Swine Flu: The Next SARS Virus?
The existing logic for such a sensational story is the fact that there are so many methods of contracting such a highly contagious disease in today’s fast-paced society that a real pandemic is very likely. Examples of this include the outcry of the SARS virus and the avian bird flu. These diseases can travel with airplane travelers to the most distant parts of the globe, and strike the population when least expected. A new virus that is little known about will strike even more swiftly because there is no existing contingency plan in place.
While I believe that these are very real threats, I also know that the media has a tendency to blow up affairs regarding various new diseases; emphasis is placed on the sensation factor rather than actual extent of impact on society. It’s a business, and simple medical articles and affairs need to have a doomsday appeal to them if views are to be generated. While SARS and the avian flu remain very real and infectious, comments about them have faded away; they never evolved into the earth-shattering plagues that we were led to believe. So take the latest news about the swine flu with a grain of salt: it might be a very real threat, but just don’t regard as the next Spanish Influenza of 1918.

Crazy Talk
This person, a blogger posting to the “UK Coalition,” is suggesting that we apply Darwinian natural selection to those living in and suffering from HIV/AIDS in Africa. He say’s “shouldn't we let people die until only those with a greater resistance to the disease emerge?” He argues that through the current care that is provided to African populations with HIV/AIDS, does not cure them but rather lets them live so that they can continue to spread it “through ignorance.” After this statement he cites the tragic yet true problem that some Africans believe that sleeping with a virgin will cure their HIV/AIDS, which according to a Reuters’ article has vastly increased incidence of rape. This piece of evidence simply shows the additional level of commitment that the world still owes Africa. As mentioned in the Reuters article, simple education programs in Africa appear to have dispelled this belief in younger age groups. What comes through most is that to follow through with this plan of action proposed by the blogger would mean the avoidable death and suffering of millions of Africans. How this blogger thought this fact could be avoided escapes me…
Should we be concerned with the undermining spread of such an unethical argument? Is there any legitimate worry that such dangerous logic will spread enough to undermine the relief effort in anyway? I would answer my own question and say, “probably not,” but still, the very existence of such publicly projected thoughts worries me…

What is So Wrong about a DNA Database?
But is this really such an egregious encroachment on the privacy and civil liberties of blameless citizens? The database would be used solely to solve crimes (but of course, this is assuming that you trust the F.B.I. to use the information as it says it will, which is another matter entirely). An innocent, law-abiding citizen can feel confident that his or her DNA will not show up as a “crime scene sample,” so his or her DNA profile will never be used for anything. Isn’t it worth sacrificing a tiny bit of privacy to help the investigation of horrific crimes go more quickly and smoothly? Isn’t expediting the identification and capture of dangerous criminals a worthwhile goal? Wouldn’t this prevent further harm to others, as well as allow crime victims and their families to begin to heal as soon as possible?

Pushing the ethical limits of embryonic stem cell research
This change frees up significantly the amount of leeway researchers have in investigating potentially life-saving technologies, which will have invaluable benefits in the long run. More than 760 current lines could be funded under the new guidelines, which will undoubtedly speed progress. Opponents of stem cell research are unsuprisingly decrying the new developments, but interesting to note is the discontent some proponents for research are making known.
Proponents acknowledge that these changes are certainly a step in the right direction, but some do not think it is enough. They want embryo lines created from "research" embryos, not only IVF embryos, to be OK'd as well. They claim that specific cell lines will not be able to be generated with the current limitations.
I personally think NIH's changes are enough, at least for now. It is already an extraordinary compromise for both sides to limit research to discarded cells that would otherwise be destroyed, versus creating cells for the explicit sake of destroying them for research. Stem cell research is still a new science, and ethical constraints are sure to slacken in the coming years, so it will be a slow process. The argument that specific cell lines won't be able to come to fruition is a little questionable to me, because I don't really think the science is at a point where embryos can be picked for specific "stem cell" purposes. To work with what is already available (and there is PLENTY available) is already fine by my book.

A Pressing Problem for Harvard
In fact, the American Medical Student Association gave Harvard an F in terms of how they over watch drug industry money. The grading process is a great idea, but there should be more done. One idea is to set up a punishment system in order to prevent further transgressions. So far, no official entity regulates the flow of money; this must corrected. This will not prove easy, as the recent economic downturn sapped endowment returns and potential benefactors shy away. However, this is a question of fundamental ethics, and the right thing to do is obvious.
Mother vs. Fetus: Epilepsy vs. I.Q.
Amidst these findings, a few other issues concerning this study surfaced. Can I.Q. points really reflect accurately the cognitive abilities of these children born from valpropate-using mothers? How should the physician prioritize the interest of his two patients: the mother and the fetus? But more importantly, was it ethical for the researchers to study pregnant women using valpropate versus other antiseizure medications when it is previously known that they may cause developmental harm to the fetus?

Natural Bone Marrow Regeneration?
In addition to simply marrow replenishment, the technique also has other implications for organ recipients. Normally, organ transplants are complicated by the possibility of harmful reactions towards the transplanted organs, and must therefore take medication to suppress the effects. Furthermore, since the transplanted organs are generally permanent, the negative effects could remain for the rest of their lives. However, mouse studies exist that suggest bone marrow transplants could prevent rejection against organs. The immune system cells created by the bone marrow are responsible for these reactions. Thus, marrow transplants could eventually result in acceptance of the organ as one of the body’s own.
I feel that this research is a remarkable development. This technique seems as if it is both easy and inexpensive, two qualities which I think are necessary for it to become a widespread treatment. As such, I am eager to read more about its success on direct marrow regeneration. My only question is about the time frame mentioned. Why should it take a few years to be implemented as mentioned in the article? If the cells are indeed from the person’s own culture, what remains to be so extensively tested?

Is Infanticide Such A Crime?
Yet the issue of infanticide has arisen yet as a byproduct of the current debate on euthanasia and physician-assisted suicide. In some ways, it is even more controversial compared to euthanasia and PAS, because it is not the individual making the choice; rather, the power lies with the parents or legal guardians of the infant. Personal choice is thus thrown out the window. I personally think that it is best to trust the parent’s judgment as long as it is in reason. Despite the ethical problems this entails, there is little doubt that no one knows that personal whims and wishes of a suffering child better than his or her parents. The courts seem to agree with me on this. Recently, a Dutch physician, Dr. Eduard Verhagen, was brought to trial for the mercy killing of four babies after he was given parental permission. Although, his actions were illegal under Dutch law, he hasn’t been prosecuted by for the court for them. To me, this demonstrates the acceptance of an imperfect but most suitable system.

The Misguided Quest for Childhood Beauty
The ethical issue behind these cosmetic surgeries performed on youth is the fact that parents are the ones giving consent to this surgery, even though their children are still in the developmental process. Undergoing these procedures at such a young and vulnerable age limits the children’s autonomy by taking away their right to make a decision that should really be made later on when they are adults. Not only are these procedures going against nature, but moreover, cosmetic surgery is meant for those who have developed fully and who have made the personal decision to change an aspect of their appearance.
In effect, parents giving consent to their children going under the knife to improve their looks places too high of a value on beauty and perfection in the youngest members of our society. We need to place a higher value on children and their natural development into healthy adults, rather than attempt to perfect them physically before they have had a chance to determine for themselves what aspects of their appearance they desire to change.
The article touches on the controversial issue that parents of children with gender identity disorder face when deciding whether to intervene with psychotherapy or accommodate the gender with which their child identifies by allowing them to undergo surgery for the cooresponding male or female characteristics. Although I agree that this issue is one of the most sensitive involving cosmetic surgery, I think that they more important question we should ask is whether we need to do anything at all at such a young age in a child’s development. Though developing in a body that one feels is not the correct gender may be somewhat of a traumatic experience, I feel that parents should provide support to their child by nurturing them just as they would any other child. In this way, once these children reach adulthood and can make decisions for themselves, they have the autonomy to decide whether they want to undergo gender changes. Above all, parents should not be making decisions for non-medical cosmetic surgery for their children, but rather should be loving and supporting in the natural development processes of their child in order to raise a child who is confident and has a good sense of his or her internal and external beauty.

What Will His Life Look Like?
When Nikolas Evans unexpectedly died in a fight, he left behind a mother and a spoken desire to have children. In the past, this event would simply be tragic. Now, however, because of modern technology, the situation has become ethically complicated. Evans' mother has a new option that she has chosen to use: harvesting her dead son's sperm and using it to fulfill his wish of having a child. The ethical issues here are profound, ranging from whether Nikolas would have wanted to have a child posthumously to the lack of time available for the grieving mother to reconsider her choice: sperm must be collected from the dead body soon after the passing of the future father.
However, the issue that struck me most was one brought up by Tom Mayo, director of Southern Methodist University's Maguire Center for Ethics and Public Responsibility. "That child's biological father will be dead. The mother may be an egg donor, anonymous or gestational surrogate...This is a tough way for a kid to come into the world. As the details emerge and the child learns more about their origins, I just wonder what the impact will be on a replacement child."
Is this a legitimate ethical issue to raise? Can we really decide whether or not to bring a child into the world on the basis of speculation about what his life will be like? On the one hand, it seems wrong to bring a child into the world unnaturally when it is entirely possible that the child's life will not be optimal. On the other hand, it seems paternalistic to make a decision as large as whether or not another human being should exist based on one's own personal views about the potential of their future life. Should we really assess the quality of a future child's life every time somebody wants to conceive a child through nontraditional means?

The Stork’s Dilemma: To whom should life be brought?
Kaylee was born with an extremely rare brain condition known as Joubert syndrome. Kaylee’s brain stem is not and will not completely develop, because of this she is now incapable of breathing on her own – she must be attached to a breathing machine in order to survive. At one point her natural breathing stopped 100 times an hour. Lilly on the other hand was born “with a congenital heart defect called truncus arteriosus and has been given only weeks to live.” Although Lilly will survive and may progress to be for the most part a completely healthy individual if she receives a heart transplant. Faced with no cure, no other options, and Kaylee’s eventual death her parents decided to remove her from life support and, upon her passing, have her heart donated to Lilly, who’s touching, compelling, and saddening story they had read about in a Toronto news paper (the Hospital where both babies are located is in Toronto). Kaylee’s parents took solace in the fact that the death of their daughter, which otherwise would have brought about nothing but remorse, would now be giving life and happiness to a family in a similar situation as their own.
Although the circumstances got increasingly more complicated, since initially the hospital would not qualify Kaylee as an appropriate donor. After public outcry the hospital reversed its decision and allowed the transplant to go through. But to add another even more complicating factor, after Kaylee was removed from her breathing apparatus she survived for more than an hour under her own power, again making her under hospital regulations ineligible as a donor.
Regardless of the twists and turns that have occurred here it is important to reflect on the ethics that are embedded within this story. Yes, Kaylee and Lilly’s situation is touching and emotionally powerful in its sympathetic appeal, but it should be noted that public outcry alone was sufficient to make the hospital overturn its original decision to not allow the transplant. This effectively overthrew the hospitals protocols, which are based on maintaining the greatest safety, efficacy, and benefit that a transplanted organ can bring. Ethically, if the public believed it was the right thing and demanded it, should that mean that the hospital should have folded its carefully constructed principles? Also in normal cases where organs are transplanted from the deceased, anonymity is maintained to avoid biased selection, by the donor, of who should receive the donated organ. It is believed that doctors should make that decision based on their ability to determine who the organ would best serve with the best chance of success. Although Kaylee and Lilly’s situation seems far from ethically troubling it does set a precedent for the biased selection of organ recipients, which has the potential for scarce organs to be distributed along lines of race, gender, religion, socio-economic status or education level instead of simply to those who have been determined to need them most.
Personally I would like to witness this stirring transplant occur, but these important matters of ethical precedents should at least be addressed, as it appears that they were entirely overlooked by all but one out of thirty of the articles that covered this story.

Corruption in Pharmaceutical Research
Dr. Joseph Biederman, a child psychiatry bigwig, is in the midst of a nasty conflict of interest investigation regarding his dealings with Johnson & Johnson. Biederman has wielded his “Olympian” influence for years to propound his pro-medication stance on psychiatric disorders in children. However, he neglected to report the vast majority of the millions of dollars in profits he earned while conducting clinical trials for the pharmaceutical company. Furthermore, it was recently revealed that he designed his trials with the express purpose of proving (rather than objectively determining) the effectiveness of the experimental drug.
Biederman’s obvious bias towards the welfare of the company that lines his pockets has resulted in his flagrant disregard for the basic principles of good science. The safety and efficacy of every antipsychotic drug whose success was facilitated by his work (and there have been many) is now under a dark “shadow” of doubt. The widespread pediatric use of these drugs—a policy that came into being largely as a result of Biederman’s championing—is now viewed with suspicion, raising the dreadful possibility that doctors may have been administering unnecessary or even harmful treatments to children as young as two.
But this issue has even broader implications. It serves to discredit biomedical research as a whole. The field is already associated with enough ethical controversy; this serious of a blow to its reputation is the last thing it needs.

Forget all about that MOL exam!
For those of you who couldn't be bothered with reading Professor Zwicker's email, here's a quick synopsis of the article from the NY Times. Basically scientists are on the verge of being able to surpress one's memory, logically of a traumatic and psychologically debiliating event. Controlling a molecule called PKMzeta, using the ZIP drug to surpress it, memory in mice was erased. And researchers contend that humans are not too far behind.
So what are the applications of such a treatment? Say you had some sort of horrible experience, and the memory of said experience limited your ability to carry out daily activities. Or you were addicted to some drug, and erasing the body's memory of taking said drug would cure your addiction. From this standpoint, the therapeutic benefits of memory wipes are clear, and frankly should be wholeheartedly pursued, as we've already discussed how therapy is relatively mild compared to "enhancement" and things of that nature.
Does memory determine who we are? Would I be the same if a terrible happening that altered who I was was wiped from my mind? The fact that such a mood-altering event is unnatural and not something you're inherently born with might argue no, but what of the events that make you a better person, that improve your outlook and general well-being? You weren't born with those, so should we wipe them out? But if we should use this argument, what of life-altering conditions such as cancer? Surely such an earth-shattering disease might have a large influence in a person's "being," but who would hesitate to eradicated it at first thought? In that, I think that "bad memories" can just be considered another disease to be cured.
There are concerns about the risks of multiple memories being inadvertently lost, or erasing memories of crimes or bad behavior, "blocking your conscience" in a way. But if this technology is used in a highly scrutinized and limited way, and is failproof, then I suppose we don't have to worry about these qualms, until we the true nature of memory wipes.
On the topic of conscience blocking, however, take for example a serial killer that repents, and then forgets his crimes. Arguably it wouldn't be right to absolve him or her from these weighty memories that form the moral conscience. But what of someone that accidentally killed a pedestrian while driving with poor visibility? Should he or she be able to wipe that memory, even if they were charged of manslaughter? Just some food for thought.

Seeing Isn’t Believing?
What is even more discomforting is that studies have suggested beta-blockers to act in the opposite direction compared to what they should theoretically be doing for our body. Instead of saving lives as intended, the beta-blockers “caused a definite increase in heart failure.” (NYT) Despite such opposing data, doctors had still prescribed beta-blockers after the study (NYT). Although, as of April 1, 2009, beta-blockers will no longer be a government advised form of treatment, this situation have sparked some interesting questions. As David Newman, writer for the New York Times article, asked, “ Can we handle what the evidence reveals? Are we ready for the truth?” But more realistically, are we willing to let go of what we have believed in for so long? Thus, what is the most troubling is the inconsistency between application and theoretical science. After all, much of today’s successful medical advancements work in accordance to scientific theories. If today’s theories could be replaced by study results, then these results could also be replaced in the future. How reliable scientific information are is still uncertain and thus study results also should not be emphasized more than theoretical science.
