Election Won: A Physician's Hope for the Future

Henry R. Black, MD

 Nov 08, 2012

Hi. I'm Dr. Henry Black. I'm a Clinical Professor of Internal Medicine at the New York Langone School of Medicine and a member of the Center for the Prevention of Cardiovascular Disease at that institution. Now that the election returns are just about in, it's fairly clear to me, at least, that the country has rejected much of the agenda of the Tea Party and much of the agenda of the Republicans, and it's certainly time for the Republicans to change their course or they will continue to be a minority party. It was very clear to me early on that relying just on white male voters was not going to win as this country shifted its focus and its demographics. This has been repeated many, many times by analysts and I think I'm just as qualified as some of them to be able to predict what's going to happen.

As far as the impact on physicians, I've always thought that having more insured people, even if they weren't paying as much as some doctors were used to getting, was going to end up improving things. One only needs to look back at the AMA's attempt to stop Medicare in the early 1960s to realize that when we were taking care of people and getting compensated for it, no matter who they were, that in the end this was going to help us, and that certainly is what happened. This time, the AMA actually endorsed the Affordable Care Act, and I think that was a wise thing.

Now, when that dust has cleared and some things are going to begin kicking in during 2014, it's time for hospitals and for doctors to readjust what they've been doing, and I suspect that they will. One thing this election clearly showed is that enormous amounts of money, maybe $2.5-6 billion in some estimates, aren't enough to sway people who have a different approach to what's going on.

I do think the fiscal cliff that we're concerned about is going to have to be dealt with or else it's going to happen. Like it or not, Bush tax cuts will disappear unless something is done, and the still-sitting Congress is going to have to deal with these issues, although they're probably going to kick the can down the road to the next Congress.

So with that in mind, what does it mean for doctors? It means that every patient that we see will be insured one way or another, maybe not for as much as we're used to getting, but they will be insured. It's going to change how clinicians are compensated, which will be more for cognitive issues than for procedures, and that, in my opinion, is a good thing. In some ways, the physicians who do procedures are now overpaid, and those who spend a similar amount of time in a cognitive way are going to be properly compensated. Right now we can look at what this means and how this has been interpreted.

I've always had faith that Axelrod and his group who figured out what to do in 2008 will have also figured out what to do in 2012. They've understood the pulse of the country, they've understood the major demographic shifts, and that people want to have insurance. The middle class has to improve, which seems to be an issue of the very wealthy making enormous amounts of money and the people in the middle and below losing money. This is going to change. As far as doctors go, let's go back and see our patients, let's take care of them, let's not worry so much about this, and let's move forward.

Election Lost: A Physician's Concerns for the Future

Frank J. Veith, MD

 Nov 09, 2012

The American people have spoken, and hopefully we, as a country, will go forward to prosperity and peace in the next 4 years. However, I have some concerns about the future well-being of the United States and American medicine. I believe the course that we've pursued over the last 4 years is not the correct one and is unsustainable. I worry particularly about our increasing debt, that we will continue to spend money that we don't have, that this will ultimately lead to the loss of our country's preeminence in the world and, ultimately, to its weakening and deterioration. Everything that we've seen points to the fact that the course we've been following for the last 4 years will be continued for the next 4 years, maybe even in an incremental fashion, and this will lead to the diminishment of the United States.

This is also true in regard to healthcare and the Affordable Care Act (ACA). As I've said and written before, I believe the main goals of the ACA are laudable. We should have some form of more widespread healthcare insurance and we must control healthcare costs. However, I do not believe that the ACA will accomplish either of these goals well. I believe the bill will lead to increased costs and, more importantly, that there are many components of the ACA -- some of which we're just finding out about -- that will be harmful. One example is the Sunshine Act, which will make effective collaboration between doctors and industry more difficult. Another is the moving of reimbursement for specialty care to primary care. I am not against paying primary care physicians more, but this increase should not come from decreased reimbursement to specialists whose hard and demanding work actually gets patients well. A third destructive component of the ACA is the punitive taxation on healthcare industries. This taxation will have many unintended negative consequences. I believe that all of these detrimental features of the ACA will not lead to improved healthcare for the American people. Rather, these features will harm American medicine and ultimately lead to worse care for the consumer, the public. Hopefully the ACA can be modified to fix these and as yet other unknown deficiencies, but I doubt that will happen. So, although the ACA's purposes are laudable, I have great concerns about the future of healthcare and our country. Hopefully I will be wrong and everything will come out right, but my judgment is that this won't happen in the next 4 years. I, therefore, have grave concerns about the future well-being of our country in general and healthcare in particular.

3.  More Evidence Early Intervention in Autism Gets Results.   

More Evidence Early Intervention in Autism Gets Results

Deborah Brauser

 Nov 13, 2012

An early behavioral intervention may not only improve behaviors in young children with autism but it could also lead to "striking" brain changes, according to new imaging research.

A small case series study showed that after receiving a pivotal response treatment (PRT) intervention, the participating children with autism spectrum disorders (ASD), who were only 5 years of age, showed significant improvements in adaptive behavior as well as in communication.

They also had increased activation in brain regions that support social perception, as shown by functional magnetic resonance imaging (fMRI) scans.

http://img.medscape.com/news/2012/ht_121114_fred_volkmar_120x156.jpg

Dr. Fred Volkmar

"I think this is the first time fMRI has been used to identify neural correlates of response to a treatment such as this. And parents really like it," coinvestigator Fred R. Volkmar, MD, director of the Child Study Center at the Yale University School of Medicine in New Haven, Connecticut, and chief of child psychiatry at the Children's Hospital at Yale–New Haven, told Medscape Medical News.

The study was published online October 27 in the Journal of Autism and Developmental Disorders.

Remarkable Changes

The PRT intervention includes parental training and uses motivational play activities in its methods. Although this initial analysis focused only on 2 children, Dr. Volkmar reported that the results have led to a new full-scale study that includes 60 children.

"For now, I wanted to get this information out there because I thought this was interesting and promising news," said Dr. Volkmar, adding that the findings represent a first step in a novel approach to individualized treatment planning.

"Autism research has come a long way. These findings are exciting because they show that early intervention works in autism. It's telling us that we're really making a difference."

"We've known that early intervention is important and that most children with autism — not all but most — get markedly better with good intervention," said Dr. Volkmar.

"We have truly seen over the past several decades really remarkable changes. Again, I do emphasize that not everyone gets better even with very good treatment, and we don't understand why. But on balance, kids are doing better," he said.

A recent multicenter study published in the November issue of the Journal of the American Academy of Child and Adolescent Psychiatry and reported by Medscape Medical News showed that young children with an ASD who received the Early Start Denver Model behavioral intervention had normalized patterns of brain activity in electroencephalographic measurements. They also had improved social behavior.

"This is another very good model, and they had similar results to ours. They had a larger sample, but they did not do an fMRI. But if you look at theirs and ours together, it's really encouraging in terms of being able to document progress," said Dr. Volkmar.

He added that there are "a number of models of good interventions" currently available for treating ASDs.

"And we're using them in younger and younger children because our detection methods are improving, as is public awareness," he said.

Play-Based Intervention

For this study, 2 5-year-old children (1 boy, 1 girl) with an ASD were assessed before and after receiving 4 months of the PRT intervention.

Developed at the University of California–Santa Barbara, this program "combines developmental aspects of learning and development, and is easy to implement in children younger than age two," according to a release.

"This targets behaviors that are very important to making developmental progress," added Dr. Volkmar.

http://img.medscape.com/news/2012/ht_121114_pam_ventola_120x156.jpg

Dr. Pamela Ventola

Coinvestigator Pamela Ventola, PhD, associate research scientist at the Yale Child Study Center and a clinical psychologist, noted that the researchers wanted to look at an intervention that could easily be made available to the community.

"This is something that can be used across the lifespan. But we found that it's an especially good fit for these preschool-aged and younger children because it's play-based. It's very natural, and it's fun for them," said Dr. Ventola.

At baseline, adaptive behavior was measured using the Vineland Adaptive Behavior Scales–II Survey Form, and language skills were measured using the Clinical Evaluation of Language Fundamentals, Fourth Edition. In addition, fMRI was used to measure neural response to social stimuli.

All measurements were repeated at the end of treatment.

Dramatic Improvement

Results demonstrated that both of the children showed significant improvement after receiving the intervention in pragmatic language, with the boy receiving a posttreatment score found in a range normally seen in typically developing children.

Both children also showed dramatic improvement in adaptive behavior skills, including receptive, written, play and leisure time, and coping. However, interpersonal relationship skills and personal daily living skills scores remained stable or even declined after treatment.

Nevertheless, the participants did have "increased activation to social stimuli in brain regions utilized by typically developing children," report the researchers.

They add that this shows that "neural systems supporting social perception are malleable" through the use of PRT.

The girl showed greater posttreatment activation in 2 regions of the left fisuform gyrus and a portion of the left dorsolateral prefrontal cortex. The boy showed greater activation in a portion of the right posterior superior temporal sulcus, the left ventrolateral prefrontal cortex, and both the left and right fusiform gyri.

"Both children showed increased activation in portions of State and Trait, but not Compensatory regions after treatment," write the investigators.

Coinvestigator Kevin A. Pelphrey, PhD, also from the Yale Child Study Center, noted in a release that the overall results "were not homogeneous because ASD is a multifaceted disorder that has a unique effect on each child."

"Both the children in our study made progress, but their degree of progress and level of skills at the end of treatment were distinct," he said.

Early Treatment Is Effective

"I think the take-away message is that interventions are effective. And we think, based on the results of our study, that interventions can even modify brain functioning and alter development," said Dr. Ventola.

"It can help these children to develop the core social communication skills that are the hallmark deficits in autism. It's very hopeful, as we're altering their behavior in a positive way."

Dr. Volkmar added that although this journal article focused on only 2 children, "we have a number of cases done now. So we'll obviously publish a broader series in the future."

"We're trying, in a very slow and careful way, to do something that is strongly scientific and evidence-based. Our initial findings show that kids are doing better — but again, not everyone is doing better. So I think it's important to never overpromise parents," he said.

"For now, I think the main thing, especially for pediatricians, family practitioners, and primary care providers, is to be aware of how important early detection and treatment of autism is. And what a difference it can make."

The study was supported by the Harris Professorship at the Yale Child Study Center and Allied World and by a grant from the National Institute of Mental Health. The study authors have disclosed no relevant financial relationships.

4.  Supercomputer simulations studied to improve helmets. 

http://www.rdmag.com/sites/rdmag.com/files/legacyimages/RD/News/2012/11/tbi2x500.jpg

These computer simulations contain a computer model of a human's head viewed from above looking down (top row) and from the side (bottom row). The images show the deposition of compressive energy in the brain during frontal, rear, and side blasts. These models combined with University of New Mexico's clinical observations are being used to identify energy thresholds that should lead to better military and sports helmet designs.

Researchers at Sandia National Laboratories and the University of New Mexico are comparing supercomputer simulations of blast waves on the brain with clinical studies of veterans suffering from mild traumatic brain injuries (TBIs) to help improve helmet designs.

Paul Taylor and John Ludwigsen of Sandia's Terminal Ballistics Technology Department and Corey Ford, a neurologist at UNM's Health Sciences Center, are in the final year of a four-year study of mild TBI funded by the Office of Naval Research.

The team hopes to identify threshold levels of stress and energy on which better military and sports helmet designs could be based. They could be used to program sensors placed on helmets to show whether a blast is strong enough to cause TBI.

Many TBI sufferers experience no or subtle immediate symptoms that may keep them from seeking medical attention. The sensors could alert them to a potential problem.

 

The study is the only TBI research that combines computer modeling and simulation of the physical effects of a blast with analyses of clinical magnetic resonance images (MRIs) of patients who suffer such injuries, Taylor says.

Immediately following blast waves, soldiers can suffer brief losses of consciousness, but more damage evolves weeks later, Ford says. The symptoms—headaches, memory loss, mood disorders, depression, and cognitive problems—can prevent sufferers from working, he says.

Taylor is applying shock wave physics to understand how sensitive brain tissue is affected by waves from roadside bombs or blunt impacts within the first 5 to 10 milliseconds. That’s before a victim's head moves any significant distance in response to the blast.

"This stuff is over before you have any chance to react and probably before you even knew it happened to you," Taylor says. Humans' fastest reaction times as teenagers are 75 to 100 milliseconds.

Ford says levels of energy transmitted into the brain by a blast wave "could be part of the injury mechanism associated with TBI and the mechanism by which it happens may not be mitigated by traditional methods of protecting the head with a helmet."

At Sandia, researchers created a computer model of a man's head and neck. The model includes the jaw—another first in TBI research—because a lot of blasts come from improvised explosive devices (IEDs) at ground level, sending waves traveling at the speed of sound through the jaw and facial structure before they reach the brain, Taylor says.

Sandia's team used the National Library of Medicine's Visible Human Project, which was established in 1989 to build a digital image library of volumetric data representing complete, normal adult male and female anatomy.

Using images of the male, whose age was close to that of most military personnel, Taylor, with Ford as a medical consultant, created geometric models of the seven tissue types in the human head—scalp, bone, white and gray brain matter, membranes, cerebral spinal fluid, and air spaces. Over a year, they catalogued each of the tissue types seen in about 300 "slices" of the cadaver's head, dividing what they saw into one-millimeter cubes and assigning each a tissue type for the computer simulation.

Taylor also imported digitally processed, computed tomography (CT) scans of various helmet designs into the simulations to assess the protective merits of each against blast loading.

In a typical blast simulation, 96 processors on Sandia's Red Sky supercomputer take about a day to process a millisecond of simulated time and at least 5 milliseconds are required to capture a single blast event, Taylor says.

The 3D simulations are visualized using 2D multi-colored images of a man's head that record an enormous amount of data. Taylor and Ford have focused on three types of energy entering the brain that may cause TBI: compressive isotropic energy associated with crushing; tensile isotropic energy that tends to expand parts of the brain and could lead to cavitation; and shear energy that causes distortion and tearing of soft tissue. The pressure and stress within the brain show up as colors moving in slow motion through and around the brain cavity on videos created from the simulations.

On the clinical side, Ford studied 13 subjects who suffered mild TBI after IEDs exploded near them. Some were stunned, most lost consciousness at least briefly, and most cannot hold a job, he says.

The research partners hope to recruit more patients, especially military veterans, who were exposed to blasts that did not penetrate the skin and who suffered a loss of consciousness, Ford says. Candidates must have no other history of significant blunt traumas.

A battery of tests measured the subjects' memory, language, and intelligence. These results were correlated with changes in functional magnetic resonance imaging (fMRI) from the patients. The 3D fMRI studies can detect and map networks in the brain used for processes like movement, vision, and attention. By comparing this data with those of a control group, Ford identified a subgroup of networks displaying abnormal brain activity in the patients. These results were then compared with energy deposition maps predicted by the computer simulations.

The research showed that certain regions of patients' brains are hyperactive, perhaps because they are compensating for adjacent, damaged areas of the brain that were hit with high energy from the blasts. The hyperactive regions are those that experienced the least shear and tensile energies, according to the computer simulations, which can be used to predict where the hyperactivity will likely occur, they say.

The studies also showed problems with how the patients used visual information, which corresponded to their complaints about having difficulty with attention spans, Ford says.

"This is our way to validate what the simulation shows with the clinical reality," he says.

Once Taylor and Ford determine exactly how and where the wave energy deposited in the brain gives rise to injuries, they can provide thresholds of stress and energy levels that cause TBI for consideration by helmet designers, Taylor says.

"I want us to be able to understand the physical mechanisms that lead to TBI. It would also be useful if we could make the connection between blast loading and blunt impact trauma," Taylor says. "Once we understand that we can be more comprehensive in how we protect both our warfighters and athletes against these sorts of injuries."

• AAMC Unveils News and Advocacy App
• Ad Calls for Sustained Medical Research Funding
• Report Examines Role of Chief Diversity Officers
• Council Change to Strengthen Faculty Voices
• Comments Focus on Enhancing Community-Engaged Research
• On the Move


The next edition of STAT will arrive on Dec. 3.  Happy Thanksgiving from the AAMC!


AAMC Unveils News and Advocacy App

The AAMC has launched AAMCAction, the first app to provide mobile access to the association’s news and publications, and convenient information on national issues affecting medical schools and teaching hospitals.  Users will be able to view AAMC publications, including STAT, Washington Highlights, and CASMail, as well as advocacy updates and resources.  Future releases of AAMCAction will feature push notifications to notify users of AAMC news in real time.  The app is available for iPhones and iPads (via the App Store), and for Android users (via Google Play).  To learn more, visit https://www.aamc.org/advocacy/aamcaction/.


Ad Calls for Sustained Medical Research Funding

With the National Institutes of Health facing a 10 percent budget cut under sequestration scheduled for early January, the AAMC launched an ad last week calling for sustained funding for medical research.  Appearing in The Hill, Roll Call, and Politico, the ad warns that unless Congress acts, the cuts could “delay medical progress that could help millions of patients and their families for years to come.”  To view the ad, visit https://www.aamc.org/initiatives/researchmeanshope/.


Report Examines Role of Chief Diversity Officers

A new joint report issued by the AAMC and the American Hospital Association serves as a reference to hospitals on how to design and implement effective chief diversity officer (CDO) roles in their organizations.  The Role of the Chief Diversity Officer in Academic Health Centers includes results from discussion groups on the complexities and challenges of the role, an overview of seven essential competencies, a checklist to assist executives in developing the CDO position, as well as compensation data.


Council Change to Strengthen Faculty Voices

The AAMC’s Council of Academic Societies (CAS) will transition to the Council of Faculty and Academic Societies (CFAS) beginning July 1, 2013.  The revised membership structure, one of several major changes the CAS Administrative Board proposed at the AAMC Assembly during the annual meeting, is intended to strengthen faculty voices within the AAMC. In addition to the current two representatives from each of the nearly 90 academic societies, each medical school will appoint, in consultation with internal faculty bodies, two faculty representatives: one faculty member within 10 years of initial career faculty appointment, and the other a department chair or a comparable faculty leader.  For more information about CAS, visit https://www.aamc.org/members/cas/.



Comments Focus on Enhancing Community-Engaged Research

In a recent comment letter, the AAMC affirmed that community-engagement research is an essential pillar of translational research and strategic investment in and assessment of the Clinical Translational Science Awards (CTSA) community engagement infrastructure is crucial for success.  Given the longstanding recognition by the National Center for Advancing Translational Sciences that community engagement plays a critical role in fostering research collaboratives and partnerships and building public trust in clinical and translational research, the request sought comments on the development of a research agenda that would leverage the community engagement capability of the CTSA institutions.  The AAMC also suggested that the science of community engagement and the development of an evidence base of best practices could be accelerated by comprehensive, rigorous evaluations created in partnership with communities.  To read the full letter, visit https://www.aamc.org/advocacy/library/.


On the Move

Dear Stan,

ChemLab Boot Camp chronicles the experiences of 14 real MIT freshmen as they get their first taste of working in MIT chemistry labs through a four-week January course called 5.301 Chemistry Laboratory Techniques.

In Episode 10 - The Killing Curve: The students test their antibiotics on E. Coli bacteria. Even though Jason and Julie are working together, they don't seem to have forgotten their battle over the biggest crystal.

Watch ChemLab Boot Camp's Episode 10 - The Killing Curve.

MIT OpenCourseWare's ChemLab Boot Camp - Episode 10.

The 2-5 minute episodes, shot in a style that mixes the geek fun of open educational resources with the immediacy of reality TV, bring viewers closer to the experience of being an MIT student. The videos are part of a broader effort funded by The Dow Chemical Company to foster interest in science and engineering careers.

Did you miss Episode 9 - Roses and Death? Catch it and previous episodes and bonus videos here.

10.  Marginalia:  They say it’s the most fun you can legally have with Zip Codes. 

Let’s just say, hypothetically, of course, that you are doing a study of intestinal parasites of dogs, and let’s just say, hypothetically, again, that you’ve collected 30 fecal samples of dogs from each of 3 different dog parks, located in 3 different zip codes.  Suppose that you would like to compare the median incomes in those zip codes where you’ve collected fecal samples of dogs, in order to get an idea as to the relative wealth of the residents of each of those zip codes.

 

All you have to do is go to http://zipwho.com/ , and key in each of the zip codes. For the samples mentioned in Article #1, the three collection sites were Overton Bark (38104), Shelby Farms (38134), and Johnson Park (38017).  Here’s a graph of the median incomes:
