Text of IOM Responses to Questions about Lack of Independent Analysis

Posted: February 5, 2012 at 4:54 pm


Here is the text of questions from the California Stem Cell Report and answers from the Institute of Medicine concerning its plans to secure independent perspectives during the IOM's examination of the California stem cell agency. So far, the IOM has not heard publicly from any independent sources.

Christine Stencel, a spokeswoman for the IOM, responded for the IOM. She first gave an overall statement. Then she answered the specific queries. We have inserted the questions from the California Stem Cell Report into her text  in order to make the Q&A easier to follow.

The IOM's general comment:

"The committee and staff are planning their next info gathering sessions. Specifics of these events haven't all been worked out yet, but one overall point is that the committee believes it is important to hear the full range of perspectives and experiences with CIRM and the committee members are actively pursuing sources of information that will allow them to adequately answer the questions they've been tasked to explore. The study is ongoing and there are still a lot of people and resources to tap and information to learn.

"To your specific questions:"

California Stem Cell Report:

"Does the IOM have plans to talk with or seek statements from such groups as the Little Hoover Commission and the Center for Genetics and Society or state Controller John Chiang?"

IOM response:

"Yes. And the committee is reading all the past reviews of CIRM."

California Stem Cell Report:

"Does the IOM plan to seek comments from grant applicants rejected by CIRM, particularly businesses? If so how many? How would such applicants be selected by the IOM for interviews or comments?"

IOM response:

"Yes, the committee wishes to hear these perspectives and is seeking ways to get them."

California Stem Cell Report:

"Does the IOM plan to do more than passively post forms for comment from others? Does it plan to email those forms, for example, to all CIRM grant recipients and applicants who were rejected? Does it plan to follow up to be sure an adequate response is generated?"

IOM response:

"The IOM is proactively working to get survey responses and encouraging people to respond."

California Stem Cell Report:

"What does the IOM mean by 'industry partners' on its (online) forms for comment?"

IOM response:

"Industry partners means CIRM investigators representing for-profit companies."

California Stem Cell Report:

"Does the IOM plan to examine both public and private complaints about conflicts of interest on the part of CIRM grant reviewers? By private, I mean written complaints to CIRM that the agency retains but has not made public."

IOM response:

"The committee is looking into the grants review process and working to make sure that the members obtain all relevant insights and information. The committee members intend to invite people who can provide a broad range of experiences with and perspectives of CIRM to the upcoming meeting in April."

The California Stem Cell Report later asked the IOM if it wanted to comment on a quote that we were considering using, which said,

"In the eyes of the IOM, scientists who draw funding from CIRM and other sources are 'independent.' They look at these things differently than regular people would."

The IOM responded,

"As to the quote you sent, as a response we would just reiterate that the committee is methodically going about its task and during the course of the study aims to gather the full range of information, experiences, and insights relevant to CIRM from a full range of sources."

Stem Cell Researchers 'Uneasy" in California

Posted: February 5, 2012 at 4:54 pm


The prestigious journal Nature today said that asking California voters for more billions for stem cell research in a few years "may strike residents as a luxury that they can ill afford."

The comment came in a piece by Erika Check Hayden dealing with the future of the California stem cell agency, which is expected to run out of money for new grants in about 2017. She wrote,

"Given that California is facing severe budget shortfalls, several billion dollars more for stem-cell science may strike residents as a luxury that they can ill afford. It may also prove difficult for CIRM’s supporters to point to any treatments that have emerged from the state’s investment. So far, the agency has funded only one clinical trial using embryonic stem cells, and that was halted by its sponsor, Geron of Menlo Park, California, last November.

"Yet the institute has spent just over $1 billion on new buildings and labs, basic research, training and translational research, often for projects that scientists say are crucial and would be difficult to get funded any other way. So the prospect of a future without CIRM is provoking unease. 'It would be a very different landscape if CIRM were not around,' says Howard Chang, a dermatologist and genome scientist at Stanford University in California."

Chang was a scheduled witness recently at a public meeting in California of the blue-ribbon Institute of Medicine panel examining the performance of the Golden State's $3 billion stem cell research effort. Chang is the recipient of $3.2 million in CIRM funding. Hayden wrote,

"Chang has a CIRM grant to examine epigenetics in human embryonic stem cells, and is part of another CIRM-funded team that is preparing a developmental regulatory protein for use as a regenerative therapy. Both projects would be difficult to continue without the agency, he says. Federal funding for research using human embryonic stem cells remains controversial, and could dry up altogether after the next presidential election (see Nature 481, 421–423; 2012). And neither of Chang’s other funders — the US National Institutes of Health (NIH) and the Howard Hughes Medical Institute in Chevy Chase, Maryland — supports his interdisciplinary translational work. Irina Conboy, a stem-cell engineer at the University of California, Berkeley, who draws half of her lab’s funding from CIRM, agrees that in supporting work that has specific clinical goals, the agency occupies a niche that will not easily be filled by basic-research funders. 'The NIH might say that the work does not have a strong theoretical component, so you’re not learning anything new,' she says."

Conboy was also a scheduled witness at the IOM hearing. She holds $2.2 million in CIRM grants.

Healthcare Prof:
The February edition of Neurosurgery reports that animal experiments in brain-injured rats have shown that stem cells injected via the carotid artery travel directly to the brain, greatly enhancing functional recovery. The study demonstrates, according to leading researcher Dr Toshiya Osanai, of Hokkaido University Graduate School of Medicine in Sapporo, Japan, that the carotid artery injection technique could, together with some form of in-vivo optical imaging to track the stem cells after transplantation, potentially be part of a new approach for stem cell transplantation in human brain trauma injuries (TBI).

Dr. Osanai and team assessed a new "intra-arterial" technique of stem cell transplantation in rats, with the aim of delivering the stem cells directly to the brain without having to go through the general circulation. They induced TBI in the animals before injecting stem cells into the carotid artery seven days later.

The stem cells were obtained from the rats' bone marrow and were labeled with "quantum dots" prior to being injected. Quantom dots are a biocompatible, fluorescent semiconductor created with nanotechnology that emit near-infrared light with much longer wavelengths that penetrate bone and skin, enabling a non-invasive method of monitoring the stem cells for a period of four weeks following transplantation.

This in vivo optical imaging technique enabled the scientists to observe that the injected stem cells entered the brain on the first attempt, without entering the general circulation. They observed that the stem cells started migrating from the capillaries into the injured part of the brain within three hours.

At week 4, the researchers noted that the rats in the stem cell transplant group achieved a substantial recovery of motor function, compared with the untreated animals that had no signs of recovery.

The team learnt, after examining the treated brains, that the stem cells had transformed into different brain cell types and aided in healing the injured brain area.

Over the last few years, the potential of stem cell therapy for curing and treating illnesses and conditions has been growing rapidly. Below is a list of some of its possible uses.

Stem cells represent a potential, new important method of treatment for those who suffered brain injuries, TBI and stroke. But even though bone marrow stem cells, similar to the ones used in the new study, are a promising source of donor cells, many questions remain open regarding the optimal timing, dose and route of stem cell delivery.

In the new animal study, the rats were injected with the stem cells one week after TBI. This is a "clinically relevant" time, given that this is the minimum time it takes to develop stem cells from bone marrow.

Transplanting the stem cells into the carotid artery is a fairly simple procedure that delivers the cells directly to the brain.

The experiments have also provided key evidence that stem cell treatment can promote healing after TBI with a substantial recovery of function.

Dr. Osanai and team write that by using in vivo optical imaging:

"The present study was the first to successfully track donor cells that were intra-arterially transplanted into the brain of living animals over four weeks."

A similar form of imaging technology could also prove beneficial for monitoring the effects of stem cell transplantation in humans, although the tracking will pose challenges, due to the human skull and scalp being much thicker than in rats.

The researchers conclude:

"Further studies are warranted to apply in vivo
optical imaging clinically."

New era of medicine in the offing, says scientist

Posted: February 4, 2012 at 11:01 pm

Renowned Japanese scientist Shinya Yamanaka, who achieved a major breakthrough in the emerging area of stem cell research by creating a possible alternative to embryonic stem cells in 2007, expressed confidence here on Friday that drugs would be available soon for diseases for which therapies are yet to be found.

Delivering a lecture on “New Era of Medicine with iPS Cells” organised jointly by Cell Press and TNQ Books and Journals, Prof. Yamanaka said the cells -- “induced pluripotent stem cells [iPS Cells]'' -- developed by him and his team would not only help overcome the ethical issues surrounding use of embryonic stem cells for treatment of diseases like spinal cord injuries, Type I diabetes or macular diseases but also help in development of drugs for conditions like motor neuron disease.

Embryonic stem cell therapy is considered important as it offers immense possibilities for treatment of a wide range of diseases and conditions since the cells proliferaterapidly and are pluripotent or possess the capability to differentiate into any type of cell, said Prof. Yamanaka. But it suffers from a major ethical issue as it involves use of live human embryos, Prof. Yamanaka pointed out. He said if there was a post-transplant rejection, they cannot be used from the patient's own cell.The iPS cells, on the other hand, are created from adult skin cells and do not have these two problems, while at the same time they provide for rapid proliferation and the possibility to differentiate into any type of cell, he said. Prof. Yamanaka and his team generated iPS mouse cells in 2006 and followed up with iPS cells developed from human skin cells in 2007.

Speaking about the potentials of iPS cells, he said studies using the cells for treatment of spinal cord injuries have already shown good results in mouse and monkey specimens and in two to three years scientists would be ready to go in for clinical trials. He, however, admitted that there are several challenges before the new technology. Its safety is yet to be proved completely and the process of deriving patient-specific iPS cells is time-consuming and expensive.

He expressed hope that scientists who are working on itwould overcome the challenges and a new era in medical treatment would emerge soon.

Union Human Resource Development Minister Kapil Sibal, who introduced him, said his Ministry along with the Ministries of Health and Science & Technology would take steps for Indian scientists to collaborate with him.

TNQ Books and Journals Managing Director Mariam Ram and Cell Press Executive Editor Emilie Marcus also spoke.

Institutes submit papers for stem cell conference

Posted: February 4, 2012 at 11:01 pm

More than 250 participants, including key ethicists and scientists, will present their views on stem cell research and its ethics at the Qatar International Conference on Stem Cell Science and Policy due to take place in Doha this month.
More than 45 national, regional and international institutes have already submitted over 70 abstracts for the conference.
The abstracts examine the various challenges and opportunities that stem cell research presents, and include themes such as the therapeutic potential of stem cell research, the challenges presented by stem cell research in the context of the GCC region, the commercial applications of stem cell research, and one of the most important topics in the dialogue surrounding stem cell research – the ethics and its ramifications for stem cell guidelines and policies.
“This is a unique opportunity for Qatar Foundation to continue the open dialogue it has established through its partnership with James A Baker III Institute and the Qatar Faculty of Islamic Studies on ethics in stem cell research,” said Faisal Mohammed al-Suwaidi, president, research and development, at Qatar Foundation.
The conference is the culmination of a series of initiatives developed through this tripartite partnership to develop best ethical practice in stem cell research in Qatar and across the region, including workshops with religious scholars in 2009 and a public forum in May 2010.
“We want to raise awareness about Qatar’s developments in stem cell research; however, we also want to explore the ethical policy ramifications that come along with these developments. The conference will invite scientists, ethicists and policy makers across Qatar, the region and the world to address the issues surrounding stem cell research and develop policy recommendations that account for ethical, religious and cultural factors,” said Khaled al-Subai, director, research co-ordination and compliance, Qatar Foundation.

Hepatitis Research May Benefit From Stem Cells

Patient / Public: Healthcare Prof:
Hepatitis C is a viral disease that leads to inflammation and organ failure. However, researchers are puzzled as to why some individuals are very susceptible to the disease, while others are not.

Researchers believe they could find out how genetic variations produce these different responses by investigating liver cells from different individuals in the lab. However, liver cells are hard to obtain and extremely challenging to grow in a lab dish as they often lose their normal function and structure when removed from the body.

Now, scientists from MIT, Rockefeller University and the Medical College of Wisconsin have found a technique to generate liver-like cells from induced pluripotent stem cells (iPSCs). iPSCs are created from body tissues instead of embryos; the liver-like cells that can be infected with hepatitis C. iPSCs could allow researchers to investigate why individuals respond differently to the disease. The study is published in the Proceedings of the National Academy of Sciences.

Although many research terms have tried to established an infection in cells obtained from iPSCs, this study is the first to have done so. In addition, the new technique could eventually facilitate "personalized medicine." Using tissues obtained from the patient being treated, doctors could test the effectiveness of various medications and customize a treatment for that individual patient.

This study is a joint effort between Sangeeta Bhatia, the John and Dorothy Wilson Professor of Health Sciences and Technology and Electrical Engineering and Computer Science at MIT; Charles Rice, a professor of virology at Rockefeller; and Stephen Duncan, a professor of human and molecular genetics at the Medical College of Wisconsin.

In 2011, Bhatia and Rice revealed that by growing liver cells on special micropatterned plates that direct their organization, they could influence the cells to grow outside the body. Although, these cells can be infected with hepatitis C, researchers cannot proactively research the role of genetic variation in viral responses, as the cells derive from organs donated for transplantation and represent only a small population.

Bhatia and Rice collaborated with Duncan, who had demonstrated that he could transform iPSCs into liver-like cells, in order to produce cells with more genetic variation.

Often, such iPSCs are taken from skin cells. Researchers can restore these cells to an immature state - the same as embryonic stem cells - which can differentiate into any cell type by switching on specific genes in those cells. The cells can then be directed, once they become pluripotent, to become liver-like cells by switching on genes that regulate liver development.

In this study, MIT postdoc Robert Schwartz and graduate student Kartik Trehan infected those liver-like cells with hepatitis C. They created the viruses to expel a light-producing protein each time they went through their life cycle in order to confirm that infection had taken place.

The primary goal for the team is to obtain cells from individuals who had unusual reactions to hepatitis C infection and transform them into liver cells in order to research their genetics to find out why they responded the way they did.

Bhatia explains:

"Hepatitis C virus causes an unusually robust infection in some people, while others are very good at clearing it. It's not yet known why those differences exist."

One possible reason may be genetic variations in the expression of immune molecules, such as interleukin-28, a protein that has been demonstrated to play a vital role in the response to hepatitis infection. Other potential factors include, cell's susceptibility to having viruses control their replication machinery and other cellular structures, as well as cell's expression of surface proteins that allow the virus to penetrate the cells.

Bhatia explains the liver-like cells generated in this investigation are similar to "late fetal" liver cells. The team is currently working on producing more mature liver cells.

The long-term goal for the team is personalized treatments for individuals with hepatitis. According to Bhatia one could imagine obtaining cells from an individual, making iPSCs, reprogramming them into liver cells and infecting them with the same strain of hepatitis that the individual has. This would allow doctors to test various medications on the cells to find out which ones are better at clearing the infection.

Molecules to Medicine: Plan B: The Tradition of Politics at the FDA

Posted: February 4, 2012 at 10:14 am

Morning After The Morning's Trash

In my last post, I focused on flaws in the medical device approval process. The Union of Concerned Scientists’ “FDA at a Crossroads” meeting also covered problems with drug approval. This is perhaps no better illustrated than by the disappointing decision by Secretary of Health Kathleen Sebelius’ to deny the emergency contraceptive, Plan B, over-the-counter status for women under the age of 17. This was a particular disappointment to many because President Obama had promised that decisions at the FDA would be made based on science, rather than politics. Some of us, naively, hoped that “change we can believe in” was real, having forgotten that the Tooth Fairy wasn’t.

Two of the speakers at the recent FDA at a Crossroads meeting were formerly at the FDA; both left because of political pressures. Dr. David Ross, was an FDA reviewer for Ketek (an antibiotic). In a Congressional hearing, Dr. Ross testified that he had been pressured to soften his findings about liver toxicity due to the drug and threatened by FDA Commissioner von Eschenbach, who said, “If you don’t follow the team, if you don’t do what you’re supposed to do, the first time you’ll be spoken to, the second time you’ll be benched, and the third time, you’ll be traded,” according to Ross.

The other was Dr. Susan Wood, former assistant FDA commissioner for women’s health and director of the Office of Women’s Health, who resigned from the FDA after Plan B’s approval was initially denied.

The Tradition of Politics at the FDA

Before we delve into the specific discussion of Plan B, let’s look at the context of the politicization of the FDA, under the recent Bush administration in particular, which led to the characterization of the “broken FDA.” During that period access to healthcare information, health services, and medical research became limited by two growing trends: the infusion of increasingly restrictive religious doctrines and the implementation of ideology-driven—rather than scientific, evidence-based—public policies. Initially, access to science-based information was limited through censorship and even distortion in government sources (e.g., data regarding the efficacy of condoms in preventing HIV infections and STDs were removed from the CDC’s Web site). This neither helped reduce the teen birthrate nor STDs. They used the same misinformation tactic with the now discredited breast cancer-abortion link.

Ideologic shifts were also demonstrated by resource allocations. For example, HIV prevention programs at the CDC were reduced by $4 million while funding for abstinence-only programs rose from $20 million to $167 million, despite the lack of evidence of effectiveness, in contrast to the previous peer-review, scientific-merit-based process of NIH grant funding. No federal money is spent on comprehensive sex education. Even worse, since 1982, “Over $1 billion in government funding has been granted to abstinence-only programs…[which] are expressly forbidden from discussing contraception…and often contain factually inaccurate and distorted information. Those who design and operate these programs are often inexperienced, religiously-motivated and frequently have close ties to the anti-abortion movement.”

The trend away from evidence-based medicine affects healthcare practitioners in numerous areas, ranging from patient education and disturbingly eroding standards of medical care to selection of research topics, grant writing, and the research funding process. Upon her dismissal from the President’s Council on Bioethics in 2004 for disagreeing with the administration’s stance on stem cell research, Dr. Elizabeth Blackburn, a prominent cancer researcher and one of only three full-time biomedical researchers on the council, wrote, “When prominent scientists must fear that descriptions of their research will be misrepresented and misused by their government to advance political ends, something is deeply wrong.” Among her many honors, incidentally, is the 2009 Nobel Prize in Medicine.

A brief history of the FDA commissioners and other key persons over the past 20 years illustrates politics at work in the FDA.

David Kessler (commissioner,1990–1997) took a great deal of heat for trying to have the FDA regulate tobacco products and for trying to gain approval for RU-486 (mifepristone).(He lost on both counts.) He was also notable for being appointed by President George H. W. Bush and retained by President Clinton.

Jane Henney (commissioner, 1998–2001), also appointed by Clinton, authorized FDA approval of RU-486. She was, not surprisingly, ousted when George W. Bush took office. She also tried to change business as usual by filling positions with career appointees rather than political ones, actively demonstrating her goal of “leading policy and making enforcement decisions based on science, not on political whims.”

An infamous nominee for chairing Bush’s FDA advisory panel on women’s health policy was Dr. W. David Hager, an obstetrician-gynecologist. He had helped prepare a “citizens’ petition” calling for the FDA to reverse its approval of RU-486. He was perhaps more widely known for his reported refusal to prescribe contraceptives to married women and as author of a book that “recommends specific Scripture readings and prayers for such ailments as headaches and premenstrual syndrome.” After the outcry of critics, he was not appointed chair of the advisory panel but did serve on it in 2002–2005, despite bipartisan opposition.

Mark McClellan (commissioner, 2002–2004) was an economist appointed by George W. Bush. McClellan reportedly had decided against approving Plan B for emergency contraception even before his staff completed its analysis.

Lester Crawford (commissioner, July–September 2005) was a veterinarian also appointed by George W. Bush. His term is perhaps best remembered for three features: the audacity of a veterinarian making decisions about women’s health and reproduction, his vehement opposition to Plan B’s approval, and the criminal charges against him for false reporting about holdings relevant to his appointment (that he and his wife owned stocks in food, beverage, and medical device companies that he was in charge of regulating). He got off with probation and a fine.

Susan F. Wood was another casualty of Crawford’s brief and divisive tenure at the FDA. As noted, she resigned because of the politicization of the agency—specifically, having the approval of Plan B emergency contraception denied, despite scientific evidence of the pill’s safety and recommendations from the FDA’s own advisory committee.

Andrew C. von Eschenbach (commissioner, 2005–2009) had been the head of the National Cancer Institute before being appointed as FDA commissioner. He was also tied to the decision of the FDA to deny emergency contraceptives over-the-counter status, despite the recommendation of the FDA’s advisory group and its own staff members, as well as that of many medical organizations.17 The FDA had followed advisory committee recommendations in every other case in the past decade. He is also known for reportedly threatening FDA reviewers who disagreed with him. Von Eschenbach’s ideologic, rather than evidence- based, decisions were so egregious that on March 23, 2009, the U.S. District Court (Tummino v. Torti) ordered the FDA to reconsider its decision blocking access to Plan B. It also ordered the FDA to act within 30 days to extend over-the-counter access to 17-year-olds. The court’s conclusions about the FDA’s behavior were damning.

The FDA’s ability to function and its reputation have been seriously hurt in the past decade. In a 2006 survey of FDA scientists, about 18 percent responded that they had been asked to exclude or alter information or their report’s conclusions for nonscientific reasons. A further 60 percent were aware of cases where industry “inappropriately induced or attempted to induce the reversal, withdrawal or modification of FDA determinations or actions.” One-fifth (20 percent) said they had been “asked explicitly by FDA decision makers to provide incomplete, inaccurate or misleading information to the public, regulated industry, media, or elected/senior government officials.” Lest you think this survey was markedly biased, even Senator Chuck Grassley, a staunch Republican, commented on the survey report, “The responses of these scientists reinforce the findings of the independent Government Accountability Office, which said the process for reviewing drugs on the market is deeply flawed.”

As a result of the politicization, the FDA staff has reportedly become greatly demoralized, interfering with its ability to function and protect the public. FDA whistle-blowers have testified that the agency considers the drug companies its clients, and its decision-making furthers the interests of those clients.

Many experienced and valuable clinicians have left the agency, leaving a void. Equally importantly, the FDA has lost considerable respect and authority in the eyes of both the public and important members of Congress.

From 2001 to 2009, the most obvious politicization at the FDA was related to women’s health issues, and especially access to contraception.

In March 2009, President Obama issued a memorandum on scientific integrity. A further encouraging sign of change was the May 2009 appointment of two well-respected physicians to lead the FDA, Drs. Margaret Hamburg and Joshua Sharfstein. Dr. Sharfstein has since left. Dr. Hamburg, the opening speaker at the UCS conference, noted that it was imperative to build trust in FDA’s integrity, and that it is science-based. Dr. Hamburg concluded that “I agree with the Center [for Drug Evaluation and Research (CDER)] that there is adequate and reasonable, well-supported, and science-based evidence that Plan B One-Step is safe and effective and should be approved for nonprescription use for all females of child-bearing potential.”

Unfortunately, Dr. Hamburg—and all women—just had the rug pulled out from them by Sebelius’ overtly political, evidence-be-damned stance.

Plan B Perspective

The irrational decision to overrule the recommendation of numerous experts appears based on the idea that young girls would be buying the pill without parental consent, and that such girls could not do so safely. They ignore that kids can readily buy Tylenol, which has significant liver toxicity and is often a component of deadly drug overdoses. Plan B is far safer—and also unlikely to be used routinely because, at ~$50, it is relatively expensive.

Even the conservative American Academy of Pediatrics urged approval of the morning-after pill for young teens, recognizing Plan B as being a safer alternative to abortions or unwanted pregnancies.

Plan B has the same hormone found in birth control pills, progestin, but in a larger dose. It works primarily by preventing ovulation. In contrast, mifepristone, or RU-486, is used to induce a medical abortion in a process similar to a miscarriage.

What were the arguments against Plan B this time? President Obama expressed his concern as a parent, that his daughters must not have access to such a medicine without adult guidance. His personal preferences are not “evidence-based science”. And he is deluding himself. We can guide our children, but we cannot control their behavior. My hope has been to educate my kids and offer them counsel knowing that, for better or worse, they will make many mistakes along the way. Prevention of pregnancy through ready access to contraceptives is far safer than an abortion or unwanted pregnancy. . .which may doom a teen to a lifetime of poverty and misery. There is a superb cartoon capturing the debate, Matt Davies,’ “Which of these responsibilities is a 15 year old too young to be handed?”—a screaming baby or Plan B pill.

Even the digital world seems to be biased, as now even Siri is getting into the act. Siri conveniently can direct you where to buy Viagra, but feigns ignorance when asked to direct to a reproductive health center offering abortion counseling or services.

The Plan B Decision has been characterized as “Sacrificing ‘Change We Can Believe In’ for Expediency?” “Only half of the nation’s teen moms ever earn a diploma; more than half go on welfare; and more than half of the families started by teens live in poverty.” The Ft. Wayne paper has it right stating, “Plan B politics ignore human toll.” I have never understood how many conservatives can demand censorship, restriction of contraceptives, and control of women’s bodies, all in the name of being “pro-life.” Fetal rights trump a woman’s…but then these people take no responsibility for the care, feeding, and education of these unwanted children. The sanctity of life ends at the womb. A life sentence is a huge price for a moment’s mistake.

Mechai Viravaidya

Even Thailand, which many US citizens likely would (erroneously) consider to be a third-world country, is more enlightened in some health-related ways. For example, Mechai Viravaidya, a former Thai senator and founder of the Population and Community Development Association (PDA), and enormously successful family planning NGO, made a brilliant educational campaign focused on reducing both the birthrate and the AIDS epidemic, by making sex education fun and promoting condoms to be as readily available as cabbages. He even has a restaurant and resort known as “Cabbages and Condoms.” It was a wonderful place to visit. (insert pic)

So why did Obama and Sebelius kill OTC Plan B—the first time that the Health and Human Services Commission has ever overruled the FDA? Only two reasons come to mind. The first is that Obama is overtly campaigning for the conservative vote. The second is similar, but a bit less overt—that OTC Plan B was sacrificed to take a firmer stance on having contraceptive coverage as part of all insurance plans.

And Plan B’s got it right, too, in their ad: “I chose a condom but it broke. Now I Have A Second Chance.”

Why don’t the politicians get it?
