascribed to Ernest
Hemingway, which he produced allegedly to win a bet, be
improved upon? Here
it is: For sale, Baby shoes, Never worn.
Beat that!
See, there is already a story going through
your head, perhaps even the rough outline of a film. And does
it have a definite bioethical theme? It does
for me.
Are you fat and
lonely?
Thankfully,
currently,
I am neither, but I know people who are. About
62% of adults in the UK are now classified as
overweight, while 28% are clinically obese.
Obesity is one of the leading preventable cause of
death. It is often associated with additional
conditions, like diabetes mellitus, heart disease and
stroke. The NHS is already creaking with the
obesity overload. Most of its victims simply eat
too much, especially the wrong types of food, and they
typically lack sufficient physical activity.
Similarly,
loneliness is on the increase. Over 9 million
people in the UK – almost a fifth of the population –
say they are always or often lonely. At least half
(51%) of all people aged 75 and over live alone. Two fifths of
all older people, almost 4 million in total, say the
television is their main company. Prime
minister, Theresa May, has recently announced a range of
activities that GPs can refer their lonely patients to,
as a means of tackling this epidemic. These will
include social activities, such as cookery classes,
walking clubs and art groups.
Both
obesity and loneliness are sad and dangerous markers of
our so-called advanced Western society. We can all
think of simple reasons why some are fat, or lonely, or
both. But
is there a genetic reason?
Do genes predispose some people to these
conditions? It
might seem a theory a tad farfetched, but it has been
the subject of a recent study published in Nature
Communications (2018, 9: 2457) by
Day et al.,
from the University of Cambridge School of Clinical
Medicine, under the title, ‘Elucidating the genetic
basis of social interaction and isolation.’ They kindly
reframe fat and lonely as ‘adiposity’ and ‘social
isolation’.
The researchers performed genome-wide association study analyses for loneliness and regular participation in social activities in 452,302 UK Biobank study participants. They identified 15 genomic loci for loneliness, and demonstrated a likely causal association between adiposity and increased susceptibility to loneliness and depressive symptoms. Fascinatingly, further loci were identified for regular attendance at three places – a sports club or gym, pub or social club, or religious group. They found, ‘Across these traits there was strong enrichment for genes expressed in brain regions that control emotional expression and behaviour.’
And
furthermore, ‘These data highlight shared genetic
architecture between loneliness and a range of complex
traits, including a causal relationship between body
size and loneliness/depressive symptoms.’ In other
words, some people are genetically prone to an
association between ‘adiposity’ and ‘social isolation’, but only a
little, just 4.2%, so don’t blame your genes
for your troubles. And
the remedial prescription? Eat less,
walk more, and go to church would be a good start for
many.
What is full and valid consent?
Depending
on the context, consent to treatment can be varied. When I go to
the doctors’ surgery with my painful, swollen ankle and
she says, ‘May I have a look? It would be
churlish of me to refuse.
Typically, taking off my sock is deemed to be my
consent. Moreover,
‘a look’ is customary code for, ‘May I touch, prod and
gently twist it?’ There
is no discussion, no paperwork, no signature involved. On the other
hand, when I go to hospital to have surgery on that
ankle, there is discussion, paperwork and signature.
Doctors
are supposed to treat patients with respect, which
implies engaging with them, giving them enough time and
encouragement to ask questions, such as, ’What if I do
not undergo this operation?, what are the side-effects
of this medicine?, is there another, better option?, and
so on. Getting answers to these sorts of questions
undergirds what that man on the Clapham omnibus would
consider to be the best route to full, valid and
informed consent.
In
the UK, until recently, such consent was based on the
Bolam test, namely, whether a reasonable body of medical
opinion would agree that a professional’s duty of care
had been fulfilled.
Then along came Nadine Montgomery. She gave birth
to a baby boy on 1 October 1999 at Bellshill Maternity
Hospital, Lanarkshire.
The birth was complicated by shoulder dystocia
that resulted in the child being born with cerebral
palsy. A
case of medical negligence was pursued as Montgomery vs.
Lanarkshire Health Board.
In those proceedings, Mrs Montgomery sought
damages on behalf of her son for the injuries which he
sustained. She
attributed those injuries to negligence on the part of
Dr Dina McLellan, a consultant obstetrician and
gynaecologist, who was responsible for Mrs Montgomery’s
care during her pregnancy, labour and delivery.
Eventually,
in 2015, the UK Supreme Court declared that the Bolam
test was an outdated instance of medical paternalism. The Montgomery
ruling established that doctors must ensure that their
patients are aware of any material risks involved in a
proposed treatment, and of reasonable alternatives.
This
is particularly relevant in cases of abortion. Is the women
presented with ‘reasonable alternatives’? Is she told
about the possibilities that the procedure may be linked
to the onset of breast cancer, physical and mental
health issues, fertility loss, and so on? These may be
controversial sequelae, but is the women entitled to
hear them before she gives her full and valid consent? After all, she
is about to decide to let a doctor take the life of her
unborn child. That
is no small decision.
So,
three years on, how is the Montgomery ruling working? The unadorned
answer from an article in the Lancet (2018,
392:
102-104) and entitled, ‘How Montgomery is reconfiguring
consent in the UK’ by Natalie Harrison and colleagues
from London, is ‘slow and patchy’. They carried
out semi-structured interviews with six obstetric
consultants and doctors and four barristers, all
practising in the UK.
They reported that, ‘The Montgomery ruling aimed
to guide the medical profession towards a new model of
shared decision making, however, doctors are still
working out what the ruling means in practice.’ The authors
provide a number of innovative attempts being
implemented here and there, but there seems to be little
professional assistance.
For example, only two of the 24 member colleges
of the Academy of Medical Royal Colleges (the Royal
College of Obstetricians and Gynaecologists and the
Royal College of Surgeons of England) have issued
detailed guidance in light of the ruling.
John Craig Venter
I
like to include a human-interest piece in these Updates on Life
Issues, whether as an obituary or as a
biographical piece.
It is not my fault that no-one worthy of a
valedictory article has died recently. Instead, let
us look at Craig Venter, the 72-year-old, variously
described as ‘one of the leading scientists of the 21st
century for his numerous invaluable contributions to
genomic research’, ‘a maverick American biologist’ and
‘not a man to balk at breaking a few eggs to make a
scientific omelette’.
From
1967 to 1968, John Craig Venter was on duty as a Navy
Corpsman in Vietnam.
He then earned a bachelor’s degree in
biochemistry and a PhD in physiology and pharmacology
from the University of California at San Diego. Next, he was
appointed professor at the State University of New York
at Buffalo and the Roswell Park Cancer Institute. After time
working at the US National Institutes of Health, he
founded The Institute for Genomic Research, where, in
1995, he and his team decoded the genome of the first
free-living organism, the bacterium Haemophilus
influenzae, using his novel whole genome shotgun
technique. In
1998, Venter founded Celera Genomics to sequence the
human genome.
He is
best known for challenging the scientific Establishment
in that race to decipher the human genome, a task
completed in 2000.
With his shotgun sequencing technique, he
achieved in two years what the official Human Genome
Project (HGP) had taken 14 years to complete. Since then he
has attempted to patent artificial microbes, to
reconstruct people’s faces from their DNA and to comb
mankind’s genetic library in search of the secret of
longevity. He
is the author of more than 280 research articles and two
books, including an autobiography (of course). Oh yes, he is
a real, scientific superstar.
Now
Craig Venter is embroiled in perhaps his biggest
wrangle. Human
Longevity, Inc. (HLI), is a company he set up with two
colleagues in 2013 to search the growing masses of
genetic data in the hope of generating treatments for
diseases associated with ageing – he believes he can
help people live to 100 and beyond. Last July, HLI
began suing his San Diego-based, non-profit
organisation, the J Craig Venter Institute, over
allegations that he stole its trade secrets, poached its
staff, and sought to lure away its investors. It takes a
special sort of man to generate that sort of
predicament.
A
spokeswoman for HLI said, that as yet, the company could
not offer any further clarification because that would
involve describing its ‘litigation strategy’. ‘We do not
comment on such matters while litigation is pending,’
she said. Meanwhile,
the J Craig Venter Institute dismissed the claims as,
‘baseless, without merit and [marred by] numerous
factual errors.’ And,
‘We intend to vigorously defend against these
allegations as the legal process advances.’ The document
lodged with the Southern District of California court
leaves space for an unspecified number of unknown
‘competitors of HLI’ to be added to the list of
defendants. The
courts and J Craig Venter could be busy for many months
to come.
A new Hippocratic Oath
It
was a combination of the Hippocratic Oath and the
Judeo-Christian doctrines that established the wholesome
ethics and practice of early Western medicine. With their
‘first, do no harm’ and ‘love your neighbour as
yourself’, they kept medicine safe and beneficial for
over 2,000 years. Sadly,
their influence has now declined. The
Hippocratic Oath has over the last 70 or so years
reappeared in various, but always in
bioethically-weakened, forms.
Here
is a snapshot of that downgrade. The original
Hippocratic Oath specifically forbade both euthanasia
and abortion, ‘I will give no deadly drug to any, though
it be asked of me, nor will I counsel such, and
especially I will not aid a woman to procure abortion.’ In 1947, the
British Medical Association (BMA) affirmed that the
Hippocratic Oath, '… enjoins … the duty of caring, the
greatest crime being co-operation in the destruction of
life by murder, suicide and abortion.' By 1997, that
same BMA had produced its draft revision of the
Hippocratic Oath, which stated, ‘I recognize the special
value of human life but I also know that the
prolongation of human life is not the only aim of health
care. Where
abortion is permitted, I agree that it should take place
only within an ethical and legal framework.’ Similarly, in
2005, the World Medical Association approved a revision
of the Declaration of Geneva, which modestly asserted,
'I will maintain the utmost respect for human life; I
will not use my medical knowledge contrary to the laws
of humanity, even under threat.’ The removal of
that vital phrase ‘from the time of conception’ not only
eliminated the implicit anti-abortion stance of the
original, but it also simultaneously introduced doubt
about the fundamental
issue of when human life begins.
The
University of Exeter Medical School was set up in 2012. Its first-year
students began the new programme in September 2013. This summer,
its first cohort of medical students graduated. Interestingly,
they devised their own version of the ancient Greek
oath, which the 88 doctors-to-be swore at their July
graduation ceremony.
It emphasised their commitment to service and
care, advancing knowledge and life-long learning and
teaching, and to maintaining their own health and
well-being.
Amidst some of the somewhat florid language and
politically-correct platitudes there was this welcome
sentence, ‘I shall never intentionally cause overall
harm to my patients, and will have the utmost respect
for human life.’
While this echoes the grand Hippocratic
statement, an echo is never as strong as the original
chime –
it can be almost inaudible. And the
Exeter Oath also included, ‘I will work towards
a fairer distribution of health resources and oppose
policies in breach of human rights.’ One can only wonder
if the Exeter doctors had ever pondered the 1948
General Assembly of the United Nations adoption of the
Universal Declaration of Human Rights, of which
Article 3 declares, 'Everyone had the right to life …' Let us hope
that these new doctors take seriously their pledge, ‘I
will seek to
increase my understanding and skills, and promote the
advancement of medicine as both a teacher and a
learner.’ May
they read a good bioethics book!
Learn a new word
Tokophobia.
No, it’s not a fear of clocks – that is
chronomentrophobia. Tokophobia is a pathological
fear of childbirth from the Greek tokos,
meaning childbirth and phobos, meaning
fear. And it is apparently on the increase,
according to Catriona Jones, a lecturer in midwifery
at the University of Hull. So much so, that NHS
perinatal mental health services have asked her to
look into the problem after a recent and notable rise
in the number of women asking for caesarean
sections. For some women tokophobia can be so
severe that they never become pregnant or, if they do,
they may decide to abort. What such women need
is a pathway of proper support and care, which should
be available from mental health practitioners,
midwives and health visitors. Or they could
spend time with a pro-life counsellor.
