The general election
A word in season. You may have a pro-life MP –
good for you. Or you may not – join the
club. Whichever, this is an opportune time to
meet them and ask them some pointed bioethical
questions. Now, you know that I would not ask
you to do something I’m not prepared to do. So,
my wife and I visited our MP last month. We
questioned him particularly about his views on
abortion and assisted suicide – he was polite, but
fairly non-committal.
Our meeting lasted a good 30 minutes. There were
several questions we forgot to ask him. What is
the basis of his moral framework? Does he have
any church involvement? When does he think human
life begins? Has he had recent representations
from others of a pro-life persuasion? And so
on. These are for another time.
But we are now better prepared to quiz those
canvassers whenever they ring our doorbell. Go
for it.
Abortion statistics for 2022
Here at last are the long-overdue numbers for 2022,
released at 09.30 on Thursday 23 May 2024. The
relevant information may be viewed here (cut and paste
if necessary):
https://www.gov.uk/government/statistics/abortion-statistics-for-england-and-wales-2022/abortion-statistics-england-and-wales-2022
As ever, there is no comfort in these cold,
unemotional statistics. The total number of
abortions performed on residents of England and Wales
during 2022 was 251,377. It is the first time
that the quarter of a million barrier has been
breached. It is an increase of 17% over the
previous year. It is an average of 967 each
weekday. It is less than the genuine total
because it takes no account of abortions caused by the
mifepristone-misoprostol pill combination, or those
completed by the morning-after pill.
How do you describe such numbers?
Scandalous? National scandals and their
associated Public Inquiries are becoming part of our
lives. There have been Hillsborough, infected
blood, Covid-19, Post Office and many more
scandals. And now this abortion scandal.
Sadly, the latter will not be the subject of a Public
Inquiry.
Here are some key data to sketch out this abortion
scandal. In 2022, 99% of these abortions were
funded by the NHS, with 80% of them subcontracted to
the independent abortion-provider sector. In
other words, they were taxpayer funded. And 86%
were medically induced with pills, as opposed to
performed surgically.
The vast majority (98%, 247,440) were performed under
ground C, the so-called ‘social clause’ for reasons
far and wide. There were 3,124 abortions
performed under ground E, the 'handicap clause’ and
545 of these were at 22 weeks and later.
Overall, most (88%) abortions were performed at under
10 weeks. There were 1,952 performed at 22 weeks
and over, with 260 at over 24 weeks – above the legal
limit.
Of all the women having abortions in 2022, 41% had
already undergone one or more previous
abortions. This repeat rate has increased from
37% in 2012. There were 72 selective
terminations, where more than one embryo has
inconveniently implanted, usually as a result of
overzealous IVF transfers.
Besides the 251,377 abortions for residents of England
and Wales, there were 745 for non-residents, plus 172
for residents of Northern Ireland and 16,584 from
Scotland. In other words, the total number of
officially recorded abortions occurring throughout the
United Kingdom during 2022 was 268,878. Each one
is now a lifeless child alongside a childless
mother. How do you regard that? Are you
horrified, troubled, or complacent?
Abortion at Westminster
On Wednesday 22 May, the prime minister made a
surprise announcement that the date for the next
general election would be Thursday 4 July. This
means that many pieces of pending Government
legislation were lost, including the Criminal Justice
Bill. This had become a ‘Christmas tree’ bill
with all sorts of miscellaneous attached tinsel that
disguised its main and important purposes. Among
the inappropriate hangings were two amendments
concerning the decriminalisation of abortion.
Two MPs with extreme views on abortion, namely Diana
Johnson and Stella Creasy, had tabled amendments to
this upcoming Criminal Justice Bill. These would
allow abortion for any reason, up to 40 weeks, with no
legal sanctions. Abortion would become merely a
woman’s health issue. Such amendments to
abortion law are far too serious to be merged into
this catch-all Bill.
The pro-life lobby was nervous. Would the
Speaker of the House select one, both or neither of
these amendments from among the 140 or so others that
had been proposed? Whichever, the all-important
Report stage of the Bill was scheduled for Wednesday
15 May. It was then rumoured to be the next day,
then the next week. Eventually Parliament was
prorogued on Friday 24 May and dissolved on Thursday
30 May. So, thankfully, the decriminalisation
attempts were lost. Hooray! But they will
be back, probably in the next Parliament.
Besides the miserable decriminalisation issues there
were two jolly pro-life amendments. First, there
was a Bill promoted by Caroline Ansell MP that would
reduce the current upper time limit for abortions from
24 to 22 weeks. This is in line with advances in
the neonatal care of newborns, who are now not only
regularly born, but also survive, at this age.
Second, Liam Fox MP had tabled his Down’s Syndrome
Bill, which would lower those ghastly abortions up to
40 weeks for the disabled to 24 weeks, the same upper
limit as most other abortions. Specifically, it
would eliminate the apartheid that labels the disabled
as second-class citizens with lives that are not
worthy to be lived. This Bill had at least 55
sponsors. But it too was lost in the so-called
‘wash-up’ at the end of this Parliamentary session.
IVF and ARTs
The
global IVF market
Vision Research Reports is a worldwide market research
and consulting organisation based in Ottawa,
Canada. According to its recent Report entitled,
‘In Vitro Fertilization Market Size & Trends’, the
global IVF market was valued at USD 25.3 billion in
2023 and is expected to grow at a compound annual
growth rate (CAGR) of 5.54% from 2024 to 2030.
In other words, IVF is hugely widespread and hugely
profitable.
The Report is primarily concerned with financial
aspects of IVF. However, it also includes an
astute summary of several bioethical aspects that
underlie the reasons for the projected growth in
global IVF. If you wish to understand IVF, here,
verbatim, are five market trends identified by this
Report:
1] Rising Demand for Genetic Testing: Increased
awareness and acceptance of genetic testing
techniques, such as comprehensive chromosomal
screening (CCS) and preimplantation genetic diagnosis
(PGD), are driving demand for IVF procedures with a
focus on selecting genetically healthy embryos.
2] Expansion of LGBTQ+ Family Building: The
LGBTQ+ community’s growing interest in family building
through assisted reproductive technologies, including
IVF and surrogacy, is fuelling market growth and
prompting clinics to offer inclusive services tailored
to diverse family structures.
3] Emergence of Low-Cost IVF Clinics: The
proliferation of low-cost IVF clinics and alternative
pricing models is making IVF more accessible to a
broader segment of the population, driving competition
and potentially reducing treatment costs.
4] Telemedicine and Remote Monitoring: The
integration of telemedicine platforms and remote
monitoring technologies into IVF services allows for
greater convenience, flexibility, and patient
engagement throughout the treatment process,
particularly in light of the COVID-19 pandemic.
5] Focus on Patient-Centric Care: IVF clinics
are increasingly prioritizing patient experience and
satisfaction by offering personalized treatment plans,
comprehensive support services, and transparent
communication to ensure a positive journey through
fertility treatment.
In addition to these market trends, the Report
identifies five market drivers of IVF:
1] Increasing Prevalence of Infertility: The
rising prevalence of infertility due to factors such
as advanced maternal age, lifestyle changes, and
medical conditions contributes to the growing demand
for IVF services. As more couples experience
difficulties conceiving naturally, they turn to
assisted reproductive technologies like IVF as a
solution.
2] Advancements in Technology: Ongoing
advancements in IVF technology, including improvements
in embryo culture techniques, cryopreservation
methods, and genetic screening technologies, enhance
the success rates and safety of IVF procedures.
These technological innovations attract patients
seeking more effective and personalized fertility
treatments.
3] Growing Awareness and Acceptance: Increased
awareness and acceptance of IVF as a viable option for
achieving pregnancy contribute to market
expansion. Education initiatives, media
coverage, and celebrity endorsements have helped
destigmatize infertility and promote IVF as a
mainstream reproductive option.
4] Demographic Trends: Changing demographic
trends, such as delayed childbearing and increasing
rates of same-sex couples and single individuals
seeking parenthood, drive demand for IVF
services. As individuals and couples postpone
childbearing for various reasons, they rely on IVF to
overcome age-related fertility challenges.
5] Rising Healthcare Expenditure: Increasing
healthcare expenditure and rising disposable incomes
enable more individuals and couples to afford IVF
treatments. Despite the high costs associated
with IVF, patients are willing to invest in fertility
services to fulfill their desire for parenthood,
driving market expansion.
The above insights come from an unexpected
source. They confirm that IVF, with all its
bioethical dilemmas, health dangers and costs, is here
to stay, even expand. However, the unceasing
bioethically-sound advice is, stay away from all
aspects of assisted reproductive technologies (ARTs),
including IVF.
Gamete donor compensation
In most parts of the UK, when someone donates their
ova or sperm at a fertility clinic, they receive
financial compensation. Currently, sperm donors
receive £35 per clinic visit and ova donors receive
£750 per cycle. These rates were last set in
2011 when the Human Fertilisation and Embryology
Authority (HFEA) felt that these compensation amounts
struck the right balance between covering donor
expenses and donors feeling valued, but not enough to
remove the altruistic motivations behind donating
gametes. They were regarded as reimbursement of
donor expenses rather than donor payment.
However, since 2011, inflation has taken its
toll. At its 20 March 2024 meeting, the HFEA
discussed donor compensation and decided to increase
the payments in line with cost-of-living inflation to
£45 for sperm donors and £985 for the more-medically
invasive ova donors based in the UK.
Patients receiving donor treatment may choose to use
gametes donated at a UK clinic, or they may choose to
import gametes donated abroad and imported into the
UK. In recent years the use of imported sperm
has increased. In 2011, imported donations
represented around 27% of new sperm donors. By
2021, 65% of new sperm donors were from
overseas. In 2020, donor imports from the USA
and Denmark accounted respectively for 27% and 21% of
new sperm donors registered in the UK. Donor ova
are less frequently imported, with only 4% of ova
imported in 2011, decreasing to 1% in 2021.
When considering overseas donations, it is clearly not
practicable to introduce individual compensation rates
for every country. Therefore, also at its 20
March 2024 meeting, the HFEA agreed to bring overseas
donor compensation rates in line with those of the UK.
The bioethically-disastrous Warnock Report (1984),
which has since governed thinking and practice in
human reproduction and embryo research, and which
prefaced the 1990 Human Fertilistion and Embryology
Act, recommended that IVF treatment should be
generally available, regardless of whose gametes were
involved, with no restriction on the supply, use, sale
or purchase of ova, sperm or embryos, with no
constraints on ova donation, and so on. In other
words, it approved the wholesale trading of human
gametes and embryos.
Forty years on, those recommendations should still
make us all uncomfortable. Is the trafficking
and marketing of gametes, those biological components
that make us individually unique, a wholesome and
praiseworthy activity?
Fertility clinics in trouble
IVF and most of the other assisted reproductive
technologies (ARTs) involve complex and potentially
dangerous procedures. They are prone to
failure. After all, IVF typically has a 70%
failure rate. In addition, sometimes human
errors arise. The main task of the Human
Fertilisation and Embryology Authority (HFEA) is to
devise the ART safety rules and ensure that all
practitioners abide by them.
One of the latest safety catastrophes came to light in
early March 2024 at the Homerton Fertility Centre in
East London. The HFEA suspended its operating
licence over what were described as ‘significant
concerns’. The Centre has admitted there had
been three separate incidents. They were ‘errors
in some freezing processes’, ‘a small number of
embryos’ had perished or were ‘undetectable’, meaning,
they could not be found after thawing.
The Centre has informed its clients and apologised for
the distress that the errors may have caused.
According to a BBC report, as many as 150 embryos,
belonging to up to 45 patients, could have been
destroyed or lost. The HFEA is now conducting
its own investigation alongside that of the
Centre. Interim measures now require all staff
to work in pairs to ensure all clinical activities are
checked by two healthcare professionals. In
addition, competencies of staff within the unit have
been rechecked, and security at the unit has been
increased.
In February 2024, another IVF disaster came to light
in the UK. A number of women were affected by
the use of a faulty freezing solution at fertility
clinics in London and Sheffield. The HFEA
confirmed that the only clinics affected were Guy’s
and St Thomas’ assisted conception unit in London and
Jessop Fertility in Sheffield. The clinics
attributed the incidents to a batch of faulty freezing
solution from CooperSurgical, a US-based
company. It was reported that frozen ova and
embryos may have been destroyed. Though it was
known in March 2023 that the freezing fluid had been
mislabelled, the women at risk were informed only in
February 2024. The London hospital has since
apologised to 136 women after their ova and embryos
were probably damaged during the freezing
process. The Sheffield hospital said it had
identified 29 people who had ova or embryos frozen in
August 2022, when the particular product batch was
used.
Rachel Cutting, the HFEA’s director of compliance and
information, speaking on behalf of the Authority,
stated that, ‘Fertility treatment in the UK is
generally very safe. Our most recent report
shows that out of the almost 100,000 treatment and
storage cycles which took place in 2022/23, more than
99% were conducted without any incidents
occurring.’ Yes, yes, yes. 1% may sound
pretty minor, but it is equivalent to as many as 1,000
incidents. Such occurrences can deeply trouble
women who have lost ova and embryos as well as their
prospects of pregnancy. Some were cancer
patients who have since undergone treatments, such as
chemotherapy or hysterectomies, and therefore missed
their opportunity to preserve their fertility.
Of course, such errors in IVF procedures are not
restricted to UK fertility clinics. The
burgeoning practice of IVF in the USA inevitably
includes adverse incidents. One recent example
has been reported in April 2024. Several couples
are now suing a southern Californian fertility centre
over claims that its staff destroyed their embryos in
a ‘toxic incubator’ yet subsequently transferred
deceased embryos to its patients. So far 11
couples have instituted legal proceedings against the
Ovation Fertility clinic at Newport Beach, California,
with more lawsuits expected.
The problem came to light when Ovation noticed a 0%
success rate among their IVF patients. For some
victims, this was their last chance to have a
biologically-related child. It is alleged that
the Ovation clinic staff mistakenly cleaned an
incubator containing the embryos of dozens of patients
with hydrogen peroxide instead of the usual sterile
solution. The use of peroxide killed the embryos
that nevertheless were transferred to the plaintiffs
between 18 January and 30 January 2024, none of whom
became pregnant.
According to Adam Wolf, attorney acting for some
victims, ‘My clients are devastated by Ovation’s
serious error. The only thing we can seek is
monetary compensation and accountability from
Ovation. We want to know what happened, how it
happened, and they want to make sure this never
happens again.’ All of the plaintiffs are
seeking a jury trial and are suing on several grounds
including negligence, medical battery and intentional
representation.
This example is a not unexpected calamity for the
largely unregulated IVF industry in the USA. It
is where those two great professions of law and
medicine conjoin. While the court battles
continue, the real losers in this war are the parents
of the hoped-for babies, and, of course, the embryos
themselves.
The bioethical mantra still stands – IVF is best
avoided.
Euthanasia and
Assisted Suicide
Jersey takes the wrong step
It has been a long and dreary road. Back in
November 2021, Jersey politicians approved ‘in
principle’ the legalisation of assisted dying on the
Island. The voting was 36 in favour, 10 against
and three absent. So Jersey’s Parliament became
the first in the British Isles to vote in favour of
legalising assisted suicide.
Public engagement and consultations, reviews and
dialogues, reports and publications followed.
During May 2024, the States Assembly met and debated
two Routes through which people, who have lived in
Jersey for longer than a year, are 18 or over and have
decision-making capacity, could apply for assisted
suicide.
On Wednesday 22 May, Assembly members voted to approve
plans to legalise assisted suicide for those with a
terminal illness ‘causing unbearable suffering’.
A total of 32 members voted in favour while 14 voted
against this so-called Route 1. Route 2, for
those who are not terminally ill but who have an
‘incurable physical medical condition causing
unbearable suffering’, was rejected by a majority of
27 to 19.
The vote on that Wednesday was significant, but it is
not the end of the road. States members have
merely given Deputy Tom Binet, Minister for Health and
Social Services, permission to proceed to draft new
legislation. It must still go through several
bureaucratic and legal approval hoops. It could
still be rejected.
As Tom Binet has stated, ‘The next step is the law
drafting [for Route 1], which will take up to 18
months. The draft law will then need to be
debated [and approved] by the Assembly [by the end of
2025], followed by an 18-month implementation period,
with the new law [if approved] coming into effect in
summer 2027.’
And now the Isle of Man
The legalisation of assisted suicide and euthanasia
for residents on the Isle of Man may have become a
step closer after crucial votes by its members of the
House of Keys (MHKs) during May 2024.
The Assisted Dying Bill, originally introduced by Dr
Alex Allinson, passed its second reading (17 to 7) in
October 2023. The Bill has since been debated in
its Clauses stage. On 7 and 14 May, two key
changes were approved. First, MHKs voted (14 to
10) to increase the required residency period on the
Island from one year to five, amid concerns that it
could encourage so-called ‘death tourism’.
Second, MHKs supported (15 to 9) a change to allow
those with less than a year to live, the right to die,
rather than six months as originally proposed.
The Clauses stage is likely to continue on 11
June. Afterwards, the Bill is expected to
receive a Third Reading in the House of Keys this
summer. If it passes this stage it will progress
onto the Legislative Council, the Upper House of the
Tynwald, for further debate and scrutiny. The
Bill could then receive Royal Assent as soon as next
year, followed by consideration of how the legislation
will be implemented. Assisted suicide deaths
could potentially become available for Manx residents
as soon as 2027. Thus, the Island could become
the first part of the British Isles to pass assisted
suicide legislation.
Both the Isle of Man and Jersey are crown dependencies
which set their own laws. However, approval of
assisted suicide in either jurisdiction could have
serious implications for the UK mainland.
And in Scotland
Or could Scotland become the first jurisdiction in the
United Kingdom to legalise assisted suicide? On
28 March 2024, Scottish Liberal Democrat, Liam
McArthur formally tabled in the Scottish Parliament
his private member’s measure, the Assisted Dying for
Terminally Ill Adults (Scotland) Bill. He said
that, ‘This Bill contains robust safeguards, similar
to those which have been safely and successfully
introduced in countries such as Australia, New Zealand
and the United States, where they continue to enjoy
strong public support.’
The Bill will now be scrutinised by the Health
Committee, before the so-called Stage 1 debate and
voting by MSPs, which is likely to occur later this
year. If approved, the Bill then progresses to
Stage 2, where MSPs can propose amendments. If
these are agreed, the amended version is considered at
Stage 3. This is the final debate and vote
before a Bill becomes law via Royal Assent.
Liam McArthur has stated that, ‘I’m confident
Parliament will back my proposals to give terminally
ill adults the choice they need.’ However, it is
far from certain that this third attempt in recent
years to legalise assisted dying at Holyrood will pass
on a conscience vote. The former First Minister,
Humza Yousaf, is opposed, along with the Church of
Scotland, the Catholic Church in Scotland, and the
Scottish Association of Mosques, plus thousands of
ordinary citizens.
Perhaps more surprisingly, the earlier First Minister,
Nicola Sturgeon, who is still very influential in
Holyrood and beyond, says that she is leaning towards
a No vote. In the Glasgow Times (3 April
2024), she wrote, ‘… the more deeply I think about the
different issues involved, the more I find myself
veering away from a vote in favour, not towards it.’
She continued with an excellent opposing testimonial,
‘I worry that even with the best of intentions and the
most carefully worded legislation, it will be
impossible to properly guarantee that no-one at the
end of their life will feel a degree of pressure, a
sense that it might be better for others for them not
be here – even if their loved ones try to persuade
them otherwise. And, even more, fundamentally, I
worry about the thin end of the wedge. That if
we normalise assisted dying – if we come to associate
dignity at the end of life with choosing to die,
rather than being supported to live in as much peace
and comfort as possible – then we will, as a society,
lose focus on the palliative and end-of-life care and
support that is necessary to help people, even in the
worst of circumstances, to live with dignity.
And I worry that, over time, this shift in collective
mindset will see the tightly drawn provisions of this
bill extended much further.’ Well said, wee
Nicola!
And in England and Wales
Assisted dying is still strictly illegal in England
and Wales. Successive UK Governments have so far
ruled out attempting to introduce any permissive
legislation. The last Westminster Bill, debated
in 2015, was defeated by 330 to 119. However, a
recent petition, organised by Dignity in Dying, called
on the Government to allocate Parliamentary time for
assisted dying to be fully debated in the House of
Commons and to give MPs a free vote on the
issue. Because it was signed by more than
100,000 people a debate was automatically
triggered. On 29 April that e-petition debate on
assisted dying took place in Westminster Hall.
Another Westminster grouping has also been busy
discussing the issue. Since December 2022, the
Health and Social Care Select Committee has been
convening the first-ever House of Commons inquiry into
assisted dying. The Committee, chaired by Steve
Brine MP, aimed to ‘gather the most up-to-date
information and views on the topic to inform
Parliament and the wider public.’ A cross-party
Committee of MPs has heard months of evidence, data
and personal accounts on assisted suicide. The
Committee received more than 68,000 responses from
members of the public and more than 380 pieces of
written evidence. On 29 February 2024, the
Committee published its Report.
The full Report, entitled, ‘Assisted Dying/ Assisted
Suicide Second Report of Session 2023–24’ is available
here:
https://committees.parliament.uk/publications/43582/documents/216484/default/
(cut and paste if necessary).
The Report has generally been well received as a
fair-minded response to a complex topic. It
calls on the Government to be ‘actively involved’ in
the assisted dying debate as reform becomes
‘increasingly likely’ across the British Isles.
Yet, perhaps wisely, to the relief of opponents and
dismay of supporters, the Report made no
recommendations concerning a change of law. It
stated, ‘Although select committees usually make
recommendations to Government, in respect of [assisted
dying] the Government has made it clear that it will
not take any steps towards legalising [it] but instead
that this would be Parliament’s role, should members
wish to do so.’
The Report also concluded that while the UK had long
been a world leader in palliative and end-of-life
care, access and provision was now ‘patchy’. It
said, ‘The Government must ensure universal coverage
of palliative and end-of-life services, including
hospice care at home.' And it called for the
Government to commit to an uplift of funding to
guarantee support for hospices that need financial
help. Currently hospices receive only a third of
their funding from the NHS, despite providing the
majority of the palliative care.
It further described a ‘pressing need’ for better
mental health support for terminally ill people and
said the Government should commission research on the
subject then report to Parliament. And there
should be a ‘national strategy for death literacy and
support following a terminal diagnosis’ to help
professionals better support a dying person and their
loved ones.
Steve Brine MP, the Committee
chairman, confirmed that, ‘The inquiry on assisted
dying and assisted suicide raised the most complex
issues that we, as a committee, have faced, with
strong feelings and opinions in the evidence we
heard.’
‘We intend the information and testimony we present in
our Report today to have a lasting legacy and, as we
set out in the initial terms of reference, be a
significant and useful resource for future debates on
the issue. That could still be during this
Parliament, of course, or after the next general
election.’
The Government has briefly responded to the
Report. This was immediately before MPs debated
that Parliamentary petition with more than 100,000
signatures, calling for the Government to allocate
time for a full debate on assisted dying and for MPs
to be given a vote on the issue.
The three-hour debate was well attended with
contributions from many MPs and from many
perspectives. Of course, not much significant
headway can be achieved in 180 minutes on such a huge
topic, but it was a useful testing of the waters
exercise. No votes were taken. Dignity in
Dying thought it had won the day. Others thought
otherwise.
One of the great unknowns at this debate was the
impending call a few days later for a 4 July general
election. Both prime minister, Rishi Sunak, and
the leader of the opposition, Sir Keir Starmer, have
committed to ensuring time to debate assisted suicide
if either is successful in their respective bids to
lead the next Government following that general
election. We will be back.
Genetic Engineering
Gene therapy for deafness
Opal Sandy from Oxfordshire was born with congenital
deafness. When she was four days old, doctors
told her parents that she was completely deaf.
Now her hearing has been restored after she became the
first person in the world to take part in a
revolutionary trial using a gene therapy called DB-OTO
and produced by Regeneron, an American biotech
company. One in every 500 children is born with
some form of auditory neuropathy. Most of these
cases are caused by genetic variations, with mutations
in the OTOF gene accounting for between 1 and
8%.
Opal’s deafness was due to a variant of this OTOF
gene which impairs the production of the OTOF
protein that is critical for the communication between
the sensory cells of the inner ear and the auditory
nerve. She received the gene therapy as part of
the international CHORD clinical trial taking place in
the UK, Spain and the USA. The Phase 1 trial is
looking at the use of DB-OTO for children with OTOF
mutations. The DB-OTO procedure, which took
place at Addenbrooke's Hospital in Cambridge, consists
of injecting a modified adeno-associated virus (AAV1)
that carries a working copy of the human OTOF
gene into the inner ear. It was conducted in
Opal’s right ear, shortly before her first
birthday. At the same time, a cochlear implant
was fitted in her left ear, to ensure she could hear
as soon as possible.
Three weeks after having the treatment, at eleven
months of age, the toddler responded to sound, even
with the cochlear implant switched off. She
improved continuously and after six months clinicians
confirmed she had close to normal hearing levels for
soft sounds. Then, at 18 months old, she started to
speak.
Professor Manohar Bance, chief investigator of the
CHORD trial and ear surgeon at Cambridge University
Hospitals NHS Foundation Trust, has said, ‘Gene
therapy has been the future of otology and audiology
for many years and I'm so excited that it is now
finally here. This is hopefully the start of a
new era for gene therapies for the inner ear and many
types of hearing loss.’
The ongoing CHORD clinical trial has three Phases and
includes 18 children worldwide. Phase 1, in
which Opal participated, consists of receiving a low
dose of the DB-OTO infused into one ear of three deaf
children. Following proven safety in Phase 1,
another three children in Phase 2 will have a higher
dose administered to one ear. Finally, if the
previous two Phases are proven to be safe, Phase 3
will consist of injecting the therapy into both ears
of another cohort of deaf children.
Already, a second child enrolled in the CHORD clinical
trial, and dosed at 4 years of age, is showing
similarly positive results six weeks after
treatment. Professor Bance added, ‘We have a
short time frame to intervene because of the rapid
pace of brain development at this age. Delays in
the diagnosis can also cause confusion for families as
the many reasons for delayed speech and late
intervention can impact a children's development.'
Who doesn’t like to hear such good news from
successful clinical trials using bioethically-sound
pioneering biotechnology such as these gene therapies?
Cancer therapy by shotgun
We probably think that cancer treatments involve
precision chemotherapy and accurate
radiotherapy. And, by and large, such approaches
work. However, there is a new, rather bullish,
approach that is gaining traction. It involves
blasting patient’s cancer cells with dozens of drugs
simultaneously in the hope of finding one that
works. Such shotgun therapy is generally frowned
upon by the medical fraternity. But read on.
Take the case of Kevin Sander, a 38-year-old
procurement manager living in Austria. His blood
cancer had returned and his treatment options were
running out. He really needed a stem-cell
transplant, but the uncontrollable extent of his
tumour precluded that.
So, in 2022, Sander went rogue and joined a landmark
clinical trial led by haematologist Philipp Staber at
the Medical University of Vienna. The study is
exploring an innovative treatment strategy in which
drugs are tested on the patient’s own cancer cells,
cultured outside the body. The research team
tried 130 compounds on cells grown from Sander’s
cancer – essentially, they were trying everything at
their disposal to see what might succeed.
One option looked promising. It was a type of
kinase inhibitor that is approved to treat thyroid
cancer, but is seldom, if ever, used for the rare
subtype of lymphoma that Sander had. He was
prescribed a treatment regimen that included the drug,
and it worked. The cancer receded, enabling him
to undergo the stem-cell transplant. He has been
in remission ever since. He has declared, ‘I’m a
bit more free now. I do not fear death
anymore. I try to enjoy my life.’
Kevin Sander’s story is an example of this kind of
intensive and highly personalised drug-screening
method – it is called ‘functional precision
medicine’. It aims to match treatments to
patients, but instead of relying on a genomic-based
approach with best-matched treatment, it throws the
lab’s reagents at the cancer cells and sees what
sticks. It may be inelegant, but it may
work. Staber’s team reports that more than 50%
of blood cancer patients on the shotgun regime enjoy
longer periods of remission than those on standard
treatments, where the proportion is a mere 10%.
The protocol is deceptively simple. Cells from
cancer biopsies are dispersed using a knife, forceps
and a nylon strainer. The resulting slurry is
distributed across a 384-well plate. In each
well is a different drug compound – chemotherapy
agents, enzyme-targeted drugs, immune-modulating
therapies and more. After a night of incubation,
lab testing reveals which drugs are active against the
particular cancer and which are not.
A growing number of groups are reporting success with
this general approach. For example, in a trial
conducted at the University of Helsinki, researchers
found that drug screening of leukaemia cells provided
informative results substantially faster than did
genomic profiling. Moreover, of 29 people with
treatment-resistant acute myeloid leukaemia (AML), 17
responded to drug-screening-informed therapies and
entered remission.
Yet this is only the beginning. At least
anecdotally, the try-everything approach can be
exciting and effective, but there are problems
ahead. For example, screening a bunch of drugs
may seem simple, but the methods used to culture
cancer cells outside the body can be technically
demanding, time-consuming and costly.
Replicating the in vivo environments for culturing
cancers, especially for solid tumours, is complicated.
The world of oncology awaits the results of Staber’s
latest trial in which he and his team compare
functional- and genome-guided approaches directly
alongside treatments suggested by standard pathology
and physician intuition. Proponents of
functional precision medicine have called it a
revolution. We shall see.
Move over CRISPR-Cas9
The CRISPR-Cas9 gene-editing system excels at altering
and disrupting genes. In many ways it has
transformed experimental biology and specifically,
treatments of diseases. However, the changes it
makes can be limited in terms of safety, efficacy and
scope. Moreover, its edits of DNA are permanent,
which can be a serious problem if the system goes awry
and introduces, for example, unwanted off-target, or
incomplete, editing.
Such engineered CRISPR systems typically consist of
two main components – a DNA-cutting enzyme, often
Cas9, and a piece of ‘guide’ RNA that directs the
enzyme to the stretch of DNA to be edited. One
of this system’s most promising medical applications
has been in producing chimeric antigen receptor (CAR)
T cells. These are made by engineering the
immune system’s T cells to attack specific proteins on
the surfaces of tumour cells. But such
DNA-editing CRISPR systems can pose safety problems
and are relatively inefficient.
Enter a new CRISPR-based system that targets a cell’s
short-lived messenger RNA rather than its DNA.
This could provide a more precise and reversible way
of designing cell therapies.
This new genetic engineering tool has been described
in an article entitled, ‘A versatile CRISPR-Cas13d
platform for multiplexed transcriptomic regulation and
metabolic engineering in primary human T cells’ by
Victor Tieu et al, and published in Cell
(2024, 187: 1278-1295).
This team from Stanford University has developed what
they call multiplexed effector guide arrays (MEGA), a
platform for programmable and scalable regulation of
the T cell transcriptome using the RNA-guided,
RNA-targeting activity of CRISPR-Cas13d rather than
the DNA-cutting enzyme, Cas9.
And because Cas13d targets mRNA it avoids the risk of
inducing permanent changes or, worse, cutting DNA in
places other than the designated target. In
addition, because the RNA exists only temporarily in
the cell, any mistakes should quickly disappear.
Active cells, such as T cells, produce a constantly
changing variety of mRNA molecules, each directing the
production of a specific protein. Cas13d cuts
the target mRNA, destroying it and preventing it from
synthesising a specific protein. In other words,
it is similar to turning off the associated
gene. MEGA goes further by allowing researchers
to create ‘multiplex’ CRISPR–Cas13d systems that can
shut down the production of multiple proteins,
effectively turning off as many as ten genes at a
time.
The Stanford team tested the MEGA system by addressing
a shortcoming of CAR T therapy called T-cell
exhaustion. If CAR T cells are activated too
many times by a chronic infection or a long-term
tumour, they become less effective. To reboot
‘tired’ T cells, the researchers designed CRISPR
systems that target mRNA involved in functions such as
energy production and sugar metabolism. Some
MEGA-treated T cells were revitalised and stopped
expressing molecular signals of exhaustion and became
better at shrinking tumours in mice.
So, now it’s from mice to men (and women). Bring
on the next generation of T-cell therapies.
Bring on the human clinical trials. Sometimes
good science can make you feel quite giddy.
Stem-cell Technology
Stem cells and glioblastoma
A rather exciting form of
immunotherapy derived from induced
pluripotent stem cells (iPSCs) has been shown to be
effective in treating brain cancer – OK, so far, only
in mice, but still exciting.
Glioblastoma (GBM) is an aggressive brain cancer with
a poor prognosis. Glioblastomas are almost
always lethal with a median survival time of 14
months. Conventional treatments, such as
surgery, chemotherapy and immunotherapy, have not
produced significant extensions of life-expectancy as
seen for many other cancers. This resistance to
treatment is partly due to the cancer's ability to
evade and suppress the body's natural immune
response. Researchers have now genetically
engineered immune cells derived from stem cells and
designed them to target and dismantle the immune
suppressive tactics employed by the tumour, meaning
they can destroy the cancer cells.
This work has been reported as ‘synNotch-programmed
iPSC-derived NK cells usurp TIGIT and CD73 activities
for glioblastoma therapy’ by Kyle Lupo et al.,
and published in Nature Communications (2024,
15: 1909).
In their study, these researchers at Purdue University
did not use traditional ‘personalised’, autologous
stem-cell therapies that require cells to be collected
and returned to the same patient. Instead, they
employed 'off-the-shelf' stem cells to generate
natural killer (NK) cells, namely immune cells known
for their ability to identify and attack cancer
cells. In other words, they engineered
allogeneic induced pluripotent stem cell
(iPSC)-derived NK (iNK) cells. These
readily-available cells eliminate the need for
additional collection procedures, which could be a
significant advantage, considering the time-sensitive
nature of brain cancer treatments.
The team directly injected these iNK cells into mice
bearing human brain cancer tumours. The outcomes
were promising, significantly improving survival times
and reducing tumour size. The next step is to
develop further this glioblastoma protocol and to
begin conducting clinical trials to treat human
patients with brain tumours, including those for whom
surgery has not been successful.
According to Sandro Matosevic, associate professor at
Purdue University, Indiana, and lead researcher in
this study, 'Our preclinical studies showed these
immune cells to be particularly remarkable in
targeting and completely eliminating the growth of the
tumours.’ And, ‘We found that we can engineer
these cells at doses suitable for clinical use in
humans. This is significant because one of the
major hurdles to clinical translation of cell-based
therapies to humans has been the poor expansion and
lack of potency of cells that were sourced directly
from patients. Using an off-the-shelf, fully
synthetic approach breaks down significant barriers to
the manufacturing of these cells.' And, ‘Our
ultimate goal is to bring this therapy to patients
with brain tumours.' And, ‘These patients
urgently deserve better and more effective treatment
options. We believe there is true potential for
this therapy, and we have the motivation and capacity
to bring it to the clinic.’
Human stem cell-based embryo
models
On 28 February 2024, the UK Government published a
so-called POSTnote with the above title. It
summarises the emerging technology of human stem
cell-based embryo models (SCBEMs). The 25-page
document is available online at
https://researchbriefings.files.parliament.uk/documents/POST-PN-0716/POST-PN-0716.pdf
(cut and paste if necessary).
This useful, but not necessarily bioethically sound,
document contains a summary of six Key Points.
They are:
1] Human SCBEMs are created from pluripotent
stem cells, these cells are unspecialised and have the
ability to develop into other cell types.
2] Human SCBEMs offer the opportunity to study
and explore the key features and processes of the
early development of embryos in ways we cannot with
human embryos.
3] The terminology describing SCBEMs can vary,
they have been referred to as artificial embryos,
synthetic embryos, stembryos, synthetic human entities
with embryo-like features (SHEEFs), embryo-like
structures (ELS), embryo models and embryoids.
4] Internationally, legal definitions and
regulations around human SCBEMs vary from no explicit
regulation to different limits on its research.
5] The International Society for Stem Cell
Research have created guidelines to address the
international diversity of cultural, political, legal
and ethical issues around the emerging technology and
its application in medicine and treatments.
6] Stakeholder suggestions towards effective
oversight of SCBEMs include (i) identifying
similarities and differences between SCBEMs and human
embryos, (ii) an independent oversight process
involving experts and lay members, and (iii)
conducting public engagement to increase public
understanding and identifying concerns surrounding the
technology.
The entire POSTnote, including these six Key Points,
contain controversial statements. Indeed, for
decades the use of human embryos in both research and
reproduction has been bioethically calamitous.
And now human stem cell-based embryo models (SCBEMs)
are similarly riddled with bioethical dilemmas.
Nevertheless, to keep abreast of emerging technologies
it is necessary to understand topics, the use of which
will be opposed by many readers.
Stem cells and spinal cord
injuries
Spinal cord injuries (SCIs) are debilitating
conditions that carry severe medical, psychological
and financial implications for those living with such
impairments. Existing treatments are limited to
symptomatic management and physical
rehabilitation. Some sort of stem-cell
regenerative medicine would be welcome.
Adipose tissue represents the most prominent reservoir
of mesenchymal stem cells, known as adipose-derived
mesenchymal stem cells (AD-MSCs). These cells
are considered attractive options due to their
availability, ease of access, and multipotency.
In addition, preclinical trials in animals with SCIs
demonstrated that AD-MSCs can regulate the
inflammatory response and promote a regenerative
environment with promising clinical outcomes.
A recent Phase 1 study, conducted at the Mayo Clinic
in Rochester, Minnesota, has shown that treatment with
AD-MSCs, derived from a patient’s own adipose tissue,
can be safe and can improve sensation and movement
after traumatic spinal cord injuries.
The findings from this clinical trial have been
reported as ‘Intrathecal delivery of adipose-derived
mesenchymal stem cells in traumatic spinal cord
injury: Phase I trial’ by Mohamad Bydon et al.,
and published in Nature Communications (2024,
15: 2201).
The ten participants enrolled in this trial had SCIs
from motor vehicle accidents, falls and other
causes. Six had neck injuries and four had back
injuries. The patients ranged in age from 18 to
65.
Participants' AD-MSCs were harvested by extracting
approximately 15ml of adipose tissue from a 1 to
2-inch incision in the abdomen or thigh. Over
the next four weeks, the cells were cultured in the
laboratory to the required dosage of about 100
million. These were then injected into the
patients' lumbar spine in the lower back. During
the following two years, each participant was
evaluated ten times at the Mayo Clinic.
Each patient was examined and graded according to the
American Spinal Injury Association Impairment Scale
(AIS). At the time of injury, eight patients
were classified as AIS grade A and two patients as AIS
grade B. At the time of stem-cell injection,
five patients were classified as AIS grade A, two as
AIS B, and three as AIS C.
At the final follow-up, seven patients displayed
improvements in their AIS grades from the time of
injection. These improvements included motor and
sensory functions, such as increased sensation when
tested with pinprick and light touch, increased
strength in muscle motor groups, and recovery of
voluntary anal contraction, which aids in bowel
function. Of the seven participants who
improved, each moved up at least one level on the ASI
scale. The three patients who showed no
response, did not improve, but neither did they
decline.
The study met its primary endpoint, namely
demonstrating that AD-MSC harvesting and
administration were well tolerated in patients with
traumatic SCIs. The most commonly reported
adverse events were headache and musculoskeletal pain,
observed in 8 patients. No serious adverse
events were observed.
In addition to evaluating its safety, this Phase 1
clinical trial had a secondary objective of assessing
changes in motor and sensory function. The
authors noted that though these results were mostly
positive they must be interpreted with caution given
the intrinsic limitations of Phase 1 trials.
Additional research with a larger group of
participants is needed to further assess risks and
benefits.
According to Mohamad Bydon, a Mayo Clinic neurosurgeon
and first-named author of the study, has commented,
‘Spinal cord injury is a complex condition. This
study documents the safety and potential benefit of
stem cells and regenerative medicine. Future
research may show whether stem cells in combination
with other therapies could be part of a new paradigm
of treatment to improve outcomes for patients.’
Miscellaneous
Terminalism – discrimination
against the dying
Bioethics, indeed, life in general, is contaminated
with -isms. In terms of discrimination there are
the deep-rooted examples of racism, sexism and
classism. Then there are the more modern cases
of speciesism, ableism and ageism. And finally,
there are the newbies of nimbyism, transgenderism and
terminalism. What was that last one? It is
nothing to do with missed buses or trains. The
philosopher Philip Reed is the culprit and the
proponent.
In an article under the title, ‘Discrimination against
the dying’ and published in the Journal of Medical
Ethics (2024, 50: 108-114), Dr Philip
Reed of Canisius College, Buffalo, New York, makes his
case. He defines terminalism as ‘discrimination
against the dying, or treating the terminally ill
worse than they would expect to be treated if they
were not dying.’
Furthermore, Reed asserts that terminalism goes
largely unrecognised, especially in healthcare
settings. He provided four examples – hospice
eligibility requirements, allocation protocols for
scarce medical resources, right to try laws, and right
to die laws.
Inevitably, the issues of euthanasia and assisted
suicide are also sculking around nearby. Are,
for example, people who want to die being
discriminated against because of existing
legislation? Reed answers, ‘In denying that the
terminally ill are committing suicide by accessing
assisted death, the professional organisation most
committed to preventing suicide has given up its
responsibility of addressing suicidal ideation among
the terminally ill. This is terminalist: purely
on the basis of group membership, one group gets
suicide prevention and another gets suicide
assistance.’
He continues, ‘Moreover, the availability of the
option of assisted death only for the terminally ill
negatively influences the terminally ill who wish to
live by causing them to doubt their choice. When
assisted death is available only to the dying, a dying
person may be prone to feel a need to justify his
existence in a way that the non-dying, not having the
option, need not do. This puts the dying at a
disadvantage.’
Reed has other arguments to make. For instance,
he states that, ‘… discrimination against the dying
occurs regularly in high-capitalist Western
cultures. I think terminalism is relatively easy
to see, that it has been hiding in plain sight, and
the fact that we have not yet confronted it reveals in
part our blind spots and prejudices. We don’t
want to think of ourselves as discriminating against
yet another vulnerable group, yet we are plainly doing
so.’
Reed concludes his searching article, ’The reason that
terminalism matters is that dying persons
matter. Our willingness to treat such patients
badly assumes a kind of fatalism – where we imagine
that a life with very little future means a less
valuable life. Of course, there is nothing new
in pointing out that the terminally ill deserve
better. Certainly, the plight of the dying and
material attempts to improve it have a long
history. Yet the fact that they are subject to
discrimination, as I have argued in this paper, shows
a special kind of mistreatment that they suffer.
It is a matter of unfairness or harm or both that the
dying withstand disadvantageous treatment merely on
account of their group membership. Confronting
terminalism forces us to ask an uncomfortable
question: what do we owe the dying and how might we
treat them as equals with those who have indefinitely
long to live?’
This is just over 6 pages of thought-provoking
stuff. Philip Reed is professor of philosophy at
Canisius University, a Jesuit-affiliated
institution. Its motto is cura personalis
– care for the whole person.
The asymmetric start of life
You already know the bioethical biologist’s
refrain. When sperm plus ovum unite, a single
cell is produced. It is a zygote. It is a
sort of 1 + 1 = 1. This zygote is a new,
genetically-unique human life, etc., etc. Then,
within some 24 hours, the 1-celled zygote divides to
become a 2-celled blastomere. The marvels of
cell division are about to take off, big time – it is
2, 4, 8, 16, and so on. Meanwhile, the process
of cell differentiation switches on allowing these
totipotent embryonic stem cells to become specialised
cells, such as liver, hair, toenails, and so forth.
Cell differentiation obviously results in cells that
are no longer identical. However, the zygote and
the blastomeres, the first two cells of the first cell
division, have long been thought to be identical
totipotent cells. Surprisingly, this now seems
unlikely. Our current understanding of the
development of human biological symmetry is not quite
right – it needs amending.
This is the conclusion of a research paper entitled,
‘The first two blastomeres contribute unequally to the
human embryo’ by Sergi Junyent and colleagues and
published online in Cell (13 May 2024).
The authors include members of the team led by
Professor Magdalena Zernicka-Goetz from the Department
of Physiology, Development and Neuroscience at the
University of Cambridge.
To understand this process better, Zernicka-Goetz and
her collaborators first tracked cell lineage from the
two-cell stage. They injected mRNA for green
fluorescent protein (GFP) into one of the two cells of
the zygote. Thus, they could determine the
contribution of each cell to the development of two
early structures – the trophectoderm (TE) that becomes
the placenta and the inner cell mass (ICM) that
eventually produces the epiblast, or foetal tissue,
and the hypoblast, or the yolk sac.
By tracking their subsequent development, they found
that one population of cells dominated in either the
ICM or the TE, but that this imbalance was greatest in
the ICM. Within the ICM, progeny from one clone
at the two-cell stage dominated the population of the
epiblast, while the composition of the hypoblast was
split between cells of the two originating clones.
Put another way, they found that when a human embryo
is one day old and comprises just two cells, only one
cell will create most of the foetus in addition to
placenta, while the other cell will create
placenta. In other words, the first two
blastomeres contribute unequally to the human
embryo. According to Zernicka-Goetz, ‘They are
not identical. Only one of the two cells is
truly totipotent, meaning it can give rise to body and
placenta, and the second cell gives rise mainly to
placenta.’ This means, we all started our early
lives asymmetrically.
This challenges the previous notion that each cell at
the 2-cell stage contributes equally to all parts of
the developing embryo and placenta, and it suggests
that embryo asymmetry occurs much earlier than
previously believed. Those first two cells are
not equivalent – there is imbalance early on because
each cell of the blastomere do not give rise to half
of all the cells in our bodies.
This is intriguing biological stuff. Moreover,
there are some interesting political and economic
undercurrents in this research paper – it is not all
about science. For instance, the authors state,
‘The reason behind this imbalance is not known.
Indeed, when and how cell fate decisions are initiated
in the human embryo remain long-standing questions,
because the access to human embryos for research is
extremely limited.’ This is an indirect plea for
the Human Fertilisation and Embryology Authority
(HFEA) to press for a loosening of the law restricting
destructive embryo experimentation and for easier
access to more and later-developed human embryos.
The authors then pitch their puff for future
funding! Their Departmental article (published
on 15 May) states, ‘It is hoped that these findings
will improve the success rates of IVF pregnancies
through a deeper understanding of early embryo
development and increase knowledge of the origins and
developmental contributions of cell lineages, which
has implications for the cellular inheritance of
mutations and how they might contribute to cancer and
other genetically determined disease.’ Come on,
who could be against improving IVF successes and
cancer cures? In plain English, give us a large grant,
please!
In summary, this is fascinating, cutting-edge human
biology. We know so little. However, there
is a cost to gaining such knowledge.
Undergirding all this sort of research is the fact
that it depends upon a steady supply of human embryos,
and these are inevitably destroyed. Indeed, for
this current work, Zernicka-Goetz relied on an IVF
clinic that could provide her laboratory with 54
fertilised eggs, zygotes that had not yet fully
completed their first cell division. Eventually
they were trashed.
Right- or left-handed?
For what it’s worth, I’m sinister, along with about
10% of the world’s population. However, this is
not strict demographic arithmetic – unexplained
statistical blips occur. For example, since WWII
there have been fourteen different US Presidents and
six, or a hefty 43%, of them have been
left-handed. But that is another story. I
can also roll my tongue along with about 65% of the
population, but that too is another story. And I
can do other party tricks, but this is not the place
to brag of my biological feats.
So, what makes us handed? Handedness is linked
to brain asymmetry, as right-handedness reflects
left-hemisphere dominance for control of the preferred
hand, and vice versa. But how did this
handedness start? There will have been both
physical components and social pressures. But
before those became significant there must have been a
biological element.
Handedness has long been a fascination and its
associated literature could already fill several
library shelves. Here is one of the latest
contributory ideas. Your handedness may have
been decided by the protein content in you as an early
embryo, yes, in little embryonic you! At least
that is the gist of an article entitled, ‘Right- or
left-handed? Protein in embryo cells might help
decide’ by Sumeet Kulkarni and published in Nature
(2 April 2024).
Take a biological step back from this issue of protein
content and we are faced with the fact that its
drivers will have been the genes that coded for those
structural proteins. In other words, genes could
have determined the dominant side of the human brain,
and yes, your brain too, and thus also your
handedness.
During the embryonic stage of human development, the
left and right brain hemispheres get wired
differently, which in part determines our innate
behaviours, such as which way we lean when we hug
someone, on which side of our mouth we tend to chew
our food and, most prominently, which hand is our
dominant one. And because most people have a
clear preference for one hand over the other, finding
genes linked to handedness can provide clues for the
genetic basis of the brain’s left–right asymmetry.
Isn’t this fascinating? An earlier study by
Gabriel Cuellar-Partida et al., and entitled,
‘Genome-wide association study identifies 48 common
genetic variants associated with handedness’ and
published in Nature Human Behaviour
(2022, 5: 59-70) found that these variants
were associated with left-handedness. They were
mostly located in non-coding regions of the DNA
including sections that could control the expression
of genes related to tubulins. Tubulins are
proteins that polymerise into long, tube-like
filaments called microtubules, which can oversee the
shapes and movements of cells.
Kulkarni majors on the work of Dick Schijven and
colleagues from the Max Planck Institute for
Psycholinguistics, in Nijmegen, the Netherlands.
In particular, he cites their recent article entitled,
‘Exome-wide analysis implicates rare protein-altering
variants in human handedness’ published in Nature
Communications (2024, 15: 2632).
Schijven and his collaborators, looked for rare
genetic variants in protein-coding sequences.
They analysed the genetic data of 313,271 right-handed
and 38,043 left-handed individuals as recorded in the
UK Biobank database. Their findings also
implicated tubulins, those structural proteins that
build the internal skeletons of cells.
Furthermore, they discovered variants in a tubulin
gene, dubbed TUBB4B, which were 2.7 times more
common in left-handed people than in right-handers.
According to Clyde Francks, senior author of the Nature
Communications paper, these rare variants, ‘can
give clues to developmental mechanisms of brain
asymmetry in everyone.’ In addition, he
maintains that these findings pave the way for future
work to determine how microtubules, which themselves
have a molecular ‘handedness’, can give an ‘asymmetric
twist’ to early brain development.
Perhaps microtubules influence handedness because they
form cilia – hair-like protrusions in cell membranes,
which can direct fluid flows in an asymmetric way
during development.
Wonderful and beguiling! Ponder it next time you
seemingly unconsciously decide with which hand to
throw that ball.
USA
and Elsewhere
A frozen embryo is a …..?
The USA and the UK do things differently. In
legal matters, the USA relies on its Supreme Court,
whereas the UK trusts its Parliament. Think of
abortion and its legalisation. In 1973, it was
the Supreme Court that handed down its verdict in the
Roe v. Wade case. The UK’s 1967 Abortion
Act was a Parliamentary affair. The former was
based on the Constitutional concepts of liberty and
privacy, while the latter focussed on the physical and
mental health risks to women. Different
procedures, yet similar outcomes – both were landmark
decisions, both permitted widespread abortion across
both countries.
It took another 50 years before the perceived ‘right
to abortion’ in the USA was successfully
challenged. Again, it was the Supreme Court that
ruled in the Mississippi case of Dobbs v. Jackson
Women's Health Organization in June 2022.
It declared that there was no Constitutional
protection for abortion. Roe v. Wade was
therefore overturned. The upshot was
massive. Federal abortion law was returned to be
determined by individual states and many implemented
bans or restrictions on abortion access.
In February 2024, a third landmark bioethical case,
that of LePage v. Mobile Infirmary Clinic, Inc.,
was decided. The Supreme Court of Alabama ruled
that, under state law, frozen human embryos are
children.
The case arose from a wrongful death lawsuit brought
by three couples involving the loss of their frozen
embryos at the IVF clinic of Mobile Infirmary, Inc.’s
Center for Reproductive Medicine. The plaintiffs
were James and Emily LePage, Felicia and Scott Aysenne
together with William Tripp and Caroline Fonde.
The couples had undergone IVF treatment, resulting in
the creation of several embryos. Some were
transferred to the women and some were stored in the
clinic’s cryopreservation facility for possible future
use. However, in 2020, those frozen embryos were
destroyed when a patient from a nearby hospital
wandered into the Center, tampered with an unsecured
freezer, resulting in the embryos being dropped on the
floor.
The couples sued under Alabama's 1872 Wrongful Death
of a Minor Act, a statute that allows parents of a
deceased child to recover punitive damages for their
child’s death. They sought damages for wrongful
death, negligence, wantonness plus mental anguish and
emotional distress.
In 2022, the Alabama trial court dismissed the
plaintiffs’ claims. It held that the embryos did
not meet the definition of a ‘child’ under the 1872
Act, therefore their loss could not give rise to a
wrongful-death claim.
However, in February 2024, on appeal, the Supreme
Court of Alabama disagreed and reversed the lower
court’s decision. Alabama’s Supreme Court
summarised its 25-page ruling in the following terms,
‘The central question … is whether the Act contains an
unwritten exception to that rule for extrauterine
children – that is, unborn children who are located
outside of a biological uterus at the time they are
killed. Under existing black-letter law, the
answer to that question is no: the Wrongful Death of a
Minor Act applies to all unborn children, regardless
of their location.’
Furthermore, it stated that, ‘The statutory term
“child” in the Act includes an “unborn child”, and it
held ‘that nothing in the Act creates an exception for
“unborn children” who are not physically located in
utero … at the time they are killed.’ In other
words, ‘The relevant statutory text is clear: the
Wrongful Death of a Minor Act applies on its face to
all unborn children, without limitation.’
‘“Unborn children” are “children” under the Act,
without exception based on developmental stage,
physical location, or any other ancillary
characteristics.’
In his concurring opinion, Chief Justice Tom Parker
drew attention to Alabama's Constitution, which
declares a state policy to ‘recognize and support the
sanctity of unborn life.’ He held that, ‘Human
life cannot be wrongfully destroyed without incurring
the wrath of a holy God, who views the destruction of
His image as an affront to Himself. Even before
birth, all human beings bear the image of God, and
their lives cannot be destroyed without effacing his
glory.’
The Court’s assertions sent shockwaves among the
providers of IVF and other assisted reproductive
technologies (ARTs), across the USA and beyond.
According to media reports, several IVF clinics in
Alabama and elsewhere paused or abandoned
treatments. In addition, public figures and
advocacy groups were quick to respond. For
example, in a statement, the Alabama division of the
ACLU (American Civil Liberties Union) not
unsurprisingly insisted that, ‘The Alabama Supreme
Court has grossly overstepped its role by classifying
frozen embryos, single-celled fertilized eggs, as
children’ and, ‘This ruling has terrifying
implications for people in Alabama.’
In the Court's only dissenting opinion, Justice Greg
Cook warned the ruling would ‘almost certainly’ end
the creation of frozen embryos in Alabama, and he
urged state legislators to consider the matter.
However, the Alabama Attorney General, Steve Marshall,
confirmed that he has no intention of using the recent
Alabama Supreme Court decision as a basis for
prosecuting IVF families or providers.
The legal impact of this IVF decision is probably
limited to Alabama and legal experts consider it is
unlikely to be appealed to a higher court, given that
it dealt with a question of Alabama state law.
Indeed, on Friday 3 May, the Alabama Supreme Court
declined to reconsider its controversial ruling.
Justices, in a 7 to 2 decision, without comment,
rejected a request to revisit its decision.
So, will IVF be banned, limited or ignored? Some
IVF advocates have nebulously contended that the way
forward with IVF is to respect ‘the special moral
status of the embryo in an appropriate manner’ –
whatever that claptrap means. Others, such as
Senators Ted Cruz of Texas and Katie Britt of Alabama,
have gone to law and introduced a bill called the IVF
Protection Act that seeks to ensure that no state
prohibits access to IVF services.
A first practical step is obvious. Forbid the
creation of surplus embryos and their cryogenic
storage. The German 1990 Embryo Protection Act
already requires this and it also prohibits the
fertilisation of more ova than will be transferred in
one IVF cycle. A second step is to store only
unfertilised ova. A third step is to ban IVF
outright. While that may not be feasible, the
bioethical mantra still stands – IVF is best avoided.
Abortion in Florida
This is now post-Roe America and already many
states have decreed their own abortion rules. On
1 May 2024, a new abortion law came into effect in the
Sunshine State. It generally prohibits abortions
after six weeks. Somewhat strangely, a month
before, on 1 April 2024, Florida's Supreme Court
delivered two rulings on abortion with competing
consequences.
First, the Court upheld the state's right to ban
abortion, giving the green light for the six-week bar
to take effect from 1 May. This near-total ban
blocks almost all abortion access in the US
South. Florida had been something of a haven for
those seeking abortions, because it is surrounded by
states that had already implemented six-week or total
bans.
Florida is perhaps the key battleground of the
abortion battle. It is the USA’s third most
populous state and the ban may affect more women than
any other statewide veto since the repeal of Roe.
According to the Guttmacher Institute, the
pro-abortion research group, just over 84,000 women
had abortions in Florida in 2023.
The new ruling has been applauded by national pro-life
activists, many of whom see a six-week ban as the gold
standard for abortion policy. According to Katie
Daniel, Florida’s policy director of the Susan B
Anthony Pro-Life America organisation, the decision
was 'a victory for unborn children.'
On the other hand, pro-abortion advocates maintain
that Florida's six-week law is particularly
restrictive, requiring patients seeking abortions to
have two in-person doctor appointments, with a 24-hour
cooling-off period in between. Anna Hochkammer,
executive director of the pro-choice group Florida
Women's Freedom Coalition has said, ‘At six weeks most
women have no idea that they're even pregnant. A
mammoth health crisis is about to befall us.’
In the second Florida Supreme Court ruling, announced
on 1 April, and by a 4-3 vote, the Justices approved a
November ballot initiative that, if approved by
Florida’s voters, would overturn the six-week ban and
enshrine broad abortion access within the state's
Constitution. What a mess!
November 2024 is warming up to be a politically hot
month for abortion. Besides the Florida
initiative, there is the matter of the 60th
quadrennial Presidential election on Tuesday 5
November. Between now and then, political
uncertainty will abound, but certainty declares that
abortion will be an intense, even incendiary, issue
during the campaign and afterwards. Inter alia,
we should also find out what Biden and Trump really
think about abortion.
Irish politics
If politics can be erratic, Irish politics can be
eldritch (look it up). On Saturday 9 March 2024,
the Irish Government announced the results of two
referenda held the day before.
The Irish electorate had been faced with a proposal to
alter the wording of the Constitution to include
families that are not based on marriage. It was
defeated with 67.7% voting 'No'. A second
proposal was to change the wording around the role of
women in the home – it was rejected by an even greater
margin of 73.9%.
Taoiseach Leo Varadkar (the Irish prime minister) said
it was clear that both amendments had been ‘defeated
comprehensively on a respectable turnout.’
Here is the Republic’s nitty-gritty ethical
paradox. These results demonstrate the apparent
Irish intransigence to progressive politicking.
It sounds like conservative Roman Catholic
dogma. And yet, these are the very same people,
who in May 2018, overturned the age-old Irish ban on
abortion, by repealing the Eighth Amendment of the
country’s’ Constitution. The new law came into
effect on 20 December 2018 meaning that abortion was
permitted in the first 12 weeks of pregnancy and in
later cases where the woman’s life or health is at
risk, or in cases of fatal foetal abnormality.
Those are typically orthodox conditions of European
abortion law. It sounds most unlike conservative
Roman Catholic dogma.
The Irish are a complex race, but they love a good
referendum. In May 2015, the Republic voted
overwhelmingly to legalise same-sex marriage in an
historic referendum. More than 62% voted in
favour of amending the country's Constitution to allow
gay and lesbian couples to marry. It was the
first country in the world to legalise same-sex
marriage through a popular vote.
All this begs a fundamental question – do the Irish
have some sort of split moral personality? It’s
very eldritch.
