Misdiagnosed PVS for 23 years

http://www.popsci.com/science/article/2009-11/man-comatose-23-years-was-actually-conscious-all-along

This man was extraordinarily lucky to be alive to tell his story: that for 23 years, they thought he was in PVS state, not realizing that he was actually paralysed but fully conscious of everything that happened around him. This news didn't come from a particularly pro-life publication; it just reiterates how flimsy are the criteria for brain death. It is particularly interesting to me as we now have classes about anatomy, pathology, and inevitably, organ transplant and the polemic around it.

This one is from LifeNews with some commentary on how this episode affects debate about PVS determination and ethical implication.

How to explain yourself when asked about abortion

I've been intrigued by the whole abortion-prolife businesss since I first encountered it in 2003. At that point of time I was nominally Catholic, and held the view that choice is good, very good indeed, for a woman to choose whether she wants to abort her child or not. "Who's the state to say whether a woman should have a child or not?". I was also, at the same time and unsurprisingly, a nihilist. This learning about the arguments of prolife movement, based on natural law and then from the point of view of the Catholic Church, kind of "brought me back" to rediscover the joy of life within the Church. Hence this topic holds a special place in my heart.

It's July 30th when I began writing this. Not a particularly special day, but as I helped some friends to find facts to prepare a prolife presentation, I realize that despite a mountain of information available about abortion -- from both its advocates and from those who says it is a mortal sin, I haven't found one that summarizes it comprehensively. I suppose sometimes it seems too much to compress thousands of years of learning that support some of the arguments brought forth by its most vocal defender, the Catholic Church.

So I'm going to attempt to write a little bit more systematically, specifically about why abortion is not reasonably acceptable, not even mildly tolerable. Despite numerous 'rationales' proposed by its proponents, I am firmly in the camp that believes that it is an atrocity against the human race.

One last note: this is not meant as an attempt to 'win' anyone over. My treatment of the subject of abortion will spread over many areas but I will not elaborate too much, since my primary audience will be those people who *already* believe that abortion is wrong, but need a quick primer in articulating *why* exactly it is wrong, and how to answer common straw-fish arguments thrown by 'the other side' about any possibly good reason to support abortion.

So here we go; below are the common polemical arguments presented from the Pro-Choice Camp:

1. Fetus != Baby
I'll let the pictures speak for themselves. Within a few weeks, possibly before the woman realizes she is pregnant, what is growing in her womb is not a blob of cells. There is no logical or mythical line that a fetus must cross in order to become a baby. You want to talk about dependence? Then most kids don't cross that line until they go to college!

2. Fetus != Person, therefore it has no protection of a person under the law
There's no logical 'beginning' of a person before or after fertilization. A day-old baby is the same person as he was a day before his birth, the same person as he was 2 days before his birth, and so on, until we come to a logical beginning, which is fertilization. During fertilization, a new creature with a complete set of DNA is created - even as a single-celled organism before the cells multiply.
Historically, personhood doesn't begin until after the person is born -- like in Roman times, when the father has to 'lift up' the baby to proclaim it as his son, if not, to reject it.
Philosophically, that's bosh. We've established that the fetus is a baby, and that baby is the same person, before and after birth. That baby cannot, at some point of time within its mother's womb, suddenly become a rabbit or a bird at birth. A human fetus grows to be a human person. A Person has human rights.

3. It's just a blob of cells, a part of a woman's body; she decides what she can do with her body.
Yes, a woman, or any free person for that matter, has the right to do what she wants to do with her body. A fetus isn't a part of a woman's body the way an arm or an eye is.

4. It's just a blob of cells; it's not murder.
We've established that the fetus is a baby, and a person. Premeditated, deliberate, involuntary termination of a person's life, in any sense, is murder. There's a law protecting the eggs of a bald eagle. Clearly, everybody knows that destroying an egg of a bald eagle destroys one more eagle. That which is growing in a pregnant woman's womb, is a baby. Clearly, to destroy it is to kill one more person.

5. Every child a wanted child
Boy, this is a slogan from the Clinton era. Pregnancy is never accidental, just as sex is never accidental. Pregnancy is an intended end of sex, biologically speaking. Every couple who has sex should keep in mind that their action indicates biologically that they want to conceive a child.

6. Abortion is a healthcare right, a woman's right
Several movements have begun to push for abortion to be proclaimed as a woman's right, cleverly stowed under the slogan of women's healthcare – which has become synonymous with abortion and contraception. Pregnancy is not a disease. Human rights can never, ever, include rights that deprive another of his basic human rights. Even in the case of a pregnancy that "endangers" the health of the mother, abortion is still not a right - it is only a tolerably evil consequence of saving the life of the mother. (More about this myth of dangerous pregnancy: only in very rare conditions make pregnancy hazardous to a woman, which are certainly not present in the majority of abortion-for-health cases)

7. Abortion should be 'safe, legal and rare'
Another Clintonesque legacy. Stats showed that abortion numbers spiked during the Clinton years. Relative safety, legal status and easy availability (sometimes subsidized or covered by insurance) does not exactly discourage its practice, you see.

8. Abortion has helped curb crime in dangerous neighborhood
There is higher density of abortion clinics at poorer neighborhoods. In New York, under Rudy Giuliani, abortion was used as part of the zero-tolerance strategy. It is a form of eugenics, or baldly put, genocide. It is saying that 'poor people' should not be encouraged to have children, and this slippery slope will lead to a situation where poor people will not have rights to have children. Social determinism: not all who grew up in poor neighborhood grew up to be criminals. Guess which ethnicity has experienced the greatest number of abortions? 37% of all abortions are done on African-American women, more babies (nearly 15 million -- PDF!) have died through abortion in the last 36 years than the number that slavery killed.

9. Abortion helps us to be ecologically friendly
(I must admit this is one of the more 'loco' arguments) Are human beings parasites? Is the earth overpopulated? 40 years ago, scientists say that at the rate human beings are propagating, there will not be enough food for everyone. Well, they've been proven wrong. Human beings are not only consumers but also producers whose creativity transcend conventional growth projection. As a side point, artificial engineering of population, made countries like China, and a large part of Europe experience demographic 'winter'.

10. Abortion is Pro "choice"
When the other side talks about 'pro-choice', this choice is never the choice of the baby, always of the mother. Thus the strong wins. This is pure discrimination, dictatorship of the powerful.

11. Abortion is legal
Today, in the US and in many parts of the world, yes, it is legal. But abandonment is not. Abandonment of a newly born child, say in a trash bin, is a crime. Abandonment of a child that survives abortion, say in an abortion mill, is a crime. Is it not inconsistent, not to mention absurd, given the legality of abortion? Have you ever given it any thought? For many in the prolife movement, these laws are seen as steps towards more prolife legislation.

12. Are you ready to support the baby born out of wedlock?
This is a form of ad-hominem attack, which moves the argument from the morality of the act, to the person who defends or opposes it. In reality, the Catholic Church, being one of the most vocal opponents of abortion, is also the greatest provider of social & medical service in the US (and I suspect in many other countries as well). She walks the talk.

13. Prevention is better than cure.
#1 – Abortion is NOT a disease!
#2 – Stats show that free availability of contraception does not correspond to lower rate of abortion. It stands to reason that increased false sense of security gave rise to promiscuousness.

14. Morning-after pills are not the same as abortion.
Morning-after pills contain hormones that prevent implantation of a fertilized embryo, often given to victims of rape, or those who have had 'unprotected' intercourse. In other words, a baby may (or may not) have been conceived but could not 'latch' onto the mother's womb and is subsequently killed. While it is intended to prevent ovulation and prevent fertilization, taking the morning-after pills may be an abortifacient act if fertilization has already occurred.

15. I don't agree with it, but I will protect the woman's right to choose...
This is like saying: I don't agree with slavery, but I wouldn't help my neighbor's slave escape and I certainly won't vote to end it either. Bull.

16. I don't agree with it because I'm “Catholic / Jewish / Muslim / Evangelical / <insert your own faith here>” but I won't impose my belief on others
Public square is where faith & reason meets, to throw it out of public square is a form of dictatorship of laicistic relativism. Should we hang our faith at the doors when we step into our offices? Should the Church not build hospitals and schools, because that reflects their belief that nurturing the body and the mind are good works? Should Bl. Damien not have served the leper community in Molokai? Should Mother Teresa not bother to help the poorest of the poor in Calcutta? All beliefs influence public decisions.

Additional reasons why abortion should not be seen as a normal part of our lives...
Loss of protection of conscientious objectors (eg. FOCA)
If abortion gains status as a right, then as a consequence, medical professionals need to protect these 'rights'. A pharmacist cannot refuse to dispense abortifacients, and doctors have to supply abortion service on demand, because they are seen as basic rights of the patients, which must be upheld by adherents of these professional standards.

Aborted fetus as a source of embryonic stem cells
Aborted fetus is a source of embryonic stem cells (ESC). As long as there is a steady supply of aborted fetuses, there is a steady supply of ESC, hence perpetuating this vicious cycle of supply-demand that extols their price in terms of human lives.

Aborted fetus as a source of donated organs
Aborted fetus can been seen as a source of donated organs. And why not? If abortion is seen as a right, and not a tolerable evil as it is seen today, then logically, a utilitarian end can be found for these unwanted consequences. What's stopping them from being used as a source of organs?

That's all I have for now, I hope it helps somebody out there.

The changing tide

For the longest time, any medical breakthrough achieved using adult stem cells are hardly ever reported in the mainstream media. If it does, it appears under the generic heading of "stem cells" carrying the ambiguity of whether it has employed embryonic stem cells or the adult stem cells..

Last week, I noticed for the first time, the phrase "adult stem cells" appear in Google News. Sure the news selection in Google News works 'randomly', sure these articles were not published in big-name newspapers, but there are some differences now:

1. The adjective "adult" appear alongside "stem cells" in the titles more frequently now. One doesn't have to scan to the last sentence in the opening paragraph to find out whether it's about embryonic or adult stem cell.

2. The article isn't ended off with a 'helpful' explanation of what adult stem cells are, and why they aren't as 'powerful' as embryonic stem cells.

Here are some latest articles about iPS stem cells being used in cardiac treatment.

Aborted babies as organ donors anyone?

This bone-chilling suggestion was given by Sir Richard Gardner, an 'advisor to the Royal Society and the Human Fertilization and Embryology Authority' at an Oxford International Biomedical Center.

Another professor interviewed, Stuart Campbell, said he had no objection, since "if they are going to be terminated, it is a shame to waste their organs."

While this is horrifying and morally repugnant on so many levels, it comes as no surprise. Ironically, the argument of the "pro-choice" crowd is that it is no baby but 'a blob of tissues' that is being removed from its mother's womb. How can a 'blob of tissues' conveniently have organs that might go to many patients on the transplant waiting list?

Read the article here.

Once the baby is not treated as a person, it becomes either a property of its mother, or creatures made in the lab. Whatever happens next is anybody's guess.

New, non-invasive prenatal testing method

Some researchers in Stanford had discovered that using DNA sequencing on a pregnant mother's blood, one would be able to tell whether the baby she carries is having Down's syndrome. Since it is still at experimental stage, the sample size was only nine women, with 100% accuracy.

While this is a good move to protect the baby from miscarrying (a risk that is present with amnioscentesis - a procedure that is synonymous with prenatal testing today), I think this might make it easier for pregnant women to 'screen early' (as early as 14 weeks, the study cited) for genetic disabilities in the baby and might, might, just increase their propensity to abort any less-than-healthy baby!

Drawing lines

This evening, browsing Google News, I clicked on a story headline simply because its title is so arresting: "Bush got it right on stem cells". Before this evening, I did not know who is Charles Krauthammer, the author of the story; so I didn't know whether he falls under the 'conservative', 'neocon' or 'leftist' inclination, but the title itself is simply provocative. It is very rare to hear President Bush being praised for anything these days.

In the last few weeks, anyone who's watching the bioethics field, or is simply curious about the latest scientific breakthrough, must have heard of some wonderful news about IPS cells (induced pluripotent stem cells)—which are essentially stem cells that did not come from embryos and therefore did not involve killing of anyone.

Soon after this breaking news, there came another piece of even better news: IPS cells that were not created using a protooncogene, which earlier was used and was feared to induce cancer in the subjects.

Since I'm not American and do not pay taxes to the US, I have no comments regarding her president; only that Bush was right to make the stem cell issue a moral issue and draw a line. The Catholic Church, whose teaching I subscribe to, is unambiguous on this issue: life begins at conception, therefore harvesting stem cells from embryos is equivalent to killing of innocent lives, always an intrinsically grave evil.

While Krauthammer himself is in favor of a more 'liberal' policy on ESC research, he rightly pointed out that the slope is very slippery. He reiterated the need to draw a firm line, and pointed the dubious examples of 'populist' politicians who kept continuously re-drawing and 'retreating' their positions. If nothing else, Bush earned a place in American history through this one policy.

What, thought, what if, the IPS breakthrough had not come about? Prior to them, there have always been other sources of "adult" stem cells, such as those that are obtained from umbilical cord blood cells. Bottomline is, no good end can ever justify evil means.

Pluripotent vs embryonic stem cell reseach

The US President, George W Bush, has just—once again—vetoed a bill that would allow federal funding for embryonic stem cell (ESC) research. While it's probably not surprising, given his nominally pro-life voting records, it's curious why the same bill is "resurrected" over such a short period of time. So it got me started to read some recent news about ESC.

Some curious facts and issues surrounding this veto:

1. Renaming of the "Human Embryonic Stem Cell Registry" to the "Human Pluripotent Stem Cell Registry"

Along with the veto, he also signed an executive order, in support of so-called "pluripotent" stem-cell research— touted as alternative, ethical, sources of stem cell research.

2. Definition of Pluripotency

If my limited knowledge and memory serve me right, the term 'pluripotent' is typically applied to non-embryonic stem cells. An embryo is made up of totipotent cells, which contain the complete genetic information needed to 'manufacture' all the cells of the body, as well as pluripotent & multipotent cells. To simplify the meaning of this terminology: totipotent cells are found in the earliest stages, the pluripotent cells are found after 3 or 4 divisions, and multipotent cells are created after further divisions. Totipotent, pluripotent, and multipotent cells are all present in the embryo, but only pluripotent and multipotent cells can be found in adults.. How they differ exactly and why most supporters of ESC seem to be after the highly plastic ESC, are beyond my field.

It just seems as if the use of this term is deliberate, to stress that the source of this line of stem cells is not embryonic.

3. Definition of Embryo

The article above, seems to highlight recent discoveries of making adult stem cells behave like ESC through a process called "altered nuclear transfer". While stem cells obtained through this way is not technically destroying human embryos, there is a question of whether the adult cells reprogrammed to act like embryonic stem-cells are 'sometimes able to develop into full embryos again' by a process known as "regulation" - then what is present is potentially a human being... which makes this line of stem cells no different than ESC.

4. Definition of Life

It seems to me that restricting federal funding for ESC research is not sufficient if Bush truly believes that ESC are indeed human beings at embryonic stage! To still allow ESC research on private funding would be like saying, privately-funded killing is morally fine but the state will not fund such deeds. The supporters of ESC research would see through this duplicity and keep pushing the bill. To be consistent to the definition of life ("life begins with love"--George W Bush, 2006) at conception, it demands no less than a total ban.

Some links to articles that summarize the reprogramming of adult stem cells (in mice): here, here and here.

And a link to article about using the morality of using 'dead' ESC here.

Embryonic vs Adult Stem Cells


I think most educated Catholics out there would already be familiar with the moral and scientific arguments against embryonic stem cells. This video produced by the Family Research Council put them in a nutshell. Just so you can spread this to others.

Placental Stem Cells

There seems to be a bias in MSM reporting against the less glamorous adult, or placental, or cord-blood stem-cells. I'm no expert in stem cell research: some have argued that while these placental stem cells' lack of plasticity seems to have avoided the cancerous growth, they may still face rejection from the body's immunity once they have differentiated into the different types of cells. Yet so far, it seems like these stem cells, not as plastic or totipotent as embryonic stem cells, have yielded concrete result in real treatment.

It is thus refreshing to read this article from wired.com, which is normally a very liberal outfit that is pro-everything-in-stem-cell-research.

Awakened from vegetative state

Scientists have managed to rouse a small number of people from a permanent vegetative state using the insomnia drug zolpidem, giving hope to the relatives of those in such a condition.

Original article here:
Sanofi-Aventis’s drug zolpidem wakes patients from a vegetative state.

Methinks there are many more conscious, living & breathing people who needs to be awakened from a spiritual vegetative state! Jokes aside, read the article & what do you think is the catch ;)

In Memoriam: Terri Schindler Schiavo

This year's March 31st marks the 1st anniversary of Terri Schiavo's death. She died of dehydration after being denied food and water for 13 days. Thirteen days! The cruelty surrounding her death circumstances was astonishing to the world: people have been known to fight for the right to humane death for prisoners on death row, and even animals.

Whether or not Terri was in a 'PVS' state, what she and her family went through was a cold wake-up call to respond to the growing voice that supports euthanasia, even involuntary euthanasia.

I don't know about my own country, but Singapore has Advanced Medical Directive that allows one to state that s/he should not be given "extraordinary life-sustaining treatment" in the event that one is incapable of making that decision (terminally ill or unconscious). I remember, many years ago—around '95-'96, our priest at the Cathedral spent months and months of homily to speak of this initiative.

I remember a story of a woman who was temporarily paralyzed and could not tell the nurses that she wanted to be fed (against a previously written directive) and not starved or neglected until death. When I look at this directive now, I wonder whether there are any directives that would protect my wish to be cared for (food & water & the rest) in the event that I become incapacitated?

I am sorry to hijack this thread about Terri; but I think everyone, even if incapacitated, has a role to play in their immediate family and in their circle of friends. The idea that fulfilment can be found only through fulfilment of self is distinctly self-centered. For what does our life mean if it is not to lived for others?

Cheers to Terri, who has lived her life to help her family fulfil theirs. May eternal light shine upon her, as we pray and act for the end of euthanasia.

Drug trial gone wrong

Clinical Trials: "A nation of guinea pigs"

This reminds me of the story of Constant Gardener... Much as this clinical trial is necessary, it is sad when people sign up for clinical trials driven by economic need:

Patients in Sevagram are poor enough that the benefits of taking part in the study would amount to a health care windfall.

Bioethics Forum 2006: Prenatal Testing


I found out about Bioethics Forum from Dr Ignacio Segarra. He spoke of issues in bioethics using natural law framework with strong Catholic flavor. If any of you reading this are in Singapore, do attend the forum's first session of the year.
