Proton Magnetic Resonance Spectroscopy and MRI Reveal No Evidence for Brain Mitochondrial Dysfunction in Children with Autism Spectrum Disorder.

16 Mar

A study published today looks for mitochondrial dysfunction in autistic children. In specific, the researchers are looking directly at the brains of autistic children. The team, from the University of Washington, used both MRI (Magnetic Resonance Imaging) and proton magnetic resonance spectroscropic imaging (HRMS). MRI gives structural information on soft tissues. HMRS is a “spectroscopic” techinque: it gives chemical information on
Here’s a good reference with a discussion of HMRS on brain tissue (as a spectroscopy, not an imaging technique): Quantitative neuropathology by high resolution magic angle spinning proton magnetic resonance spectroscopy

With that background in hand, here is the abstract from the recent study on autism:

Abstract

Brain mitochondrial dysfunction has been proposed as an etiologic factor in autism spectrum disorder (ASD). Proton magnetic resonance spectroscopic imaging ((1)HMRS) and MRI were used to assess for evidence of brain mitochondrial dysfunction in longitudinal samples of children with ASD or developmental delay (DD), and cross-sectionally in typically developing (TD) children at 3-4, 6-7 and 9-10 years-of-age. A total of 239 studies from 130 unique participants (54ASD, 22DD, 54TD) were acquired. (1)HMRS and MRI revealed no evidence for brain mitochondrial dysfunction in the children with ASD. Findings do not support a substantive role for brain mitochondrial abnormalities in the etiology or symptom expression of ASD, nor the widespread use of hyperbaric oxygen treatment that has been advocated on the basis of this proposed relationship.

Does this mean that mitochondrial dysfunction never occurs in autistics? No. But it makes it very unlikely that more than a fraction of autistics have mitochondrial dysfunction in their brains.

Beyond that, the use of spectroscopic imaging is very impressive to me. MRI structural data is quite valuable on its own, but adding chemical information is very powerful.

The Urgent Next Step in the Fight to Save the Lanterman Act

16 Mar

The Arc and United Cerebral Palsy of California have put out an urgent action alert for residents of California. And by urgent they mean now. Their is a meeting at 1pm that they want to impact (<5 hours from when this was published).

Dear Friends,

Our community’s overwhelming turnout in the Capitol and numerous calls and visits to legislators, asking them to save the Lanterman Act, paid off. The Legislature so far has rejected most of the developmental services service cuts that the Brown administration proposed.

But the fight continues. We need your advocacy again — this morning.

Here’s where we stand. The Legislature’s budget committees, with both Democrats and Republicans voting for us, reduced the size of the cut to community services for people with developmental disabilities by $386 million. But that leaves $147 million in cuts that have to come from someplace.

The administration wants the $147 million to come from purchase-of-service “standards,” or “best practices” as the Legislature has started calling them. Either way sound good, but what they really mean is that arbitrary limits and not IPPs and IFSPs would determine what services people with disabilities receive.

The Legislature is set to meet at 1 p.m. today to vote on the state budget and bills to cut spending to balance the budget. One of the bills, AB 98, would direct the administration (specially, the Department of Developmental Services) to develop “best practices” and recommend them to the Legislature by May 15. There are two calls I’m asking you to make before then help head off that threat — one to each of you two local state legislators, your state senator and assembly member.

If you don’t know who they are, go to http://capwiz.com/thearc/state/main/?state=CA&view=myofficials , enter your ZIP code, scroll down to “state senators” and “state representatives,” and click on their names.

If you already have talked to staff members in your legislators’ local or Capitol offices, call those staff members again. Otherwise, call their Capitol offices.

Here is what you might say to each of them

1. Ask to talk to someone about the development services budget.
2. Write down the staff member’s name.
3. Introduce yourself, give them you address, and tell them why you care. For example, if you’re the parent of someone with a developmental disability, say so.
4. Tell them that you are against Section 1 of Assembly Bill 98, the developmental services budget “trailer bill” (they’ll know what that means). That’s the section about “best practices.” Ask that the legislator try to get it removed from the bill.
5. Even more important, whether or not Section 1 stays in the bill, ask the legislator to make a statement when the bill comes up for discussion today. Ask that the legislator say, when the Department of Developmental Services presents its recommendations for “best practices to the Legislature on May 15, the Legislature should consider the community organizations’ alternatives for ways to make savings in the budget while doing less damage that the administration’s recommendations would do. The idea is serve notice now that the Legislature will consider our community’s recommendations equally with the administration’s.

I know this is complicated. I wish I could make it simpler. I think that, if you stick to the five things I’ve suggested, your legislators will get the message. God knows we’re been working hard enough here in Sacramento to get it to them since the Assembly Bill 98 came out yesterday.

If you want to read the bill for yourself, go to www.leginfo.ca.gov/pub/11-12/bill/asm/ab_0051-0100/ab_98_bill_20110314_amended_sen_v98.html . Section 1 starts on page 5.

Thank you for your advocacy.

Legislator Who Suggested Siberia For ‘Retarded’ Resigns

15 Mar

Legislator Who Suggested Siberia For ‘Retarded’ Resigns is a piece on Disability Scoop. Yes, it is as bad as it sounds. Here’s a quote:

Rep. Martin Harty, a 91-year-old first-term Republican in the state’s House of Representatives, drew fire after it became public that he told a constituent that “the world is too populated” with “too many defective people.”

“I wish we had a Siberia so we could ship them all off to freeze to death and die and clean up the population,” Harty continued, according to the constituent’s account. He specified that he was referring to “the mentally ill, the retarded, people with physical disabilities and drug addictions.”

Take a read of the piece at Disability Scoop. Then take a few minutes to let your blood stop boiling before commenting here. Reading around for more on this story, I stumbled across these comments on the story from some of our “friends” over at another blog:

What the heck is a 91 year old doing as a ‘state legislator’? He sounds like an incipient Altzheimer’s case!!

and

Maybe the 90 year old lawmaker should step his grumpy ass down, and let someone with better hearing take his place. I hate to put it that way, but this is unacceptable behavior in office. I don’t care WHAT he did in WW2.

Do me a favor. If you want to make fun of this guy by bashing his real or perceived disabilities…don’t.

LeftBrain/RightBrain shame Age of Autism into half-hearted apology for gun violence

14 Mar

Via Facebook of course, not on their actual site:

Funny thing though, I would’ve thought that to be included in an image archive entitled ‘Fan pics _from_ Age of Autism’ it would’ve had to have been approved _by_ Age of Autism..?

Also note the lack of apology for the rampant anti-vaccine part of the image – just the gun violence. Age of Autism fail to see that by promoting an anti-vaccine message they are still condoning violence – just a different kind of violence.

At State-Run Homes, Abuse and Impunity

14 Mar

So reads the title of a very disturbing piece in the New York Times. At State-Run Homes, Abuse and Impunity discusses problems with the group homes in New York.

Nearly 40 years after New York emptied its scandal-ridden warehouses for the developmentally disabled, the far-flung network of small group homes that replaced them operates with scant oversight and few consequences for employees who abuse the vulnerable population.

Not only is there abuse, but perpetrators are often not charged.

A New York Times investigation over the past year has found widespread problems in the more than 2,000 state-run homes. In hundreds of cases reviewed by The Times, employees who sexually abused, beat or taunted residents were rarely fired, even after repeated offenses, and in many cases, were simply transferred to other group homes run by the state.

Sounds like the stories of abuse by Priests in the Catholic Church in a way, doesn’t it? Abuser is uncovered and moved rather than fired or prosecuted.

The Times puts a good share of the blame for protecting the perpretrators on the uniion:

The state initiated termination proceedings in 129 of the cases reviewed but succeeded in just 30 of them, in large part because the workers’ union, the Civil Service Employees Association, aggressively resisted firings in almost every case. A few employees resigned, even though the state sought only suspensions.

The story is fairly long, and very saddening to say the least. While a difficult read, it is an important one.

Age of Autism threaten doctors and also make clear how anti-vaccine they are

12 Mar

On a Facebook page entitled ‘Fan photos from Age of Autism‘ you will find this (click for bigger):

Lets not kid around here, this is a direct threat of violence towards people carrying ‘syringes’ i.e. people who might want to vaccinate children. I have no idea if Jenny McCarthy has any knowledge of this photo but its clear from the title ‘fan photos _from_ the Age of Autism, that Age of Autism clearly do.

Lets also be clear about the utterly anti-vaccine message of this image. The editors continually describe themselves as ‘pro-vaccine safety’. Let me suggest to them that creating a picture of Jenny McCarthy threatening people carrying syringes in a medical setting isn’t pro-vaccine safety. Its anti-vaccine pure and simple.

Reauthorizing the Combating Autism Act?

12 Mar

The Combating Autism Act (CAA) committed the US government to fund autism research. As part of this effort, the Interagency Autism Coordinating Committee (IACC) was re-authorized (it actually predated the CAA, having been established under the Children’s Health Act of 2000)

At the end of the last congress, a Combating Autism Reauthorization Act (CARA) was presented. It was a nice move by Sentator Dodd as he was retiring, but as you will read if you follow the link, that bill is dead:

This bill never became law. This bill was proposed in a previous session of Congress. Sessions of Congress last two years, and at the end of each session all proposed bills and resolutions that haven’t passed are cleared from the books. Members often reintroduce bills that did not come up for debate under a new number in the next session.

If you go to the Senate’s webpage and enter “autism” as a search term for current bills, you will get two. Neither is the re-authorization of the CAA. Similar results come from searching Thomas for autism.

Sometimes I think, I just can’t find it. But it really isn’t there. In their piece Urge Congress to Reintroduce the Combating Autism Reauthorization Act!, “The Child Health Site” is asking people to sign a petition to reintroduce CARA.

The text of the original CAA you will find the following (or similar) a number of times: Sunset.–This section shall not apply after September 30, 2011.

Authorization for funding will sunset this year. The IACC will sunset this year. That is, of course, unless a re-authorization occurs. I haven’t seen much from the national autism organizations calling for action on this. There is undoubtedly much going on behind the scenes, but it strikes this observer that perhaps something should have happened by now.

Funding Science in a Time of Austerity

12 Mar

Funding Science in a Time of Austerity is a blog post by Tom Insel, director of the National Institute of Mental Health (NIMH) in the US.

I’ve discussed many news stories of late which discuss special education in these tight fiscal times. Naturally research will be impacted as well. While the article by Tom Insel does not discuss autism specifically, it is worth a read. NIMH has not had a final appropriation from the government for this fiscal year (which started in Oct. 2010). And they are expecting cuts for fiscal year 2012.

Following is a post by Tom Insel, director of the NIMH:

C. S. Lewis once said that the “task of a modern educator is not to cut down jungles but to irrigate deserts.” The same might be said of an NIH institute today. But our ability to irrigate deserts may be compromised as we appear to be facing an austere funding future. As the Nation struggles to regain its economic footing, the final budgets for NIH in 2011 and 2012 remain uncertain. But there is little doubt that these will be tough years for NIMH funding.

Here is a quick synopsis. Following the doubling of the NIH budget from 1998-2003, NIMH has received budgets with sub-inflationary increases each year. By 2009, we had lost about 18 percent of our purchasing power relative to 2003, but through strategic cuts in awards, reductions in the out-years of multi-year grants, and elimination of programs, NIMH was able to maintain relatively stable funding throughout this period. By stable funding, I mean that we continued to support roughly 550 new research grants (R01 and R21-type grants) each year, representing at least 15 percent of proposals.

In 2009 and 2010, the American Recovery and Reinvestment Act (ARRA) brought a surge in funding to create jobs. With over $370M, NIMH was able to support several innovative projects, create or retain jobs, and fund some additional R01-type grants (for 2 years) on top of our regular appropriated budget. But this one-time surge from ARRA obscured the longer-term pattern of flat budgets that continued in 2009 and 2010 beneath the ARRA bubble. In 2010, the NIMH budget was 2.6 percent higher than 2009, still losing ground to inflation.

What about 2011? Although our budget year began October 1, 2010, we are still awaiting a final appropriation. Last week, Congress passed a continuing resolution until March 18, which means we will continue to operate under our 2010 budget rather than the President’s 2011 budget proposed last February. Prior to March 18th, Congress must vote either to extend the continuing resolution or to appropriate a budget for the remainder of the year. Both houses of Congress are concerned about the growing deficit and are committed to reining in spending, especially within the 12 percent of the budget labeled as “discretionary.” This will almost certainly mean a reduction in the NIH and NIMH budgets, but we do not know the extent of this reduction. The House voted for a $1.6B reduction below the 2010 NIH budget for 2011, including a 4.1 percent reduction (-$60M from 2010) for NIMH, but this budget still needs to be considered by the Senate.

In the absence of a final budget for this year and with expectations that we will likely see reductions in 2012, NIMH has been cautious about funding grants. We have a few principles that have guided us: prioritize research relevant to our strategic plan, support innovation, maximize the number of R01 grants, and protect early stage scientists. In support of these principles, we have reduced our intramural program, funded fewer centers, and reduced support of some large programs.

But even with these changes, the 2010 budget leaves us short in 2011. Partly because of the number of continuing grants and partly because of the increasing average cost of new awards, if we receive the full 2010 budget for 2011, we are projecting 481 new grants, representing roughly 10 percent of proposals. This would be the first time since 1999 that we would fund fewer than 500 new grants and would mark the lowest success rate in over 15 years. If the 2011 appropriation is 4.1 percent less than the 2010 budget, the actual number of new grants funded will likely be below 400.

Not surprisingly, this situation is creating anxiety in the scientific community. Basic scientists believe that the money has been shifted to translation. Clinical researchers say that funds are only going to basic science. But in fact, the Division of Neuroscience and Basic Behavioral Science, which was 27 percent of the total NIMH budget in 2005, was 29 percent in 2010 and will likely be close to this portion again in 2011.

Some have suggested that the funds are going to Centers or the intramural program instead of investigator-initiated R01 grants. But the percentage of R01s has only increased over the past decade.

A few scientists have suggested that the problem is a recent change in the review policy, allowing only a single re-submission. While this policy must seem catastrophic for someone who just missed the payline with a re-submitted grant, re-instating the “A2” would only delay funding for those within the payline. It may not increase the number of grants funded or the success rate.

For scientists, this may feel like a funding desert. During this relative drought, there may be many reasons for complaints. But the bottom line is that funds for new grants are the lowest we have seen in several years and the average costs of new grants is higher than ever ($419K in 2010 vs $313K in 2005). NIMH is committed to funding the highest impact science with the available funds. But as much as we would like to “irrigate the desert,” some outstanding science will, unfortunately, not get funded. And those projects selected for funding may receive less than optimal support.

What makes this desert especially difficult is that the scientific opportunities have never been better. We have unprecedented traction in the science necessary to make progress for helping people with mental illness. However, in this period of austerity, we will not at this time be able to fund some of the science that will make a difference for those in greatest need.

Mitochondrial Disease and Autism: Linked?

11 Mar

Mitochondrial disease and autism. I don’t read about it as much as during the peak of the Hannah Poling story, but it is a big topic. Emily Willingham at
Thinking Person’s Guide to Autism has put together an excellent post on the subject. Here’s the first paragraph:

Hannah Poling’s family entered the national spotlight when they revealed that Hannah’s autism-like symptoms may have been linked to a reaction to several childhood vaccines at once in combination with her mitochondrial dysfunction. Her case was not the first revelation of a possible mitochondrial disorder (MD)-autism spectrum disorder (ASD) link, but because of her ultimately successful vaccine injury suit, she became the avatar of the vaccines-cause-harm movement — which almost eclipsed the real scientific and therapeutic feature of her case: the mitochondria.

I’d love to do a wholesale copy of the post, but that’s hardly fair now, is it? So, I’ll send you all to the Thinking Person’s Guide to Autism and Mitochondrial Disease and Autism: Linked?
